Explore 7 Climate Change Solutions

In this lesson, students will use a jigsaw activity to learn about some of the most effective strategies and technologies that can help head off the worst effects of global warming.

By Natalie Proulx

Lesson Overview

Earlier this summer, a report issued by the Intergovernmental Panel on Climate Change , a body of scientists convened by the United Nations, found that some devastating impacts of global warming were unavoidable. But there is still a short window to stop things from getting even worse.

This report will be central at COP26 , the international climate summit where about 20,000 heads of state, diplomats and activists are meeting in person this week to set new targets for cutting emissions from coal, oil and gas that are heating the planet.

In this lesson, you will learn about seven ways we can slow down climate change and head off some of its most catastrophic consequences while we still have time. Using a jigsaw activity , you’ll become an expert in one of these strategies or technologies and share what you learn with your classmates. Then, you will develop your own climate plan and consider ways you can make a difference based on your new knowledge.

What do you know about the ways the world can slow climate change? Start by making a list of strategies, technologies or policies that could help solve the climate crisis.

Which of your ideas do you think could have the biggest impact on climate change? Circle what you think might be the top three.

Now, test your knowledge by taking this 2017 interactive quiz:

How Much Do You Know About Solving Global Warming?

A new book presents 100 potential solutions. Can you figure out which ones are top ranked?

After you’ve finished, reflect on your own in writing or in discussion with a partner:

What solutions to climate change did you learn about that you didn’t know before?

Were you surprised by any of the answers in the quiz? If so, which ones and why?

What questions do you still have about solving climate change?

Jigsaw Activity

As you learned in the warm-up, there are many possible ways to mitigate the worst effects of climate change. Below we’ve rounded up seven of the most effective solutions, many of which you may have been introduced to in the quiz above.

In this jigsaw activity, you’ll become an expert in one of the climate solutions listed below and then present what you learned to your classmates. Teachers may assign a student or small group to each topic, or allow them to choose. Students, read at least one of the linked articles on your topic; you can also use that article as a jumping-off point for more research.

Climate Change Solutions

Renewable energy: Scientists agree that to avoid the most catastrophic effects of climate change, countries must immediately move away from dirty energy sources like coal, oil and gas, and instead turn to renewable energy sources like wind, solar or nuclear power. Read about the potent possibilities of one of these producers, offshore wind farms , and see how they operate .

Refrigerants: It’s not the most exciting solution to climate change, but it is one of the most effective. Read about how making refrigerants, like air-conditioners, more efficient could eliminate a full degree Celsius of warming by 2100.

Transportation: Across the globe, governments are focused on limiting one of the world’s biggest sources of pollution: gasoline-powered cars. Read about the promises and challenges of electric vehicles or about how countries are rethinking their transit systems .

Methane emissions: You hear a lot about the need to reduce carbon dioxide in the atmosphere, but what about its dangerous cousin, methane? Read about ideas to halt methane emissions and why doing so could be powerful in the short-term fight against climate change.

Agriculture: Efforts to limit global warming often target fossil fuels, but cutting greenhouse gases from food production is urgent, too, research says. Read about four fixes to earth’s food supply that could go a long way.

Nature conservation: Scientists agree that reversing biodiversity loss is a crucial way to slow climate change. Read about how protecting and restoring nature can help cool the planet or about how Indigenous communities could lead the way .

Carbon capture: Eliminating emissions alone may not be enough to avoid some of the worst effects of climate change, so some companies are investing in technology that sucks carbon dioxide out of the air. Learn more about so-called engineered carbon removal .

Questions to Consider

As you read about your climate solution, respond to the questions below. You can record your answers in this graphic organizer (PDF).

1. What is the solution? How does it work?

2. What problem related to climate change does this strategy address?

3. What effect could it have on global warming?

4. Compared with other ways to mitigate climate change, how effective is this one? Why?

5. What are the limitations of this solution?

6. What are some of the challenges or risks (political, social, economic or technical) of this idea?

7. What further questions do you have about this strategy?

When you’ve finished, you’ll meet in “teaching groups” with at least one expert in each of the other climate solutions. Share what you know about your topic with your classmates and record what you learn from them in your graphic organizer .

Going Further

Option 1: Develop a climate plan.

Scientists say that in order to prevent the average global temperature from rising more than 1.5 degrees Celsius, the threshold beyond which the dangers of global warming grow immensely, we will need to enact all of the solutions you learned about — and more. However, the reality is that countries won’t be able to right away. They will have to consider which can have the biggest or fastest impact on climate change, which are the most cost-effective and which are the most politically and socially feasible.

Imagine you have been asked to come up with a plan to address climate change. If you were in charge, which of these seven solutions would you prioritize and why? You might start by ranking the solutions you learned about from the most effective or urgent to the least.

Then, write a proposal for your plan that responds to the following questions:

What top three solutions are priorities? That is, which do you think are the most urgent to tackle right away and the most effective at slowing global warming?

Explain your decisions. According to your research — the articles you read and the quiz you took in the beginning of the lesson — why should these solutions take precedence?

How might you incentivize companies and citizens to embrace these changes? For some ideas, you might read more about the climate policies countries around the world have adopted to help reduce greenhouse gas emissions.

Option 2: Take action.

Thinking about climate change solutions on such a big scale can be overwhelming, but there are things you can do in your own life and in your community to make a difference. Choose one of the activities below to take action on, or come up with one of your own:

Share climate solutions via media. Often, the news media focuses more on climate change problems than solutions. Counteract this narrative by creating something for publication related to one or more of the solutions you learned about. For example, you could submit a letter to the editor , write an article for your school newspaper, enter a piece in one of our upcoming student contests or create an infographic to share on social media .

Make changes in your own life. How can you make good climate choices related to one or more of the topics you learned about? For example, you could eat less meat, take public transportation or turn off your air-conditioner. Write a plan, explaining what you will do (or what you are already doing) and how it could help mitigate climate change, according to the research.

Join a movement. This guest essay urges people to focus on systems, not themselves. What groups could you get involved with that are working toward some of the solutions you learned about? Identify at least one group, either local, national or international, and one way you could support it. Or, if you’re old enough to vote, consider a local, state or federal politician you would like to support based on his or her climate policies.

10 Solutions for Climate Change

Ten possibilities for staving off catastrophic climate change

By David Biello

Mark Garlick Getty Images

The enormity of global warming can be daunting and dispiriting. What can one person, or even one nation, do on their own to slow and reverse climate change ? But just as ecologist Stephen Pacala and physicist Robert Socolow, both at Princeton University, came up with 15 so-called " wedges " for nations to utilize toward this goal—each of which is challenging but feasible and, in some combination, could reduce greenhouse gas emissions to safer levels —there are personal lifestyle changes that you can make too that, in some combination, can help reduce your carbon impact. Not all are right for everybody. Some you may already be doing or absolutely abhor. But implementing just a few of them could make a difference.

Forego Fossil Fuels —The first challenge is eliminating the burning of coal , oil and, eventually, natural gas. This is perhaps the most daunting challenge as denizens of richer nations literally eat, wear, work, play and even sleep on the products made from such fossilized sunshine. And citizens of developing nations want and arguably deserve the same comforts, which are largely thanks to the energy stored in such fuels.

Oil is the lubricant of the global economy, hidden inside such ubiquitous items as plastic and corn, and fundamental to the transportation of both consumers and goods. Coal is the substrate, supplying roughly half of the electricity used in the U.S. and nearly that much worldwide—a percentage that is likely to grow, according to the International Energy Agency. There are no perfect solutions for reducing dependence on fossil fuels (for example, carbon neutral biofuels can drive up the price of food and lead to forest destruction, and while nuclear power does not emit greenhouse gases, it does produce radioactive waste), but every bit counts.

So try to employ alternatives when possible—plant-derived plastics, biodiesel, wind power—and to invest in the change, be it by divesting from oil stocks or investing in companies practicing carbon capture and storage.

Infrastructure Upgrade —Buildings worldwide contribute around one third of all greenhouse gas emissions (43 percent in the U.S. alone), even though investing in thicker insulation and other cost-effective, temperature-regulating steps can save money in the long run. Electric grids are at capacity or overloaded, but power demands continue to rise. And bad roads can lower the fuel economy of even the most efficient vehicle. Investing in new infrastructure, or radically upgrading existing highways and transmission lines, would help cut greenhouse gas emissions and drive economic growth in developing countries.

Of course, it takes a lot of cement, a major source of greenhouse gas emissions, to construct new buildings and roads. The U.S. alone contributed 50.7 million metric tons of carbon dioxide to the atmosphere in 2005 from cement production, which requires heating limestone and other ingredients to 1,450 degrees Celsius (2,642 degrees Fahrenheit). Mining copper and other elements needed for electrical wiring and transmission also causes globe-warming pollution.

But energy-efficient buildings and improved cement-making processes (such as using alternative fuels to fire up the kiln) could reduce greenhouse gas emissions in the developed world and prevent them in the developing world.

Move Closer to Work —Transportation is the second leading source of greenhouse gas emissions in the U.S. (burning a single gallon of gasoline produces 20 pounds of CO 2 ). But it doesn't have to be that way.

One way to dramatically curtail transportation fuel needs is to move closer to work, use mass transit, or switch to walking, cycling or some other mode of transport that does not require anything other than human energy. There is also the option of working from home and telecommuting several days a week.

Cutting down on long-distance travel would also help, most notably airplane flights, which are one of the fastest growing sources of greenhouse gas emissions and a source that arguably releases such emissions in the worst possible spot (higher in the atmosphere). Flights are also one of the few sources of globe-warming pollution for which there isn't already a viable alternative: jets rely on kerosene, because it packs the most energy per pound, allowing them to travel far and fast, yet it takes roughly 10 gallons of oil to make one gallon of JetA fuel. Restricting flying to only critical, long-distance trips—in many parts of the world, trains can replace planes for short- to medium-distance trips—would help curb airplane emissions.

Consume Less —The easiest way to cut back on greenhouse gas emissions is simply to buy less stuff. Whether by forgoing an automobile or employing a reusable grocery sack, cutting back on consumption results in fewer fossil fuels being burned to extract, produce and ship products around the globe.

Think green when making purchases. For instance, if you are in the market for a new car, buy one that will last the longest and have the least impact on the environment. Thus, a used vehicle with a hybrid engine offers superior fuel efficiency over the long haul while saving the environmental impact of new car manufacture.

Paradoxically, when purchasing essentials, such as groceries, buying in bulk can reduce the amount of packaging—plastic wrapping, cardboard boxes and other unnecessary materials. Sometimes buying more means consuming less.

Be Efficient —A potentially simpler and even bigger impact can be made by doing more with less. Citizens of many developed countries are profligate wasters of energy, whether by speeding in a gas-guzzling sport-utility vehicle or leaving the lights on when not in a room.

Good driving—and good car maintenance, such as making sure tires are properly inflated—can limit the amount of greenhouse gas emissions from a vehicle and, perhaps more importantly, lower the frequency of payment at the pump.

Similarly, employing more efficient refrigerators, air conditioners and other appliances, such as those rated highly under the U.S. Environmental Protection Agency's Energy Star program, can cut electric bills while something as simple as weatherproofing the windows of a home can reduce heating and cooling bills. Such efforts can also be usefully employed at work, whether that means installing more efficient turbines at the power plant or turning the lights off when you leave the office .

Eat Smart, Go Vegetarian? —Corn grown in the U.S. requires barrels of oil for the fertilizer to grow it and the diesel fuel to harvest and transport it. Some grocery stores stock organic produce that do not require such fertilizers, but it is often shipped from halfway across the globe. And meat, whether beef, chicken or pork, requires pounds of feed to produce a pound of protein.

Choosing food items that balance nutrition, taste and ecological impact is no easy task. Foodstuffs often bear some nutritional information, but there is little to reveal how far a head of lettuce, for example, has traveled.

University of Chicago researchers estimate that each meat-eating American produces 1.5 tons more greenhouse gases through their food choice than do their vegetarian peers. It would also take far less land to grow the crops necessary to feed humans than livestock, allowing more room for planting trees.

Stop Cutting Down Trees —Every year, 33 million acres of forests are cut down . Timber harvesting in the tropics alone contributes 1.5 billion metric tons of carbon to the atmosphere. That represents 20 percent of human-made greenhouse gas emissions and a source that could be avoided relatively easily.

Improved agricultural practices along with paper recycling and forest management—balancing the amount of wood taken out with the amount of new trees growing—could quickly eliminate this significant chunk of emissions.

And when purchasing wood products, such as furniture or flooring, buy used goods or, failing that, wood certified to have been sustainably harvested. The Amazon and other forests are not just the lungs of the earth, they may also be humanity's best short-term hope for limiting climate change.

Unplug —Believe it or not, U.S. citizens spend more money on electricity to power devices when off than when on. Televisions, stereo equipment, computers, battery chargers and a host of other gadgets and appliances consume more energy when seemingly switched off, so unplug them instead.

Purchasing energy-efficient gadgets can also save both energy and money—and thus prevent more greenhouse gas emissions. To take but one example, efficient battery chargers could save more than one billion kilowatt-hours of electricity—$100 million at today's electricity prices—and thus prevent the release of more than one million metric tons of greenhouse gases.

Swapping old incandescent lightbulbs for more efficient replacements, such as compact fluorescents (warning: these lightbulbs contain mercury and must be properly disposed of at the end of their long life), would save billions of kilowatt-hours. In fact, according to the EPA, replacing just one incandescent lightbulb in every American home would save enough energy to provide electricity to three million American homes.

One Child —There are at least 6.6 billion people living today, a number that is predicted by the United Nations to grow to at least nine billion by mid-century. The U.N. Environmental Program estimates that it requires 54 acres to sustain an average human being today—food, clothing and other resources extracted from the planet. Continuing such population growth seems unsustainable.

Falling birth rates in some developed and developing countries (a significant portion of which are due to government-imposed limits on the number of children a couple can have) have begun to reduce or reverse the population explosion. It remains unclear how many people the planet can comfortably sustain, but it is clear that per capita energy consumption must go down if climate change is to be controlled.

Ultimately, a one child per couple rule is not sustainable either and there is no perfect number for human population. But it is clear that more humans means more greenhouse gas emissions.

Future Fuels —Replacing fossil fuels may prove the great challenge of the 21st century. Many contenders exist, ranging from ethanol derived from crops to hydrogen electrolyzed out of water, but all of them have some drawbacks, too, and none are immediately available at the scale needed.

Biofuels can have a host of negative impacts, from driving up food prices to sucking up more energy than they produce. Hydrogen must be created, requiring either reforming natural gas or electricity to crack water molecules. Biodiesel hybrid electric vehicles (that can plug into the grid overnight) may offer the best transportation solution in the short term, given the energy density of diesel and the carbon neutral ramifications of fuel from plants as well as the emissions of electric engines. A recent study found that the present amount of electricity generation in the U.S. could provide enough energy for the country's entire fleet of automobiles to switch to plug-in hybrids , reducing greenhouse gas emissions in the process.

But plug-in hybrids would still rely on electricity, now predominantly generated by burning dirty coal. Massive investment in low-emission energy generation, whether solar-thermal power or nuclear fission , would be required to radically reduce greenhouse gas emissions. And even more speculative energy sources—hyperefficient photovoltaic cells, solar energy stations in orbit or even fusion—may ultimately be required.

The solutions above offer the outline of a plan to personally avoid contributing to global warming. But should such individual and national efforts fail, there is another, potentially desperate solution:

Experiment Earth —Climate change represents humanity's first planetwide experiment. But, if all else fails, it may not be the last. So-called geoengineering , radical interventions to either block sunlight or reduce greenhouse gases, is a potential last resort for addressing the challenge of climate change.

Among the ideas: releasing sulfate particles in the air to mimic the cooling effects of a massive volcanic eruption; placing millions of small mirrors or lenses in space to deflect sunlight; covering portions of the planet with reflective films to bounce sunlight back into space; fertilizing the oceans with iron or other nutrients to enable plankton to absorb more carbon; and increasing cloud cover or the reflectivity of clouds that already form.

All may have unintended consequences, making the solution worse than the original problem. But it is clear that at least some form of geoengineering will likely be required: capturing carbon dioxide before it is released and storing it in some fashion, either deep beneath the earth, at the bottom of the ocean or in carbonate minerals. Such carbon capture and storage is critical to any serious effort to combat climate change.

What are the solutions to climate change?

Climate change is already an urgent threat to millions of lives – but there are solutions. From changing how we get our energy to limiting deforestation, here are some of the key solutions to climate change.

Climate change is happening now, and it’s the most serious threat to life on our planet. Luckily, there are plenty of solutions to climate change and they are well-understood.

In 2015, world leaders signed a major treaty called the Paris agreement  to put these solutions into practice.

Core to all climate change solutions is reducing greenhouse gas emissions , which must get to zero as soon as possible.

Because both forests and oceans play vitally important roles in regulating our climate, increasing the natural ability of forests and oceans to absorb carbon dioxide can also help stop global warming.

The main ways to stop climate change are to pressure government and business to:

• Keep fossil fuels in the ground . Fossil fuels include coal, oil and gas – and the more that are extracted and burned, the worse climate change will get. All countries need to move their economies away from fossil fuels as soon as possible.
• Invest in renewable energy . Changing our main energy sources to clean and renewable energy is the best way to stop using fossil fuels. These include technologies like solar, wind, wave, tidal and geothermal power.
• Switch to sustainable transport . Petrol and diesel vehicles, planes and ships use fossil fuels. Reducing car use, switching to electric vehicles and minimising plane travel will not only help stop climate change, it will reduce air pollution too.
• Help us keep our homes cosy . Homes shouldn’t be draughty and cold – it’s a waste of money, and miserable in the winter. The government can help households heat our homes in a green way – such as by insulating walls and roofs and switching away from oil or gas boilers to heat pumps .
• Improve farming and encourage vegan diets . One of the best ways for individuals to help stop climate change is by reducing their meat and dairy consumption, or by going fully vegan. Businesses and food retailers can improve farming practices and provide more plant-based products to help people make the shift.
• Restore nature to absorb more carbon . The natural world is very good at cleaning up our emissions, but we need to look after it. Planting trees in the right places or giving land back to nature through ‘rewilding’ schemes is a good place to start. This is because photosynthesising plants draw down carbon dioxide as they grow, locking it away in soils.
• Protect forests like the Amazon . Forests are crucial in the fight against climate change, and protecting them is an important climate solution. Cutting down forests on an industrial scale destroys giant trees which could be sucking up huge amounts of carbon. Yet companies destroy forests to make way for animal farming, soya or palm oil plantations. Governments can stop them by making better laws.
• Protect the oceans . Oceans also absorb large amounts of carbon dioxide from the atmosphere, which helps to keep our climate stable. But many are overfished , used for oil and gas drilling or threatened by deep sea mining. Protecting oceans and the life in them is ultimately a way to protect ourselves from climate change.
• Reduce how much people consume . Our transport, fashion, food and other lifestyle choices all have different impacts on the climate. This is often by design – fashion and technology companies, for example, will release far more products than are realistically needed. But while reducing consumption of these products might be hard, it’s most certainly worth it. Reducing overall consumption in more wealthy countries can help put less strain on the planet.
• Reduce plastic . Plastic is made from oil, and the process of extracting, refining and turning oil into plastic (or even polyester, for clothing) is surprisingly carbon-intense . It doesn’t break down quickly in nature so a lot of plastic is burned, which contributes to emissions. Demand for plastic is rising so quickly that creating and disposing of plastics will account for 17% of the global carbon budget by 2050 (this is the emissions count we need to stay within according to the Paris agreement ).

It’s easy to feel overwhelmed, and to feel that climate change is too big to solve. But we already have the answers, now it’s a question of making them happen. To work, all of these solutions need strong international cooperation between governments and businesses, including the most polluting sectors.

Individuals can also play a part by making better choices about where they get their energy, how they travel, and what food they eat. But the best way for anyone to help stop climate change is to take collective action. This means pressuring governments and corporations to change their policies and business practices.

Governments want to be re-elected. And businesses can’t survive without customers. Demanding action from them is a powerful way to make change happen.

Take action

For seven years, a government ban has blocked new onshore wind farms in England – the cheapest, cleanest energy going. With a global energy crisis and sky-high energy bills, now's the time for change. Add your name to tell Rishi Sunak to end the ban on new onshore wind projects in England.

The fossil fuel industry is blocking climate change action

Major oil and gas companies including BP, Exxon and Shell have spent hundreds of millions of pounds trying to delay or stop government policies that would have helped tackle the climate crisis.

Despite the effects of climate change becoming more and more obvious, big polluting corporations – the ones responsible for the majority of carbon emissions – continue to carry on drilling for and burning fossil fuels.

Industries including banks, car and energy companies also make profits from fossil fuels. These industries are knowingly putting money over the future of our planet and the safety of its people.

What are world leaders doing to stop climate change?

With such a huge crisis facing the entire planet, the international response should be swift and decisive. Yet progress by world governments has been achingly slow. Many commitments to reduce carbon emissions have been set, but few are binding and targets are often missed.

In Paris in 2015, world leaders from 197 countries pledged to put people first and reduce their countries’ greenhouse gas emissions. The Paris agreement has the aim of limiting global warming to well below 2ºC and ideally to 1.5°C.

If governments act swiftly on the promises they made in the Paris climate agreement, and implement the solutions now, there’s still hope of avoiding the worst consequences of climate change .

World leaders and climate negotiators meet at annual COPs – which stands for Conference of the Parties (the countries that signed the United Nations Framework Convention on Climate Change, or UNFCCC).

At COPs and other climate talks, nations take stock of their ability to meet their commitments to reduce emissions.

Recently, talks have focused on climate finance – money to help poorer countries adapt to climate change and reduce emissions. Rich countries have pledged $100 billion in annual funding to help developing countries reduce emissions and manage the impacts of climate change. This is yet to materialise, and much more money is needed.

As the impacts of climate change are increasing, important talks have also started on “loss and damage” funding. This is money needed by worst-impacted countries to deal with extreme weather and other climate change impacts.

Global climate change activism

Around the world, millions of us are taking steps to defend our climate. People of all ages and from all walks of life are desperately demanding solutions to the climate emergency.

Over the years, Greenpeace has challenged oil companies chasing new fossil fuels to extract and burn. We’ve also called out the governments for their failure to act fast enough on the climate emergency. Greenpeace activists are ordinary people taking extraordinary action, to push the solutions to climate change.

Indigenous Peoples are most severely affected by both the causes and effects of climate change . They are often on the front lines, facing down deforestation or kicking out fossil fuel industries polluting their water supplies.

Communities in the Pacific Islands are facing sea level rises and more extreme weather. But they are using their strength and resilience to demand world leaders take quicker climate action.

For many of these communities, the fight against climate change is a fight for life itself.

Even in the UK, climate change is impacting people more severely. As a country with the wealth and power to really tackle climate change, it’s never been more important to demand action.

Keep exploring

What can I do to stop climate change?

Individuals can make changes to their lives to reduce their personal carbon footprint. But it’s more important to persuade decision-makers in governments and businesses to drive emissions reductions on a much larger scale. This is the best way to stop climate change getting worse.

What is the UK doing about climate change?

All countries need to reduce their greenhouse gas emissions that contribute to global warming. So how’s the UK doing?

Renewable energy: a beginner's guide

Clean renewable energy is a vital tool for tackling climate change. Discover how it works and understand the advantages of wind, solar and water power.

Environmental justice, explained

The environmental crisis doesn't affect everyone equally. Often the worst impacts fall on those who are already most exploited by people in power. The fight for environmental justice is about addressing this unfairness, and making sure green solutions don't add to the problem.

Climate Change – Problems and Solutions Essay

Natural causes of climate change, man-made causes of climate change, the potential impact of global warming, the current impact of global warming, possible solutions to global warming, current implication of global warming solutions.

Global warming is an increasing concern in the world caused by the excessive release of greenhouse gases. It is causing a devastating impact on the environment and affecting the quality of life. Natural causes are difficult to control since they are sometimes beyond human capabilities. However, effort should be made to manage certain situations such as forest fires by responding effectively to put them off. Moreover, human activities can influence natural disasters particularly when they interfere with natural processes. Flooding may occur because of activities such as agricultural activities, urban development, deforestation, hydroelectric power, and the destruction of wetlands. Inappropriate mining can create permanent landscape modifications such as drying up of oceans while building dams can trigger earthquakes.

Humans have played a great role in climate change particularly global warming because of engaging in activities that affect the environment. Failure to prioritize environmental issues and not being concerned about the impact of human activities on the environment has continued degrading natural resources. Effective regulations should be established to hinder activities that cause the generation of carbon dioxide and other greenhouse gases. The time has come when every nation should start prioritizing environmental issues more than other factors such as economic and social.

Global warming is likely to cause a severer impact if sufficient measures are not taken to address the problem. The potential impact could affect the quality of life in a great way and cause more suffering to humans. Increasing deserts would affect the availability of food and water resulting in the development of new diseases and hunger. The potential impact could be the reduction of human and animal population, as the world becomes a harsh environment. Drying up sources of water and flooding the other areas would kill many animals and interfere with important activities such as mating.

Global warming is causing devastating effects, and worsening many disasters such as droughts, storms, and heatwaves. The warmer climate tends to retain, collect and then drop more water influencing the weather patterns to change where dry areas become drier and wet areas wetter (Price et al., 2020). The problem increases stress on the ecosystem following water shortages, pest and weed invasions, and salt invasions.

The rising cases of drought following the shortage of rainfall are threatening the lives of many people living in those regions. Extended dry seasons affect the availability of food to both humans and animals. On the other hand, rising sea levels along the coast have displaced people forcing them to move to higher regions. This is increasing pressure for resources as people move to settle in other areas. Moreover, some parts of the world such as the Midwest are experiencing extreme hot events and temperatures are likely to worsen unless sufficient measures are taken to address the problem. Extreme temperature increases health risks and influences the development of new ailments that were not common in the past.

Everybody has a role to place in the elimination of the global warming problem in the world. It is important to avoid cutting trees and reduce the utilization of energy to protect the environment. Small energy-saving practices such as unplugging gadgets, switching off lights, and using public transport can have a great impact on the reduction of global warming.

The current solutions focusing on the reduction of global warming have brought many beneficial changes and remedies. Many organizations have been developed to enhance innovation and technology in the innovation of eco-friendly machines. For instance, there has been increased investment in solar and wind energy in an attempt to reduce the use of fossil fuels. Many states have launched campaigns to educate the public on the importance of environmental conservation to create a favorable environment for future generations. People have started changing their behaviors and actions to reduce their carbon footprint.

Are there real ways to fight climate change? Yes.

Humans have the solutions to fight a global environmental crisis. Do we have the will?

The evidence that humans are causing climate change, with drastic consequences for life on the planet, is overwhelming .

Experts began raising the alarm about global warming in 1979 , a change now referred to under the broader term climate change , preferred by scientists to describe the complex shifts now affecting our planet’s weather and climate systems. Climate change encompasses not only rising average temperatures but also extreme weather events, shifting wildlife populations and habitats, rising seas , and a range of other impacts.  

Over 200 countries—193 countries plus the 27 members of the European Union—have signed the Paris Climate Agreement , a treaty created in 2015 to fight climate change on a global scale. The Intergovernmental Panel on Climate Change (IPCC), which synthesizes the scientific consensus on the issue, has set a goal of keeping warming under 2°C (3.6°F) and pursuing an even lower warming cap of 1.5 °C (2.7° F).

But no country has created policies that will keep the world below 1.5 °C, according to the Climate Action Tracker . Current emissions have the world on track to warm 2.8°C by the end of this century.  

Addressing climate change will require many solutions —there's no magic bullet. Yet nearly all of these solutions exist today. They range from worldwide changes to where we source our electricity to protecting forests from deforestation.  

The promise of new technology

Better technology will help reduce emissions from activities like manufacturing and driving.  

Scientists are working on ways to sustainably produce hydrogen, most of which is currently derived from natural gas, to feed zero-emission fuel cells for transportation and electricity.  

Renewable energy is growing, and in the U.S., a combination of wind, solar, geothermal, and other renewable sources provide 20 percen t of the nation’s electricity.  

New technological developments promise to build better batteries to store that renewable energy, engineer a smarter electric grid, and capture carbon dioxide from power plants and store it underground or turn it into valuable products such as gasoline . Some argue that nuclear power—despite concerns over safety, water use, and toxic waste—should also be part of the solution, because nuclear plants don't contribute any direct air pollution while operating.

Should we turn to geoengineering?

While halting new greenhouse gas emissions is critical, scientists say we need to extract existing carbon dioxide from the atmosphere, effectively sucking it out of the sky.  

Pulling carbon out of the atmosphere is a type of geoengineering , a science that interferes with the Earth’s natural systems, and it’s a controversial approach to fighting climate change.

Other types of geoengineering involve spraying sunlight-reflecting aerosols into the air or blocking the sun with a giant space mirror. Studies suggest we don’t know enough about the potential dangers of geoengineering to deploy it.

Restoring nature to protect the planet  

Planting trees, restoring seagrasses, and boosting the use of agricultural cover crops could help clean up significant amounts of carbon dioxide .  

The Amazon rainforest is an important reservoir of the Earth’s carbon, but a study published in 2021, showed deforestation was transforming this reservoir into a source of pollution.  

Restoring and protecting nature may provide as much as   37 percent of the climate mitigation needed to reach the Paris Agreement’s 203o targets. Protecting these ecosystems can also benefit biodiversity, providing a win-win for nature .

Adapt—or else

Communities around the world are already recognizing that adaptation must also be part of the response to climate change . From flood-prone coastal towns to regions facing increased droughts and fires, a new wave of initiatives focuses on boosting resilience . Those include managing or preventing land erosion, building microgrids and other energy systems built to withstand disruptions, and designing buildings with rising sea levels in mind.

Last year, the Inflation Reduction Act was signed into law and was a historic investment in fighting and adapting to climate change.

( Read more about how the bill will dramatically reduce emissions. )

Recent books such as Drawdown and Designing Climate Solutions have proposed bold yet simple plans for reversing our current course. The ideas vary, but the message is consistent: We already have many of the tools needed to address climate change. Some of the concepts are broad ones that governments and businesses must implement, but many other ideas involve changes that anyone can make— eating less   meat , for example, or rethinking your modes of transport .

"We have the technology today to rapidly move to a clean energy system," write the authors of Designing Climate Solutions . "And the price of that future, without counting environmental benefits, is about the same as that of a carbon-intensive future."

Climate Change: Evidence and Causes: Update 2020 (2020)

Chapter: conclusion, c onclusion.

This document explains that there are well-understood physical mechanisms by which changes in the amounts of greenhouse gases cause climate changes. It discusses the evidence that the concentrations of these gases in the atmosphere have increased and are still increasing rapidly, that climate change is occurring, and that most of the recent change is almost certainly due to emissions of greenhouse gases caused by human activities. Further climate change is inevitable; if emissions of greenhouse gases continue unabated, future changes will substantially exceed those that have occurred so far. There remains a range of estimates of the magnitude and regional expression of future change, but increases in the extremes of climate that can adversely affect natural ecosystems and human activities and infrastructure are expected.

Citizens and governments can choose among several options (or a mixture of those options) in response to this information: they can change their pattern of energy production and usage in order to limit emissions of greenhouse gases and hence the magnitude of climate changes; they can wait for changes to occur and accept the losses, damage, and suffering that arise; they can adapt to actual and expected changes as much as possible; or they can seek as yet unproven “geoengineering” solutions to counteract some of the climate changes that would otherwise occur. Each of these options has risks, attractions and costs, and what is actually done may be a mixture of these different options. Different nations and communities will vary in their vulnerability and their capacity to adapt. There is an important debate to be had about choices among these options, to decide what is best for each group or nation, and most importantly for the global population as a whole. The options have to be discussed at a global scale because in many cases those communities that are most vulnerable control few of the emissions, either past or future. Our description of the science of climate change, with both its facts and its uncertainties, is offered as a basis to inform that policy debate.

Climate change is one of the defining issues of our time. It is now more certain than ever, based on many lines of evidence, that humans are changing Earth's climate. The Royal Society and the US National Academy of Sciences, with their similar missions to promote the use of science to benefit society and to inform critical policy debates, produced the original Climate Change: Evidence and Causes in 2014. It was written and reviewed by a UK-US team of leading climate scientists. This new edition, prepared by the same author team, has been updated with the most recent climate data and scientific analyses, all of which reinforce our understanding of human-caused climate change.

Scientific information is a vital component for society to make informed decisions about how to reduce the magnitude of climate change and how to adapt to its impacts. This booklet serves as a key reference document for decision makers, policy makers, educators, and others seeking authoritative answers about the current state of climate-change science.

Growing political pressure to find solutions to climate change is leading to increasing calls for multiple disciplines, in particular those that are not traditionally part of climate change research, to contribute new knowledge systems that can offer deeper and broader insights to address the problem. Recognition of the complexity of climate change compels researchers to draw on interdisciplinary knowledge that marries natural sciences with social sciences and humanities. Yet most interdisciplinary approaches fail to adequately merge the framings of the disparate disciplines, resulting in reductionist messages that are largely devoid of context, and hence provide incomplete and misleading analysis for decision-making. For different knowledge systems to work better together toward climate solutions, we need to reframe the way questions are asked and research pursued, in order to inform action without slipping into reductionism. We suggest that interdisciplinarity needs to be rethought. This will require accepting a plurality of narratives, embracing multiple disciplinary perspectives, and shifting expectations of public messaging, and above all looking to integrate the appropriate disciplines that can help understand human systems in order to better mediate action.

1 Urgency to solve climate change

Following the launch of the Intergovernmental Panel on Climate Change (IPCC) Special Report on 1.5C (IPCC 2018 ), pressure to take action on climate change has escalated significantly (Boykoff and Pearman 2019 ). While this attention is to be welcomed, it has implications for researchers of, and research on, climate change. A clear push is evident from within both the scientific and policy communities to get scientists to move beyond merely providing knowledge about climate change, to also helping society define the solutions (Haasnoot et al.  2020 ; Callaghan et al.  2020 ). Additionally, the solutions focus mirrors—and drives—civil society pressure for governments to take action on the climate crisis (Fisher and Nasrin 2020 ). This introduces new challenges for the ways in which science on climate change is undertaken and how the knowledge gained is used in the world of practice and policy (Hulme 2020 ). In particular, the search for solutions to climate change forces us to examine the way different disciplines interact in this process, most prominently through interdisciplinary research approaches (Castree et al. 2014 ).

In response to pressure for concrete, urgent, and actionable information, however, researchers often shear away detail, and pick one of a number of alternative messages to unite behind. The emerging narrative of ‘listen to the science’ unfortunately reinforces the message that discreet, clear, and neutral solutions readily exist (Evensen 2019 ). This is underpinned by a strong belief that science needs to be represented and communicated in easy-to-digest ‘bite-size’ statements targeting a policy audience, commonly believed to be working under time duress. The growing tendency for complex scientific findings to be summarized into single sentences for policy briefs is case-in-point. These communiqués are often simplified, tend to emphasize quantitative detail, and fail to do justice to the messiness of climate change impacts as they are experienced by people and ecosystems in different parts of the globe (Castán Broto 2020 ; Hulme 2011a ). Because they also abstract from political context, they avoid grappling with the reality of implementation challenges, and reflecting essential ambiguities that would raise the level of debate and reflection.

The critique that climate change research needs to be open to ways of knowing other than the natural sciences is not new (Shah 2020 ; Heymann 2019 ; Rigg and Reyes Mason 2018 ; Victor 2015 ; Barnes et al.  2013 ; Hulme 2011a and b ; Jasanoff 2010 ), nor are the calls for interdisciplinarity (Bhaskar et al.  2010 ; Simonovic and Davies 2006 ) and inter-epistemology (Murphy 2011 ). Interdisciplinarity is understood as the collective efforts to tackle a single issue from multiple disciplinary perspectives. In particular, this cuts across the natural sciences, the social sciences, and the humanities. Our purpose here is to take that message further. We argue that in the push for solutions to climate change, knowledge on climate change is expressed in simplified and narrow ways that privileges predictive natural sciences over interpretative qualitative social sciences and humanities, even when this knowledge is generated in ostensibly interdisciplinary interactions.

Yet, because solutions are context-dependent and therefore not universal, the interpretive sciences are necessary to identify feasible and effective solutions. For example, a qualitative and locally informed assessment of vulnerability in a specific location can help avoid the maladaptation that otherwise risks resulting from poorly designed blue-print adaptation strategies (Eriksen et al.  2021 ). Consequently, we need new ways of generating and communicating knowledge on climate change through an interdisciplinarity that does not limit our visions nor narrow the evidence base needed for problems rooted in the deep relationship between the biosphere and human systems. We underscore the intricacy between interdisciplinarity and transdisciplinarity influenced by the need for policy relevance that is based on the assessment of scientific knowledge, which creates a unique context for reflection on which knowledge is needed to address the climate crisis. This commentary thus offers a cautionary tale about the consequences of conducting nominally interdisciplinary climate change research and assessment under the pressure to generate solutions. We explain why pressure for action leads to reductionist approaches, comment critically on interdisciplinarity as it is currently practised, and offer reflections on a way forward for rethinking interdisciplinarity.

2 Pressure for solutions leads to reductionism

Embracing the complexity of climate change research means reflecting both the natural and the social world, investigating the ways we give meaning to each and examining how they interact with each other. This requires conversations across disciplines to allow for answering questions that a single disciplinary lens cannot fully explain. It also means dealing with the inherent epistemic tensions between the disciplines and greater engagement with difference, which can be a source of creativity and deep learning. There is now increasing agreement that qualitative approaches and diverse ontological models are also needed to understand climate change in specific contexts (Nightingale et al. 2020 ; Goldman et al.  2018 ; Hulme 2010 ). Such perspectives bring out a more complete picture of climate change impacts, the drivers of vulnerability, and opportunities for adaptation and mitigation (Howarth et al.  2018 ). But this can lead to messy, contradictory information that is at odds with the type of evidence that decision-makers require for their applied world. For example, rather than a narrative about who is more vulnerable to climate change in a specific location, decision-makers ask for vulnerability indicators that lump diverse populations together in typologies, forcing categorization even when some individuals would span multiple categories. As a consequence, there remains a strong tendency to focus on reductionist messages, i.e. ‘clean’ narratives that offer discreet pathways (Rigg and Reyes Mason 2018 ), by definition excluding alternative, conflicting approaches that stem from diverse knowledges, including indigenous knowledge (Murphy 2011 ; Ford et al.  2016 ; Farbotko and Lazrus 2012 ). To illustrate these points, we examine two ways in which current representations of climate change knowledge sideline interpretivist disciplines: the way that numbers embody the process of reductionism, and how lack of epistemological diversity also reinforces reductionism and prevents interdisciplinarity from taking place.

2.1 Numbers—not stories

Visual representations of science have a long history (Trumbo 2000 ). Numbers and graphics, which underpin such representations, undoubtedly have an impact in policy conversations, particularly by concretizing complicated information for non-experts and are frequently seen as a way to convey both quantitative and qualitative knowledge on climate change. The result is that often numbers get prioritized over stories. Indeed, the desire by governments for IPCC figures to express ideas simply (Thoni and Livingston 2019 ) suggests that decision-makers are attuned to reductionist messages to help them navigate the masses of climate change knowledge. This is problematic, as both graphics and numbers can oversimplify intricacy of science, and thereby become misused or misunderstood. One example is when the IPCC 1.5 °C report was widely misrepresented as saying that there were 12 years left to act to avert the climate catastrophe. In fact, the report stated that in order to stay under 1.5 °C warming, CO 2 emissions needed to be reduced by half by or before 2030 (i.e. 12 years away from 2018). This led to confusion about when and how to take policy action (Allen 2019 ; Boykoff and Pearman 2019 ; Dubash 2020 ), exacerbating climate anxieties and extreme views, increasing the political polarization on climate change, and generating friction among scientists regarding the most suitable way to frame climate change in communication.

The UNEP Gap Report produced annually since 2010 provides a good illustration of both the power and pitfalls of non-contextual quantitative representation (UNEP 2019 ; Höhne et al.  2020 ). The articulation of an emissions ‘gap’ has been a politically powerful tool, communicated through one number—the Gigaton gap—and one iconic figure with a range of scenarios. Each report provides examples of promising sectoral actions—energy efficiency, land use, urbanization, and more—to fill this gap. Yet, in each subsequent year, the gap has remained and even grown, leaving unasked, and unanswered, why mitigation potential does not seem to be realized. To do so would require going beyond the discussion of an emissions gap, rooted in science, modelling, and technology, to perhaps examine an ‘implementation gap’, focused on politics, policy studies, sociology, and anthropology. Specifically, it would require understanding, at minimum, the national and local politics of realizing low-carbon transitions, the institutions required to oversee those transitions, and the behavioural changes needed at the level of citizens. But these questions, and their answers, are not amenable to reductionist analysis or acontextual answers.

2.2 (Lack of) epistemological diversity

Since the 1st Assessment Report, published in 1990, the IPCC has come a long way toward diversifying the disciplines in authors, starting with only a handful of scholars outside of the natural sciences, to a more even balance across the Sixth Assessment Report (AR6) with authors, including Coordinating Lead Authors, stemming from both social sciences and humanities to provide greater diversity of perspectives. This is important because Corbera et al. ( 2016 ) find that epistemological homogeneity among 5th Assessment Report Working Group III authors contributes to narrowing the range of viewpoints and understandings of solutions to climate change. Similarly, lack of disciplinary representation among IPCC authors contributes to unevenness in the literature and evidence assessed (e.g. Hulme and Mahony 2010 ). Bjurström and Polk ( 2011 : p. 543), for example, have found that the IPCC, rather than being seen as an interdisciplinary effort, was a ‘loose cooperation between disciplines with limited integration’.

But while bringing theories, methods, and practices from across the range of scholarly disciplines is one step toward interdisciplinarity (Freeth and Caniglia 2020 ), these efforts can fall flat when the different philosophical underpinnings—i.e. epistemological perspectives—clash and default to ‘disciplinary capture’ by a single perspective (Brister 2016 ). The problem lies with the way in which different disciplines are not provided equal opportunities to contribute to thinking about solutions in the IPCC. For example, while Working Group II is entitled ‘impacts, adaptation, and vulnerability’, vulnerability is given far less emphasis within the reports, and only became part of the focus in the Third Assessment Report in 2007. Consequently, those researchers working on vulnerability are often devalued by a perspective that emphasizes climate change impacts over the underlying drivers of vulnerability, such as poor development, gender inequality, or racism. Addressing this problem would require an acknowledgement that interdisciplinary approaches need to be a platform for epistemological diversity in order to move away from reductionism, rather than only an exercise in multi-disciplinary representation.

The politically sensitive issue of carbon removal technologies illustrates how the IPCC’s contents are influenced by the dominance of a reductionist perspective. As Vardy et al. ( 2017 ) describe, carbon dioxide removal (CDR) and solar radiation management (SRM) techniques are controversial among both scientists and decision-makers due to the considerable known and potentially unknown risks with these measures. Some have observed that by even acknowledging the literature on CDR and SRM, the IPCC was validating a potentially dangerous approach (Gardiner and Fragnière 2018 ; Frumhoff and Stephens 2018 ). However, more importantly, the qualitative knowledge on social transformations that could have accompanied the carbon removal narrative in the IPCC scenarios was ‘almost impossible’ to model in a way that would have fit with the scenarios (Vardy et al.  2017 : p. 63). Thus, by forcing the knowledge to fit into a reductionist framing, valuable understandings of human behaviour were marginalized. This sends the message that humanity can continue extracting resources and using energy at an ever-accelerating pace without acknowledging that how resources are used will need to change. Even scaling up renewable energy production and use, undoubtedly an important part of the solution to climate change that does not challenge lifestyles and consumption behaviour, can become yet another form of technofix. Knowing that the IPCC has significant influence on scientific knowledge and directions of climate change research in general (Vasileiadou et al.  2011 ; Goldman et al.  2018 ), this could also be highly worrying.

In short, the search for solution-oriented, generalizable statements to guide policy lead to an emphasis on forms of knowledge emerging from natural sciences, technology studies, and economics. These understandings do not engage with questions around the social dynamics of climate resilient futures, examined through the social sciences and humanities disciplinary lenses, which engage more with the context-specific politics and the ‘wicked’ nature of the problem, nor with the narratives found in indigenous knowledge. Yet it is precisely contextual understandings that are salient to implementation challenges, particularly in a Paris Agreement world driven by explicitly contextual ‘Nationally Determined Contributions’ to mitigation.

3 Revisiting—and rethinking—interdisciplinarity

Interdisciplinarity is the go-to, unquestioned approach to gain more diverse perspectives, because it suggests the opportunity to consider a single problem from a variety of angles, and seek answers through multiple methodologies. However, collaboration is challenged by underlying differences in research methods, and fundamental epistemological disagreements about what constitutes knowledge needed for action. Indeed, whose model of knowledge should come at the forefront of deciding how society needs to respond to climate change? One can argue that ‘such matters are not climate science’ (Bendell 2020 ), rather that these lie in the domains of political science, sociology, or other human-focused disciplines. But if the nature of the challenge lies well beyond the scope of any single discipline, as climate change does, we have little choice but to grapple with these questions jointly. This is additionally complicated by growing policy pressures to filter statements from a political feasibility perspective. As a result, interdisciplinarity is not insulated from reductionism: quite to the contrary. In an effort to overcome these communications challenges, we often relate results in the form of familiar narratives, eliminating discipline-specific terms that convey the nuances of argument or evidence within the dialect of a single discipline and much meaning is lost.

Importantly, the willingness of all disciplines working on climate change to engage with each other is not a given. Even within the social sciences, competition between how to frame problems and design research means that collaborations can struggle to bear good results (Bracken and Oughton 2006 ). These clashes have left a room for a positivist worldview to dominate, consequently devaluing qualitative sciences and knowledges rooted in diverse epistemologies. The example of how indigenous knowledge has been sidelined from IPCC reports until recently even though many Indigenous Peoples are at the frontlines of climate change (García-del-Amo et al.  2020 ; Alexander et al.  2011 ) demonstrates how ontological disconnects create hierarchies of knowledge, whereby scientific knowledge that can be empirically measured is given greater validity. Encouragingly, there are efforts to link indigenous knowledge with scientific knowledge (Alexander et al.  2011 ), most notably in the ongoing IPCC AR6. Yet, these processes should not just use indigenous knowledge to ‘validate’ empirical measurements of climate change. To represent such knowledge adequately requires shifting framings away from reductionist science and instead embracing that indigenous knowledge brings other and equally valid understandings of why climate change is happening and what consequences it has.

4 New directions for interdisciplinary climate research

We recognize the increasing importance of interdisciplinarity as the climate change crisis worsens (Mooney et al.  2013 ; Olsen et al.  2013 ). Research has already identified characteristics of effective interdisciplinary collaborations on climate change. For example, Bruine de Bruin and Morgan ( 2019 ) draw on a technique called ‘mental models’ to focus on reorienting collaborations around a common goal and a joint methodology, using improved communication between researchers and their audience, something also underscored by Leigh and Brown ( 2021 ) in their study in interdisciplinary projects. Klink et al. ( 2017 ) suggest that the key to good interdisciplinary work is continuous evaluation of how researchers interact with each other, the project and the outputs. While retaining our belief in the benefits of interdisciplinary work, and the virtues of encouraging these approaches among new generations of researchers, we also believe we have to do interdisciplinarity better. Here, we propose four interrelated components of a way forward.

First, we have to change the objective of our research from a quest for a unitary vision of the past, present, and future, toward plural and co-existing perspectives. Diverse simultaneous narratives provide greater opportunity for political creativity than single narratives. Indeed, Pearce et al. ( 2005 ) suggest that ‘dissensus’ as an entry point, rather than consensus, may allow for greater deliberative decision-making. Studies of the IPCC for example suggest that the search for consensus frequently leads IPCC documents to frame unhelpfully bland conclusions on precisely those issues that are of the greatest policy relevance, and therefore politically charged, losing an opportunity to contribute to learning and debate (Victor 2015 ; Vardy et al.  2017 ). This can stem directly from the way that natural and social scientists are forced to make compromises due to their inherently different framings (Vardy et al.  2017 ). Reflecting the co-existence of the different epistemologies grounding different disciplines allows for productive engagement by a broader cross section. For example, the idea behind large-scale implementation of renewable energy as a climate mitigation strategy needs to be framed in its wider social and environmental impacts. These may include mineral extraction as inputs for manufacturing of renewables with all their exploitative implications of poor communities upstream and land expropriation to make way for solar farms that bring localized problems in the interest of globalized solutions of emission reductions. At the point of renewable energy use, vast areas of land for the expansion of solar farms are likely to present competition over land, often occupied by poor communities, hence giving rise to localized challenges.

Second, we need to draw on more (epistemologically) diverse knowledge sources. An acceptance of contestation and contradiction requires a messier intellectual landscape of climate understanding that emerges from different disciplinary perspectives. This would acknowledge the need for ‘uncomfortable knowledge’ in policy making proposed by Rayner ( 2012 ). This means avoiding sanctifying one disciplinary formulation and instead juxtaposing multiple disciplinary formulations. This compels researchers to find new approaches to speak across disciplines, for example, not just drawing on knowledge about human behaviour that can easily be plugged into integrated assessment or other models. Our inherently diverse ways of understanding the world requires us to ask, and answer, questions in different and deeper ways. This epistemological diversity requires us to acknowledge that there are different understandings of what knowledge is, and that this influences how knowledge is constructed (Gobbo and Russo 2020 ) and whose knowledge counts (England 2015 ; Haraway 1988 ). Critically, this also implies a re-working of how researchers communicate with policymakers, the media, and the public. Expectations of definitively stated universalistic statements will need to give way to an appreciation for multiple, contextually embedded messages about future pathways and their implications.

Third, we need to invest more in qualitative research that examines human behaviour. To adequately respond to the call to action, we need to better understand the basis of human responses to climate change. In other words, we need a sound understanding of the implementation gap as much, if not more, than the emissions gap. To do so, we have to go beyond a technical understanding of the potential for mitigation and adaptation, and draw on the social sciences and humanities to explore the factors—political, sociological, and institutional—that help explain whether and how these potentials can actually be realized, as argued by Nightingale et al. ( 2020 ). A recent review shows that many adaptation projects are contributing to increased, rather than reduced, vulnerability to climate change due in part to poor understandings of local contexts where projects are being implemented (Eriksen et al.  2021 ). These findings suggest that adaptation strategies should not be prioritized based on indicators of their implementation feasibility; more important is the consideration of whether they actually reduce the impacts of climate change. Embracing contextual knowledge requires national and local understandings and, as such, works as a defence against reductionism.

Finally, we need to broaden the knowledge base for action-relevant decision-making on climate change—from the current mechanistic approach to setting targets and charting a course alone, to also creating an information base for more regular and informed course correction. Part of the answer lies in encouraging interdisciplinary approaches among new generations of climate change researchers. This also involves asking ‘who speaks for climate change?’ and lessening the focus on reductionist messages and materials. This shift in emphasis comes from a position of humility about future-looking projections, because while our collective behaviour fits certain patterns, it does not fall neatly into deterministic categories. Who could, for instance, have predicted the scale and impact of the Fridays for the Future movement, substantially stimulated by one young pioneer, a feat well-funded NGOs that have been protesting climate change for decades were not able to achieve? Or the lessons about preparedness that we are learning from the COVID-19 pandemic (e.g. Schipper et al.  2020 )? In addition to research that allows us to chart a course, we need a climate science that allows us to react flexibly to new developments, and holistically embrace the links between climate change, climate change policy action, and civil society uprisings such as the Black Lives Matter movement (e.g. Sigwalt 2020 ).

The climate debate requires careful quantitative analysis, without doubt. While there is widespread assumption that numerical values can speak a universal language, reductionist messages can easily be misunderstood and misused if they are stripped of the social and political dimensions within which they are framed—or even worse, if they emerge out of assessment that has marginalized such dimensions. We argue here that current mainstream approaches to interdisciplinarity result in limiting overall contributions from the social sciences and humanities to knowledge on climate change. First, it tends to induce all disciplines to assimilate reductionist sciences, tempted by the incentive that the resultant messages may be more palatable to natural scientists for the purposes of collaboration, consequently eliminating the richness otherwise contributed by these scholars. Second, it may alienate talented qualitative researchers who feel their work is less valued from climate change research, or who cannot find a common entry point for their knowledge. To find adequate solutions to climate change, we need to not only embrace inputs from all disciplines, but also to reframe the questions we ask and the approaches we pursue if we are to inform action without slipping into reductionist framings. To do so, this requires rethinking interdisciplinarity by welcoming a plurality of narratives, embracing multiple disciplinary perspectives, understanding human systems that mediate action better, and actively seeking knowledge that enables adaptive response to surprises.

ENCYCLOPEDIC ENTRY

Climate change.

Climate change is a long-term shift in global or regional climate patterns. Often climate change refers specifically to the rise in global temperatures from the mid-20th century to present.

Earth Science, Climatology

Fracking is a controversial form of drilling that uses high-pressure liquid to create cracks in underground shale to extract natural gas and petroleum. Carbon emissions from fossils fuels like these have been linked to global warming and climate change.

Climate is sometimes mistaken for weather. But climate is different from weather because it is measured over a long period of time, whereas weather can change from day to day, or from year to year. The climate of an area includes seasonal temperature and rainfall averages, and wind patterns. Different places have different climates. A desert, for example, is referred to as an arid climate because little water falls, as rain or snow, during the year. Other types of climate include tropical climates, which are hot and humid , and temperate climates, which have warm summers and cooler winters.

Climate change is the long-term alteration of temperature and typical weather patterns in a place. Climate change could refer to a particular location or the planet as a whole. Climate change may cause weather patterns to be less predictable. These unexpected weather patterns can make it difficult to maintain and grow crops in regions that rely on farming because expected temperature and rainfall levels can no longer be relied on. Climate change has also been connected with other damaging weather events such as more frequent and more intense hurricanes, floods, downpours, and winter storms.

In polar regions, the warming global temperatures associated with climate change have meant ice sheets and glaciers are melting at an accelerated rate from season to season. This contributes to sea levels rising in different regions of the planet. Together with expanding ocean waters due to rising temperatures, the resulting rise in sea level has begun to damage coastlines as a result of increased flooding and erosion.

The cause of current climate change is largely human activity, like burning fossil fuels , like natural gas, oil, and coal. Burning these materials releases what are called greenhouse gases into Earth’s atmosphere . There, these gases trap heat from the sun’s rays inside the atmosphere causing Earth’s average temperature to rise. This rise in the planet's temperature is called global warming. The warming of the planet impacts local and regional climates. Throughout Earth's history, climate has continually changed. When occuring naturally, this is a slow process that has taken place over hundreds and thousands of years. The human influenced climate change that is happening now is occuring at a much faster rate.

What Is Climate Change?

Climate change refers to long-term shifts in temperatures and weather patterns. Such shifts can be natural, due to changes in the sun’s activity or large volcanic eruptions. But since the 1800s, human activities have been the main driver of climate change , primarily due to the burning of fossil fuels like coal, oil and gas.

Burning fossil fuels generates greenhouse gas emissions that act like a blanket wrapped around the Earth, trapping the sun’s heat and raising temperatures.

The main greenhouse gases that are causing climate change include carbon dioxide and methane. These come from using gasoline for driving a car or coal for heating a building, for example. Clearing land and cutting down forests can also release carbon dioxide. Agriculture, oil and gas operations are major sources of methane emissions. Energy, industry, transport, buildings, agriculture and land use are among the main sectors  causing greenhouse gases.

Humans are responsible for global warming

Climate scientists have showed that humans are responsible for virtually all global heating over the last 200 years. Human activities like the ones mentioned above are causing greenhouse gases that are warming the world faster than at any time in at least the last two thousand years.

The average temperature of the Earth’s surface is now about 1.2°C warmer than it was in the late 1800s (before the industrial revolution) and warmer than at any time in the last 100,000 years. The last decade (2011-2020) was the warmest on record , and each of the last four decades has been warmer than any previous decade since 1850.

Many people think climate change mainly means warmer temperatures. But temperature rise is only the beginning of the story. Because the Earth is a system, where everything is connected, changes in one area can influence changes in all others.

The consequences of climate change now include, among others, intense droughts, water scarcity, severe fires, rising sea levels, flooding, melting polar ice, catastrophic storms and declining biodiversity.

People are experiencing climate change in diverse ways

Climate change can affect our health , ability to grow food, housing, safety and work. Some of us are already more vulnerable to climate impacts, such as people living in small island nations and other developing countries. Conditions like sea-level rise and saltwater intrusion have advanced to the point where whole communities have had to relocate, and protracted droughts are putting people at risk of famine. In the future, the number of people displaced by weather-related events is expected to rise.

Every increase in global warming matters

In a series of UN reports , thousands of scientists and government reviewers agreed that limiting global temperature rise to no more than 1.5°C would help us avoid the worst climate impacts and maintain a livable climate. Yet policies currently in place point to a 3°C temperature rise by the end of the century.

The emissions that cause climate change come from every part of the world and affect everyone, but some countries produce much more than others .The seven biggest emitters alone (China, the United States of America, India, the European Union, Indonesia, the Russian Federation, and Brazil) accounted for about half of all global greenhouse gas emissions in 2020.

Everyone must take climate action, but people and countries creating more of the problem have a greater responsibility to act first.

We face a huge challenge but already know many solutions

Many climate change solutions can deliver economic benefits while improving our lives and protecting the environment. We also have global frameworks and agreements to guide progress, such as the Sustainable Development Goals , the UN Framework Convention on Climate Change and the Paris Agreement . Three broad categories of action are: cutting emissions, adapting to climate impacts and financing required adjustments.

Switching energy systems from fossil fuels to renewables like solar or wind will reduce the emissions driving climate change. But we have to act now. While a growing number of countries is committing to net zero emissions by 2050, emissions must be cut in half by 2030 to keep warming below 1.5°C. Achieving this means huge declines in the use of coal, oil and gas: over two-thirds of today’s proven reserves of fossil fuels need to be kept in the ground by 2050 in order to prevent catastrophic levels of climate change.

Adapting to climate consequences protects people, homes, businesses, livelihoods, infrastructure and natural ecosystems. It covers current impacts and those likely in the future. Adaptation will be required everywhere, but must be prioritized now for the most vulnerable people with the fewest resources to cope with climate hazards. The rate of return can be high. Early warning systems for disasters, for instance, save lives and property, and can deliver benefits up to 10 times the initial cost.

We can pay the bill now, or pay dearly in the future

Climate action requires significant financial investments by governments and businesses. But climate inaction is vastly more expensive. One critical step is for industrialized countries to fulfil their commitment to provide $100 billion a year to developing countries so they can adapt and move towards greener economies.

Explaining the High Consumption-Based Carbon Footprints in the Nordic Countries.”  Environmental Research Communications  4, no. 12 (December 2022): 125007. https://doi.org/10.1088/2515-7620/aca871 .

The  climate movement discourse has shifted  from focusing almost exclusively on individual action to prioritizing systemic remedies at the societal, corporate, and policy levels. Organizations originally placed most of the burden on individuals to reduce pollution. The climate movement now primarily assigns responsibility for climate change to corporations and governments. This shift towards corporate responsibility, for instance, is evident in our discourse around recycling. While organizations once primarily made properly sorting recycling an individual obligation, it is now clear that recycling has minimal impacts on emission reduction, no matter how precise the sorting effort is. Furthermore, even when community members sort their trash, only a fraction is recycled. This trash crisis is a systemic failure, not an individual one. Such shortcomings have increased individual’s frustration with slow progress toward sustainability goals. Even though the  climate movement has started noting  that individual power is only secondary to the economic system, which is the real problem, new research shows that, until the government makes systemic changes, short-term individual action is still vital during the transition phase.

To keep global warming below the 2 °C limit set in the  Paris Agreement , we must considerably reduce the average carbon footprint per individual  by 2030 . However, the obligation to reduce emissions lies primarily among more affluent countries with high per-capita emissions.  Scholars estimate  that if the wealthiest 10% of individuals reduced their carbon footprint by 90%, the poorest half could increase their carbon footprint two or three-fold without exceeding the targets set in the Paris Agreement. Two recent papers published in  Environmental Research Communications  investigate how to reduce the carbon footprint of the wealthiest. The authors in both papers focus on the Nordic countries, which are among the most affluent countries and have a range of high per-capita emissions because they emit multiple times the global average of greenhouse gases. Researchers of both papers set out to identify lifestyle elements that people can alter to reduce average footprints in Nordic countries immediately. The  first paper  is a collaboration of Nordic and Polish researchers led by Jukka Heinonen. This research analyzes the effects of different consumption choices on footprints. They identify that people must institute drastic lifestyle changes simultaneously to reach the Paris Agreement’s goal. 

With the current state of industry and governments, drastic and immediate reductions in consumption are needed from Nordic people to reach a footprint low enough for the Paris Agreement.  Heinonen and his team  show that lifestyles must change in multiple areas simultaneously. For example, it is not enough for someone to sell their car and become vegan. A person would also need to stop flying to reduce their carbon footprint below the Paris Agreement’s limit in carbon footprint. Such substantive requirements to meet reduction goals illustrate that we must fundamentally change our lifestyles to follow the Paris Agreement’s accords. Therefore, if individuals want to keep their core lifestyle characteristics the same, corporations must follow suit and make these lifestyles more sustainable.

Building upon these results, the researchers of the  second paper  investigate whether people who care about the environment pollute less.  The authors found  a noticeable difference in how caring for the environment relates to pollution in different types of consumption. From these findings, we can learn which policy changes are more or less critical in the short term.

The  second paper  suggests that the methodology used by researchers in the past has mistakenly led to the conclusion that income and carbon footprint are substantially related. Intuitively, if you have more income, you generally consume more. This intuition has inspired many scientists to analyze income and carbon footprint relationships. However, the traditional method to calculate this relationship assumes the average emission per dollar spent in a category. Imagine two passengers on the same flight from New York to LA. One paid $200 for their ticket and the other $400. Logically, they have the same carbon footprint from the flight, but the latter would cause twice the emissions according to the old methodology. When you spend money on a good, it is hard to imagine all the steps that went into making it—the materials extracted and altered, energy use and labor, and the cost of transportation. A thoughtful analysis must incorporate each step’s effect without relying too generously on the assumption that expenditure and emissions are inherently related.

Improving upon these traditional methods, the researchers used unique survey data on pro-climate attitudes . They found that people with higher incomes only sometimes pollute much more, and those who care more about the environment have relatively low emissions.  The data shows  that those with 10% higher incomes pollute around 2.2% more, and those with 10% higher concern for climate change pollute about 2.1% less. What’s more, there is a considerable difference between types of consumption. In particular, people with pro-climate attitudes are likely to eat less meat, use less heating, and use more public transportation. Counterintuitively, however, they fly much more. People who are 10% more concerned fly around 27.1% more. But most notably, although those with higher incomes consume more goods and services, people consume the same amount of goods and services no matter how much they care about climate change. Manufacturers may need to drive reduced emissions since those more concerned do not compromise buying goods and services. The results suggest that in other spheres, such as food, heating, and transportation, changes could be driven by personal motivation. Even with the potential for these actions to reduce carbon emissions,  people rarely make these low-carbon choices. Further research must address the knowledge gap between high-reward climate actions and people’s resistance to adopting them. 

These studies show that we must change our lifestyles as much as possible in the short term while working on long-term systemic changes. Better-off individuals must contribute considerably to reducing climate change by changing their behavior. But they also highlight the areas where motivation and income have little (or the opposite) effect, which are the areas policymakers and corporations should focus on. The need to reduce greenhouse gas emissions is dire and time-constrained, and the solution requires both behavioral and systemic change. Many of us are idealists, believing that we may save humanity if we “just” change the global economic system. However, until we reach this elusive goal, we must change at least three fronts: policy, business, and lifestyle choices. Governments must enact ambitious, strict green policies that force corporations to alter their operations. And since governmental action is slow, corporations also must take on real corporate responsibility to get a head start. And while those changes are happening, those who are privileged and able must change their lifestyles. To increase motivation for significant change, we must design and implement bottom-up (grassroots) and top-down (governmental regulation) methods to activate lifestyle changes. This research, which decouples the assumption that income (or climate concern) and climate emissions are always correlated, encourages all members of society to consider shifting their behavior—to fly less often, reduce car travel, and eat less meat.

Ultimately, this research calls for individual action and for governments and corporations to be accountable for making measuring changes.  Studies  have made it apparent that human actions have severely increased pollution. It is fair for the humans who have contributed most to pollution to shift their behavior to reduce it. As we await systemic change,  the science  is crystal clear: lifestyle change has a climate impact, so we have a moral responsibility to make decisions that reflect this.

How do we transition to clean energy with enough speed and scale to prevent the most extreme impacts of climate change? This question loomed large for many of the speakers and participants at the Stanford Forum on the Science of Energy Transition , held on campus April 10 for an audience of students and invited guests.

To stabilize global temperatures, we need to find ways to reduce and remove our carbon emissions from Earth’s atmosphere by tens of gigatons every single year. By comparison, gas-powered vehicles in the U.S. together produce about a gigaton of carbon dioxide emissions each year.

Many of the speakers agreed action over the next few decades is critical, and addressing climate change will require coordinated efforts across the scientific community, climate technology innovators, government, the private sector, and others to transition the world’s $100 trillion economy to clean energy.

The forum, co-hosted by the Stanford Doerr School of Sustainability and Stanford Management Company , convened experts to explore challenges and opportunities to transform the power grid, rethink renewable fuels, remove greenhouse gases from our atmosphere, and address energy issues in tandem with other sustainability concerns.

The forum served as a powerful example of how Stanford leaders are educating changemakers in energy and facilitating connections that will help bring insights from scientific research to decisions that will affect global sustainability.

“Today, the energy transition will require us to forge new pathways, but we can’t just blindly strike out. That will lead us down too many dead ends, and time is of the essence. Instead, the paths we choose must be informed by science,” said Robert Wallace, the chief executive officer of Stanford Management Company.

Consider speed and scale from the get-go

Decarbonizing global energy production is a tall order. That’s before you consider the rising demand for energy as countries develop and look for opportunities to increase mobility, communication, security, and economic prosperity, multiple speakers said.

U.S. clean energy projects are on hold due to bottlenecks in the process for permitting new transmission lines and grid interconnections. The queue of projects waiting for approval by transmission operators would effectively triple the size of our generating resource, said Rajeev Ram , a professor of electrical engineering at MIT. Removing some of those logistical barriers through AI, modeling, and software tools can help accelerate the timeline for projects that could provide clean energy to the grid, said Ram.

Yi Cui , the director of Stanford’s Sustainability Accelerator , is one of the leading experts developing batteries for renewable energy storage. Scholars in the Stanford Doerr School of Sustainability – which celebrated its first anniversary in September – have embraced a core philosophy of thinking about scale at the beginning of the design process, which is a good sign, Cui said.

For example, the relative scarcity of some elements – such as lithium, cobalt, and nickel – in current battery designs could limit their potential for large-scale production at low cost. Cui emphasized that scientists could focus on designing battery materials based on more widely available minerals, like zinc, manganese, and iron .

“We need to figure out for each of these technologies what is already going on at the gigaton-scale – like natural cycles, like agriculture – and see what we can do to tweak it in the right way so that you can create a market and use market mechanisms to scale it,” said Arun Majumdar , the inaugural dean of the Stanford Doerr School of Sustainability.

Others highlighted the importance of driving down costs for companies and consumers. If innovators can eliminate the green premium – the cost of choosing a clean energy technology over a traditional source – for their products, they will be competitive in the market.

Meanwhile, incentives like subsidies for renewable energy will need to be supplemented with policies that actively discourage use of carbon-intensive resources. “If we’re serious about addressing climate change, we’ve got to have a price on carbon,” whether through direct pricing per ton or indirectly through regulation, said Majumdar.

Powered by electrons versus molecules

The grid is essentially a system of wires that transports electrons from power plants to consumers. However, grid electrification will only get us about halfway to reducing greenhouse gas emissions, noted Sally Benson , the Precourt Family Professor, who moderated one of the panels.

Eighty percent of global energy comes from fossil fuels. Much of this comes in the form of liquid fossil fuels for transportation – cars, planes, ships, and some trains. The challenges of developing batteries and grid storage capable of providing electricity without interruption could limit electrification of some parts of the transportation sector. Instead, renewable fuels like hydrogen, biofuels, and fuels made primarily from captured carbon dioxide may help reduce carbon emissions from heavy-duty transportation.

“Our challenge is to think that the future is electrification, but that doesn’t mean that electrons are going to do everything for us directly,” said Anthony Kovscek , the Keleen and Carlton Beal Professor in the Stanford Doerr School of Sustainability.

Hydrogen could help bridge the gap to carbon neutrality, said Eric Toone , managing director and technical lead at Breakthrough Energy Ventures.

“Hydrogen is pure, reactive chemical energy. If you have enough hydrogen, you can do anything,” he said.

Zara Summers is the chief science officer at LanzaTech, a company that makes chemicals and fuels from carbon dioxide captured from factories and other industrial sources.

LanzaTech has been working to develop ethanol alternatives that make use of carbon from municipal waste or industrial emissions. These alternatives could serve as effective drop-in replacements for liquid fuels like gasoline, with the added benefit of easy adoption by the public and ability to tap into existing supply chains, but many current economic incentives specifically benefit corn-based ethanol.

“If you’re going to go big, you have to be at cost parity or better. But, you also have to fight against policy that’s written with a solution in mind, not an outcome,” said Summers. She highlighted how designing policies that are flexible and adaptable to new innovations will help bring solutions to scale.

Science as the bedrock

In addition to the challenge of rapidly reducing greenhouse gas emissions, the forum also explored solutions for removing historic carbon emissions from the atmosphere. During a panel on greenhouse gas removal strategies , speakers turned the focus to more low-tech solutions: carbon cycles in nature. For example, Benson enthusiastically described enhanced weathering, which builds on a naturally occurring process where rain interacts with certain rocks to form a mild acid. This acid then reacts with carbon dioxide in the atmosphere to form solid compounds that permanently store carbon.

Chris Field , the director of the Stanford Woods Institute for the Environment , cited research published last month which found that adding crushed basalt rocks for enhanced weathering could increase productivity and soil health on croplands .

“It really highlights where you can potentially accomplish these big co-benefits that can make something that’s a real challenge logistically or financially come into the realm of possibility,” said Field.

The energy transition touches all of the major social-environmental systems. A final panel brought together experts on freshwater, oceans and aquatic foods, and agricultural technology to explore cultivating resilience amid climate pressures. “Agriculture sits at the very center of many of the pressures that we’re putting on Earth’s systems,” said Jim Leape , co-director of the Stanford Center for Ocean Solutions .

During a fireside chat, Majumdar discussed emerging trends in clean energy with Steven Chu , the William R. Kenan, Jr. Professor in the School of Humanities and Sciences . They mentioned the “low-hanging fruit” of energy efficiency, the future of nuclear fusion, and balancing the energy transition with national and economic security. Nevertheless, Chu brought the conversation back to the critical role of new inventions.

“As a physicist, when I stand back and look at things: What really changed the world? New materials are actually what changed the world,” said Chu, a former U.S. Secretary of Energy who embodies the impact of science-based decision-making in energy systems as the first scientist to hold a Cabinet position.

From the steam engine and the agricultural revolution to semiconductors and nuclear fission, leaps forward in technology have enabled global-scale changes and development. Highlighting the vision for the Stanford Doerr School of Sustainability, Majumdar noted that when research institutions like Stanford collaborate with public and private entities, they can serve as a place where scholars can serve as incubators for translating novel ideas into impact.

Climate change is a long-lasting change in the weather arrays across tropics to polls. It is a global threat that has embarked on to put stress on various sectors. This study is aimed to conceptually engineer how climate variability is deteriorating the sustainability of diverse sectors worldwide. Specifically, the agricultural sector’s vulnerability is a globally concerning scenario, as sufficient production and food supplies are threatened due to irreversible weather fluctuations. In turn, it is challenging the global feeding patterns, particularly in countries with agriculture as an integral part of their economy and total productivity. Climate change has also put the integrity and survival of many species at stake due to shifts in optimum temperature ranges, thereby accelerating biodiversity loss by progressively changing the ecosystem structures. Climate variations increase the likelihood of particular food and waterborne and vector-borne diseases, and a recent example is a coronavirus pandemic. Climate change also accelerates the enigma of antimicrobial resistance, another threat to human health due to the increasing incidence of resistant pathogenic infections. Besides, the global tourism industry is devastated as climate change impacts unfavorable tourism spots. The methodology investigates hypothetical scenarios of climate variability and attempts to describe the quality of evidence to facilitate readers’ careful, critical engagement. Secondary data is used to identify sustainability issues such as environmental, social, and economic viability. To better understand the problem, gathered the information in this report from various media outlets, research agencies, policy papers, newspapers, and other sources. This review is a sectorial assessment of climate change mitigation and adaptation approaches worldwide in the aforementioned sectors and the associated economic costs. According to the findings, government involvement is necessary for the country’s long-term development through strict accountability of resources and regulations implemented in the past to generate cutting-edge climate policy. Therefore, mitigating the impacts of climate change must be of the utmost importance, and hence, this global threat requires global commitment to address its dreadful implications to ensure global sustenance.

Introduction

Worldwide observed and anticipated climatic changes for the twenty-first century and global warming are significant global changes that have been encountered during the past 65 years. Climate change (CC) is an inter-governmental complex challenge globally with its influence over various components of the ecological, environmental, socio-political, and socio-economic disciplines (Adger et al.  2005 ; Leal Filho et al.  2021 ; Feliciano et al.  2022 ). Climate change involves heightened temperatures across numerous worlds (Battisti and Naylor  2009 ; Schuurmans  2021 ; Weisheimer and Palmer  2005 ; Yadav et al.  2015 ). With the onset of the industrial revolution, the problem of earth climate was amplified manifold (Leppänen et al.  2014 ). It is reported that the immediate attention and due steps might increase the probability of overcoming its devastating impacts. It is not plausible to interpret the exact consequences of climate change (CC) on a sectoral basis (Izaguirre et al.  2021 ; Jurgilevich et al.  2017 ), which is evident by the emerging level of recognition plus the inclusion of climatic uncertainties at both local and national level of policymaking (Ayers et al.  2014 ).

Climate change is characterized based on the comprehensive long-haul temperature and precipitation trends and other components such as pressure and humidity level in the surrounding environment. Besides, the irregular weather patterns, retreating of global ice sheets, and the corresponding elevated sea level rise are among the most renowned international and domestic effects of climate change (Lipczynska-Kochany  2018 ; Michel et al.  2021 ; Murshed and Dao 2020 ). Before the industrial revolution, natural sources, including volcanoes, forest fires, and seismic activities, were regarded as the distinct sources of greenhouse gases (GHGs) such as CO 2 , CH 4 , N 2 O, and H 2 O into the atmosphere (Murshed et al. 2020 ; Hussain et al.  2020 ; Sovacool et al.  2021 ; Usman and Balsalobre-Lorente 2022 ; Murshed 2022 ). United Nations Framework Convention on Climate Change (UNFCCC) struck a major agreement to tackle climate change and accelerate and intensify the actions and investments required for a sustainable low-carbon future at Conference of the Parties (COP-21) in Paris on December 12, 2015. The Paris Agreement expands on the Convention by bringing all nations together for the first time in a single cause to undertake ambitious measures to prevent climate change and adapt to its impacts, with increased funding to assist developing countries in doing so. As so, it marks a turning point in the global climate fight. The core goal of the Paris Agreement is to improve the global response to the threat of climate change by keeping the global temperature rise this century well below 2 °C over pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5° C (Sharma et al. 2020 ; Sharif et al. 2020 ; Chien et al. 2021 .

Furthermore, the agreement aspires to strengthen nations’ ability to deal with the effects of climate change and align financing flows with low GHG emissions and climate-resilient paths (Shahbaz et al. 2019 ; Anwar et al. 2021 ; Usman et al. 2022a ). To achieve these lofty goals, adequate financial resources must be mobilized and provided, as well as a new technology framework and expanded capacity building, allowing developing countries and the most vulnerable countries to act under their respective national objectives. The agreement also establishes a more transparent action and support mechanism. All Parties are required by the Paris Agreement to do their best through “nationally determined contributions” (NDCs) and to strengthen these efforts in the coming years (Balsalobre-Lorente et al. 2020 ). It includes obligations that all Parties regularly report on their emissions and implementation activities. A global stock-take will be conducted every five years to review collective progress toward the agreement’s goal and inform the Parties’ future individual actions. The Paris Agreement became available for signature on April 22, 2016, Earth Day, at the United Nations Headquarters in New York. On November 4, 2016, it went into effect 30 days after the so-called double threshold was met (ratification by 55 nations accounting for at least 55% of world emissions). More countries have ratified and continue to ratify the agreement since then, bringing 125 Parties in early 2017. To fully operationalize the Paris Agreement, a work program was initiated in Paris to define mechanisms, processes, and recommendations on a wide range of concerns (Murshed et al. 2021 ). Since 2016, Parties have collaborated in subsidiary bodies (APA, SBSTA, and SBI) and numerous formed entities. The Conference of the Parties functioning as the meeting of the Parties to the Paris Agreement (CMA) convened for the first time in November 2016 in Marrakesh in conjunction with COP22 and made its first two resolutions. The work plan is scheduled to be finished by 2018. Some mitigation and adaptation strategies to reduce the emission in the prospective of Paris agreement are following firstly, a long-term goal of keeping the increase in global average temperature to well below 2 °C above pre-industrial levels, secondly, to aim to limit the rise to 1.5 °C, since this would significantly reduce risks and the impacts of climate change, thirdly, on the need for global emissions to peak as soon as possible, recognizing that this will take longer for developing countries, lastly, to undertake rapid reductions after that under the best available science, to achieve a balance between emissions and removals in the second half of the century. On the other side, some adaptation strategies are; strengthening societies’ ability to deal with the effects of climate change and to continue & expand international assistance for developing nations’ adaptation.

However, anthropogenic activities are currently regarded as most accountable for CC (Murshed et al. 2022 ). Apart from the industrial revolution, other anthropogenic activities include excessive agricultural operations, which further involve the high use of fuel-based mechanization, burning of agricultural residues, burning fossil fuels, deforestation, national and domestic transportation sectors, etc. (Huang et al.  2016 ). Consequently, these anthropogenic activities lead to climatic catastrophes, damaging local and global infrastructure, human health, and total productivity. Energy consumption has mounted GHGs levels concerning warming temperatures as most of the energy production in developing countries comes from fossil fuels (Balsalobre-Lorente et al. 2022 ; Usman et al. 2022b ; Abbass et al. 2021a ; Ishikawa-Ishiwata and Furuya  2022 ).

This review aims to highlight the effects of climate change in a socio-scientific aspect by analyzing the existing literature on various sectorial pieces of evidence globally that influence the environment. Although this review provides a thorough examination of climate change and its severe affected sectors that pose a grave danger for global agriculture, biodiversity, health, economy, forestry, and tourism, and to purpose some practical prophylactic measures and mitigation strategies to be adapted as sound substitutes to survive from climate change (CC) impacts. The societal implications of irregular weather patterns and other effects of climate changes are discussed in detail. Some numerous sustainable mitigation measures and adaptation practices and techniques at the global level are discussed in this review with an in-depth focus on its economic, social, and environmental aspects. Methods of data collection section are included in the supplementary information.

Related study and its objectives.

Today, we live an ordinary life in the beautiful digital, globalized world where climate change has a decisive role. What happens in one country has a massive influence on geographically far apart countries, which points to the current crisis known as COVID-19 (Sarkar et al.  2021 ). The most dangerous disease like COVID-19 has affected the world’s climate changes and economic conditions (Abbass et al. 2022 ; Pirasteh-Anosheh et al.  2021 ). The purpose of the present study is to review the status of research on the subject, which is based on “Global Climate Change Impacts, adaptation, and sustainable mitigation measures” by systematically reviewing past published and unpublished research work. Furthermore, the current study seeks to comment on research on the same topic and suggest future research on the same topic. Specifically, the present study aims: The first one is, organize publications to make them easy and quick to find. Secondly, to explore issues in this area, propose an outline of research for future work. The third aim of the study is to synthesize the previous literature on climate change, various sectors, and their mitigation measurement. Lastly , classify the articles according to the different methods and procedures that have been adopted.

Review methodology for reviewers

This review-based article followed systematic literature review techniques that have proved the literature review as a rigorous framework (Benita  2021 ; Tranfield et al.  2003 ). Moreover, we illustrate in Fig.  1 the search method that we have started for this research. First, finalized the research theme to search literature (Cooper et al.  2018 ). Second, used numerous research databases to search related articles and download from the database (Web of Science, Google Scholar, Scopus Index Journals, Emerald, Elsevier Science Direct, Springer, and Sciverse). We focused on various articles, with research articles, feedback pieces, short notes, debates, and review articles published in scholarly journals. Reports used to search for multiple keywords such as “Climate Change,” “Mitigation and Adaptation,” “Department of Agriculture and Human Health,” “Department of Biodiversity and Forestry,” etc.; in summary, keyword list and full text have been made. Initially, the search for keywords yielded a large amount of literature.

Methodology search for finalized articles for investigations.

Since 2020, it has been impossible to review all the articles found; some restrictions have been set for the literature exhibition. The study searched 95 articles on a different database mentioned above based on the nature of the study. It excluded 40 irrelevant papers due to copied from a previous search after readings tiles, abstract and full pieces. The criteria for inclusion were: (i) articles focused on “Global Climate Change Impacts, adaptation, and sustainable mitigation measures,” and (ii) the search key terms related to study requirements. The complete procedure yielded 55 articles for our study. We repeat our search on the “Web of Science and Google Scholars” database to enhance the search results and check the referenced articles.

In this study, 55 articles are reviewed systematically and analyzed for research topics and other aspects, such as the methods, contexts, and theories used in these studies. Furthermore, this study analyzes closely related areas to provide unique research opportunities in the future. The study also discussed future direction opportunities and research questions by understanding the research findings climate changes and other affected sectors. The reviewed paper framework analysis process is outlined in Fig.  2 .

Framework of the analysis Process.

Natural disasters and climate change’s socio-economic consequences

Natural and environmental disasters can be highly variable from year to year; some years pass with very few deaths before a significant disaster event claims many lives (Symanski et al.  2021 ). Approximately 60,000 people globally died from natural disasters each year on average over the past decade (Ritchie and Roser  2014 ; Wiranata and Simbolon  2021 ). So, according to the report, around 0.1% of global deaths. Annual variability in the number and share of deaths from natural disasters in recent decades are shown in Fig.  3 . The number of fatalities can be meager—sometimes less than 10,000, and as few as 0.01% of all deaths. But shock events have a devastating impact: the 1983–1985 famine and drought in Ethiopia; the 2004 Indian Ocean earthquake and tsunami; Cyclone Nargis, which struck Myanmar in 2008; and the 2010 Port-au-Prince earthquake in Haiti and now recent example is COVID-19 pandemic (Erman et al.  2021 ). These events pushed global disaster deaths to over 200,000—more than 0.4% of deaths in these years. Low-frequency, high-impact events such as earthquakes and tsunamis are not preventable, but such high losses of human life are. Historical evidence shows that earlier disaster detection, more robust infrastructure, emergency preparedness, and response programmers have substantially reduced disaster deaths worldwide. Low-income is also the most vulnerable to disasters; improving living conditions, facilities, and response services in these areas would be critical in reducing natural disaster deaths in the coming decades.

The interior regions of the continent are likely to be impacted by rising temperatures (Dimri et al.  2018 ; Goes et al.  2020 ; Mannig et al.  2018 ; Schuurmans  2021 ). Weather patterns change due to the shortage of natural resources (water), increase in glacier melting, and rising mercury are likely to cause extinction to many planted species (Gampe et al.  2016 ; Mihiretu et al.  2021 ; Shaffril et al.  2018 ).On the other hand, the coastal ecosystem is on the verge of devastation (Perera et al.  2018 ; Phillips  2018 ). The temperature rises, insect disease outbreaks, health-related problems, and seasonal and lifestyle changes are persistent, with a strong probability of these patterns continuing in the future (Abbass et al. 2021c ; Hussain et al.  2018 ). At the global level, a shortage of good infrastructure and insufficient adaptive capacity are hammering the most (IPCC  2013 ). In addition to the above concerns, a lack of environmental education and knowledge, outdated consumer behavior, a scarcity of incentives, a lack of legislation, and the government’s lack of commitment to climate change contribute to the general public’s concerns. By 2050, a 2 to 3% rise in mercury and a drastic shift in rainfall patterns may have serious consequences (Huang et al. 2022 ; Gorst et al.  2018 ). Natural and environmental calamities caused huge losses globally, such as decreased agriculture outputs, rehabilitation of the system, and rebuilding necessary technologies (Ali and Erenstein  2017 ; Ramankutty et al.  2018 ; Yu et al.  2021 ) (Table ​ (Table1). 1 ). Furthermore, in the last 3 or 4 years, the world has been plagued by smog-related eye and skin diseases, as well as a rise in road accidents due to poor visibility.

Climate change and agriculture

Global agriculture is the ultimate sector responsible for 30–40% of all greenhouse emissions, which makes it a leading industry predominantly contributing to climate warming and significantly impacted by it (Grieg; Mishra et al.  2021 ; Ortiz et al.  2021 ; Thornton and Lipper  2014 ). Numerous agro-environmental and climatic factors that have a dominant influence on agriculture productivity (Pautasso et al.  2012 ) are significantly impacted in response to precipitation extremes including floods, forest fires, and droughts (Huang  2004 ). Besides, the immense dependency on exhaustible resources also fuels the fire and leads global agriculture to become prone to devastation. Godfray et al. ( 2010 ) mentioned that decline in agriculture challenges the farmer’s quality of life and thus a significant factor to poverty as the food and water supplies are critically impacted by CC (Ortiz et al.  2021 ; Rosenzweig et al.  2014 ). As an essential part of the economic systems, especially in developing countries, agricultural systems affect the overall economy and potentially the well-being of households (Schlenker and Roberts  2009 ). According to the report published by the Intergovernmental Panel on Climate Change (IPCC), atmospheric concentrations of greenhouse gases, i.e., CH 4, CO 2 , and N 2 O, are increased in the air to extraordinary levels over the last few centuries (Usman and Makhdum 2021 ; Stocker et al.  2013 ). Climate change is the composite outcome of two different factors. The first is the natural causes, and the second is the anthropogenic actions (Karami 2012 ). It is also forecasted that the world may experience a typical rise in temperature stretching from 1 to 3.7 °C at the end of this century (Pachauri et al. 2014 ). The world’s crop production is also highly vulnerable to these global temperature-changing trends as raised temperatures will pose severe negative impacts on crop growth (Reidsma et al. 2009 ). Some of the recent modeling about the fate of global agriculture is briefly described below.

Decline in cereal productivity

Crop productivity will also be affected dramatically in the next few decades due to variations in integral abiotic factors such as temperature, solar radiation, precipitation, and CO 2 . These all factors are included in various regulatory instruments like progress and growth, weather-tempted changes, pest invasions (Cammell and Knight 1992 ), accompanying disease snags (Fand et al. 2012 ), water supplies (Panda et al. 2003 ), high prices of agro-products in world’s agriculture industry, and preeminent quantity of fertilizer consumption. Lobell and field ( 2007 ) claimed that from 1962 to 2002, wheat crop output had condensed significantly due to rising temperatures. Therefore, during 1980–2011, the common wheat productivity trends endorsed extreme temperature events confirmed by Gourdji et al. ( 2013 ) around South Asia, South America, and Central Asia. Various other studies (Asseng, Cao, Zhang, and Ludwig 2009 ; Asseng et al. 2013 ; García et al. 2015 ; Ortiz et al. 2021 ) also proved that wheat output is negatively affected by the rising temperatures and also caused adverse effects on biomass productivity (Calderini et al. 1999 ; Sadras and Slafer 2012 ). Hereafter, the rice crop is also influenced by the high temperatures at night. These difficulties will worsen because the temperature will be rising further in the future owing to CC (Tebaldi et al. 2006 ). Another research conducted in China revealed that a 4.6% of rice production per 1 °C has happened connected with the advancement in night temperatures (Tao et al. 2006 ). Moreover, the average night temperature growth also affected rice indicia cultivar’s output pragmatically during 25 years in the Philippines (Peng et al. 2004 ). It is anticipated that the increase in world average temperature will also cause a substantial reduction in yield (Hatfield et al. 2011 ; Lobell and Gourdji 2012 ). In the southern hemisphere, Parry et al. ( 2007 ) noted a rise of 1–4 °C in average daily temperatures at the end of spring season unti the middle of summers, and this raised temperature reduced crop output by cutting down the time length for phenophases eventually reduce the yield (Hatfield and Prueger 2015 ; R. Ortiz 2008 ). Also, world climate models have recommended that humid and subtropical regions expect to be plentiful prey to the upcoming heat strokes (Battisti and Naylor 2009 ). Grain production is the amalgamation of two constituents: the average weight and the grain output/m 2 , however, in crop production. Crop output is mainly accredited to the grain quantity (Araus et al. 2008 ; Gambín and Borrás 2010 ). In the times of grain set, yield resources are mainly strewn between hitherto defined components, i.e., grain usual weight and grain output, which presents a trade-off between them (Gambín and Borrás 2010 ) beside disparities in per grain integration (B. L. Gambín et al. 2006 ). In addition to this, the maize crop is also susceptible to raised temperatures, principally in the flowering stage (Edreira and Otegui 2013 ). In reality, the lower grain number is associated with insufficient acclimatization due to intense photosynthesis and higher respiration and the high-temperature effect on the reproduction phenomena (Edreira and Otegui 2013 ). During the flowering phase, maize visible to heat (30–36 °C) seemed less anthesis-silking intermissions (Edreira et al. 2011 ). Another research by Dupuis and Dumas ( 1990 ) proved that a drop in spikelet when directly visible to high temperatures above 35 °C in vitro pollination. Abnormalities in kernel number claimed by Vega et al. ( 2001 ) is related to conceded plant development during a flowering phase that is linked with the active ear growth phase and categorized as a critical phase for approximation of kernel number during silking (Otegui and Bonhomme 1998 ).

The retort of rice output to high temperature presents disparities in flowering patterns, and seed set lessens and lessens grain weight (Qasim et al. 2020 ; Qasim, Hammad, Maqsood, Tariq, & Chawla). During the daytime, heat directly impacts flowers which lessens the thesis period and quickens the earlier peak flowering (Tao et al. 2006 ). Antagonistic effect of higher daytime temperature d on pollen sprouting proposed seed set decay, whereas, seed set was lengthily reduced than could be explicated by pollen growing at high temperatures 40◦C (Matsui et al. 2001 ).

The decline in wheat output is linked with higher temperatures, confirmed in numerous studies (Semenov 2009 ; Stone and Nicolas 1994 ). High temperatures fast-track the arrangements of plant expansion (Blum et al. 2001 ), diminution photosynthetic process (Salvucci and Crafts‐Brandner 2004 ), and also considerably affect the reproductive operations (Farooq et al. 2011 ).

The destructive impacts of CC induced weather extremes to deteriorate the integrity of crops (Chaudhary et al. 2011 ), e.g., Spartan cold and extreme fog cause falling and discoloration of betel leaves (Rosenzweig et al. 2001 ), giving them a somehow reddish appearance, squeezing of lemon leaves (Pautasso et al. 2012 ), as well as root rot of pineapple, have reported (Vedwan and Rhoades 2001 ). Henceforth, in tackling the disruptive effects of CC, several short-term and long-term management approaches are the crucial need of time (Fig.  4 ). Moreover, various studies (Chaudhary et al. 2011 ; Patz et al. 2005 ; Pautasso et al. 2012 ) have demonstrated adapting trends such as ameliorating crop diversity can yield better adaptability towards CC.

Schematic description of potential impacts of climate change on the agriculture sector and the appropriate mitigation and adaptation measures to overcome its impact.

Climate change impacts on biodiversity

Global biodiversity is among the severe victims of CC because it is the fastest emerging cause of species loss. Studies demonstrated that the massive scale species dynamics are considerably associated with diverse climatic events (Abraham and Chain 1988 ; Manes et al. 2021 ; A. M. D. Ortiz et al. 2021 ). Both the pace and magnitude of CC are altering the compatible habitat ranges for living entities of marine, freshwater, and terrestrial regions. Alterations in general climate regimes influence the integrity of ecosystems in numerous ways, such as variation in the relative abundance of species, range shifts, changes in activity timing, and microhabitat use (Bates et al. 2014 ). The geographic distribution of any species often depends upon its ability to tolerate environmental stresses, biological interactions, and dispersal constraints. Hence, instead of the CC, the local species must only accept, adapt, move, or face extinction (Berg et al. 2010 ). So, the best performer species have a better survival capacity for adjusting to new ecosystems or a decreased perseverance to survive where they are already situated (Bates et al. 2014 ). An important aspect here is the inadequate habitat connectivity and access to microclimates, also crucial in raising the exposure to climate warming and extreme heatwave episodes. For example, the carbon sequestration rates are undergoing fluctuations due to climate-driven expansion in the range of global mangroves (Cavanaugh et al. 2014 ).

Similarly, the loss of kelp-forest ecosystems in various regions and its occupancy by the seaweed turfs has set the track for elevated herbivory by the high influx of tropical fish populations. Not only this, the increased water temperatures have exacerbated the conditions far away from the physiological tolerance level of the kelp communities (Vergés et al. 2016 ; Wernberg et al. 2016 ). Another pertinent danger is the devastation of keystone species, which even has more pervasive effects on the entire communities in that habitat (Zarnetske et al. 2012 ). It is particularly important as CC does not specify specific populations or communities. Eventually, this CC-induced redistribution of species may deteriorate carbon storage and the net ecosystem productivity (Weed et al. 2013 ). Among the typical disruptions, the prominent ones include impacts on marine and terrestrial productivity, marine community assembly, and the extended invasion of toxic cyanobacteria bloom (Fossheim et al. 2015 ).

The CC-impacted species extinction is widely reported in the literature (Beesley et al. 2019 ; Urban 2015 ), and the predictions of demise until the twenty-first century are dreadful (Abbass et al. 2019 ; Pereira et al. 2013 ). In a few cases, northward shifting of species may not be formidable as it allows mountain-dwelling species to find optimum climates. However, the migrant species may be trapped in isolated and incompatible habitats due to losing topography and range (Dullinger et al. 2012 ). For example, a study indicated that the American pika has been extirpated or intensely diminished in some regions, primarily attributed to the CC-impacted extinction or at least local extirpation (Stewart et al. 2015 ). Besides, the anticipation of persistent responses to the impacts of CC often requires data records of several decades to rigorously analyze the critical pre and post CC patterns at species and ecosystem levels (Manes et al. 2021 ; Testa et al. 2018 ).

Nonetheless, the availability of such long-term data records is rare; hence, attempts are needed to focus on these profound aspects. Biodiversity is also vulnerable to the other associated impacts of CC, such as rising temperatures, droughts, and certain invasive pest species. For instance, a study revealed the changes in the composition of plankton communities attributed to rising temperatures. Henceforth, alterations in such aquatic producer communities, i.e., diatoms and calcareous plants, can ultimately lead to variation in the recycling of biological carbon. Moreover, such changes are characterized as a potential contributor to CO 2 differences between the Pleistocene glacial and interglacial periods (Kohfeld et al. 2005 ).

Climate change implications on human health

It is an understood corporality that human health is a significant victim of CC (Costello et al. 2009 ). According to the WHO, CC might be responsible for 250,000 additional deaths per year during 2030–2050 (Watts et al. 2015 ). These deaths are attributed to extreme weather-induced mortality and morbidity and the global expansion of vector-borne diseases (Lemery et al. 2021; Yang and Usman 2021 ; Meierrieks 2021 ; UNEP 2017 ). Here, some of the emerging health issues pertinent to this global problem are briefly described.

Climate change and antimicrobial resistance with corresponding economic costs

Antimicrobial resistance (AMR) is an up-surging complex global health challenge (Garner et al. 2019 ; Lemery et al. 2021 ). Health professionals across the globe are extremely worried due to this phenomenon that has critical potential to reverse almost all the progress that has been achieved so far in the health discipline (Gosling and Arnell 2016 ). A massive amount of antibiotics is produced by many pharmaceutical industries worldwide, and the pathogenic microorganisms are gradually developing resistance to them, which can be comprehended how strongly this aspect can shake the foundations of national and global economies (UNEP 2017 ). This statement is supported by the fact that AMR is not developing in a particular region or country. Instead, it is flourishing in every continent of the world (WHO 2018 ). This plague is heavily pushing humanity to the post-antibiotic era, in which currently antibiotic-susceptible pathogens will once again lead to certain endemics and pandemics after being resistant(WHO 2018 ). Undesirably, if this statement would become a factuality, there might emerge certain risks in undertaking sophisticated interventions such as chemotherapy, joint replacement cases, and organ transplantation (Su et al. 2018 ). Presently, the amplification of drug resistance cases has made common illnesses like pneumonia, post-surgical infections, HIV/AIDS, tuberculosis, malaria, etc., too difficult and costly to be treated or cure well (WHO 2018 ). From a simple example, it can be assumed how easily antibiotic-resistant strains can be transmitted from one person to another and ultimately travel across the boundaries (Berendonk et al. 2015 ). Talking about the second- and third-generation classes of antibiotics, e.g., most renowned generations of cephalosporin antibiotics that are more expensive, broad-spectrum, more toxic, and usually require more extended periods whenever prescribed to patients (Lemery et al. 2021 ; Pärnänen et al. 2019 ). This scenario has also revealed that the abundance of resistant strains of pathogens was also higher in the Southern part (WHO 2018 ). As southern parts are generally warmer than their counterparts, it is evident from this example how CC-induced global warming can augment the spread of antibiotic-resistant strains within the biosphere, eventually putting additional economic burden in the face of developing new and costlier antibiotics. The ARG exchange to susceptible bacteria through one of the potential mechanisms, transformation, transduction, and conjugation; Selection pressure can be caused by certain antibiotics, metals or pesticides, etc., as shown in Fig.  5 .

Certain studies highlighted that conventional urban wastewater treatment plants are typical hotspots where most bacterial strains exchange genetic material through horizontal gene transfer (Fig.  5 ). Although at present, the extent of risks associated with the antibiotic resistance found in wastewater is complicated; environmental scientists and engineers have particular concerns about the potential impacts of these antibiotic resistance genes on human health (Ashbolt 2015 ). At most undesirable and worst case, these antibiotic-resistant genes containing bacteria can make their way to enter into the environment (Pruden et al. 2013 ), irrigation water used for crops and public water supplies and ultimately become a part of food chains and food webs (Ma et al. 2019 ; D. Wu et al. 2019 ). This problem has been reported manifold in several countries (Hendriksen et al. 2019 ), where wastewater as a means of irrigated water is quite common.

Climate change and vector borne-diseases

Temperature is a fundamental factor for the sustenance of living entities regardless of an ecosystem. So, a specific living being, especially a pathogen, requires a sophisticated temperature range to exist on earth. The second essential component of CC is precipitation, which also impacts numerous infectious agents’ transport and dissemination patterns. Global rising temperature is a significant cause of many species extinction. On the one hand, this changing environmental temperature may be causing species extinction, and on the other, this warming temperature might favor the thriving of some new organisms. Here, it was evident that some pathogens may also upraise once non-evident or reported (Patz et al. 2000 ). This concept can be exemplified through certain pathogenic strains of microorganisms that how the likelihood of various diseases increases in response to climate warming-induced environmental changes (Table ​ (Table2 2 ).

Examples of how various environmental changes affect various infectious diseases in humans

Source: Aron and Patz ( 2001 )

A recent example is an outburst of coronavirus (COVID-19) in the Republic of China, causing pneumonia and severe acute respiratory complications (Cui et al. 2021 ; Song et al. 2021 ). The large family of viruses is harbored in numerous animals, bats, and snakes in particular (livescience.com) with the subsequent transfer into human beings. Hence, it is worth noting that the thriving of numerous vectors involved in spreading various diseases is influenced by Climate change (Ogden 2018 ; Santos et al. 2021 ).

Psychological impacts of climate change

Climate change (CC) is responsible for the rapid dissemination and exaggeration of certain epidemics and pandemics. In addition to the vast apparent impacts of climate change on health, forestry, agriculture, etc., it may also have psychological implications on vulnerable societies. It can be exemplified through the recent outburst of (COVID-19) in various countries around the world (Pal 2021 ). Besides, the victims of this viral infection have made healthy beings scarier and terrified. In the wake of such epidemics, people with common colds or fever are also frightened and must pass specific regulatory protocols. Living in such situations continuously terrifies the public and makes the stress familiar, which eventually makes them psychologically weak (npr.org).

CC boosts the extent of anxiety, distress, and other issues in public, pushing them to develop various mental-related problems. Besides, frequent exposure to extreme climatic catastrophes such as geological disasters also imprints post-traumatic disorder, and their ubiquitous occurrence paves the way to developing chronic psychological dysfunction. Moreover, repetitive listening from media also causes an increase in the person’s stress level (Association 2020 ). Similarly, communities living in flood-prone areas constantly live in extreme fear of drowning and die by floods. In addition to human lives, the flood-induced destruction of physical infrastructure is a specific reason for putting pressure on these communities (Ogden 2018 ). For instance, Ogden ( 2018 ) comprehensively denoted that Katrina’s Hurricane augmented the mental health issues in the victim communities.

Climate change impacts on the forestry sector

Forests are the global regulators of the world’s climate (FAO 2018 ) and have an indispensable role in regulating global carbon and nitrogen cycles (Rehman et al. 2021 ; Reichstein and Carvalhais 2019 ). Hence, disturbances in forest ecology affect the micro and macro-climates (Ellison et al. 2017 ). Climate warming, in return, has profound impacts on the growth and productivity of transboundary forests by influencing the temperature and precipitation patterns, etc. As CC induces specific changes in the typical structure and functions of ecosystems (Zhang et al. 2017 ) as well impacts forest health, climate change also has several devastating consequences such as forest fires, droughts, pest outbreaks (EPA 2018 ), and last but not the least is the livelihoods of forest-dependent communities. The rising frequency and intensity of another CC product, i.e., droughts, pose plenty of challenges to the well-being of global forests (Diffenbaugh et al. 2017 ), which is further projected to increase soon (Hartmann et al. 2018 ; Lehner et al. 2017 ; Rehman et al. 2021 ). Hence, CC induces storms, with more significant impacts also put extra pressure on the survival of the global forests (Martínez-Alvarado et al. 2018 ), significantly since their influences are augmented during higher winter precipitations with corresponding wetter soils causing weak root anchorage of trees (Brázdil et al. 2018 ). Surging temperature regimes causes alterations in usual precipitation patterns, which is a significant hurdle for the survival of temperate forests (Allen et al. 2010 ; Flannigan et al. 2013 ), letting them encounter severe stress and disturbances which adversely affects the local tree species (Hubbart et al. 2016 ; Millar and Stephenson 2015 ; Rehman et al. 2021 ).

Climate change impacts on forest-dependent communities

Forests are the fundamental livelihood resource for about 1.6 billion people worldwide; out of them, 350 million are distinguished with relatively higher reliance (Bank 2008 ). Agro-forestry-dependent communities comprise 1.2 billion, and 60 million indigenous people solely rely on forests and their products to sustain their lives (Sunderlin et al. 2005 ). For example, in the entire African continent, more than 2/3rd of inhabitants depend on forest resources and woodlands for their alimonies, e.g., food, fuelwood and grazing (Wasiq and Ahmad 2004 ). The livings of these people are more intensely affected by the climatic disruptions making their lives harder (Brown et al. 2014 ). On the one hand, forest communities are incredibly vulnerable to CC due to their livelihoods, cultural and spiritual ties as well as socio-ecological connections, and on the other, they are not familiar with the term “climate change.” (Rahman and Alam 2016 ). Among the destructive impacts of temperature and rainfall, disruption of the agroforestry crops with resultant downscale growth and yield (Macchi et al. 2008 ). Cruz ( 2015 ) ascribed that forest-dependent smallholder farmers in the Philippines face the enigma of delayed fruiting, more severe damages by insect and pest incidences due to unfavorable temperature regimes, and changed rainfall patterns.

Among these series of challenges to forest communities, their well-being is also distinctly vulnerable to CC. Though the detailed climate change impacts on human health have been comprehensively mentioned in the previous section, some studies have listed a few more devastating effects on the prosperity of forest-dependent communities. For instance, the Himalayan people have been experiencing frequent skin-borne diseases such as malaria and other skin diseases due to increasing mosquitoes, wild boar as well, and new wasps species, particularly in higher altitudes that were almost non-existent before last 5–10 years (Xu et al. 2008 ). Similarly, people living at high altitudes in Bangladesh have experienced frequent mosquito-borne calamities (Fardous; Sharma 2012 ). In addition, the pace of other waterborne diseases such as infectious diarrhea, cholera, pathogenic induced abdominal complications and dengue has also been boosted in other distinguished regions of Bangladesh (Cell 2009 ; Gunter et al. 2008 ).

Upscaling hotter climate may positively affect the mobile organisms with shorter generation times because they can scurry from harsh conditions than the immobile species (Fettig et al. 2013 ; Schoene and Bernier 2012 ) and are also relatively more capable of adapting to new environments (Jactel et al. 2019 ). It reveals that insects adapt quickly to global warming due to their mobility advantages. Due to past outbreaks, the trees (forests) are relatively more susceptible victims (Kurz et al. 2008 ). Before CC, the influence of factors mentioned earlier, i.e., droughts and storms, was existent and made the forests susceptible to insect pest interventions; however, the global forests remain steadfast, assiduous, and green (Jactel et al. 2019 ). The typical reasons could be the insect herbivores were regulated by several tree defenses and pressures of predation (Wilkinson and Sherratt 2016 ). As climate greatly influences these phenomena, the global forests cannot be so sedulous against such challenges (Jactel et al. 2019 ). Table ​ Table3 3 demonstrates some of the particular considerations with practical examples that are essential while mitigating the impacts of CC in the forestry sector.

Essential considerations while mitigating the climate change impacts on the forestry sector

Climate change impacts on tourism

Tourism is a commercial activity that has roots in multi-dimensions and an efficient tool with adequate job generation potential, revenue creation, earning of spectacular foreign exchange, enhancement in cross-cultural promulgation and cooperation, a business tool for entrepreneurs and eventually for the country’s national development (Arshad et al. 2018 ; Scott 2021 ). Among a plethora of other disciplines, the tourism industry is also a distinct victim of climate warming (Gössling et al. 2012 ; Hall et al. 2015 ) as the climate is among the essential resources that enable tourism in particular regions as most preferred locations. Different places at different times of the year attract tourists both within and across the countries depending upon the feasibility and compatibility of particular weather patterns. Hence, the massive variations in these weather patterns resulting from CC will eventually lead to monumental challenges to the local economy in that specific area’s particular and national economy (Bujosa et al. 2015 ). For instance, the Intergovernmental Panel on Climate Change (IPCC) report demonstrated that the global tourism industry had faced a considerable decline in the duration of ski season, including the loss of some ski areas and the dramatic shifts in tourist destinations’ climate warming.

Furthermore, different studies (Neuvonen et al. 2015 ; Scott et al. 2004 ) indicated that various currently perfect tourist spots, e.g., coastal areas, splendid islands, and ski resorts, will suffer consequences of CC. It is also worth noting that the quality and potential of administrative management potential to cope with the influence of CC on the tourism industry is of crucial significance, which renders specific strengths of resiliency to numerous destinations to withstand against it (Füssel and Hildén 2014 ). Similarly, in the partial or complete absence of adequate socio-economic and socio-political capital, the high-demanding tourist sites scurry towards the verge of vulnerability. The susceptibility of tourism is based on different components such as the extent of exposure, sensitivity, life-supporting sectors, and capacity assessment factors (Füssel and Hildén 2014 ). It is obvious corporality that sectors such as health, food, ecosystems, human habitat, infrastructure, water availability, and the accessibility of a particular region are prone to CC. Henceforth, the sensitivity of these critical sectors to CC and, in return, the adaptive measures are a hallmark in determining the composite vulnerability of climate warming (Ionescu et al. 2009 ).

Moreover, the dependence on imported food items, poor hygienic conditions, and inadequate health professionals are dominant aspects affecting the local terrestrial and aquatic biodiversity. Meanwhile, the greater dependency on ecosystem services and its products also makes a destination more fragile to become a prey of CC (Rizvi et al. 2015 ). Some significant non-climatic factors are important indicators of a particular ecosystem’s typical health and functioning, e.g., resource richness and abundance portray the picture of ecosystem stability. Similarly, the species abundance is also a productive tool that ensures that the ecosystem has a higher buffering capacity, which is terrific in terms of resiliency (Roscher et al. 2013 ).

Climate change impacts on the economic sector

Climate plays a significant role in overall productivity and economic growth. Due to its increasingly global existence and its effect on economic growth, CC has become one of the major concerns of both local and international environmental policymakers (Ferreira et al. 2020 ; Gleditsch 2021 ; Abbass et al. 2021b ; Lamperti et al. 2021 ). The adverse effects of CC on the overall productivity factor of the agricultural sector are therefore significant for understanding the creation of local adaptation policies and the composition of productive climate policy contracts. Previous studies on CC in the world have already forecasted its effects on the agricultural sector. Researchers have found that global CC will impact the agricultural sector in different world regions. The study of the impacts of CC on various agrarian activities in other demographic areas and the development of relative strategies to respond to effects has become a focal point for researchers (Chandioet al. 2020 ; Gleditsch 2021 ; Mosavi et al. 2020 ).

With the rapid growth of global warming since the 1980s, the temperature has started increasing globally, which resulted in the incredible transformation of rain and evaporation in the countries. The agricultural development of many countries has been reliant, delicate, and susceptible to CC for a long time, and it is on the development of agriculture total factor productivity (ATFP) influence different crops and yields of farmers (Alhassan 2021 ; Wu  2020 ).

Food security and natural disasters are increasing rapidly in the world. Several major climatic/natural disasters have impacted local crop production in the countries concerned. The effects of these natural disasters have been poorly controlled by the development of the economies and populations and may affect human life as well. One example is China, which is among the world’s most affected countries, vulnerable to natural disasters due to its large population, harsh environmental conditions, rapid CC, low environmental stability, and disaster power. According to the January 2016 statistical survey, China experienced an economic loss of 298.3 billion Yuan, and about 137 million Chinese people were severely affected by various natural disasters (Xie et al. 2018 ).

Mitigation and adaptation strategies of climate changes

Adaptation and mitigation are the crucial factors to address the response to CC (Jahanzad et al. 2020 ). Researchers define mitigation on climate changes, and on the other hand, adaptation directly impacts climate changes like floods. To some extent, mitigation reduces or moderates greenhouse gas emission, and it becomes a critical issue both economically and environmentally (Botzen et al. 2021 ; Jahanzad et al. 2020 ; Kongsager 2018 ; Smit et al. 2000 ; Vale et al. 2021 ; Usman et al. 2021 ; Verheyen 2005 ).

Researchers have deep concern about the adaptation and mitigation methodologies in sectoral and geographical contexts. Agriculture, industry, forestry, transport, and land use are the main sectors to adapt and mitigate policies(Kärkkäinen et al. 2020 ; Waheed et al. 2021 ). Adaptation and mitigation require particular concern both at the national and international levels. The world has faced a significant problem of climate change in the last decades, and adaptation to these effects is compulsory for economic and social development. To adapt and mitigate against CC, one should develop policies and strategies at the international level (Hussain et al. 2020 ). Figure  6 depicts the list of current studies on sectoral impacts of CC with adaptation and mitigation measures globally.

Sectoral impacts of climate change with adaptation and mitigation measures.

Conclusion and future perspectives

Specific socio-agricultural, socio-economic, and physical systems are the cornerstone of psychological well-being, and the alteration in these systems by CC will have disastrous impacts. Climate variability, alongside other anthropogenic and natural stressors, influences human and environmental health sustainability. Food security is another concerning scenario that may lead to compromised food quality, higher food prices, and inadequate food distribution systems. Global forests are challenged by different climatic factors such as storms, droughts, flash floods, and intense precipitation. On the other hand, their anthropogenic wiping is aggrandizing their existence. Undoubtedly, the vulnerability scale of the world’s regions differs; however, appropriate mitigation and adaptation measures can aid the decision-making bodies in developing effective policies to tackle its impacts. Presently, modern life on earth has tailored to consistent climatic patterns, and accordingly, adapting to such considerable variations is of paramount importance. Because the faster changes in climate will make it harder to survive and adjust, this globally-raising enigma calls for immediate attention at every scale ranging from elementary community level to international level. Still, much effort, research, and dedication are required, which is the most critical time. Some policy implications can help us to mitigate the consequences of climate change, especially the most affected sectors like the agriculture sector;

Warming might lengthen the season in frost-prone growing regions (temperate and arctic zones), allowing for longer-maturing seasonal cultivars with better yields (Pfadenhauer 2020 ; Bonacci 2019 ). Extending the planting season may allow additional crops each year; when warming leads to frequent warmer months highs over critical thresholds, a split season with a brief summer fallow may be conceivable for short-period crops such as wheat barley, cereals, and many other vegetable crops. The capacity to prolong the planting season in tropical and subtropical places where the harvest season is constrained by precipitation or agriculture farming occurs after the year may be more limited and dependent on how precipitation patterns vary (Wu et al. 2017 ).

The genetic component is comprehensive for many yields, but it is restricted like kiwi fruit for a few. Ali et al. ( 2017 ) investigated how new crops will react to climatic changes (also stated in Mall et al. 2017 ). Hot temperature, drought, insect resistance; salt tolerance; and overall crop production and product quality increases would all be advantageous (Akkari 2016 ). Genetic mapping and engineering can introduce a greater spectrum of features. The adoption of genetically altered cultivars has been slowed, particularly in the early forecasts owing to the complexity in ensuring features are expediently expressed throughout the entire plant, customer concerns, economic profitability, and regulatory impediments (Wirehn 2018 ; Davidson et al. 2016 ).

To get the full benefit of the CO 2 would certainly require additional nitrogen and other fertilizers. Nitrogen not consumed by the plants may be excreted into groundwater, discharged into water surface, or emitted from the land, soil nitrous oxide when large doses of fertilizer are sprayed. Increased nitrogen levels in groundwater sources have been related to human chronic illnesses and impact marine ecosystems. Cultivation, grain drying, and other field activities have all been examined in depth in the studies (Barua et al. 2018 ).

• The technological and socio-economic adaptation

The policy consequence of the causative conclusion is that as a source of alternative energy, biofuel production is one of the routes that explain oil price volatility separate from international macroeconomic factors. Even though biofuel production has just begun in a few sample nations, there is still a tremendous worldwide need for feedstock to satisfy industrial expansion in China and the USA, which explains the food price relationship to the global oil price. Essentially, oil-exporting countries may create incentives in their economies to increase food production. It may accomplish by giving farmers financing, seedlings, fertilizers, and farming equipment. Because of the declining global oil price and, as a result, their earnings from oil export, oil-producing nations may be unable to subsidize food imports even in the near term. As a result, these countries can boost the agricultural value chain for export. It may be accomplished through R&D and adding value to their food products to increase income by correcting exchange rate misalignment and adverse trade terms. These nations may also diversify their economies away from oil, as dependence on oil exports alone is no longer economically viable given the extreme volatility of global oil prices. Finally, resource-rich and oil-exporting countries can convert to non-food renewable energy sources such as solar, hydro, coal, wind, wave, and tidal energy. By doing so, both world food and oil supplies would be maintained rather than harmed.

IRENA’s modeling work shows that, if a comprehensive policy framework is in place, efforts toward decarbonizing the energy future will benefit economic activity, jobs (outweighing losses in the fossil fuel industry), and welfare. Countries with weak domestic supply chains and a large reliance on fossil fuel income, in particular, must undertake structural reforms to capitalize on the opportunities inherent in the energy transition. Governments continue to give major policy assistance to extract fossil fuels, including tax incentives, financing, direct infrastructure expenditures, exemptions from environmental regulations, and other measures. The majority of major oil and gas producing countries intend to increase output. Some countries intend to cut coal output, while others plan to maintain or expand it. While some nations are beginning to explore and execute policies aimed at a just and equitable transition away from fossil fuel production, these efforts have yet to impact major producing countries’ plans and goals. Verifiable and comparable data on fossil fuel output and assistance from governments and industries are critical to closing the production gap. Governments could increase openness by declaring their production intentions in their climate obligations under the Paris Agreement.

It is firmly believed that achieving the Paris Agreement commitments is doubtlful without undergoing renewable energy transition across the globe (Murshed 2020 ; Zhao et al. 2022 ). Policy instruments play the most important role in determining the degree of investment in renewable energy technology. This study examines the efficacy of various policy strategies in the renewable energy industry of multiple nations. Although its impact is more visible in established renewable energy markets, a renewable portfolio standard is also a useful policy instrument. The cost of producing renewable energy is still greater than other traditional energy sources. Furthermore, government incentives in the R&D sector can foster innovation in this field, resulting in cost reductions in the renewable energy industry. These nations may export their technologies and share their policy experiences by forming networks among their renewable energy-focused organizations. All policy measures aim to reduce production costs while increasing the proportion of renewables to a country’s energy system. Meanwhile, long-term contracts with renewable energy providers, government commitment and control, and the establishment of long-term goals can assist developing nations in deploying renewable energy technology in their energy sector.

Why we’re publishing a series on DIY climate solutions

The climate crisis can seem intractable – especially in an election year. But the remarkable actions of individuals are reason for hope

The hottest year on record. Extreme drought , wildfires and flooding . Despairing scientists , wildlife loss and rampant waste . The sheer scale of the climate crisis can feel overwhelming.

And when it comes to taking serious action, politicians move at a glacial pace, and the very real possibility of another Donald Trump presidency could stymie progress even further.

In the face of such intractability, there’s hope to be found. Real change often happens first at the local level – in our own homes, backyards and communities.

In an election year when we know many US readers are frustrated by the lack of meaningful US and global action to tackle global heating, we wanted to hear from the people creating their own solutions to the environmental challenges they face – from waste and overconsumption to rising food and energy costs, extreme heat and drought.

In February, we launched a callout inviting US readers to tell us about their own DIY solutions. We had a lively response, with dozens of people writing in about their efforts. You’ll meet some of them in this series. You’ll also meet inspiring individuals who have turned their yards into micro-farms, started free clothing swaps, organized low-waste weddings, invented energy saving gadgets, and more.

This series will run throughout the year, and we’re on the hunt for more DIY projects to feature. We’d love to hear from a diverse range of people and communities; no project is too small! We are keen to feature stories from the US west and south-west, where issues such as drought, wildfires, extreme heat and air pollution are at their worst, but we welcome stories from anywhere in America.

If you would like to share your story, send us an email at [email protected] . Tell us a bit about yourself, your project and why you started it, and the impact it’s had. Please leave contact details; one of our reporters will get in touch if we are interested in finding out more

Should we fight climate change by re-engineering life itself?

by Jonathan Symons, Jacqueline Dalziell and Thom Dixon, The Conversation

Life has transformed our world over billions of years, turning a dead rock into the lush, fertile planet we know today. But human activity is currently transforming Earth again, this time by releasing greenhouse gases that are driving dramatic changes in our climate.

What if we could harness the power of living organisms to help rein in climate change ? The field of " engineering biology ," which uses genetic technology to engineer biological tools for solving specific problems, may be able to help.

Perhaps the most dramatic success to date of this nascent field is the mRNA vaccines that helped us weather the COVID pandemic. But engineering biology has enormous potential not only to help us adapt to climate change, but also to limit warming.

In our latest paper in Nature Communications , we reviewed some of the many ways engineering biology can aid the fight against climate change—and how governments and policymakers can make sure humanity reaps the benefits of the technology.

Could engineering biology help fight climate change?

We identified four ways engineering biology might help to mitigate climate change.

The first is finding better ways to make synthetic fuels that can directly replace fossil fuels. Many existing synthetic fuels are made from high-value crops such as corn and soybeans that might otherwise be used for food, so the fuels are expensive.

Some engineering biology research explores ways to make synthetic fuel from agricultural waste. These fuels could be cheaper and greener, and so might help speed up decarbonization.

For example, it would be much faster for airlines to decarbonize their existing fleets by switching to synthetic zero-carbon jet fuels, rather than waiting to replace their aircraft with yet-to-be-developed planes running on hydrogen or batteries.

The second is developing cost-effective ways to capture greenhouse emissions (from industrial facilities, construction and agriculture) and then use this waste for "biomanufacturing" valuable products (such as industrial chemicals or biofuels).

The third is replacing emissions-intensive production methods . For example, several companies are already using "precision fermentation" to produce synthetic milk that avoids the dairy industry's methane emissions. Other companies have produced microbes which promise to fix nitrogen in soil, and so help reduce use of fertilizers produced from fossil fuels .

Finally, the fourth is directly capturing greenhouse gases from the air. Bacteria engineered to consume atmospheric carbon, or plants bred to sequester more carbon in their roots, could in theory help reduce greenhouse gas levels in the atmosphere.

Beyond the technological and economic barriers, it's unclear whether these ideas will ever gain a social license. Given the "science fiction-like" character of some of these emerging climate responses it's essential that researchers be transparent and responsive to public attitudes .

Fact or science fiction?

Just how realistic are these ideas? Bringing a new product to market takes time, money and careful research.

Take solar power , for example. The first solar cell was created in the 1880s , and solar panels were installed on the White House roof in 1979, but it took many more decades of government support before solar power became a cost-competitive source of electricity.

The engineering biology sector is currently flooded with investor capital. However, the companies and projects attracting most investment are those with the greatest commercial value—typically in the medical, pharmaceutical, chemical and agricultural sectors.

By contrast, applications whose primary benefit is to reduce greenhouse emissions are unlikely to attract much private investment. For example, synthetic jet fuel is currently much more expensive than traditional jet fuel, so there's no rush of private investors seeking to support its commercialization.

Government (or philanthropic) support of some kind will be needed to nurture most climate-friendly applications through the slow process of development and commercialization.

Back to picking winners?

Which engineering biology applications deserve governments' assistance? Right now, it's mostly too early to tell.

Policymakers will need to continually assess the social and technical merits of proposed engineering biology applications.

If engineering biology is to play a significant role in fighting climate change, policymakers will need to engage with it skillfully over time.

We argue government support should include five elements.

First, continued funding for the basic scientific research that generates new knowledge, and new potential mitigation tools.

Second, public deliberation on engineering biology applications. Some new products—such as precision-fermented synthetic milk—might gain acceptance over time even if they at first seem unattractive. Others might never gain support. For this public deliberation to reflect the interests of all humanity, low- and middle-income countries will need to gain expertise in engineering biology.

Third, regulations should be aligned with public interest. Governments should be alert to the possibility of existing industries trying to use regulations to lock out new competitors. For instance, we may see efforts from animal-based agricultural producers to restrict who can use words like "milk" and "sausage" or to ban lab-grown meat completely .

Fourth, support commercialization and scale-up of promising technologies whose primary benefit is reducing greenhouse emissions. Governments might either fund this work directly or create other incentives—such as carbon pricing, tax credits or environmental regulations—that make private investment profitable.

Fifth, long-term procurement policies should be considered where large-scale deployment is needed to achieve climate goals. For example, the US Inflation Reduction Act provides unlimited tax credits to support direct air capture. While these incentives weren't designed with engineering biology in mind, they are technologically neutral and so might well support it.

A bioengineered future in Australia?

Governments are now involved in a global race to position their countries as leaders in the emerging green economy. Australia's proposed " future made in Australia " legislation is just one example.

Other governments have specific plans for engineering biology. For example, the United Kingdom committed £2 billion (A$3.8 billion) last year to an engineering biology strategy, while the US CHIPS and Science Act of 2022 called for the creation of a National Engineering Biology Research and Development Initiative.

If such interventions are to be economically and ecologically successful, they will need to work with still-developing technology.

Can policymakers work with this kind of uncertainty? One approach is to develop sophisticated assessments of the potential of different technologies and then invest in a diverse portfolio, knowing many of their bets will fail. Or, they might create technology-neutral instruments, such as tax credits and reverse auctions, and allow private industry to try to pick winners.

Engineering biology promises to contribute to a major step up in climate mitigation. Whether it lives up to this promise will depend on both public and policymakers' support. Given just how high the stakes are, there's work for all of us to do in reckoning with this technology's potential.

What Are the Causes of Climate Change?

We can’t fight climate change without understanding what drives it.

At the root of climate change is the phenomenon known as the greenhouse effect , the term scientists use to describe the way that certain atmospheric gases “trap” heat that would otherwise radiate upward, from the planet’s surface, into outer space. On the one hand, we have the greenhouse effect to thank for the presence of life on earth; without it, our planet would be cold and unlivable.

But beginning in the mid- to late-19th century, human activity began pushing the greenhouse effect to new levels. The result? A planet that’s warmer right now than at any other point in human history, and getting ever warmer. This global warming has, in turn, dramatically altered natural cycles and weather patterns, with impacts that include extreme heat, protracted drought, increased flooding, more intense storms, and rising sea levels. Taken together, these miserable and sometimes deadly effects are what have come to be known as climate change .

Detailing and discussing the human causes of climate change isn’t about shaming people, or trying to make them feel guilty for their choices. It’s about defining the problem so that we can arrive at effective solutions. And we must honestly address its origins—even though it can sometimes be difficult, or even uncomfortable, to do so. Human civilization has made extraordinary productivity leaps, some of which have led to our currently overheated planet. But by harnessing that same ability to innovate and attaching it to a renewed sense of shared responsibility, we can find ways to cool the planet down, fight climate change , and chart a course toward a more just, equitable, and sustainable future.

Here’s a rough breakdown of the factors that are driving climate change.

Natural causes of climate change

Human-driven causes of climate change, transportation, electricity generation, industry & manufacturing, agriculture, oil & gas development, deforestation, our lifestyle choices.

Some amount of climate change can be attributed to natural phenomena. Over the course of Earth’s existence, volcanic eruptions , fluctuations in solar radiation , tectonic shifts , and even small changes in our orbit have all had observable effects on planetary warming and cooling patterns.

But climate records are able to show that today’s global warming—particularly what has occured since the start of the industrial revolution—is happening much, much faster than ever before. According to NASA , “[t]hese natural causes are still in play today, but their influence is too small or they occur too slowly to explain the rapid warming seen in recent decades.” And the records refute the misinformation that natural causes are the main culprits behind climate change, as some in the fossil fuel industry and conservative think tanks would like us to believe.

Scientists agree that human activity is the primary driver of what we’re seeing now worldwide. (This type of climate change is sometimes referred to as anthropogenic , which is just a way of saying “caused by human beings.”) The unchecked burning of fossil fuels over the past 150 years has drastically increased the presence of atmospheric greenhouse gases, most notably carbon dioxide . At the same time, logging and development have led to the widespread destruction of forests, wetlands, and other carbon sinks —natural resources that store carbon dioxide and prevent it from being released into the atmosphere.

Right now, atmospheric concentrations of greenhouse gases like carbon dioxide, methane , and nitrous oxide are the highest they’ve been in the last 800,000 years . Some greenhouse gases, like hydrochlorofluorocarbons (HFCs) , do not even exist in nature. By continuously pumping these gases into the air, we helped raise the earth’s average temperature by about 1.9 degrees Fahrenheit during the 20th century—which has brought us to our current era of deadly, and increasingly routine, weather extremes. And it’s important to note that while climate change affects everyone in some way, it doesn’t do so equally: All over the world, people of color and those living in economically disadvantaged or politically marginalized communities bear a much larger burden , despite the fact that these communities play a much smaller role in warming the planet.

Our ways of generating power for electricity, heat, and transportation, our built environment and industries, our ways of interacting with the land, and our consumption habits together serve as the primary drivers of climate change. While the percentages of greenhouse gases stemming from each source may fluctuate, the sources themselves remain relatively consistent.

The cars, trucks, ships, and planes that we use to transport ourselves and our goods are a major source of global greenhouse gas emissions. (In the United States, they actually constitute the single-largest source.) Burning petroleum-based fuel in combustion engines releases massive amounts of carbon dioxide into the atmosphere. Passenger cars account for 41 percent of those emissions, with the typical passenger vehicle emitting about 4.6 metric tons of carbon dioxide per year. And trucks are by far the worst polluters on the road. They run almost constantly and largely burn diesel fuel, which is why, despite accounting for just 4 percent of U.S. vehicles, trucks emit 23 percent of all greenhouse gas emissions from transportation.

We can get these numbers down, but we need large-scale investments to get more zero-emission vehicles on the road and increase access to reliable public transit .

As of 2021, nearly 60 percent of the electricity used in the United States comes from the burning of coal, natural gas , and other fossil fuels . Because of the electricity sector’s historical investment in these dirty energy sources, it accounts for roughly a quarter of U.S. greenhouse gas emissions, including carbon dioxide, methane, and nitrous oxide.

That history is undergoing a major change, however: As renewable energy sources like wind and solar become cheaper and easier to develop, utilities are turning to them more frequently. The percentage of clean, renewable energy is growing every year—and with that growth comes a corresponding decrease in pollutants.

But while things are moving in the right direction, they’re not moving fast enough. If we’re to keep the earth’s average temperature from rising more than 1.5 degrees Celsius, which scientists say we must do in order to avoid the very worst impacts of climate change, we have to take every available opportunity to speed up the shift from fossil fuels to renewables in the electricity sector.

The factories and facilities that produce our goods are significant sources of greenhouse gases; in 2020, they were responsible for fully 24 percent of U.S. emissions. Most industrial emissions come from the production of a small set of carbon-intensive products, including basic chemicals, iron and steel, cement and concrete, aluminum, glass, and paper. To manufacture the building blocks of our infrastructure and the vast array of products demanded by consumers, producers must burn through massive amounts of energy. In addition, older facilities in need of efficiency upgrades frequently leak these gases, along with other harmful forms of air pollution .

One way to reduce the industrial sector’s carbon footprint is to increase efficiency through improved technology and stronger enforcement of pollution regulations. Another way is to rethink our attitudes toward consumption (particularly when it comes to plastics ), recycling , and reuse —so that we don’t need to be producing so many things in the first place. And, since major infrastructure projects rely heavily on industries like cement manufacturing (responsible for 7 percent of annual global greenhouse gas), policy mandates must leverage the government’s purchasing power to grow markets for cleaner alternatives, and ensure that state and federal agencies procure more sustainably produced materials for these projects. Hastening the switch from fossil fuels to renewables will also go a long way toward cleaning up this energy-intensive sector.

The advent of modern, industrialized agriculture has significantly altered the vital but delicate relationship between soil and the climate—so much so that agriculture accounted for 11 percent of U.S. greenhouse gas emissions in 2020. This sector is especially notorious for giving off large amounts of nitrous oxide and methane, powerful gases that are highly effective at trapping heat. The widespread adoption of chemical fertilizers , combined with certain crop-management practices that prioritize high yields over soil health, means that agriculture accounts for nearly three-quarters of the nitrous oxide found in our atmosphere. Meanwhile, large-scale industrialized livestock production continues to be a significant source of atmospheric methane, which is emitted as a function of the digestive processes of cattle and other ruminants.

But farmers and ranchers—especially Indigenous farmers, who have been tending the land according to sustainable principles —are reminding us that there’s more than one way to feed the world. By adopting the philosophies and methods associated with regenerative agriculture , we can slash emissions from this sector while boosting our soil’s capacity for sequestering carbon from the atmosphere, and producing healthier foods.

Oil and gas lead to emissions at every stage of their production and consumption—not only when they’re burned as fuel, but just as soon as we drill a hole in the ground to begin extracting them. Fossil fuel development is a major source of methane, which invariably leaks from oil and gas operations : drilling, fracking , transporting, and refining. And while methane isn’t as prevalent a greenhouse gas as carbon dioxide, it’s many times more potent at trapping heat during the first 20 years of its release into the atmosphere. Even abandoned and inoperative wells—sometimes known as “orphaned” wells —leak methane. More than 3 million of these old, defunct wells are spread across the country and were responsible for emitting more than 280,000 metric tons of methane in 2018.

Unsurprisingly, given how much time we spend inside of them, our buildings—both residential and commercial—emit a lot of greenhouse gases. Heating, cooling, cooking, running appliances, and maintaining other building-wide systems accounted for 13 percent of U.S. emissions overall in 2020. And even worse, some 30 percent of the energy used in U.S. buildings goes to waste, on average.

Every day, great strides are being made in energy efficiency , allowing us to achieve the same (or even better) results with less energy expended. By requiring all new buildings to employ the highest efficiency standards—and by retrofitting existing buildings with the most up-to-date technologies—we’ll reduce emissions in this sector while simultaneously making it easier and cheaper for people in all communities to heat, cool, and power their homes: a top goal of the environmental justice movement.

Another way we’re injecting more greenhouse gas into the atmosphere is through the clearcutting of the world’s forests and the degradation of its wetlands . Vegetation and soil store carbon by keeping it at ground level or underground. Through logging and other forms of development, we’re cutting down or digging up vegetative biomass and releasing all of its stored carbon into the air. In Canada’s boreal forest alone, clearcutting is responsible for releasing more than 25 million metric tons of carbon dioxide into the atmosphere each year—the emissions equivalent of 5.5 million vehicles.

Government policies that emphasize sustainable practices, combined with shifts in consumer behavior , are needed to offset this dynamic and restore the planet’s carbon sinks .

The decisions we make every day as individuals—which products we purchase, how much electricity we consume, how we get around, what we eat (and what we don’t—food waste makes up 4 percent of total U.S. greenhouse gas emissions)—add up to our single, unique carbon footprints . Put all of them together and you end up with humanity’s collective carbon footprint. The first step in reducing it is for us to acknowledge the uneven distribution of climate change’s causes and effects, and for those who bear the greatest responsibility for global greenhouse gas emissions to slash them without bringing further harm to those who are least responsible .

The big, climate-affecting decisions made by utilities, industries, and governments are shaped, in the end, by us : our needs, our demands, our priorities. Winning the fight against climate change will require us to rethink those needs, ramp up those demands , and reset those priorities. Short-term thinking of the sort that enriches corporations must give way to long-term planning that strengthens communities and secures the health and safety of all people. And our definition of climate advocacy must go beyond slogans and move, swiftly, into the realm of collective action—fueled by righteous anger, perhaps, but guided by faith in science and in our ability to change the world for the better.

If our activity has brought us to this dangerous point in human history, breaking old patterns can help us find a way out.

REVIEW article

The linkage between global financial crises, corporate social responsibility and climate change: unearthing research opportunities through bibliometric reviews provisionally accepted.

• 1 Kotebe University of Education, Ethiopia
• 2 University of Johannesburg, South Africa

The final, formatted version of the article will be published soon.

Financial matters, corporate social responsibility (CSR), climate change, and other sustainable solutions all work in tandem. In order to provide a thorough understanding of the integration between various components during crises, it is necessary to provide knowledge of the interaction between financial, societal, and environmental aspects. In order to accomplish this, hundreds of papers were examined and presented using bibliometric analysis. The study demonstrated that, when examining financial crises in relation to CSR and climate change, sustainability issues were clearly examined. Sustainability, environmental economics, governance approaches, and sustainable development are some of the main issues in this comprehensive subject. Besides, the emerging topics that need more research include organizational resilience, global financial crises, and sustainable performance, while there are no specific themes developed in the subject matter that integrate financial crises, CSR, and climate change. Thus, future researchers need to provide new insights on the integration of these concepts.
