Essay on Prevention of Global Warming for Students and Children

500 words essay on prevention of global warming.

Global warming is a term you must have heard by now as it is very prevalent in today’s world. Moreover, it has become a very dangerous environmental issue which we must resolve as soon as possible. If we do not prevent it now, soon we will find it hard to survive on this planet.

Every person needs to contribute equally to help prevent global warming. Similarly, we must identify the causes that are contributing to this dangerous phenomenon and work hard to find solutions. Furthermore, we must immediately put a halt to all those activities which are causing global warming .

Causes of Global Warming

There are many activities through which global warming is happening. Mostly human activities are contributing to this damaging phenomenon. The carbon dioxide levels are increasing in the air which is causing global warming. Moreover, the increase in greenhouse gases is also contributing to this phenomenon.

Furthermore, the usages of hot water for various purposes like bathing, cleaning and more release gases contribute to it. After that, when we make use of ordinary bulbs instead of LED lights, we contribute majorly to global warming. Similarly, the way people leave their electronic devices unattended when not in use also plays a big role.

Most importantly, deforestation and cutting plants everywhere just make it worse for our planet. The way we burn wood and fossil fuels only makes the condition of global warming worse. Similarly, when we use too much of automobiles that release harmful toxins in the air, the temperature of earth increases and causes global warming. In order to prevent global warming, we must adopt an eco-friendly lifestyle to make the future safe for our future generations.

Ways to Prevent Global Warming

There are many changes we can bring about in our life both big and small to prevent global warming and save our planet. Firstly, we must stop deforestation in all forms. Do not cut down more trees as it will only worsen the level of carbon dioxide in the air. Instead, encourage people to plant even more trees to create a fine balance in nature.

Moreover, it reduces the usage of energy everywhere. It does not matter if you are at your home or at your office, the higher the energy used the more the carbon dioxide produced. Thus, do not waste electricity as it requires the burning of fossil fuels. As a result of the burning of fossil fuels , greenhouse gases in the atmosphere increase rapidly and contribute to global warming. Moreover, reduce the carbon footprint and do not travel through planes that often.

Most importantly, replace all your ordinary bulbs with LED lights. It will help in reducing the use of energy by a massive amount. Similarly, do not waste that energy. Instead of becoming more dependent, we need to reduce our dependence on fossil fuels and electricity right away.

Opt for eco-friendly options like solar energy and win power. Take up the habit of recycling and reusing. Do not throw away things instead learn to reuse them properly. Further, carpool with your neighbors and relatives to not contribute to automobile exhausts and emissions.

Rising sea levels. Raging storms. Searing heat. Ferocious fires. Severe drought. Punishing floods. The effects of climate change are already threatening our health, our communities, our economy, our security, and our children’s future.

What can you do? A whole lot, as it turns out. Americans, on average, produce 21 tons of carbon a year, about four times the global average. Personal action is, of course, no substitute for meaningful government policies. We still must limit carbon pollution and aggressively move away from dirty fossil fuels toward cleaner power.

But it’s important to remember the equally vital contributions that can be made by private citizens—which is to say, by you. “Change only happens when individuals take action,” says clean energy advocate Aliya Haq. “There’s no other way, if it doesn’t start with people.”

Here are a dozen easy, effective ways each one of us can make a difference.

1. Speak up!

What’s the single biggest way you can make an impact on global climate change? “Talk to your friends and family, and make sure your representatives are making good decisions,” Haq says. By voicing your concerns—via social media or, better yet, directly to your elected officials —you send a message that you care about the warming world. Encourage Congress to enact new laws that limit carbon emissions and require polluters to pay for the emissions they produce. “The main reason elected officials do anything difficult is because their constituents make them,” Haq says. You can help protect public lands, stop offshore drilling, and more here .

2. Power your home with renewable energy.

Choose a utility company that generates at least half its power from wind or solar and has been certified by Green-e Energy , an organization that vets renewable energy options. If that isn’t possible for you, take a look at your electric bill; many utilities now list other ways to support renewable sources on their monthly statements and websites.

3. Weatherize, weatherize, weatherize.

“Building heating and cooling are among the biggest uses of energy,” Haq says. Indeed, heating and air-conditioning account for almost half of home energy use. You can make your space more energy efficient by sealing drafts and ensuring it’s adequately insulated. You can also claim federal tax credits for many energy efficiency home improvements. To help you figure out where to start, you could also get a home energy audit, which some utilities offer free of charge. (Alternatively, you can hire a professional to come to your home and perform one; the Inflation Reduction Act offers a partial tax credit for this.) The EPA’s Home Energy Yardstick gives you a simple assessment of your home’s annual energy use compared with similar homes.

4. Invest in energy-efficient appliances.

Since they were first implemented nationally in 1987, efficiency standards for dozens of appliances and products have kept 2.3 billion tons of carbon dioxide out of the air. That’s about the same amount as the annual carbon pollution coughed up by nearly 440 million cars. “Energy efficiency is the lowest-cost way to reduce emissions,” Haq says. When shopping for refrigerators, washing machines, heat pump water heaters , and other appliances, look for the Energy Star label. It will tell you which are the most efficient. (There may also be rebates to earn from your purchase of Energy Star–certified products.)

And when you’re ready to swap out your old machines, don’t just put them on the curb: Recycling an old refrigerator through the EPA’s Responsible Appliance Disposal Program can prevent an additional 10,000 pounds of carbon pollution because the global-warming pollutants in the refrigerants and foam would be properly captured rather than vented to the air.

5. Reduce water waste.

Saving water reduces carbon pollution, too. That's because it takes a lot of energy to pump, heat, and treat your water. So take shorter showers, turn off the tap while brushing your teeth, and switch to WaterSense -labeled fixtures and appliances. The EPA estimates that if just one out of every 100 American homes were retrofitted with water-efficient fixtures, about 100 million kilowatt-hours of electricity per year would be saved—avoiding 80,000 tons of global warming pollution .

6. Actually eat the food you buy—and compost what you can’t.

Approximately 10 percent of U.S. energy use goes into growing, processing, packaging, and shipping food—about 40 percent of which winds up in the landfill. “If you’re wasting less food, you’re likely cutting down on energy consumption,” Haq says. As for the scraps you can’t eat or the leftovers you don’t get to, collect them in a compost bin instead of sending them to the landfill where they release methane. Recycling food and other organic waste into compost provides a range of environmental benefits, including improving soil health, reducing greenhouse gas emissions, recycling nutrients, and mitigating the impact of droughts.

7. Buy better bulbs.

LED light bulbs use one-sixth the amount of energy to deliver the same amount of light as conventional incandescents and last at least 10 times longer. They’re also cheaper in the long run: A 10-watt LED that replaces your traditional 60-watt bulb will save you $125 over the light bulb’s life. And because the average American home has around 40 to 50 light bulbs, this is a simple swap that will reap huge rewards. If every household in the United States replaced just one incandescent with an Energy Star–labeled LED, we would prevent seven billion pounds of carbon pollution per year. That’s equivalent to the emissions of about 648,000 cars.

8. Pull the plug(s).

Taken together, the outlets in your home are likely powering about 65 devices—an average load for a home in the United States. Audio and video devices, cordless vacuums and power tools, and other electronics use energy even when they're not charging. This "idle load" across all U.S. households adds up to the output of 50 large power plants in the country . So don't leave fully charged devices plugged into your home's outlets, unplug rarely used devices or plug them into power strips and timers, and adjust your computers and monitors to automatically power down to the lowest power mode when not in use.

9. Drive a fuel-efficient vehicle.

Gas-smart cars, such as hybrids and fully electric vehicles, save fuel and money . And once all cars and light trucks meet 2025’s clean car standards, which means averaging 54.5 miles per gallon, they’ll be a mainstay. For good reason: Relative to a national fleet of vehicles that averaged only 28.3 miles per gallon in 2011, Americans will spend $80 billion less at the pump each year and cut their automotive emissions by half. Before you buy a new set of wheels, compare fuel-economy performance here .

10. Maintain your ride.

If all Americans kept their tires properly inflated, we could save 1.2 billion gallons of gas each year. A simple tune-up can boost miles per gallon anywhere from 4 percent to 40 percent, and a new air filter can get you a 10 percent boost. Also, remove unnecessary accessories from your car roof. Roof racks and clamshell storage containers can reduce fuel efficiency by as much as 5 percent.

11. Rethink planes, trains, and automobiles.

Choosing to live in walkable smart-growth cities and towns with quality public transportation leads to less driving, less money spent on fuel, and less pollution in the air . Less frequent flying can make a big difference, too. “Air transport is a major source of climate pollution,” Haq says. “If you can take a train instead, do that.” If you must fly, consider purchasing carbon offsets to counterbalance the hefty carbon pollution associated with flying. But not all carbon offset companies are alike. Do your homework to find the best supplier.

12. Reduce, reuse, and recycle.

In the United States, the average person generates 4.5 pounds of trash every day. Fortunately, not all the items we discard end up in landfills; we recycle or compost more than one-third of our trash. In 2014 this saved carbon emissions equivalent to the yearly output of 38 million passenger cars . But we could be doing so much more. “ Reduce should always be the number-one priority,” says NRDC senior resource specialist Darby Hoover . And to reap the environmental benefits of “recyclable” goods, you must recycle according to the rules of your municipality, since systems vary widely by location . Search your municipality’s sanitation department (or equivalent) webpage to learn exactly what you can place in the recycling bin, as counties and cities often differ in what they accept.

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."

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.

Responding to the Climate Threat: Essays on Humanity’s Greatest Challenge

A new book co-authored by MIT Joint Program Founding Co-Director Emeritus Henry Jacoby

From the Back Cover

This book demonstrates how robust and evolving science can be relevant to public discourse about climate policy. Fighting climate change is the ultimate societal challenge, and the difficulty is not just in the wrenching adjustments required to cut greenhouse emissions and to respond to change already under way. A second and equally important difficulty is ensuring widespread public understanding of the natural and social science. This understanding is essential for an effective risk management strategy at a planetary scale. The scientific, economic, and policy aspects of climate change are already a challenge to communicate, without factoring in the distractions and deflections from organized programs of misinformation and denial. 

Here, four scholars, each with decades of research on the climate threat, take on the task of explaining our current understanding of the climate threat and what can be done about it, in lay language―importantly, without losing critical  aspects of the natural and social science. In a series of essays, published during the 2020 presidential election, the COVID pandemic, and through the fall of 2021, they explain the essential components of the challenge, countering the forces of distrust of the science and opposition to a vigorous national response.  

Each of the essays provides an opportunity to learn about a particular aspect of climate science and policy within the complex context of current events. The overall volume is more than the sum of its individual articles. Proceeding each essay is an explanation of the context in which it was written, followed by observation of what has happened since its first publication. In addition to its discussion of topical issues in modern climate science, the book also explores science communication to a broad audience. Its authors are not only scientists – they are also teachers, using current events to teach when people are listening. For preserving Earth’s planetary life support system, science and teaching are essential. Advancing both is an unending task.

• Solving Climate Change

Humans have warmed the planet by approximately 1.0°C (1.8°F) in the past 150 years, which has increased the risk of wildfires, hurricanes, heat waves, droughts, and floods. Sea level is rising, and ice is melting. All of this is making life on Earth much more difficult.

We caused the problem by increasing the amount of greenhouse gases in the atmosphere, but we have the ability to keep the amount of warming low enough to be survivable. Communities and nations around the world are taking action to solve climate change. There’s much more that needs to be accomplished, so keep reading to learn what can be done to keep our planet as cool as possible.

Global Warming Targets

If we keep the amount of climate warming low enough, we can adapt, finding ways to live and even thrive. But what is low enough? The planet has already warmed 1°C. How much more can we handle?

Since the 1990s, scientists and policymakers around the world had considered the goal to be a limit of 2°C (3.6°F) above pre-industrial levels (which was before we started burning fossil fuels). But in 2018, the Intergovernmental Panel on Climate Change (IPCC) reported on what we know about the impacts of global warming of 1.5°C (2.7°F) compared to 2°C.

They found that with a warming of 2°C, the impacts are more severe than 1.5°C. For example, heat waves would be hotter, rains would be heavier, and sea level would rise more. There are higher risks to health, the food supply, water, ecosystems, and economic growth with 2°C warming compared with 1.5°C. Overall, 1.5°C warming gives us a better chance of adapting to climate change, although there are impacts, like the loss of some ecosystems, which may be long-lasting or irreversible.

How Can We Tackle Climate Change?

There are several different strategies when it comes to dealing with climate change. Reducing greenhouse gases  is a direct way to help slow or stop climate change since excess greenhouse gases are what are causing the climate to warm. This can mean switching to power sources that don’t emit greenhouse gases and taking carbon dioxide out of the air by planting forests and conserving ecosystems. New research on ways to pull carbon dioxide out of the atmosphere could potentially provide other solutions in the future. Researchers are also studying whether we could safely limit the amount of sunlight that gets to Earth in the future while we are reducing emissions.

Unfortunately, the planet is already warming and we are seeing the impacts of climate change. Even if we stop emitting greenhouse gases in the next decade or two, we will be facing more climate change this century, which is why finding ways to adapt to climate change is also important to keep our planet as livable as possible.  

How Can We Limit Warming to 1.5°C?

To keep the total warming limited to 1.5°C, we need to act quickly to change energy sources, how land is used, how industry operates, and our urban environments, including buildings and transportation. For example, industries can reduce emissions with new and existing technologies and practices, such as switching power sources, using sustainable materials like bioplastic, and capturing carbon emissions at factories so they don’t make it into the atmosphere.

There are many ways that we can do this. The IPCC 2018 report analyzed different scenarios that would help us meet the 1.5°C target. Below are descriptions of four scenarios that would meet the target, and a graph showing how much each could reduce carbon dioxide emissions.

• The innovation scenario (P1): We develop innovations that lead to lower energy demand while living standards rise, especially in the Southern Hemisphere. Needing less energy helps us make the transition to renewable energy. More forests are planted to take carbon dioxide out of the air .
• The sustainability scenario (P2): We use less energy to produce goods and provide services, there is more international cooperation, and there are shifts toward sustainable consumption patterns. A switch to mostly renewable energy helps us emit less carbon dioxide, and there is also some carbon capture and storage technology used at power plants to stop CO 2 from getting into the atmosphere. Land is well-managed and there are lower emissions from farms.
• The middle-of-the-road scenario (P3): There is more energy demand in the future, but we increase renewable energy and nuclear power and decrease fossil fuel use so that we can decrease emissions. Where there are still fossil fuels burned at power plants, carbon capture and storage are used. Bioenergy power plants are also developed, which burn plants like switchgrass to create electricity, and then capture the CO 2 .
• The energy-intensive scenario (P4): Economic growth and globalization cause more people to have a lifestyle that emits lots of greenhouse gases — for example, by driving cars, taking flights, and eating meat. In this scenario, energy comes from oil, gas, nuclear power, and renewables. We have a lot of emissions to reduce and some catching up to do because we have high emissions in the next couple of decades. We do this with carbon capture and storage and removing carbon from the air with bioenergy power plants that capture CO 2 .

The graph above shows the amount of carbon dioxide emissions per year through the 21st century for each scenario that limits global warming to 1.5°C (described above: P1 to P4). The shaded area shows the full range of options studied in the IPCC 2018 report. Credit: IPCC

• Essay on Effects of Global Warming

Introduction

Our world, as well as all living things such as animals, birds, insects, trees, and plants, were created by nature. They all have the right to live their lives as they see fit, but the human being is the most perplexing of all living creatures. For our own needs and greed, we humans are killing nature, and we will pay the price in the form of catastrophe. Here we have provided both long and short essays on the effects of Global Warming for students of Classes 1 to 12.

Long Effect of Global Warming Essay in English

As carbon dioxide (CO 2 ) and other air pollution and greenhouse gases build up in the atmosphere, they absorb sunlight and solar radiation that has bounced off the earth's surface, resulting in global warming. Normally, this radiation will disperse into space, but these contaminants, which can remain in the atmosphere for years or decades, trap the heat and cause the earth to get hotter. The greenhouse effect is the result of this.

So, What causes Global Warming?

Natural Causes of Global Warming:

For decades, the world has been shifting. The natural rotation of the sun causes global warming by changing the strength of sunlight and bringing it closer to the earth.

Greenhouse emissions are another contributor to global warming. 

Carbon monoxide and sulphur dioxide are greenhouse gases that absorb solar heat rays and prevent them from escaping the earth's surface. The earth's temperature has increased as a result of this.

Another factor that contributes to global warming is volcanic eruptions. A single volcanic eruption, for example, can release a significant amount of carbon dioxide and ash into the atmosphere.

As carbon dioxide levels rise, the earth's temperature rises, and greenhouse gases absorb solar radiation.

Finally, methane is a contributor to global warming. Methane is a greenhouse gas as well. Methane is 20 times more effective than carbon dioxide at trapping heat in the atmosphere. Methane gas can usually be used in a variety of places. Cattle, landfills, natural gas, petroleum systems, coal mining, mobile explosions, and industrial waste processes are only a few examples.

Human Influences on Global Warming:

Humans are more responsible for global warming than natural causes. Because of modern human lifestyles, the earth has been evolving for many years and continues to do so. Industrial production, fossil fuel combustion, mining, cattle rearing, and deforestation are all examples of human activities.

The industrial revolution is the first thing. Industrial devices have been powered by fossil fuels. All we use is made up of fossil fuels. When we purchase a cell phone, for example, the process of manufacturing the phone involves machines, which use fossil fuels, and carbon dioxide is released into the environment during the process. Aside from industry, transportation, such as automobiles, emits carbon dioxide by the exhaust.

Mining is another problem. Methane would be trapped under the earth during the mining process. Furthermore, raising cattle results in the release of methane in the form of manure. Cattle, on the other hand, are noteworthy because they are equally responsible for the occurrence of global warming.

Then there's deforestation, which is by far the most common problem. Humans have been cutting down trees to manufacture documents, wood, build homes, and other things, so deforestation is a human factor.

Humans also emit carbon dioxide as they breathe. As a result, carbon dioxide has been released into the atmosphere by millions of people. If human deforestation continues, the carbon dioxide released by human breathing will remain in the atmosphere.

Effects of Global Warming

Every year, scientists learn more about the effects of global warming, and all agree that if current patterns continue, environmental, economic, and health impacts are likely. Here's a taste of what we can expect in the coming months:

Melting glaciers, early snowmelt, and extreme droughts would intensify water shortages in the American West, raising the risk of wildfires.

Coastal flooding will occur along the Eastern Seaboard, especially in Florida, as well as in other areas such as the Gulf of Mexico.

New pests will wreak havoc on forests, crops, and towns, as will heat waves, heavy rains, and increased flooding.

Many plant and animal species could become extinct if ecosystems such as coral reefs and Alpine meadows are disrupted.

Increased pollen-producing ragweed growth, higher levels of air pollution, and the spread of conditions favorable to pathogens and mosquitoes will make allergies, asthma, and infectious disease outbreaks more likely.

In the above effect of global warming essay in English, we have discussed in depth all the natural causes of global warming and how humans have contributed towards its drastic increase. Below we have provided short effects of the Global Warming essay for students of Classes 1 to 5.

Effect of Global Warming Short Essay

Since hundreds of years ago, greenhouse gases have remained in the atmosphere for several years. Global warming, on the other hand, would have disastrous consequences for the planet. If global warming persists, a slew of negative consequences will emerge. Melting polar ice caps, economic effects, warming oceans, and more storms, disease transmission, and earthquakes are all examples.

The melting of the polar ice caps is the first consequence. The ice at the North Pole will melt as the temperature increases. Since melting glaciers become seas, the first result of ice melting would be an increase in sea levels. “If the ice melted today, the seas will rise about 230 feet,” according to the National Snow and Ice Data Center. Many low-lying areas, such as the Netherlands, are affected. Once the North Pole melts, the Netherlands will be submerged in water. However, that will not happen easily, and the sea level will continue to rise.

Another impact is the loss of habitat for some species. Polar bears and tropical frogs would become extinct as a result of climate change. Furthermore, since animals are not like humans, different birds will migrate to other locations. They are unable to adjust to changes in their climate, such as temperature or living conditions.

The next result is that more hurricanes will occur, with economic implications. Houses are damaged by hurricanes, and the government will have to spend billions of dollars to repair the damage, and people will need places to stay or will be killed. When a disaster strikes, many people die and illnesses spread. Diseases are more serious because they can spread rapidly to other people, allowing more people to catch the disease. Diseases can also become more serious as the weather changes.

Importance of an Essay on Global Warming

The essay on global warming is important because it will help students to understand the effects of global warming and how it impacts life on earth. They will then be aware and likewise, share their knowledge with their fellow beings and make them conscious of the human actions that lead to an increase in global warming.

Climate change is an issue that humans are actually facing, and the ones causing these problems are humans. Although it is difficult to avoid global warming, people can indeed help to mitigate and slow its effects. If no action is taken to address this problem, people will perish as a result of cli mate change and natural disasters. Humans changed the world; now it's time for humans to change themselves.

FAQs on Essay on Effects of Global Warming

1. State Some Ways to Reduce Global Warming ?

We should reduce the emission of greenhouse gases into the atmosphere to reduce global warming. 

We can minimise global warming by reducing our use of oil, electricity, and other practices that contribute to global warming. To save fuel, we should opt for a hybrid vehicle that uses less gasoline. 

Taking public transportation or carpooling to work has the potential to minimise carbon dioxide emissions while still saving money. 

Recycling is another way to help combat global warming. Reusing plastic bags, bottles, documents, or glass may help to minimise waste. 

Finally, open burning should be forbidden, such as the burning of dry leaves or garbage. When garbage is burned with plastic, carbon dioxide and toxic gases are released. Furthermore, since global temperatures are rising, the government should minimise deforestation. Trees will assist in the reduction of global warming.

2. Define Global Warming ?

Global warming is the long-term warming of Earth's climate system that has been observed since the pre-industrial era (between 1850 and 1900) as a result of human activities, mainly fossil fuel combustion, which raises heat-trapping greenhouse gas levels in the atmosphere. The words are sometimes used interchangeably, though the latter applies to both human- and naturally-caused warming, as well as the implications for our world. The average rise in Earth's global surface temperature is the most common metric.

4. Why is plastic bad for the environment?

Nonrenewable resources such as coal, natural gas, and crude oil are used to make plastics. Because plastic bags take a long time to disintegrate, they have a substantial environmental impact. If toxic compounds are allowed to deteriorate, there is concern that they will leak into the environment. Rather than degrading completely, plastic dissolves into smaller chunks and microscopic particles known as microplastics. Microplastics regularly end up in bodies of water, endangering animals. Furthermore, dangerous chemicals are released into the soil when plastic bags degrade in the sun, and harmful substances are released into the air when plastic bags are burnt, resulting in air pollution. All of these reasons make plastic one of the most harmful materials on the earth for all of these reasons. Plastic is one of the main reasons for Global Warming and thus needs to be eliminated from the world.

5. Is writing an essay hard?

Essay writing is a difficult task that needs a great deal of study, time, and focus. It's also an assignment that you can divide down into manageable chunks such as introduction, main content, and conclusion. Breaking down and focusing on each individually makes essay writing more pleasant. It's natural for students to be concerned about writing an essay. It's one of the most difficult tasks to do, especially for people who aren't confident in their writing abilities. While writing a decent essay is difficult, the secret to being proficient at it is reading a lot of books, conducting extensive research on essential topics, and practicing essay writing diligently.

6. Who prepares the essay on global warming for Vedantu?

The panel of experts have created the essay after analyzing important essay topics that have been repeatedly asked in various examinations. The Essays that are provided by Vedantu are not only well-structured but also accurate and concise. They are aptly suited for young students with limited vocabulary. For best results, the students are advised to go through multiple essays and practice the topics on their own to inculcate the habits of time management and speed.

7. What will be the impact on the phenomena of Global Warming if we ban plastic and petroleum products?

Plastic and petroleum product bans can undoubtedly aid in the conservation of non-renewable resources that, once gone, may not be recovered. Plastic use has two significant negative consequences: it emits carbon dioxide, which contributes to the greenhouse effect, and it increases rubbish collecting in landfills and seas. Bans should be implemented since they are successful in eliminating large amounts of plastic trash. Plastic can be eliminated; but, it will need advances in engineering and applied science, and the capability to do so currently exists. With each passing year, humanity's reliance on plastic gets greater. Thus, one of the only ways to eliminate or reduce global warming is through the elimination of the use of plastic and petroleum products.

Can we slow or even reverse global warming?

Yes.  While we cannot stop global warming overnight, we can slow the rate and limit the amount of global warming by reducing human emissions of heat-trapping gases and soot (“black carbon”). 

If all human emissions of heat-trapping gases were to stop today, Earth’s temperature would continue to rise for a few decades as ocean currents bring excess heat stored in the deep ocean back to the surface.  Once this excess heat radiated out to space, Earth’s temperature would stabilize. Experts think the additional warming from this “hidden” heat are unlikely to exceed 0.9° Fahrenheit (0.5°Celsius). With no further human influence, natural processes would begin to slowly remove the excess carbon dioxide from the atmosphere, and global temperatures would gradually begin to decline.

Change in heat content in the upper 2,300 feet (700 meters) of the ocean from 1993-2020. Between 1993–2019, heat content rose by up to 6 Watts per square meter in parts of the ocean (dark orange). Some areas lost heat (blue), but overall, the ocean gained more heat than it lost. The changes in areas covered with the gray shading were not statistically significant. NOAA Climate.gov image, based on data from NCEI.

It’s true that without dramatic action in the next couple of decades, we are unlikely to keep global warming in this century below 2.7° Fahrenheit (1.5° Celsius) compared to pre-industrial temperatures—a threshold that experts say offers a lower risk of serious negative impacts. But the more we overshoot that threshold, the more serious and widespread the negative impacts will be, which means that it is never “too late” to take action.

In response to a request from the U.S. Congress, the U.S. National Academy of Sciences published a series of peer-reviewed reports, titled  America's Climate Choices , to provide authoritative analyses to inform and guide responses to climate change across the nation. Relevant to this question, the NAS report titled  Limiting the Magnitude of Future Climate Change  explains policies that could be adopted to slow or even reverse global warming. The report says, "Meeting internationally discussed targets for limiting atmospheric greenhouse gas concentrations and associated increases in global average temperatures will require a major departure from business as usual in how the world uses and produces energy."

Transitioning to energy sources that do not emit greenhouse gases, such as solar, wind, biofuels, and nuclear, can slow the pace of climate change, though these energy sources face hurdles ranging from manufacturing capacity to debates about where to install some facilities. Images courtesy Energy.gov.

Alternative methods to slow or reduce global warming have been proposed that are, collectively, known as "climate engineering" or "geoengineering." Some geoengineering proposals involve cooling Earth's surface by injecting reflective particles into the upper atmosphere to scatter and reflect sunlight back to space. Other proposals involve seeding the oceans with iron to stimulate large-scale phytoplankton blooms, thereby drawing down carbon dioxide out of the atmosphere through photosynthesis. Such methods could work, in principle, but many climate scientists oppose undertaking geoengineering until we have a much better understanding of the possible side effects. Additionally, there are unresolved legal and ethical issues surrounding geoengineering.

Given these concerns, the  American Meteorological Society published a position paper  (readopted in January 2013) in which it said: "...research to date has not determined whether there are large-scale geoengineering approaches that would produce significant benefits, or whether those benefits would substantially outweigh the detriments. Indeed, geoengineering must be viewed with caution because manipulating the Earth system has considerable potential to trigger adverse and unpredictable consequences."

Global Warming Speech: 1, 2, 3-5 Minute Speech

• Updated on  
• Feb 3, 2024

Global warming refers to the long-term rise in Earth’s average surface temperature. Since the 18th-century Industrial Revolution in European Countries, global annual temperature has increased in total by a little more than 1 degree Celsius. Global Warming is one of the most concerning issues facing us, as it threatens the existence of life on Earth. Greenhouse gas emissions, deforestation, industrial processes, waste management, etc are all reasons for global warming.

Did you know: Antarctica is losing ice mass at an average rate of about 150 billion tons per year, and Greenland is losing about 270 billion tons per year, adding to sea level rise?

Today, weather prediction has been becoming more complex with every passing year, with seasons more indistinguishable, and the general temperatures hotter. The number of natural disasters like hurricanes, cyclones, droughts, floods, etc., has risen steadily since the onset of the 21st century. The supervillain behind all these changes is Global Warming. The name is quite self-explanatory; it means the rise in the temperature of the Earth. Since childhood, we all have heard about it, but just as a formality, let us first understand what global warming is!

This Blog Includes:

Short global warming speech 100-150 words (1 minute), global warming speech 250 words (2 minutes), global warming speech 500- 700 words (3- 5 minutes), 10-line global warming speech, causes of global warming, ways to tackle global warming.

It means a rise in global temperature due to the greenhouse gases in the atmosphere due to human activities and inventions. In scientific words, Global Warming is when the earth heats (the temperature rises). It occurs when the earth’s atmosphere warms up as a result of the sun’s heat and light being trapped by greenhouse gases such as carbon dioxide, water vapour, nitrous oxide, and methane. Many people, animals, and plants are harmed by this. Many people die because they can’t handle the shift.

Good morning to everyone present here today I am going to present a speech on global warming. Global Warming is caused by the increase of carbon dioxide levels in the earth’s atmosphere and is a result of human activities that have been causing harm to our environment for the past few centuries now. Global Warming is something that can’t be ignored and steps have to be taken to tackle the situation globally. The average temperature is constantly rising by 1.5 degrees Celsius for the last few years. The best method to prevent future damage to the earth, cutting down more forests should be banned and Afforestation should be encouraged. Start by planting trees near your homes and offices, participate in events, and teach the importance of planting trees. It is impossible to undo the damage but it is possible to stop further harm.

Good morning everyone and topic of my speech today is global warming. Over a long period, it is observed that the Earth’s temperature is rising rapidly. This affected the wildlife, animals, humans, and every living organism on earth. Glaciers have been melting, and many countries have started water shortages, flooding, erosion and all this is because of global warming. No one can be blamed for global warming except for humans. Human activities such as gases released from power plants, transportation, and deforestation have resulted in the increase of gases such as carbon dioxide, CFCs, and other pollutants in the earth’s atmosphere. The main question is how can we control the current situation and build a better world for future generations. It starts with little steps by every individual. Start using cloth bags made from sustainable materials for all shopping purposes, instead of using the high-watt lights use the energy-efficient bulbs, switch off the electricity, don’t waste water, abolish deforestation and encourage planting more trees. Shift the use of energy from petroleum or other fossil fuels to wind and solar energy. Instead of throwing out the old clothes donate them to someone so that it is recycled. Donate old books, don’t waste paper.  Above all, spread awareness about global warming. Every little thing a person does towards saving the earth will contribute in big or small amounts. We must learn that 1% effort is better than no effort. Pledge to take care of Mother Nature and speak up about global warming.

Global warming isn’t a prediction, it is happening! A person denying it or unaware of it is in the most simple terms complicit. Do we have another planet to live on? Unfortunately, we have been bestowed with this one planet only that can sustain life yet over the years we have turned a blind eye to the plight it is in. Global warming is not an abstract concept but a global phenomenon occurring ever so slowly even at this moment. Global Warming is a phenomenon that is occurring every minute resulting in a gradual increase in the Earth’s overall climate. Brought about by greenhouse gases that trap the solar radiation in the atmosphere, global warming can change the entire map of the earth, displacing areas, flooding many countries and destroying multiple lifeforms. Extreme weather is a direct consequence of global warming but it is not an exhaustive consequence. There are virtually limitless effects of global warming which are all harmful to life on earth. The sea level is increasing by 0.12 inches per year worldwide. This is happening because of the melting of polar ice caps because of global warming. This has increased the frequency of floods in many lowland areas and has caused damage to coral reefs. The Arctic is one of the worst-hit areas affected by global warming. Air quality has been adversely affected and the acidity of the seawater has also increased causing severe damage to marine life forms. Severe natural disasters are brought about by global warming which has had dire effects on life and property. As long as mankind produces greenhouse gases, global warming will continue to accelerate. The consequences are felt at a much smaller scale which will increase to become drastic shortly. The power to save the day lies in the hands of humans, the need is to seize the day. Energy consumption should be reduced on an individual basis. Fuel-efficient cars and other electronics should be encouraged to reduce the wastage of energy sources. This will also improve air quality and reduce the concentration of greenhouse gases in the atmosphere. Global warming is an evil which can only be defeated when fought together. It is better late than never. If we take steps today, we will have a much brighter future tomorrow. Global warming is the bane of our existence and various policies have come up worldwide to fight it but that is not enough. The actual difference is made when we work at an individual level to fight it. Understanding its importance now is crucial before it becomes an irrevocable mistake. Exterminating global warming is of utmost importance and everyone is as responsible for it as the next.  

Students in grades 1-3 can benefit from this kind of speech since it gives them a clear understanding of the issue in an accessible manner.

• Although global warming is not a new occurrence and has been a worry since before civilization, the danger is only getting worse over time.
• The average global temperature is rising as a result of pollution and damage to the natural systems that control the climate, including the air, water, and land.
• Population growth and people’s desire to live comfortably are the main causes of pollution.
• The primary sources include carbon emissions from the combustion of fossil fuels, factories, cars, trains, and other transportation, as well as from the coal industry.
• When these dangerous pollutants are discharged into the atmosphere, protective layers like ozone begin to erode, allowing dangerous solar rays to enter the atmosphere and causing a temperature rise.
• Because of the disastrous consequences of global warming, the threat has increased.
• This causes unnatural effects like the melting of glaciers, the rise in sea level, hurricanes, droughts, and floods, which alters the climate and upsets everything.
• Changes in rainfall patterns have only made agricultural lands and hence the vegetation worse.
• Using renewable energy sources, such as solar or wind, for power and other requirements can help us slow down the effects of climate change.
• To protect the environment and our natural resources, we must begin living sustainably.

Various factors lead to global warming. These days people have become so careless and selfish that they mainly focus on their growth and development. They tend to ignore nature’s need for love and care. Enlisted are the various causes of Global Warming:

• Industrial Activities : Industrial Activities lead to the vast usage of fossil fuels for the production of energy. These fossil fuels release carbon dioxide into the atmosphere, which leads to global warming. This energy is used for heat and electricity, transportation, industrial activities, agriculture, oil and gas production, etc.
• Agricultural Activities : The activity which provides every living thing with food is the one that leads to climate change, i.e., global warming. Agricultural activities use harmful commercial fertilizers that reap nitrous oxide, the most potent greenhouse gas. Methane is the other potent greenhouse gas that comes from the decomposition of waste, burning biomass, digestive systems of livestock, and numerous natural sources.
• Oil Drilling : Residuals from oil drilling release carbon dioxide. The processing of these fossil fuels and their distribution leads to methane production, a harmful greenhouse gas.
• Garbage : A recent study shows that 18 per cent of methane gas comes from wastage and its treatment. This methane gas leads to harmful conditions, i.e., global warming.

• Afforestation : Every individual should take up an oath to plant at least five trees a year. This will lead to an increase in the number of trees, ultimately reducing the overall temperature.
• Reduce, Reuse and Recycle : We should focus on reducing the use of fossil fuels and other products, which lead to the production of harmful gases. Reusing means repetitive use of a single product. We must focus on reusing products to omit the disposing procedure, which leads to the production of harmful greenhouse gases. One must also focus on recycling paper, glass, newspaper, etc., which can reduce carbon dioxide production, ultimately reducing global warming.
• Reduce Hot Water Use : We should reduce the unnecessary use of hot water that leads to the production of carbon dioxide. A recent study shows that high hot water usage leads to an approximate output of 350 pounds of carbon dioxide.
• Buy Better Bulbs : It’s observed that traditional bulbs consume more energy as compared to LED bulbs. LED bulbs approximately conserve 80 per cent of the energy that might get wasted using traditional ones. So, one must shift to efficient and energy-conserving bulbs, which will ultimately help reduce global warming.

The three main causes of global warming are – burning fossil fuels, deforestation and agricultural activities.

Some of the ways through which we can stop global warming are – driving less, recycling more, planting trees, replacing regular bulbs with CFL ones, avoiding products with a lot of packaging, etc.

Climate change affects human health as it depletes the water and air quality, leads to extreme weather, increases the pace at which certain diseases spread, etc.

Mother Earth is facing the consequences of our careless actions. It is high time now that we act and protect the environment. A few decades ago, afforestation, using renewable sources, etc., was just an option, but today, these have become a necessity. If we do not change and move towards a more sustainable growth model, this planet that we all share will be significantly affected, and life, as we know it today, may perish. Let’s take a pledge to conserve and restore the beauty of our planet Earth. For more such informative content, follow Leverage Edu !

Can We Engineer Our Way Out of the Climate Crisis?

On a windswept Icelandic plateau, an international team of engineers and executives is powering up an innovative machine designed to alter the very composition of Earth’s atmosphere.

If all goes as planned, the enormous vacuum will soon be sucking up vast quantities of air, stripping out carbon dioxide and then locking away those greenhouse gases deep underground in ancient stone — greenhouse gases that would otherwise continue heating up the globe.

Just a few years ago, technologies like these, that attempt to re-engineer the natural environment, were on the scientific fringe. They were too expensive, too impractical, too sci-fi. But with the dangers from climate change worsening, and the world failing to meet its goals of slashing greenhouse gas emissions, they are quickly moving to the mainstream among both scientists and investors, despite questions about their effectiveness and safety.

First in a series on the risky ways humans are starting to manipulate nature to fight climate change. Once science fiction, today these ideas are becoming reality.

Researchers are studying ways to block some of the sun’s radiation. They are testing whether adding iron to the ocean could carry carbon dioxide to the sea floor. They are hatching plans to build giant parasols in space . And with massive facilities like the one in Iceland, they are seeking to reduce the concentration of carbon dioxide in the air.

As the scale and urgency of the climate crisis has crystallized, “people have woken up and are looking to see if there’s any miraculous deus ex machina that can help,” said Al Gore, the former vice president.

Since the dawn of the industrial age, humans have pumped huge volumes of heat-trapping gases into the atmosphere in pursuit of industry and advancement. It amounted to a remaking of the planet’s delicately balanced atmosphere that today has transformed the world, intensifying heat, worsening droughts and storms and threatening human progress.

As the risks became clearer, political and corporate leaders pledged to keep global average temperatures to no more than 1.5 degrees Celsius higher than before the Industrial Revolution . But for several months last year, the world briefly passed that symbolic threshold, sooner than many scientists expected.

Global temperatures are now expected to rise as much as 4 degrees Celsius, or more than 7 degrees Fahrenheit, by the end of the century. That has given new weight to what some people call geoengineering, though that term has become so contentious its proponents now prefer the term “climate interventions.” The hope is that taking steps like these might buy some time at a moment when energy consumption is on the rise, and the world isn’t quitting fossil fuels fast enough.

Many of the projects are controversial. A plant similar to the one in Iceland, but far larger, is being built in Texas by Occidental Petroleum, the giant oil company. Occidental intends to use some of the carbon dioxide it captures to extract even more oil, the burning of which is one of the main causes of the climate crisis in the first place.

Some critics say that other types of interventions could open up a Pandora’s box of new problems by scrambling weather patterns or amplifying human suffering through unintended consequences. In effect they are asking: Should humans be experimenting with the environment in this way? Do we know enough to understand the risks?

“We need more information so we can make these decisions in the future,” said Alan Robock, a professor of atmospheric science at Rutgers University. “Which is riskier: to do it, or not to do it?”

Others argue that fanciful or costly technologies will simply waste resources and time, or lull people with the false idea that it will be possible to slow global warming without phasing out fossil fuels.

There is also the risk of rogue actors barreling ahead with their own efforts to change the climate. Already, Mexico has banned what’s known as solar radiation modification after a start-up from California released sulfur dioxide into the atmosphere without permission.

And then there is the fact that, because these technologies are so new, there is relatively little regulation governing them.

“There are these much bigger questions around who decides how is this is all coordinated over time,” said Marion Hourdequin, a professor of environmental philosophy at Colorado College. “We don’t have a great track record of sustained global cooperation.”

With a subzero wind whipping down from the fjords, Edda Aradottir trudged through fresh snow to inspect the direct air capture plant in Iceland.

Ms. Aradottir is the chief executive of Carbfix, an Icelandic company that is working with the Swiss start-up that built the plant, Climeworks. Known as Mammoth, the project is a technological accomplishment, powered by clean geothermal energy and capable of capturing up to 36,000 metric tons of carbon dioxide per year and pumping it down into the bedrock.

That is just one one-millionth of annual global emissions. But unlike trees, which can be cut down or catch fire, Climeworks promises to store that carbon dioxide forever.

Inside a series of bunkerlike buildings, dozens of huge fans suck air into bins that contain chemical pellets that absorb carbon dioxide, then release the gas when they are heated up. The carbon dioxide is then mixed with water and pumped more than a mile below the surface, where extreme pressure turns it into a solid in a matter of years, a process known as “mineralization.” In effect, the gas becomes part of the rock.

“Over 99 percent of the carbon on Earth is already stored in rocks in the form of minerals,” Ms. Aradottir said. “Naturally, it happens over geologic time scales. We’re speeding it up.”

When Mammoth is turned on in the coming weeks, it will be the largest such facility in the world, even though the amount of carbon it can absorb is still just a drop in the bucket. Global carbon dioxide emissions hit an all-time high of 36 billion metric tons last year.

The Occidental plant, being built near Odessa, Texas, and known as Stratos, will be more than 10 times more powerful than Mammoth, powered by solar energy, and have the potential to capture and sequester 500,000 metric tons of carbon dioxide per year.

It uses a different process to extract carbon dioxide from the air, though the goal is the same: Most of it will be locked away deep underground. But at least some of the carbon dioxide, Occidental says, will also be used to extract more oil.

In that process, carbon dioxide is pumped into the ground to force out oil that might otherwise be too difficult to reach. Techniques like this have made Occidental a company worth more than $50 billion and helped send American crude production to a new high in recent years.

Of course, it is the world’s reliance on the burning of oil and other fossil fuels that has so dangerously sent carbon dioxide levels soaring. In the atmosphere, carbon dioxide acts as a blanket, trapping the sun’s heat and warming the world.

Today, Occidental says it is trying to become a “carbon management” company as well as an oil producer. Last year, it paid $1.1 billion for a start-up called Carbon Engineering that had developed a way to soak up carbon dioxide from the air, and began building the Stratos project. Today, what was a barren plot of dirt less than 12 months ago is a bustling construction site.

“It’s like the Apollo missions at NASA,” said Richard Jackson, who oversees carbon management and domestic oil operations at Occidental. “We’re trying to move as quickly as we can.”

In coming years, Occidental said it planned to build 100 facilities, each capable of capturing 1 million metric tons of carbon dioxide a year. It has struck up a financial partnership with BlackRock, the world’s largest asset manager, and made a deal to develop direct air capture plants with Adnoc, the United Arab Emirates’ state oil company.

In South Texas, it is planning to build 30 of the plants on the King Ranch, funded in part by $1.2 billion the Biden administration last year awarded to direct air capture projects .

Climeworks also has aggressive expansion plans. It secured a portion of the White House funds for a direct air capture plant in Louisiana, is working with a group of Kenyan entrepreneurs to build a large facility outside Nairobi and has plans to construct plants in Canada and other countries in Europe.

Driving the construction boom is the desire of many corporations to reduce their effect on global warming. Over the past decade, hundreds of multinational corporations have pledged to become carbon neutral by 2040. Rather than phasing out fossil fuels to meet those goals, most companies are finding that they have to pay for carbon credits, which can be acquired by preserving forests, supporting renewable energy projects or paying for carbon sequestration.

Microsoft, JPMorgan and UBS are some of the big companies that have signed long term agreements to buy credits from Climeworks. Amazon, AT&T and the Houston Astros are among those signed up with Occidental.

Bill Gates, the Microsoft co-founder, said last year that he was the largest individual customer of Climeworks, paying the company $10 million each year to offset his sizable carbon footprint.

Yet the grand plans envisioned by direct air capture companies, with hundreds of plants built in the years ahead, are predicated on a market that does not yet exist. Only a handful of big companies have so far proved willing to voluntarily spend millions of dollars on direct air capture credits, and there is no guarantee that the rest of the corporate world will follow suit anytime soon.

Even if more companies do decide to start offsetting their emissions, there are cheaper ways to do so, including by preserving forests and paying for renewable energy. For example, it currently costs between $500 and $1,000 to capture a metric ton of carbon dioxide with direct air capture, compared with just $10 to $30 per ton for most carbon credits today .

“ It’s very expensive,” said Mr. Robock. “And so it’s not going to be a solution in the short term or the long term.”

Still, the business world is bullish. Boston Consulting Group expects more companies to begin buying credits to pay for carbon dioxide removal, and more governments to encourage that buying. In the United States and Europe, governments have started subsidizing the construction of the plants. By 2040, BCG expects the market for carbon dioxide removal technologies could grow from less than $10 billion today to as much as $135 billion.

“Companies will face a rising price on carbon and regulatory pressures that will make them feel compelled to do this,” said Rich Lesser, the global chair of BCG.

Although the direct air capture market is still in its infancy, it already has vociferous detractors in academia, activist circles and beyond.

Some say it is little more than a ploy by oil and gas companies to prolong the very industries that are responsible for creating global warming. They point to the extensive evidence that fossil fuel interests for years worked to play down public awareness of climate change, and the fact that some of the captured carbon will be used for additional oil production.

Those concerns were magnified when Vicki Hollub, Occidental’s chief executive, last year said direct air capture could “preserve our industry.” She added, “This gives our industry a license to continue to operate for the 60, 70, 80 years that I think it’s going to be very much needed.”

Scientists say an urgent transition away from fossil fuels is necessary to avoid extreme global temperature increases. Last year, nearly 200 countries agreed to begin phasing out oil, coal and gas.

“This is a new wave of denial, deception and delay,” said Lili Fuhr, director of the fossil economy program at the Center for International Environmental Law. “You have the fossil fuel industry trying to say we can engineer our way out of this without any major changes to business as usual.”

A related line of reasoning holds that the enormous amounts of clean energy needed to power direct air capture plants would be better used powering homes and businesses, thereby displacing fossil fuels such as natural gas and coal that still provide much of the world’s electricity.

Ms. Fuhr added that the costs remained high in spite of a growing raft of government support, including a tax credit in the United States worth $180 for every metric ton of carbon dioxide that is captured and stored, a subsidy that is likely to significantly lower Occidental’s tax bill in the years ahead. “The industry has been successful in capturing subsidies, just not carbon,” she said.

And then there is the fact that even if Occidental and Climeworks make good on their ambitions to build hundreds of new plants in the coming years, they would still not come close to capturing even 1 percent of current annual global emissions.

Mark Z. Jacobson, a professor of civil and environmental engineering at Stanford University, said climate interventions in general, and carbon capture in particular, were dangerous distractions from the more urgent work of rapidly reducing the use of fossil fuels.

“There are many solutions that are just not helpful at all, that do not help an iota for climate and don’t help an iota for air pollution,” he said. “Among these are direct air capture.”

Proponents of the technology say that with fossil fuel emissions continuing to rise, the world is fast approaching the moment when any and all solutions to abate global warming should be on the table.

At the least, direct air capture has a role to play, they say, because there might always be at least some greenhouse gases being produced in the future, even if the vast majority of emissions are successfully eliminated. Sucking that carbon dioxide out of the air will be valuable, the argument goes.

But in the longer term, many scientists believe it will be necessary to go further and actually try to remove some of the excess carbon dioxide that has dangerously accumulated over the centuries. Proponents of direct air capture say their technology is suited for such a herculean task.

“No one is arguing you could solve all our carbon emissions with this,” Mr. Lesser said. “But it could be a meaningful part of solving a huge problem.”

The past year’s record temperatures, warming oceans and megafires are all evidence of a deeply uncomfortable reality: We’ve already been manipulating the planet for the past couple hundred years. In less time than it takes a redwood tree to reach its full height, humans have added enough carbon dioxide to the atmosphere to scramble weather patterns, melt glaciers and wipe out coral reefs.

Viewed this way, today’s attempts to slow down or even reverse the warming can be seen as efforts to undo the changes that have already taken place. Whether or not humans can succeed in this most ambitious feat is unclear. It is among the most consequential problems our species has faced.

Yet as people begin to deliberately tinker with the climate in new ways, there are profound questions that are only beginning to be contemplated. If the current extreme weather and temperature rise came about inadvertently, as the unintentional consequence of human development, what might happen when we begin actively trying to control the planet’s atmosphere?

“It’s true that we have been altering the climate through greenhouse gas emissions for centuries now,” said Ms. Hourdequin of Colorado College. “But trying to intentionally manage the climate through geoengineering would be a distinctive endeavor, quite different than the kind of haphazard interference that we’ve engaged in thus far.”
