Essay on Global Warming in English (100,150, 200, 250, 300, 500 Words)

Global warming means the Earth is getting hotter. This happens because of things like pollution from cars and factories. These pollutants are called greenhouse gases, and they make the Earth's air trap more heat from the sun. One major greenhouse gas is carbon dioxide, which comes from burning fossil fuels like coal, oil, and gas. When trees are cut down and forests disappear, that's bad too, because trees help clean the air.

Because of global warming, some big problems are happening. Ice at the North and South Poles is melting, which causes the sea levels to rise. When the sea level goes up, it can flood coastal areas, making it hard for people to live there. Also, the Earth's weather is getting crazy. There are more hurricanes, droughts, and floods. These extreme weather events can be dangerous and damage homes and farms.

But don't worry! People all over the world are working to stop global warming. They use clean and renewable energy sources like the sun and wind instead of burning fossil fuels. They also make agreements like the Paris Agreement and the Kyoto Protocol to help reduce pollution. These agreements are like promises between countries to protect the planet.

Understanding global warming is important because it harms the environment and makes life harder for everyone. We need to take care of our planet by using clean energy and protecting forests. It's like being a good friend to the Earth. So, let's all work together to keep the Earth cool and safe for the future.

Why is the Essay on Global Warming Important for Your Exams? 

The essay on global warming is important for your exams for several reasons. First, it helps you learn about a critical issue that affects our planet. Global warming is the increase in Earth's temperature due to human activities like burning fossil fuels and deforestation. Knowing about this topic is essential because it's a significant environmental problem that impacts all of us.

Second, writing an essay on global warming can improve your research and writing skills. It teaches you how to gather information, organize your thoughts, and present them in a clear and structured way. These skills are valuable for your education and future career.

Fourth, addressing global warming is a global concern. International agreements like the Paris Agreement involve many countries working together to combat climate change. Knowing about these agreements and the actions taken by different nations can help you understand how the world is coming together to solve a shared problem.

Fifth, discussing global warming in your exams can demonstrate your awareness and concern for the environment. It shows that you're informed about the challenges our planet faces and that you're engaged in finding solutions.

Long and Short Essay on Global Warming

Essay on global warming 1 (100 words) .

Global warming is a big problem worldwide. Earth is getting hotter because it traps the Sun's heat, and there's too much carbon dioxide in the air. This is causing more and more problems for people. It's a serious issue that needs our attention. We must understand what causes it and how it harms us. We also need to find ways to fix it. We should work together to save our planet and make it a better place to live.

Essay on Global Warming 2 (150 words) 

Global warming is a major issue affecting our planet. It's making the Earth's surface temperature go up. Experts say that in the next 50 to 100 years, the temperature will rise a lot, causing big problems for everyone. The main reason for this is the increase in carbon dioxide in the air.

Carbon dioxide levels go up when we use things like coal and oil for energy, and when we cut down trees (deforestation). Trees are important because they absorb carbon dioxide and give us oxygen. When there are fewer trees, carbon dioxide levels increase.

Higher temperatures cause many problems like hotter oceans, melting glaciers, floods, stronger storms, and more diseases. It's a serious issue that affects us all. To tackle it, we need to use cleaner energy sources and protect our forests. Working together, we can make a difference and keep our planet safe for the future.

Essay on Global Warming 3 (200 words) 

Global warming is when the Earth's temperature keeps going up. This happens because of things we do without even noticing, like burning fossil fuels and using too much electricity. Global warming is a big problem for our planet, and it's getting worse every day. It's like a threat that's making life harder on Earth.

To fix global warming, we first need to understand what's causing it. One of the main reasons is the extra carbon dioxide (CO2) in the air. This comes from things like cutting down trees and using coal, oil, and gas for energy. It's also from burning gasoline in cars. All of this makes the Earth's temperature rise.

When the Earth gets hotter, it causes problems like rising sea levels, floods, storms, and even more diseases. It's a big issue, and it affects all of us. We can't blame just one person or country for this. Everyone is a part of the problem, so we all need to work together to solve it.

We need to be aware of global warming and do our best to stop it. This means using cleaner energy sources and being more careful with our planet. It's a team effort, and if we all pitch in, we can make a difference and make the Earth a better place to live.

Essay on Global Warming 4 (250 words) 

Global warming is a serious and ongoing increase in the Earth's temperature. It's a huge problem worldwide and is mainly caused by the rise in carbon dioxide and other greenhouse gases in our atmosphere. If we don't take immediate action as a global community, it could lead to catastrophic consequences, even threatening life on Earth.

The effects of global warming are becoming more dangerous every day. It's responsible for rising sea levels, floods, erratic weather patterns, storms, epidemics, food shortages, and loss of life. To combat this issue, we need to raise awareness at the individual level. People must understand what global warming is, what causes it, and the harm it brings. By making people worldwide aware, we can work together to restore the Earth's natural balance and ensure life can continue as usual.

To address global warming, we should reduce our carbon dioxide emissions. This means using less oil, coal, and gas, protecting trees (as they absorb carbon dioxide and provide oxygen), and using electricity more wisely. Small changes in our daily lives, practiced worldwide, can make a big difference in lessening the impact of global warming and ultimately stopping it. Everyone needs to take responsibility and contribute to a safer, healthier planet for current and future generations.

Essay on Global Warming 5 (300 words) 

Global warming is the gradual heating of the Earth's surface due to an increase in carbon dioxide gas in the environment. It's a major issue that requires worldwide action. As the Earth's temperature steadily rises, it poses various threats and disrupts the balance of nature. This temperature rise brings about lasting changes in our climate, affecting the environment.

The increase in carbon dioxide (CO2) levels has far-reaching consequences. It leads to heatwaves, sudden and powerful storms, unpredictable cyclones, damage to the ozone layer, floods, heavy rainfall, droughts, food shortages, diseases, and even loss of life. This problem is largely driven by the continuous burning of fossil fuels, the use of fertilizers, deforestation, excessive electricity consumption, and certain gases used in refrigeration. If we don't take action to control CO2 emissions, the harmful effects of global warming are predicted to worsen by 2020.

The increased CO2 levels cause a phenomenon known as the greenhouse effect. Greenhouse gases like water vapor, CO2, methane, and ozone absorb heat energy, which is then radiated in all directions, including back toward the Earth's surface. This results in the Earth's surface warming up, contributing to global warming.

To combat the life-threatening effects of global warming, we must change our habits. We need to stop activities that increase CO2 and other greenhouse gases, leading to the greenhouse effect and global warming. This includes ending deforestation, reducing electricity consumption, and halting the burning of wood and other fossil fuels. These are critical steps to ensure a healthier and safer planet for ourselves and future generations. By working together and making these changes, we can address the global warming crisis and protect our world.

Essay on Global Warming 6 (500 words) 

Global warming is an enormous environmental problem that we must address urgently and permanently. It refers to the continuous and gradual increase in the Earth's surface temperature. This issue requires global cooperation and discussion to mitigate its effects, as it has already disrupted the delicate balance of nature, impacted biodiversity, and significantly altered our planet's climate over several decades.

The primary culprits behind global warming are greenhouse gases, particularly carbon dioxide (CO2) and methane. These gases trap heat in the Earth's atmosphere, causing a rise in temperatures. This, in turn, leads to rising sea levels, melting ice caps and glaciers, and unpredictable climate changes, all of which pose serious threats to life on our planet. The demand for an improved standard of living has driven an increase in atmospheric greenhouse gas concentrations, especially since the mid-20th century.

Statistical data reveal alarming trends, with years like 1983, 1987, 1988, 1989, and 1991 being recorded as the warmest six years of the past century. Such an increase in global warming has led to unforeseen natural disasters, including floods, cyclones, tsunamis, droughts, landslides, ice melting, food shortages, epidemic diseases, and even loss of life. These events disrupt the natural balance of our planet and signal a potential threat to life as we know it.

The global warming process intensifies as more water evaporates from the Earth's surface into the atmosphere. This excess water vapor further contributes to the greenhouse effect, causing temperatures to rise. Additionally, human activities such as the burning of fossil fuels, the use of fertilizers, and the emission of gases like chlorofluorocarbons (CFCs), tropospheric ozone, and nitrous oxide are also responsible for global warming.

The root causes of these problems can be traced back to technological advancements, population growth, an increasing demand for industrial expansion, deforestation, and the prioritization of urbanization. As our population continues to grow, we consume more resources, leading to higher emissions of greenhouse gases and a depletion of the Earth's natural resources.

To address global warming and its devastating effects, we must take immediate and collective action. The time for inaction has long passed. We must prioritize sustainability, renewable energy sources, afforestation, and reforestation to reduce CO2 levels and mitigate the impact of global warming. Additionally, responsible and conscious consumption, efficient energy use, and reducing waste are critical steps in the fight against this crisis.

Education and awareness are also key. People need to understand the causes and consequences of global warming, prompting a change in behavior and the adoption of more environmentally friendly practices. Governments, businesses, and individuals must work together to protect our planet and secure a sustainable future for generations to come. The solution to global warming requires a global commitment to change our way of life and preserve the Earth for future generations.

Essay on Global Warming

The last few decades have been monumental when it comes to technological development. Humans have developed systems and machines that make our lives easier. Especially during the early modern period from the early 16th century to as far as the late 18the century, also commonly referred to as “The Scientific Revolution” or “The Enlightenment”, modern technology leapt ahead in development in such a short time frame compared to all of history.

However, with the development of society, there has been a severe detriment to the quality of Earth’s environment. One of the most massive threats to the condition of the planet is climate change. Inadequate research and reckless misuse of natural resources are some of the core reasons for the deteriorating condition of the planet.

To understand the concept of Global Warming and its causes and effects, we need to take an in-depth look into many factors that affect the temperature of the planet and what that means for the future of the world. Here is an objective look at the topic of Global Warming and other important related topics.

What is Climate Change?

Ever since the industrial and scientific revolution, Earth is slowly being used up for its resources. Moreover, the onset of the exponential increase in the world’s population is also very taxing on the environment. 

Simply put, as the need for consumption of the population increases, both the utilisation of natural resources and the waste generated from the use of said resources have also increased massively. 

One of the main results of this over the many years has become climate change. Climate change is not just the rise or fall of temperature of different areas of the world; it is also a change in the rain cycles, wind patterns, cyclone frequencies, sea levels, etc. It affects all major life groups on the planet in some way or the other.  

What is Global Warming?

Global Warming is often considered an effect of Climate change. Global Warming is the rapid increase in the temperature of the Earth’s environment that is causing many life-threatening issues to arise.

Global Warming is a dangerous effect on our environment that we are facing these days. Rapid industrialization, increase in the population growth and pollution are causing a rise in Global Warming. Global Warming refers to the increase in the average temperature of the earth's surface during the last century. One of the reasons why Global Warming is dangerous is because it disturbs the overall ecology of the planet. This results in floods, famine, cyclones and other issues. There are many causes and results of this warming and is a danger for the existence of life on earth.

The sign of Global Warming is already visible with many natural phenomena happening around globally, affecting each living species.

Here is some data that can help to give a more precise understanding of the reality of Global Warming in the last few years:

On average, the world’s temperature is about 1.5°C higher than during the start of the industrial revolution in the late 1700s. That may not seem a lot to you, but that is an average estimate. This number is only increasing. Many parts of the world face far more severe changes in temperature that affect the planet’s overall health.

In 1950, the world’s CO 2 emissions were at 6 billion tonnes which had quadrupled in volume until 1990, just 40 years later to 22 billion tonnes. Not only that, unchecked CO 2 emissions today have reached a whopping 35 billion tonnes.

The most evident causes of Global Warming are industrialization, urbanization, deforestation, and sophisticated human activities. These human activities have led to an increase in the emission of Greenhouse Gases, including CO₂, Nitrous Oxide, Methane, and others.

Causes of Global Warming

A variety of reasons causes Global Warming. Some of which can be controlled personally by individuals but others are only expected to be solved by communities and the world leaders and activists at the global level.

Many scientists believe the main four reasons for Global Warming, according to recent studies, are:

Greenhouse gases

Deforestation

Per capita carbon emissions

Global Warming is certainly an alarming situation, which is causing a significant impact on life existence. Extreme Global Warming is resulting in natural calamities, which is quite evident happening around. One of the reasons behind Global Warming is the extreme release of greenhouse gases stuck on the earth surface, resulting in the temperature increase.

Similarly, volcanoes are also leading to Global Warming because they spew too much CO₂ in the air. One of the significant causes behind Global Warming is the increase in the population. This increase in the population also results in air pollution. Automobiles release a lot of CO₂, which remains stuck in the earth.

This increase in the population is also leading to deforestation, which further results in Global Warming. More and more trees are being cut, increasing the concentration of CO₂.

The greenhouse is the natural process where the sunlight passes through the area, thus warming the earth's surface. The earth surface releases energy in the form of heat in the atmosphere maintaining the balance with the incoming energy. Global Warming depletes the ozone layer leading to the doom's day.

There is a clear indication that the increase in Global Warming will lead to the complete extinction of life from the earth surface.

Solution for Global Warming

Global Warming can not be blamed on individuals; however, it can be tackled and maintained from worsening starting at the individual level. Of course, industries and multinational conglomerates have higher carbon emissions levels than an average citizen. Still, activism and community effort are the only feasible ways to control the worsening state of Global Warming.

Additionally, at the state or government level, world leaders need to create concrete plans and step programmes to ensure that no further harm is being caused to the environment in general. 

Although we are almost late in slowing down the Global Warming rate, it is crucial to find the right solution. From individuals to governments, everyone has to work upon a solution for Global Warming. Controlling pollution, population and use of natural resources are some of the factors to consider. Switching over to the electric and hybrid car is the best way to bring down the carbon dioxide.

As a citizen, it is best to switch over to the hybrid car and to use public transport. This will reduce pollution and congestion. Another significant contribution you can make is to minimize the use of plastic. Plastic is the primary cause of Global Warming taking years to recycle.

Deforestation is another thing to consider that will help in controlling Global Warming. Planting of more trees should be encouraged to make the environment go green.

Industrialization should be under certain norms. The building of industries should be banned in green zones affecting plants and species. Hefty penalties should be levied on such sectors contributing towards Global Warming.

Effects of Global Warming

Global Warming is a real problem that many want to prove as a hoax for their political benefit. However, as aware citizens of the world, we must make sure only the truth is presented in the media.

Various parts of the environment, both flora and fauna, are directly adversely affected by the damages caused by Global Warming. Wildlife being in danger is ultimately a serious threat to the survival of humanity as we know it and its future.

The effect of Global Warming is widely seen in this decade. Glacier retreat and arctic shrinkage are the two common phenomena seen. Glaciers are melting in a fast way. These are pure examples of climate change.

Rise in sea level is another significant effect of Global Warming. This sea-level rise is leading to floods in low-lying areas. Extreme weather conditions are witnessed in many countries. Unseasonal rainfall, extreme heat and cold, wildfires and others are common every year. The number of these cases is increasing. This will indeed imbalance the ecosystem bringing the result of the extinction of species.

Similarly, marine life is also widely getting affected due to the increase in Global Warming. This is resulting in the death of marine species and other issues. Moreover, changes are expected in coral reefs, which are going to face the end in coming years.

These effects will take a steep rise in coming years, bringing the expansion of species to a halt. Moreover, humans too will witness the negative impact of Global Warming in the end.

FAQs on Global Warming Essay

1. What Global Warming will Cause?

Global warming will have a massive impact on our earth in the end. Flood, extreme weather conditions, famine, wildfire and many more will be the result. There will be hotter days, which will also increase the wildfire and famine. In the past years, many meteorological bureaus have added purple and magenta to the forecast.

Another impact of global warming will be rising sea levels. Increased ocean temperatures will lead to the melting of glaciers and ice caps. Increase in the sea level will lead to floods in many low-lying areas.

The overall ecosystem of nature will be an imbalance. This will affect nature in the long-term.

2. Why Does Global Warming Happen?

There are many reasons for the cause of global warming. There are certain gases in the atmosphere called greenhouse gases. The energy then radiates from the surface; the greenhouse gases trap longwave radiation. We humans have added to the atmospheric blanket of greenhouse affecting the living species. Warming of air, oceans, and land is how global warming happens.

Deep warming

Even if we ‘solve’ global warming, we face an older, slower problem. waste heat could radically alter earth’s future.

by Mark Buchanan   + BIO

The world will be transformed. By 2050, we will be driving electric cars and flying in aircraft running on synthetic fuels produced through solar and wind energy. New energy-efficient technologies, most likely harnessing artificial intelligence, will dominate nearly all human activities from farming to heavy industry. The fossil fuel industry will be in the final stages of a terminal decline. Nuclear fusion and other new energy sources may have become widespread. Perhaps our planet will even be orbited by massive solar arrays capturing cosmic energy from sunlight and generating seemingly endless energy for all our needs.

That is one possible future for humanity. It’s an optimistic view of how radical changes to energy production might help us slow or avoid the worst outcomes of global warming. In a report from 1965, scientists from the US government warned that our ongoing use of fossil fuels would cause global warming with potentially disastrous consequences for Earth’s climate. The report, one of the first government-produced documents to predict a major crisis caused by humanity’s large-scale activities, noted that the likely consequences would include higher global temperatures, the melting of the ice caps and rising sea levels. ‘Through his worldwide industrial civilisation,’ the report concluded, ‘Man is unwittingly conducting a vast geophysical experiment’ – an experiment with a highly uncertain outcome, but clear and important risks for life on Earth.

Since then, we’ve dithered and doubted and argued about what to do, but still have not managed to take serious action to reduce greenhouse gas emissions, which continue to rise. Governments around the planet have promised to phase out emissions in the coming decades and transition to ‘green energy’. But global temperatures may be rising faster than we expected: some climate scientists worry that rapid rises could create new problems and positive feedback loops that may accelerate climate destabilisation and make parts of the world uninhabitable long before a hoped-for transition is possible.

Despite this bleak vision of the future, there are reasons for optimists to hope due to progress on cleaner sources of renewable energy, especially solar power. Around 2010, solar energy generation accounted for less than 1 per cent of the electricity generated by humanity. But experts believe that, by 2027, due to falling costs, better technology and exponential growth in new installations, solar power will become the largest global energy source for producing electricity. If progress on renewables continues, we might find a way to resolve the warming problem linked to greenhouse gas emissions. By 2050, large-scale societal and ecological changes might have helped us avoid the worst consequences of our extensive use of fossil fuels.

It’s a momentous challenge. And it won’t be easy. But this story of transformation only hints at the true depth of the future problems humanity will confront in managing our energy use and its influence over our climate.

As scientists are gradually learning, even if we solve the immediate warming problem linked to the greenhouse effect, there’s another warming problem steadily growing beneath it. Let’s call it the ‘deep warming’ problem. This deeper problem also raises Earth’s surface temperature but, unlike global warming, it has nothing to do with greenhouse gases and our use of fossil fuels. It stems directly from our use of energy in all forms and our tendency to use more energy over time – a problem created by the inevitable waste heat that is generated whenever we use energy to do something. Yes, the world may well be transformed by 2050. Carbon dioxide levels may stabilise or fall thanks to advanced AI-assisted technologies that run on energy harvested from the sun and wind. And the fossil fuel industry may be taking its last breaths. But we will still face a deeper problem. That’s because ‘deep warming’ is not created by the release of greenhouse gases into the atmosphere. It’s a problem built into our relationship with energy itself.

F inding new ways to harness more energy has been a constant theme of human development. The evolution of humanity – from early modes of hunter-gathering to farming and industry – has involved large systematic increases in our per-capita energy use. The British historian and archaeologist Ian Morris estimates, in his book Foragers, Farmers, and Fossil Fuels: How Human Values Evolve (2015), that early human hunter-gatherers, living more than 10,000 years ago, ‘captured’ around 5,000 kcal per person per day by consuming food, burning fuel, making clothing, building shelter, or through other activities. Later, after we turned to farming and enlisted the energies of domesticated animals, we were able to harness as much as 30,000 kcal per day. In the late 17th century , the exploitation of coal and steam power marked another leap: by 1970, the use of fossil fuels allowed humans to consume some 230,000 kcal per person per day. (When we think about humanity writ large as ‘humans’, it’s important to acknowledge that the average person in the wealthiest nations consumes up to 100 times more energy than the average person in the poorest nations.) As the global population has risen and people have invented new energy-dependent technologies, our global energy use has continued to climb.

In many respects, this is great. We can now do more with less effort and achieve things that were unimaginable to the 17th-century inventors of steam engines, let alone to our hominin ancestors. We’ve made powerful mining machines, superfast trains, lasers for use in telecommunications and brain-imaging equipment. But these creations, while helping us, are also subtly heating the planet.

All the energy we humans use – to heat our homes, run our factories, propel our automobiles and aircraft, or to run our electronics – eventually ends up as heat in the environment. In the shorter term, most of the energy we use flows directly into the environment. It gets there through hot exhaust gases, friction between tires and roads, the noises generated by powerful engines, which spread out, dissipate, and eventually end up as heat. However, a small portion of the energy we use gets stored in physical changes, such as in new steel, plastic or concrete. It’s stored in our cities and technologies. In the longer term, as these materials break down, the energy stored inside also finds its way into the environment as heat. This is a direct consequence of the well-tested principles of thermodynamics.

Waste heat will pose a problem that is every bit as serious as global warming from greenhouse gases

In the early decades of the 21st century , this heat created by simply using energy, known as ‘waste heat’, is not so serious. It’s equivalent to roughly 2 per cent of the planetary heating imbalance caused by greenhouse gases – for now. But, with the passing of time, the problem is likely to get much more serious. That’s because humans have a historical tendency to consistently discover and produce things, creating entirely new technologies and industries in the process: domesticated animals for farming; railways and automobiles; global air travel and shipping; personal computers, the internet and mobile phones. The result of such activities is that we end up using more and more energy, despite improved energy efficiency in nearly every area of technology.

During the past two centuries at least (and likely for much longer), our yearly energy use has doubled roughly every 30 to 50 years . Our energy use seems to be growing exponentially, a trend that shows every sign of continuing. We keep finding new things to do and almost everything we invent requires more and more energy: consider the enormous energy demands of cryptocurrency mining or the accelerating energy requirements of AI.

If this historical trend continues, scientists estimate waste heat will pose a problem in roughly 150-200 years that is every bit as serious as the current problem of global warming from greenhouse gases. However, deep heating will be more pernicious as we won’t be able to avoid it by merely shifting from one kind energy to another. A profound problem will loom before us: can we set strict limits on all the energy we use? Can we reign in the seemingly inexorable expansion of our activities to avoid destroying our own environment?

Deep warming is a problem hiding beneath global warming, but one that will become prominent if and when we manage to solve the more pressing issue of greenhouse gases. It remains just out of sight, which might explain why scientists only became concerned about the ‘waste heat’ problem around 15 years ago.

O ne of the first people to describe the problem is the Harvard astrophysicist Eric Chaisson, who discussed the issue of waste heat in a paper titled ‘Long-Term Global Heating from Energy Usage’ (2008). He concluded that our technological society may be facing a fundamental limit to growth due to ‘unavoidable global heating … dictated solely by the second law of thermodynamics, a biogeophysical effect often ignored when estimating future planetary warming scenarios’. When I emailed Chaisson to learn more, he told me the history of his thinking on the problem:

It was on a night flight, Paris-Boston [circa] 2006, after a UNESCO meeting on the environment when it dawned on me that the IPCC were overlooking something. While others on the plane slept, I crunched some numbers literally on the back of an envelope … and then hoped I was wrong, that is, hoped that I was incorrect in thinking that the very act of using energy heats the air, however slightly now.

The transformation of energy into heat is among the most ubiquitous processes of physics

Chaisson drafted the idea up as a paper and sent it to an academic journal. Two anonymous reviewers were eager for it to be published. ‘A third tried his damnedest to kill it,’ Chaisson said, the reviewer claiming the findings were ‘irrelevant and distracting’. After it was finally published, the paper got some traction when it was covered by a journalist and ran as a feature story on the front page of The Boston Globe . The numbers Chaisson crunched, predictions of our mounting waste heat, were even run on a supercomputer at the US National Center for Atmospheric Research, by Mark Flanner, a professor of earth system science. Flanner, Chaisson suspected at the time, was likely ‘out to prove it wrong’. But, ‘after his machine crunched for many hours’, he saw the same results that Chaisson had written on the back of an envelope that night in the plane.

Around the same time, also in 2008, two engineers, Nick Cowern and Chihak Ahn, wrote a research paper entirely independent of Chaisson’s work, but with similar conclusions. This was how I first came across the problem. Cowern and Ahn’s study estimated the total amount of waste heat we’re currently releasing to the environment, and found that it is, right now, quite small. But, like Chaisson, they acknowledged that the problem would eventually become serious unless steps were taken to avoid it.

That’s some of the early history of thinking in this area. But these two papers, and a few other analyses since, point to the same unsettling conclusion: what I am calling ‘deep warming’ will be a big problem for humanity at some point in the not-too-distant future. The precise date is far from certain. It might be 150 years , or 400, or 800, but it’s in the relatively near future, not the distant future of, say, thousands or millions of years. This is our future.

T he transformation of energy into heat is among the most ubiquitous processes of physics. As cars drive down roads, trains roar along railways, planes cross the skies and industrial plants turn raw materials into refined products, energy gets turned into heat, which is the scientific word for energy stored in the disorganised motions of molecules at the microscopic level. As a plane flies from Paris to Boston, it burns fuel and thrusts hot gases into the air, generates lots of sound and stirs up contrails. These swirls of air give rise to swirls on smaller scales which in turn make smaller ones until the energy ultimately ends up lost in heat – the air is a little warmer than before, the molecules making it up moving about a little more vigorously. A similar process takes place when energy is used by the tiny electrical currents inside the microchips of computers, silently carrying out computations. Energy used always ends up as heat. Decades ago, research by the IBM physicist Rolf Landauer showed that a computation involving even a single computing bit will release a certain minimum amount of heat to the environment.

How this happens is described by the laws of thermodynamics, which were described in the mid-19th century by scientists including Sadi Carnot in France and Rudolf Clausius in Germany. Two key ‘laws’ summarise its main principles.

The first law of thermodynamics simply states that the total quantity of energy never changes but is conserved. Energy, in other words, never disappears, but only changes form. The energy initially stored in an aircraft’s fuel, for example, can be changed into the energetic motion of the plane. Turn on an electric heater, and energy initially held in electric currents gets turned into heat, which spreads into the air, walls and fabric of your house. The total energy remains the same, but it markedly changes form.

We’re generating waste heat all the time with everything we do

The second law of thermodynamics, equally important, is more subtle and states that, in natural processes, the transformation of energy always moves from more organised and useful forms to less organised and less useful forms. For an aircraft, the energy initially concentrated in jet fuel ends up dissipated in stirred-up winds, sounds and heat spread over vast areas of the atmosphere in a largely invisible way. It’s the same with the electric heater: the organised useful energy in the electric currents gets dissipated and spread into the low-grade warmth of the walls, then leaks into the outside air. Although the amount of energy remains the same, it gradually turns into less organised, less usable forms. The end point of the energy process produces waste heat. And we’re generating it all the time with everything we do.

Data on world energy consumption shows that, collectively, all humans on Earth are currently using about 170,000 terawatt-hours (TWh), which is a lot of energy in absolute terms – a terawatt-hour is the total energy consumed in one hour by any process using energy at a rate of 1 trillion watts. This huge number isn’t surprising, as it represents all the energy being used every day by the billions of cars and homes around the world, as well as by industry, farming, construction, air traffic and so on. But, in the early 21st century , the warming from this energy is still much less than the planetary heating due to greenhouse gases.

Concentrations of greenhouse gases such as CO 2 and methane are quite small, and only make a fractional difference to how much of the Sun’s energy gets trapped in the atmosphere, rather than making it back out to space. Even so, this fractional difference has a huge effect because the stream of energy arriving from the Sun to Earth is so large. Current estimates of this greenhouse energy imbalance come to around 0.87 W per square meter, which translates into a total energy figure about 50 times larger than our waste heat. That’s reassuring. But as Cowern and Ahn wrote in their 2008 paper, things aren’t likely to stay this way over time because our energy usage keeps rising. Unless, that is, we can find some radical way to break the trend of using ever more energy.

O ne common objection to the idea of the deep warming is to claim that the problem won’t really arise. ‘Don’t worry,’ someone might say, ‘with efficient technology, we’re going to find ways to stop using more energy; though we’ll end up doing more things in the future, we’ll use less energy.’ This may sound plausible at first, because we are indeed getting more efficient at using energy in most areas of technology. Our cars, appliances and laptops are all doing more with less energy. If efficiency keeps improving, perhaps we can learn to run these things with almost no energy at all? Not likely, because there are limits to energy efficiency.

Over the past few decades, the efficiency of heating in homes – including oil and gas furnaces, and boilers used to heat water – has increased from less than 50 per cent to well above 90 per cent of what is theoretically possible. That’s good news, but there’s not much more efficiency to be realised in basic heating. The efficiency of lighting has also vastly improved, with modern LED lighting turning something like 70 per cent of the applied electrical energy into light. We will gain some efficiencies as older lighting gets completely replaced by LEDs, but there’s not a lot of room left for future efficiency improvements. Similar efficiency limits arise in the growing or cooking of food; in the manufacturing of cars, bikes and electronic devices; in transportation, as we’re taken from place to place; in the running of search engines, translation software, GPT-4 or other large-language models.

Even if we made significant improvements in the efficiencies of these technologies, we will only have bought a little time. These changes won’t delay by much the date when deep warming becomes a problem we must reckon with.

Optimising efficiencies is just a temporary reprieve, not a radical change in our human future

As a thought experiment, suppose we could immediately improve the energy efficiency of everything we do by a factor of 10 – a fantastically optimistic proposal. That is, imagine the energy output of humans on Earth has been reduced 10 times , from 170,000 TWh to 17,000 TWh . If our energy use keeps expanding, doubling every 30-50 years or so (as it has for centuries), then a 10-fold increase in waste heat will happen in just over three doubling times, which is about 130 years : 17,000 TWh doubles to 34,000 TWh , which doubles to 68,000 TWh , which doubles to 136,000 TWh , and so on. All those improvements in energy efficiency would quickly evaporate. The date when deep warming hits would recede by 130 years or so, but not much more. Optimising efficiencies is just a temporary reprieve, not a radical change in our human future.

Improvements in energy efficiency can also have an inverse effect on our overall energy use. It’s easy to think that if we make a technology more efficient, we’ll then use less energy through the technology. But economists are deeply aware of a paradoxical effect known as ‘rebound’, whereby improved energy efficiency, by making the use of a technology cheaper, actually leads to more widespread use of that technology – and more energy use too. The classic example, as noted by the British economist William Stanley Jevons in his book The Coal Question (1865), is the invention of the steam engine. This new technology could extract energy from burning coal more efficiently, but it also made possible so many new applications that the use of coal increased. A recent study by economists suggests that, across the economy, such rebound effects might easily swallow at least 50 per cent of any efficiency gains in energy use. Something similar has already happened with LED lights, for which people have found thousands of new uses.

If gains in efficiency won’t buy us lots of time, how about other factors, such as a reduction of the global population? Scientists generally believe that the current human population of more than 8 billion people is well beyond the limits of our finite planet, especially if a large fraction of this population aspires to the resource-intensive lifestyles of wealthy nations. Some estimates suggest that a more sustainable population might be more like 2 billion , which could reduce energy use significantly, potentially by a factor of three or four. However, this isn’t a real solution: again, as with the example of improved energy efficiency, a one-time reduction of our energy consumption by a factor of three will quickly be swallowed up by an inexorable rise in energy use. If Earth’s population were suddenly reduced to 2 billion – about a quarter of the current population – our energy gains would initially be enormous. But those gains would be erased in two doubling times, or roughly 60-100 years , as our energy demands would grow fourfold.

S o, why aren’t more people talking about this? The deep warming problem is starting to get more attention. It was recently mentioned on Twitter by the German climate scientist Stefan Rahmstorf, who cautioned that nuclear fusion, despite excitement over recent advances, won’t arrive in time to save us from our waste heat, and might make the problem worse. By providing another cheap source of energy, fusion energy could accelerate both the growth of our energy use and the reckoning of deep warming. A student of Rahmstorf’s, Peter Steiglechner, wrote his master’s thesis on the problem in 2018. Recognition of deep warming and its long-term implications for humanity is spreading. But what can we do about the problem?

Avoiding or delaying deep warming will involve slowing the rise of our waste heat, which means restricting the amount of energy we use and also choosing energy sources that exacerbate the problem as little as possible. Unlike the energy from fossil fuels or nuclear power, which add to our waste energy burden, renewable energy sources intercept energy that is already on its way to Earth, rather than producing additional waste heat. In this sense, the deep warming problem is another reason to pursue renewable energy sources such as solar or wind rather than alternatives such as nuclear fusion, fission or even geothermal power. If we derive energy from any of these sources, we’re unleashing new flows of energy into the Earth system without making a compensating reduction. As a result, all such sources will add to the waste heat problem. However, if renewable sources of energy are deployed correctly, they need not add to our deposition of waste heat in the environment. By using this energy, we produce no more waste heat than would have been created by sunlight in the first place.

Take the example of wind energy. Sunlight first stirs winds into motion by heating parts of the planet unequally, causing vast cells of convection. As wind churns through the atmosphere, blows through trees and over mountains and waves, most of its energy gets turned into heat, ending up in the microscopic motions of molecules. If we harvest some of this wind energy through turbines, it will also be turned into heat in the form of stored energy. But, crucially, no more heat is generated than if there had been no turbines to capture the wind.

The same can hold true for solar energy. In an array of solar cells, if each cell only collects the sunlight falling on it – which would ordinarily have been absorbed by Earth’s surface – then the cells don’t alter how much waste heat gets produced as they generate energy. The light that would have warmed Earth’s surface instead goes into the solar cells, gets used by people for some purpose, and then later ends up as heat. In this way we reduce the amount of heat being absorbed by Earth by precisely the same amount as the energy we are extracting for human use. We are not adding to overall planetary heating. This keeps the waste energy burden unchanged, at least in the relatively near future, even if we go on extracting and using ever larger amounts of energy.

Covering deserts in dark panels would absorb a lot more energy than the desert floor

Chaisson summarised the problem quite clearly in 2008:

I’m now of the opinion … that any energy that’s dug up on Earth – including all fossil fuels of course, but also nuclear and ground-sourced geothermal – will inevitably produce waste heat as a byproduct of humankind’s use of energy. The only exception to that is energy arriving from beyond Earth, this is energy here and now and not dug up, namely the many solar energies (plural) caused by the Sun’s rays landing here daily … The need to avoid waste heat is indeed the single, strongest, scientific argument to embrace solar energies of all types.

But not just any method of gathering solar energy will avoid the deep warming problem. Doing so requires careful engineering. For example, covering deserts with solar panels would add to planetary heating because deserts reflect a lot of incident light back out to space, so it is never absorbed by Earth (and therefore doesn’t produce waste heat). Covering deserts in dark panels would absorb a lot more energy than the desert floor and would heat the planet further.

We’ll also face serious problems in the long run if our energy appetite keeps increasing. Futurists dream of technologies deployed in space where huge panels would absorb sunlight that would otherwise have passed by Earth and never entered our atmosphere. Ultimately, they believe, this energy could be beamed down to Earth. Like nuclear energy, such technologies would add an additional energy source to the planet without any compensating removal of heating from the sunlight currently striking our planet’s surface. Any effort to produce more energy than is normally available from sunlight at Earth’s surface will only make our heating problems worse.

D eep warming is simply a consequence of the laws of physics and our inquisitive nature. It seems to be in our nature to constantly learn and develop new things, changing our environment in the process. For thousands of years, we have harvested and exploited ever greater quantities of energy in this pursuit, and we appear poised to continue along this path with the rapidly expanding use of renewable energy sources – and perhaps even more novel sources such as nuclear fusion. But this path cannot proceed indefinitely without consequences.

The logic that more energy equals more warming sets up a profound dilemma for our future. The laws of physics and the habits ingrained in us from our long evolutionary history are steering us toward trouble. We may have a technological fix for greenhouse gas warming – just shift from fossil fuels to cleaner energy sources – but there is no technical trick to get us out of the deep warming problem. That won’t stop some scientists from trying.

Perhaps, believing that humanity is incapable of reducing its energy usage, we’ll adopt a fantastic scheme to cool the planet, such as planetary-scale refrigeration or using artificially engineered tornadoes to transport heat from Earth’s surface to the upper atmosphere where it can be radiated away to space. As far-fetched as such approaches sound, scientists have given some serious thought to these and other equally bizarre ideas, which seem wholly in the realm of science fiction. They’re schemes that will likely make the problem worse not better.

We will need to transform the human story. It must become a story of doing less, not more

I see several possibilities for how we might ultimately respond. As with greenhouse gas warming, there will probably be an initial period of disbelief, denial and inaction, as we continue with unconstrained technological advance and growing energy use. Our planet will continue warming. Sooner or later, however, such warming will lead to serious disruptions of the Earth environment and its ecosystems. We won’t be able to ignore this for long, and it may provide a natural counterbalance to our energy use, as our technical and social capacity to generate and use ever more energy will be eroded. We may eventually come to some uncomfortable balance in which we just scrabble out a life on a hot, compromised planet because we lack the moral and organisational ability to restrict our energy use enough to maintain a sound environment.

An alternative would require a radical break with our past: using less energy. Finding a way to use less energy would represent a truly fundamental rupture with all of human history, something entirely novel. A rupture of this magnitude won’t come easily. However, if we could learn to view restrictions on our energy use as a non-negotiable element of life on Earth, we may still be able to do many of the things that make us essentially human: learning, discovering, inventing, creating. In this scenario, any helpful new technology that comes into use and begins using lots of energy would require a balancing reduction in energy use elsewhere. In such a way, we might go on with the future being perpetually new, and possibly better.

None of this is easily achieved and will likely mirror our current struggles to come to agreements on greenhouse gas heating. There will be vicious squabbles, arguments and profound polarisation, quite possibly major wars. Humanity will never have faced a challenge of this magnitude, and we won’t face up to it quickly or easily, I expect. But we must. Planetary heating is in our future – the very near future and further out as well. Many people will find this conclusion surprisingly hard to swallow, perhaps because it implies fundamental restrictions on our future here on Earth: we can’t go on forever using more and more energy, and, at the same time, expecting the planet’s climate to remain stable.

The world will likely be transformed by 2050. And, sometime after that, we will need to transform the human story. The narrative arc of humanity must become a tale of continuing innovation and learning, but also one of careful management. It must become a story, in energy terms, of doing less, not more. There’s no technology for entirely escaping waste heat, only techniques.

This is important to remember as we face up to the extremely urgent challenge of heating linked to fossil-fuel use and greenhouse gases. Global warming is just the beginning of our problems. It’s a testing ground to see if we can manage an intelligent and coordinated response. If we can handle this challenge, we might be better prepared, more capable and resilient as a species to tackle an even harder one.

ग्लोबल वार्मिंग पर निबंध – कारण और समाधान

ग्लोबल वार्मिंग पर 500+ शब्द निबंध.

ग्लोबल वार्मिंग एक ऐसा शब्द है जिससे लगभग हर कोई परिचित है। लेकिन, इसका अर्थ अभी भी हम में से अधिकांश के लिए स्पष्ट नहीं है। तो, ग्लोबल वार्मिंग पृथ्वी के वातावरण के समग्र तापमान में क्रमिक वृद्धि को संदर्भित करता है। विभिन्न गतिविधियां हो रही हैं जो धीरे-धीरे तापमान बढ़ा रही हैं। ग्लोबल वार्मिंग हमारे हिम ग्लेशियरों को तेजी से पिघला रहा है। यह धरती के साथ-साथ इंसानों के लिए भी बेहद हानिकारक है। ग्लोबल वार्मिंग को नियंत्रित करना काफी चुनौतीपूर्ण है; हालाँकि, यह असहनीय नहीं है। किसी भी समस्या को हल करने में पहला कदम समस्या के कारण की पहचान करना है। इसलिए, हमें पहले ग्लोबल वार्मिंग के कारणों को समझने की आवश्यकता है जो हमें इसे हल करने में आगे बढ़ने में मदद करेंगे। ग्लोबल वार्मिंग पर इस निबंध में, हम ग्लोबल वार्मिंग के कारणों और समाधानों को देखेंगे।

ग्लोबल वार्मिंग के कारण

ग्लोबल वार्मिंग एक गंभीर समस्या बन गई है जिस पर अविभाजित ध्यान देने की आवश्यकता है। यह किसी एक कारण से नहीं बल्कि कई कारणों से हो रहा है। ये कारण प्राकृतिक और मानव निर्मित दोनों हैं। प्राकृतिक कारणों में ग्रीनहाउस गैसों की रिहाई शामिल है जो पृथ्वी से भागने में सक्षम नहीं हैं, जिससे तापमान में वृद्धि होती है।

इसके अलावा, ज्वालामुखी विस्फोट भी ग्लोबल वार्मिंग के लिए जिम्मेदार हैं। यह कहना है कि, इन विस्फोटों से कार्बन डाइऑक्साइड के टन निकलते हैं जो ग्लोबल वार्मिंग में योगदान करते हैं। इसी तरह, मीथेन भी ग्लोबल वार्मिंग के लिए जिम्मेदार एक बड़ा मुद्दा है।

उसके बाद, ऑटोमोबाइल और जीवाश्म ईंधन के अत्यधिक उपयोग से कार्बन डाइऑक्साइड का स्तर बढ़ जाता है। इसके अतिरिक्त, खनन और पशु पालन जैसी गतिविधियाँ पर्यावरण के लिए बहुत हानिकारक हैं। सबसे आम मुद्दों में से एक है जो तेजी से हो रहा है वनों की कटाई।

इसलिए, जब कार्बन डाइऑक्साइड के अवशोषण के सबसे बड़े स्रोतों में से एक ही गायब हो जाएगा, तो गैस को विनियमित करने के लिए कुछ भी नहीं रहेगा। इस प्रकार, यह ग्लोबल वार्मिंग में परिणाम देगा। ग्लोबल वार्मिंग को रोकने और धरती को फिर से बेहतर बनाने के लिए तुरंत कदम उठाए जाने चाहिए।

ग्लोबल वार्मिंग समाधान

जैसा कि पहले कहा गया है, यह चुनौतीपूर्ण हो सकता है लेकिन यह पूरी तरह से असंभव नहीं है। जब संयुक्त प्रयास किए जाते हैं तो ग्लोबल वार्मिंग को रोका जा सकता है। इसके लिए, व्यक्तियों और सरकारों, दोनों को इसे प्राप्त करने की दिशा में कदम उठाने होंगे। हमें ग्रीनहाउस गैस की कमी से शुरू करना चाहिए।

इसके अलावा, उन्हें गैसोलीन की खपत पर नजर रखने की जरूरत है। एक हाइब्रिड कार पर स्विच करें और कार्बन डाइऑक्साइड की रिहाई को कम करें। इसके अलावा, नागरिक सार्वजनिक परिवहन या कारपूल को एक साथ चुन सकते हैं। इसके बाद, रीसाइक्लिंग को भी प्रोत्साहित किया जाना चाहिए।

ग्रीनहाउस प्रभाव क्या है?

उदाहरण के लिए, जब आप खरीदारी करने जाते हैं, तो अपने कपड़े की थैली ले जाएं। एक और कदम जो आप उठा सकते हैं वह है बिजली के उपयोग को सीमित करना जो कार्बन डाइऑक्साइड की रिहाई को रोक देगा। सरकार के हिस्से पर, उन्हें औद्योगिक कचरे को नियंत्रित करना चाहिए और उन्हें हवा में हानिकारक गैसों को बाहर निकालने से रोकना चाहिए। वनों की कटाई को तुरंत रोका जाना चाहिए और पेड़ों के रोपण को प्रोत्साहित किया जाना चाहिए।

संक्षेप में, हम सभी को इस तथ्य का एहसास होना चाहिए कि हमारी पृथ्वी ठीक नहीं है। इसका इलाज करने की जरूरत है और हम इसे ठीक करने में मदद कर सकते हैं। वर्तमान पीढ़ी को भविष्य की पीढ़ियों की पीड़ा को रोकने के लिए ग्लोबल वार्मिंग को रोकने की जिम्मेदारी लेनी चाहिए। इसलिए, हर छोटा कदम, कोई फर्क नहीं पड़ता कि कैसे छोटा वजन बहुत वहन करता है और ग्लोबल वार्मिंग को रोकने में काफी महत्वपूर्ण है।

ग्लोबल वार्मिंग पर अक्सर पूछे जाने वाले प्रश्न Q.1 ग्लोबल वार्मिंग के कारणों की सूची बनाएँ।

A.1 प्राकृतिक और मानव निर्मित दोनों प्रकार के ग्लोबल वार्मिंग के विभिन्न कारण हैं। प्राकृतिक एक में ग्रीनहाउस गैस, ज्वालामुखी विस्फोट, मीथेन गैस और बहुत कुछ शामिल हैं। अगला, मानव निर्मित कारण वनों की कटाई, खनन, मवेशी पालन, जीवाश्म ईंधन जलाना और अधिक हैं।

Q.2 ग्लोबल वार्मिंग को कोई कैसे रोक सकता है?

A.2 ग्लोबल वार्मिंग को व्यक्तियों और सरकार के संयुक्त प्रयास से रोका जा सकता है। वनों की कटाई पर रोक लगाई जानी चाहिए और पेड़ों को अधिक लगाया जाना चाहिए। ऑटोमोबाइल का उपयोग सीमित होना चाहिए और रीसाइक्लिंग को प्रोत्साहित किया जाना चाहिए।

Global Warming Definition, Causes, Effects, Impacts, Solutions

Global Warming is a long-term increase in average global temperature. Read about Global Warming Definition, Causes, Effects, Impact on Climate Change & Solutions for the UPSC exam.

Table of Contents

What is Global Warming?

Global Warming is a long-term increase in average global temperature. It is considered a natural phenomenon, but anthropogenic activities on earth, particularly post Industrial Revolution , have led to an increase in the rate of this temperature increase. Various Reports published by the International Panel on Climate Change (IPCC) have time and again highlighted that since 1850 human activities have led to an increase of about 1 degree Celsius in average global temperature. Most of this warming has taken place in the second half of the 20th century. The fact that 5 of the hottest recorded year have occurred since 2015 can help us better understand the calamitous impact of anthropogenic activities.

Global Warming Causes

Green House Gases also known as GHGs in the atmosphere trap the solar radiations that are reflected by the earth’s surface. Under normal circumstances, most of these radiations escape into outer space. However, the release of GHGs by anthropogenic activities has increased their concentration in the atmosphere. Thus, the earth is getting hotter and hotter. 

Some of the common GHGs include carbon dioxide, methane, nitrous oxide, chlorofluorocarbons, and water vapour, among others. The global warming potential of each GHG is different. For example, methane has a 25-time warming potential than carbon dioxide. Similarly, nitrous oxide has more than 250 times the warming potential than carbon dioxide. The top  anthropogenic activities that are responsible for the release of GHGs are shown below.

Global Warming and Green House Effect

Both phenomena are related to each other. Green House Gases also known as GHGs in the atmosphere trap the solar radiations that are reflected by the earth’s surface. Under normal circumstances, most of these radiations escape into outer space. However, the release of GHGs by anthropogenic activities has increased their concentration in the atmosphere. This is the primary cause of Global Warming . 

Global Warming Effects

Increase in the average temperature of the earth.

According to IPCC reports, human-induced global warming is responsible for nearly 1 degree Celsius temperature rise vis a vis pre-industrial level. Data from NASA suggest that 2016 has been the hottest year on record.

Frequency of Extreme Weather Events is Increasing

Across the globe, extreme weather events have increased in occurrence. For example, forest fires in California have become an annual event. Also, it is increasing in frequency each year. Most recently, we have recorded the phenomena of heat waves in Antarctica. The intensity of cyclones in the Bay of Bengal region has increased. Similarly, the frequency of occurrence of El Niño and La Niña has reduced from once in 8–10 years to once in 3–4 years now. More frequent episodes of floods and drought are being recorded every year across the world.

Melting of Ice

According to IPCC, there is 10% less permafrost in North Hemisphere at present compared to the 1900s. Remote sensing data suggest Arctic ice is melting fast. Experts suggest that not only will the sea level rise with the melting of glaciers, but there is also a danger of new bacteria and viruses being released into the environment which has so far been trapped in ice sheets. This may lead to outbreaks of disease and pandemics which are beyond the control of human medical sciences.

Sea Level Rise and Acidification of Ocean

A report published by WMO, suggests that the rate of sea level rise has doubled for the period between 2013 and 2021 compared to the rate for the period between 1993 and 2002. Earth scientists are suggesting that if this phenomenon continues, many human-inhabited coastal areas will be submerged into the sea in the coming decades. Also, with the concentration of carbon dioxide rising in the atmosphere, oceans are absorbing more of it. This is leading to ocean acidification. The impact of this phenomenon can be disastrous for ocean biodiversity, particularly the coral reefs. 

Adverse Impact on Terrestrial Ecosystems of the Earth

It has been recorded that many flora and fauna species are heading northwards in Northern Hemisphere. Significant changes have been observed in the migratory movements of birds across the world. Early arrival to their summer feeding and breeding grounds is quite evident. Expert biologists suggest that rising temperatures in the tropical and subtropical regions may lead to an outbreak of new diseases, which in turn may render many floral and faunal species extinct.

Social and Economic Impact

A rising number of extreme weather events will have an adverse impact on agriculture and fisheries. Rising global temperatures will have a negative impact on the productivity of human beings, particularly in tropical and subtropical regions of the earth. The impact on life and livelihoods of indigenous people across the world will be even more pronounced. 

Global Warming Solutions

Global cooperation for reduction of emissions.

It is time that the target of containing the global average temperature rise within 1.5 degrees Celsius of pre-industrial levels is taken seriously. Also, global efforts should be based on a spirit of Common But Differentiated Responsibility. This will ensure that historical injustices done to the global south are duly acknowledged, and they have an equal chance to transform themselves into developed countries. Countries must act proactively to achieve Net Zero Emission status at the earliest. 

Transition to Cleaner and Greener Forms of Energy

Thermal power plants based on coal should be made more efficient and inefficient ones should be phased off. Also, mass adoption of renewable forms of energy like solar should be promoted. Similarly, avenues for using hydrogen as energy fuel should be looked into. We must also explore the possibility of Nuclear fusion for energy generation, in addition to making nuclear fission-based energy generation safer.

Changes in Agricultural Practices and Land Use

Agriculture based on the use of nitrogenous fertilizers must be replaced with organic farming techniques. Also, methane gas released from agricultural and cattle waste must be trapped as biogas for domestic usage. Massive afforestation drives must be organized. Urban governments must make it a point to include green spaces in urban planning.

Improving Transportation System

The advent of E-vehicles is a welcome change, but we need to make the batteries used in these vehicles more efficient. Urban planners must make public transportation systems inherent as a benchmark of good urban planning. Also, urban planning should be such that it promotes more walking and cycling habits among the residents. 

Behavioural Changes

All the above discussions will have no meaning if we as individuals are not sensitive enough. We need to make reducing, reusing and recycling a mantra of our living. It should be our civic duty to save water, and wildlife and raise awareness among others. 

Solar Geoengineering

Solar geoengineering, a proposed climate intervention method, aims to counteract global warming by reflecting a portion of the sun’s rays back into space. One prominent approach involves injecting substances like sulphur dioxide into the upper atmosphere to create reflective aerosols. These particles can scatter sunlight, reducing the Earth’s temperature. However, solar geoengineering is a topic of debate, with concerns about its side effects, such as disrupted weather patterns and potential geopolitical risks. Research in this field is ongoing, but it remains a theoretical concept with limited practical implementation.

Can Solar Geoengineering Halt Global Warming?

Solar geoengineering, specifically solar radiation management (SRM), is under scrutiny as a potential method to mitigate global warming. SRM involves reflecting sunlight away from Earth, often by injecting substances like sulphur dioxide into the upper atmosphere to create reflective aerosols. However, its effectiveness remains a subject of debate, with concerns about potential side effects and ethical implications. While research in this field is ongoing, solar geoengineering is currently in a theoretical stage, with limited practical implementation.

Global Warming Conclusion

It is rightly said that “Charity begins at home.” Climate action will be more efficient if we go by this spirit. To begin with, each individual can make sure that what is happening in their house and immediate surroundings is in harmony with the environment. If this can happen, all the policies we are making at the local, national, regional and global levels will give far better results. 

Global Warming UPSC

Each year, we read about rising global temperatures. Also, catching the headlines is the news related to disasters caused by events like cyclones, forest fires, floods and drought. All these phenomena can be attributed to one single cause which is global warming. 

Global Warming is a long-term increase in average global temperature. It is considered a natural phenomenon, but anthropogenic activities on earth, particularly post-Industrial Revolution, have led to an increase in the rate of this temperature increase.

Global warming is the long-term warming of the planet’s overall temperature. Though this warming trend has been going on for a long time, its pace has significantly increased in the last hundred years due to the burning of fossil fuels . As the human population has increased, so has the volume of fossil fuels burned. Fossil fuels include coal, oil, and natural gas, and burning them causes what is known as the “greenhouse effect” in Earth’s atmosphere.

The greenhouse effect is when the sun’s rays penetrate the atmosphere, but when that heat is reflected off the surface cannot escape back into space. Gases produced by the burning of fossil fuels prevent the heat from leaving the atmosphere. These greenhouse gasses are carbon dioxide , chlorofluorocarbons, water vapor , methane , and nitrous oxide . The excess heat in the atmosphere has caused the average global temperature to rise overtime, otherwise known as global warming.

Global warming has presented another issue called climate change. Sometimes these phrases are used interchangeably, however, they are different. Climate change refers to changes in weather patterns and growing seasons around the world. It also refers to sea level rise caused by the expansion of warmer seas and melting ice sheets and glaciers . Global warming causes climate change, which poses a serious threat to life on Earth in the forms of widespread flooding and extreme weather. Scientists continue to study global warming and its impact on Earth.

Global Warming Awareness Essay

Introduction

While talking about environmental pollution , children might have heard how it leads to various problems like global warming and climate change. Whenever the topic is discussed, global warming takes centre stage. Despite the repetitive utterance of the word, children fail to understand its real meaning or importance. So, this global warming awareness essay is aimed at the young learners to better acquaint them with the problems faced due to global warming.

Global warming is a phenomenon where the temperature gradually increases in the atmosphere of Earth due to both natural and human-made causes. As global warming results in climate change and the melting of glaciers, which will have serious repercussions on Earth and the living beings on the planet, efforts should be made to control it. The short essay on global warming awareness will throw light on this aspect, thus highlighting the significance of creating awareness of the phenomenon.

Importance of Global Warming Awareness

Global warming will affect us today or tomorrow. Though its effect can only be seen in a few places now, it won’t be long before it hits other places too. So, it is not wise for us to sit calmly and think that we are not being affected. In the global warming awareness essay, we will be discussing the causes of global warming , thereby emphasising the need to address the concern.

It is said that the increase in greenhouse gases results in global warming, which, in turn, leads to severe consequences like the melting of ice as well as causing frequent droughts and floods. But people are not aware of these problems, and they believe that all these things are merely said for the sake of it. This is why we must educate them about global warming and its issues through the short essay on global warming awareness essay so that we can take one step at a time in protecting ourselves and our planet.

Ways to Raise Global Warming Awareness

Global warming is not a simple topic to make our children familiar with, but this global warming awareness essay will help you in making your task easier. Let us make them realise by connecting their feelings to that of a polar bear. We can simply ask our children how they would feel when their home is taken away and they are left to live without it. Then, we can link it to the situation of the polar bear, where its home (glaciers) is destroyed due to global warming.

Similarly, we can encourage them to show respect towards our planet through small yet impactful actions, like switching off lights when not in use, cleaning the surroundings etc. By teaching these actions, we are saving ourselves when we care for our Earth, and we can help them grow as conscientious individuals.

Let this short essay on global warming awareness essay be a guide for our children to realise the problems faced by us. You can also check out other essays on BYJU’S website that will make our children knowledgeable.

Frequently Asked Questions on Global Warming Awareness Essay

Why is it necessary to have awareness about global warming.

If people are not aware of global warming, we will not be able to stop our planet from destruction, and our lives will be impacted severely. Hence, it is necessary to create awareness about global warming.

How will the global warming awareness essay be useful for children?

The essay will be useful for children to understand more about global warming, its causes and effects. As they will be informed about it, they will be careful in their actions to not harm our planet.

Essay on Climate Change

Climate Change Essay - The globe is growing increasingly sensitive to climate change. It is currently a serious worldwide concern. The term "Climate Change" describes changes to the earth's climate. It explains the atmospheric changes that have occurred across time, spanning from decades to millions of years. Here are some sample essays on climate change.

100 Words Essay on Climate Change

200 words essay on climate change, 500 words essay on climate change.

The climatic conditions on Earth are changing due to climate change. Several internal and external variables, such as solar radiation, variations in the Earth's orbit, volcanic eruptions, plate tectonics, etc., are to blame for this.

There are strategies for climate change reduction. If not implemented, the weather might get worse, there might be water scarcity, there could be lower agricultural output, and it might affect people's ability to make a living. In order to breathe clean air and drink pure water, you must concentrate on limiting human activity. These are the simple measures that may be taken to safeguard the environment and its resources.

The climate of the Earth has changed significantly over time. While some of these changes were brought on by natural events like volcanic eruptions, floods, forest fires, etc., many of the changes were brought on by human activity. The burning of fossil fuels, domesticating livestock, and other human activities produce a significant quantity of greenhouse gases. This results in an increase of greenhouse effect and global warming which are the major causes for climate change.

Reasons of Climate Change

Some of the reasons of climate change are:

Deforestation

Excessive use of fossil fuels

Water and soil pollution

Plastic and other non biodegradable waste

Wildlife and nature extinction

Consequences of Climate Change

All kinds of life on earth will be affected by climate change if it continues to change at the same pace. The earth's temperature will increase, the monsoon patterns will shift, the sea level will rise, and there will be more frequent storms, volcano eruptions, and other natural calamities. The earth's biological and ecological equilibrium will be disturbed. Humans won't be able to access clean water or air to breathe when the environment becomes contaminated. The end of life on this earth is imminent. To reduce the issue of climate change, we need to bring social awareness along with strict measures to protect and preserve the natural environment.

A shift in the world's climatic pattern is referred to as climate change. Over the centuries, the climate pattern of our planet has undergone modifications. The amount of carbon dioxide in the atmosphere has significantly grown.

When Did Climate Change Begin

It is possible to see signs of climate change as early as the beginning of the industrial revolution. The pace at which the manufacturers produced things on a large scale required a significant amount of raw materials. Since the raw materials being transformed into finished products now have such huge potential for profit, these business models have spread quickly over the world. Hazardous substances and chemicals build up in the environment as a result of company emissions and waste disposal.

Although climate change is a natural occurrence, it is evident that human activity is turning into the primary cause of the current climate change situation. The major cause is the growing population. Natural resources are utilised more and more as a result of the population's fast growth placing a heavy burden on the available resources. Over time, as more and more products and services are created, pollution will eventually increase.

Causes of Climate Change

There are a number of factors that have contributed towards weather change in the past and continue to do so. Let us look at a few:

Solar Radiation |The climate of earth is determined by how quickly the sun's energy is absorbed and distributed throughout space. This energy is transmitted throughout the world by the winds, ocean currents etc which affects the climatic conditions of the world. Changes in solar intensity have an effect on the world's climate.

Deforestation | The atmosphere's carbon dioxide is stored by trees. As a result of their destruction, carbon dioxide builds up more quickly since there are no trees to absorb it. Additionally, trees release the carbon they stored when we burn them.

Agriculture | Many kinds of greenhouse gases are released into the atmosphere by growing crops and raising livestock. Animals, for instance, create methane, a greenhouse gas that is 30 times more potent than carbon dioxide. The nitrous oxide used in fertilisers is roughly 300 times more strong than carbon dioxide.

How to Prevent Climate Change

We need to look out for drastic steps to stop climate change since it is affecting the resources and life on our planet. We can stop climate change if the right solutions are put in place. Here are some strategies for reducing climate change:

Raising public awareness of climate change

Prohibiting tree-cutting and deforestation.

Ensure the surroundings are clean.

Refrain from using chemical fertilisers.

Water and other natural resource waste should be reduced.

Protect the animals and plants.

Purchase energy-efficient goods and equipment.

Increase the number of trees in the neighbourhood and its surroundings.

Follow the law and safeguard the environment's resources.

Reduce the amount of energy you use.

During the last few decades especially, climate change has grown to be of concern. Global concern has been raised over changes in the Earth's climatic pattern. The causes of climate change are numerous, as well as the effects of it and it is our responsibility as inhabitants of this planet to look after its well being and leave it in a better condition for future generations.

Global Warming Par Nibandh: जानिए ग्लोबल वार्मिंग पर निबंध 

• Updated on  
• फरवरी 16, 2024

ग्लोबल वार्मिंग को समझने से छात्रों में पर्यावरण के प्रति गहरी संवेदना विकसित करने में मदद मिलती है।  वे जलवायु परिवर्तन के कारणों और परिणामों के साथ-साथ प्राकृतिक पारिस्थितिकी तंत्र और जैव विविधता के बारे में सीखते हैं। आने वाले दशकों में ग्लोबल वार्मिंग का दुनिया पर महत्वपूर्ण प्रभाव पड़ेगा, जिससे मौसम के पैटर्न से लेकर समुद्र के स्तर से लेकर पारिस्थितिक तंत्र तक सब कुछ प्रभावित होगा। ग्लोबल वार्मिंग के बारे में अभी सीखकर, छात्र भविष्य में इन परिवर्तनों के लिए बेहतर तैयारी कर सकते हैं और उन्हें अपना सकते हैं। इसलिए कई बार छात्रों को ग्लोबल वार्मिंग पर निबंध तैयार करने को दिया जाता है। Global Warming Par Nibandh के बारे में जानने के लिए इस ब्लॉग को अंत तक पढ़ें। 

This Blog Includes:

ग्लोबल वार्मिंग के बारे में : global warming par nibandh, ग्लोबल वार्मिंग पर 100 शब्दों में निबंध, ग्लोबल वार्मिंग पर 200 शब्दों में निबंध, ग्लोबल वार्मिंग के कारण, ग्लोबल वार्मिंग के परिणाम, ग्लोबल वार्मिंग पर 10 लाइन्स .

ग्लोबल वार्मिंग को आसान शब्दों में समझें तो मुख्यत: यह मानवीय गतिविधियों के कारण होती है। मुख्य रूप से वायुमंडल में ग्रीनहाउस गेसें बढ़ रही है। इस कारण से पृथ्वी की औसत सतह के तापमान में धीरे धीरे समय के साथ वृद्धि हो रही है। ये गैसें, जैसे कार्बन डाइऑक्साइड (CO2), मीथेन (CH4), और नाइट्रस ऑक्साइड (N2O), सूर्य की गर्मी को पृथ्वी के वायुमंडल में घेर के रखती हैं, जिससे वार्मिंग प्रभाव पैदा होता है जिसे ग्रीनहाउस प्रभाव के रूप में जाना जाता है। ऊर्जा के लिए जीवाश्म ईंधन जलाने, वनों की कटाई, औद्योगिक प्रक्रियाओं और कृषि पद्धतियों जैसी मानवीय गतिविधियों ने औद्योगिक क्रांति के बाद से वातावरण में ग्रीनहाउस गैसों की सांद्रता में उल्लेखनीय वृद्धि की है।  इस बढ़े हुए ग्रीनहाउस प्रभाव के कारण विश्व स्तर पर तापमान में वृद्धि हो रही है, जिसके परिणामस्वरूप जलवायु पैटर्न में बदलाव, समुद्र के स्तर में वृद्धि, ग्लेशियरों और बर्फ की चोटियों का पिघलना, मौसम की घटनाएं और पारिस्थितिक तंत्र और वन्यजीव आवासों में व्यवधान हो रहा है।

ग्लोबल वार्मिंग जलवायु परिवर्तन का एक प्रमुख घटक है, जिसमें समय के साथ तापमान, वर्षा और मौसम के पैटर्न में व्यापक बदलाव शामिल हैं। जबकि कुछ प्राकृतिक कारक जैसे ज्वालामुखी विस्फोट और सौर विकिरण, पृथ्वी की जलवायु को प्रभावित कर सकते हैं, तेजी से तापमान बढ़ने की वर्तमान प्रवृत्ति मुख्य रूप से मानवीय गतिविधियों से प्रेरित है। ग्लोबल वार्मिंग को कम करने के लिए ग्रीनहाउस गैस उत्सर्जन को कम करने, नवीकरणीय ऊर्जा स्रोतों को बढ़ाना, जंगलों और आर्द्रभूमि जैसे प्राकृतिक कार्बन सिंक की रक्षा और पुनर्स्थापित करने और जलवायु परिवर्तन के प्रभावों को अनुकूलित करने के लिए ठोस प्रयासों की आवश्यकता है।

Global Warming Par Nibandh 100 शब्दों में निबंध नीचे दिया गया है:

ग्लोबल वार्मिंग एक गंभीर पर्यावरणीय समस्या है जो मानव गतिविधियों के कारण वायुमंडल में कार्बन डाइऑक्साइड जैसी ग्रीनहाउस गैसों को छोड़ती है। ये गैसें सूर्य की गर्मी को सोख लेती हैं, जिससे पृथ्वी के तापमान में धीरे-धीरे वृद्धि होती है। यह वार्मिंग मौसम के पैटर्न को प्रभावित करती है, बर्फ की चोटियों के पिघलने का कारण बनती है और समुद्र के स्तर को बढ़ाती है। यह पारिस्थितिकी तंत्र को भी नुकसान पहुंचाता है। वन्यजीवों को खतरे में डालता है और आवासों को बाधित करता है। ग्लोबल वार्मिंग से निपटने के लिए, हमें नवीकरणीय ऊर्जा का उपयोग, ऊर्जा संरक्षण और पेड़ लगाकर अपने आस पास कार्बन को कम करना होगा।  इसके अतिरिक्त, इस जरूरी समस्या के समाधान और भावी पीढ़ियों के लिए हमारे ग्रह की सुरक्षा के लिए अंतर्राष्ट्रीय सहयोग और नीतियां आवश्यक हैं।

Global Warming Par Nibandh 200 शब्दों में निबंध नीचे दिया गया है:

ग्लोबल वार्मिंग का मतलब समय के साथ पृथ्वी के औसत तापमान में क्रमिक वृद्धि है। मानवीय गतिविधियाँ, विशेषकर बड़े पैमाने पर वनों की कटाई ग्लोबल वार्मिंग के प्रमुख योगदानकर्ता हैं। बढ़ती मानव आबादी के साथ, ईंधन की मांग आसमान छू रही है, जिससे सीमित प्राकृतिक संसाधनों पर दबाव बढ़ गया है। वनों और जलमार्गों जैसे संसाधनों का अत्यधिक उपयोग पारिस्थितिक तंत्र के संतुलन को बिगाड़ सकता है।

ग्लोबल वार्मिंग का मतलब सिर्फ उच्च तापमान नहीं है;  यह दुनिया भर में तूफान, बाढ़ और हिमस्खलन जैसी प्राकृतिक आपदाओं का भी कारण बनता है। ये आपदाएँ सीधे तौर पर ग्लोबल वार्मिंग से जुड़ी हैं। पर्यावरण की रक्षा के लिए, हमें ग्लोबल वार्मिंग के प्रभावों का सामना करने के लिए अपने पारिस्थितिक तंत्र को मजबूत करने की आवश्यकता है।

भावी पीढ़ियों के लिए अपने ग्रह को स्वस्थ बनाने के लिए मिलकर काम करना हमारे लिए महत्वपूर्ण है। पेड़ लगाना हमारी दुनिया को बेहतर बनाने का एक सरल लेकिन प्रभावी तरीका है। पुनर्वनीकरण को सर्वोच्च प्राथमिकता होनी चाहिए। यदि हममें से प्रत्येक व्यक्ति अपने जीवनकाल में यथासंभव अधिक से अधिक पेड़ लगाने का संकल्प ले, तो हम एक महत्वपूर्ण अंतर ला सकते हैं। आइए सभी के लिए संजोने योग्य एक बेहतर पृथ्वी बनाने के लिए एक साथ मिलकर काम करें। 

ग्लोबल वार्मिंग पर 500 शब्दों में निबंध

Global Warming Par Nibandh 500 शब्दों में निबंध नीचे दिया गया है:

ग्लोबल वार्मिंग एक गंभीर पर्यावरणीय मुद्दा है जिस पर हमें तत्काल ध्यान देने की आवश्यकता है। यह मानवीय गतिविधियों के कारण समय के साथ पृथ्वी के औसत तापमान में लगातार वृद्धि की समस्या को दर्शाता है।  इस घटना के हमारे ग्रह के पारिस्थितिकी तंत्र, मौसम के पैटर्न और समग्र जलवायु स्थिरता पर दूरगामी परिणाम हो रहे हैं।  जीवाश्म ईंधन के जलने से लेकर वनों की कटाई और औद्योगिक गतिविधियों तक, मानवीय कार्यों ने वायुमंडल में ग्रीनहाउस गैसों के संचय में महत्वपूर्ण योगदान दिया है, जिससे ग्रीनहाउस प्रभाव बढ़ गया है और तापमान में वृद्धि हुई है। वैश्विक तापमान में वृद्धि जारी है, ग्लोबल वार्मिंग के प्रभाव तेजी से बढ़ रहे हैं। जिससे लगातार और तीव्र गर्मी की लहरें, ध्रुवीय बर्फ के पिघलने, समुद्र के स्तर में वृद्धि और पारिस्थितिक तंत्र और वन्यजीव आवासों में समस्या के रूप में प्रकट हो रहे हैं। ग्लोबल वार्मिंग को कम करने के लिए वैश्विक स्तर पर सभी लोगों का कार्य करना आवश्यक है। जिसमें ग्रीनहाउस गैस उत्सर्जन को कम करना, नवीकरणीय ऊर्जा स्रोतों में बदलाव और स्थायी भूमि उपयोग जैसे कार्य करना भी शामिल है। ठोस प्रयासों से हम ग्लोबल वार्मिंग के प्रभाव को कम कर सकते हैं और आने वाली पीढ़ियों के लिए अपने ग्रह के भविष्य को सुरक्षित रख सकते हैं।

ग्लोबल वार्मिंग कई कारणों से होती है। ग्लोबल वार्मिंग मौसम और प्राकृतिक आपदाओं जैसी गंभीर समस्याओं का कारण बन रही है। ऐसा इसलिए होता है क्योंकि बहुत अधिक ग्रीनहाउस गैसें हवा छोड़ी जा रही हैं। इससे गर्मी बढ़ जाती है और ग्रह गर्म हो जाता है।  जनसंख्या वृद्धि और वनों की कटाई जैसे कारक भी बड़ी भूमिका निभाते हैं। पेड़ कार्बन डाइऑक्साइड के स्तर को संतुलित करने में मदद करते हैं, इसलिए उन्हें काटने से समस्या और भी बदतर हो जाती है। ग्रीनहाउस प्रभाव एक प्राकृतिक प्रक्रिया है, लेकिन जब बहुत अधिक ग्रीनहाउस गैसें निकलती हैं, तो इससे ग्लोबल वार्मिंग होती है और ओजोन परत को नुकसान पहुंचता है, जो हमें सूरज की हानिकारक किरणों से बचाती है। यदि ग्लोबल वार्मिंग की स्थिति खराब होती रही, तो यह अंततः पृथ्वी पर जीवन के विलुप्त होने का कारण बन सकता है। इनमें से कुछ कारणों को व्यक्तियों द्वारा नियंत्रित किया जा सकता है, जबकि अन्य को समुदायों और विश्व के बड़े नेताओं के प्रयासों की आवश्यकता है। दुनिया भर के वैज्ञानिकों का कहना है कि ग्लोबल वार्मिंग के मुख्य कारण हैं:

• ग्रीनहाउस गैसें: ये गैसें वायुमंडल में गर्मी को रोकती हैं, जिससे पृथ्वी गर्म हो जाती है।
• वनों की कटाई: पेड़ों को काटने से पृथ्वी की ग्रीनहाउस गैस कार्बन डाइऑक्साइड को अवशोषित करने की क्षमता कम हो जाती है।
• प्रदूषण: कारों, कारखानों और अन्य स्रोतों से होने वाला प्रदूषण हवा में हानिकारक गैसें छोड़ता है, जो ग्लोबल वार्मिंग में योगदान देता है।
• प्रति व्यक्ति कार्बन उत्सर्जन: प्रत्येक व्यक्ति का कार्बन पदचिह्न, या वे कितना कार्बन डाइऑक्साइड पैदा करते हैं, ग्लोबल वार्मिंग में योगदान देता है।

ग्लोबल वार्मिंग तब होती है जब पृथ्वी का तापमान लगातार गर्म होता जाता है। ग्लोबल वार्मिंग एक बड़ी समस्या है, लेकिन हम कार्बन उत्सर्जन को कम करके मदद कर सकते हैं। सरकारें इस पर काम कर रही हैं, लेकिन सभी को भी अपनी भूमिका निभानी होगी। हम सभी कम ऊर्जा का उपयोग करके, कम गाड़ी चलाकर और पर्यावरण पर अपने प्रभाव के प्रति अधिक सचेत रहकर बदलाव ला सकते हैं।

ऐसा इसलिए होता है क्योंकि कार्बन मोनोऑक्साइड, कार्बन डाइऑक्साइड और मीथेन जैसी गैसें हवा में छोड़ी जाती हैं। ये गैसें वायुमंडल में गर्मी को रोक लेती हैं, जिससे पृथ्वी गर्म हो जाती है। तापमान में इस वृद्धि के कुछ गंभीर प्रभाव निम्न प्रकार से हैं:

• समुद्र का स्तर बढ़ने से तटीय क्षेत्रों में अधिक बाढ़ आती है।
• वायु प्रदूषण बदतर हो जाता है।
• लू की लहरें अधिक बार और तीव्र हो जाती हैं।
• जंगल में आग लगने की घटनाएं अक्सर होती रहती हैं।
• तूफ़ान, बाढ़ और सूखा जैसे चरम मौसम अधिक बार आते हैं।
• लोगों को सांस लेने में तकलीफ, फेफड़ों में संक्रमण, हीटस्ट्रोक और अंग विफलता जैसी अधिक स्वास्थ्य समस्याओं का अनुभव होता है।

ग्लोबल वार्मिंग एक गंभीर खतरा है जिसके लिए दुनिया भर में व्यक्तियों, समुदायों और सरकारों से तत्काल कार्रवाई की आवश्यकता है। अनियंत्रित ग्लोबल वार्मिंग के परिणाम, जैसे समुद्र के स्तर में वृद्धि, प्रदूषण में वृद्धि, चरम मौसम की घटनाएं और स्वास्थ्य समस्याएं, पहले से ही महसूस की जा रही हैं। इन प्रभावों को कम करने और हमारे ग्रह के लिए एक स्थायी भविष्य सुरक्षित करने के लिए, हमें कार्बन उत्सर्जन को कम करने और स्वच्छ, नवीकरणीय ऊर्जा स्रोतों में परिवर्तन को प्राथमिकता देनी चाहिए। एक साथ काम करके और ग्लोबल वार्मिंग से निपटने के लिए सक्रिय कदम उठाकर, हम अपने पर्यावरण की रक्षा कर सकते हैं, कमजोर समुदायों की रक्षा कर सकते हैं और आने वाली पीढ़ियों के लिए एक स्वस्थ और अधिक टिकाऊ दुनिया सुनिश्चित कर सकते हैं।

ग्लोबल वार्मिंग पर 10 लाइन्स नीचे दी गई है:

• ग्लोबल वार्मिंग का तात्पर्य मानवीय गतिविधियों के कारण पृथ्वी के औसत तापमान में दीर्घकालिक वृद्धि से है।
• कार्बन डाइऑक्साइड, मीथेन और नाइट्रस ऑक्साइड जैसी ग्रीनहाउस गैसें वातावरण में गर्मी को रोकती हैं, जिससे ग्लोबल वार्मिंग होती है।
• मानवीय गतिविधियाँ जैसे जीवाश्म ईंधन जलाना, वनों की कटाई और औद्योगिक प्रक्रियाएँ ग्रीनहाउस गैसों की रिहाई में योगदान करती हैं।
• ग्लोबल वार्मिंग के परिणाम के रूप में समुद्र के स्तर में वृद्धि होती है, बर्फ की परतें पिघलती हैं, अधिक लगातार और तीव्र गर्मी की लहरें चलती हैं और मौसम के पैटर्न में बदलाव होता है।
• ग्लोबल वार्मिंग के कारण तूफान, बाढ़ और सूखा जैसी चरम मौसमी घटनाएं आम होती जा रही हैं।
• ग्लोबल वार्मिंग पारिस्थितिकी तंत्र, जैव विविधता और मानव स्वास्थ्य के लिए गंभीर खतरा पैदा करती है।
• ग्लोबल वार्मिंग को कम करने के लिए ग्रीनहाउस गैस उत्सर्जन को कम करने और नवीकरणीय ऊर्जा स्रोतों में परिवर्तन के लिए सामूहिक कार्रवाई की आवश्यकता है।
• ग्लोबल वार्मिंग की वजह से दुनिया भर के मौसमों में बदलाव महसूस किया जा रहा है।
• ग्लोबल वार्मिंग के प्रभावों को कम करने के लिए प्रभावी नीतियों और रणनीतियों को विकसित करने और लागू करने के लिए अंतर्राष्ट्रीय सहयोग आवश्यक है।
• भविष्य की पीढ़ियों के लिए ग्रह की सुरक्षा के लिए कार्बन उत्सर्जन को कम करने और बदलती जलवायु के अनुकूल कदम उठाना महत्वपूर्ण है।

ग्लोबल वार्मिंग मुख्य रूप से वायुमंडल में कार्बन डाइऑक्साइड (CO2), मीथेन (CH4), और नाइट्रस ऑक्साइड (N2O) जैसी ग्रीनहाउस गैसों की रिहाई के कारण होती है। ये गैसें सूर्य की गर्मी को सोख लेती हैं, जिससे पृथ्वी के औसत तापमान में धीरे-धीरे वृद्धि होती है।

ग्लोबल वार्मिंग के परिणामों में समुद्र के स्तर में वृद्धि, बर्फ की चोटियों और ग्लेशियरों का पिघलना, अधिक लगातार और तीव्र गर्मी की लहरें, वर्षा के पैटर्न में बदलाव शामिल है। इसके साथ पारिस्थितिक तंत्र और वन्यजीव आवासों में व्यवधान, तूफान और सूखे जैसी मौसम की घटनाओं में वृद्धि और मानव के लिए खतरा शामिल हैं। 

मानवीय गतिविधियाँ, जैसे ऊर्जा के लिए जीवाश्म ईंधन जलाना, वनों की कटाई, औद्योगिक प्रक्रियाएँ और कृषि पद्धतियाँ, वायुमंडल में बड़ी मात्रा में ग्रीनहाउस गैसें छोड़ती हैं।  इन गतिविधियों से ग्रीनहाउस गैसों की सांद्रता बढ़ती है, जिससे ग्रीनहाउस प्रभाव बढ़ता है और पृथ्वी का तापमान बढ़ता है।

ग्लोबल वार्मिंग से निपटने के लिए व्यक्ति और समुदाय विभिन्न कदम उठा सकते हैं। इसमें ऊर्जा की खपत को कम करना, नवीकरणीय ऊर्जा स्रोतों का उपयोग करना, ऊर्जा-कुशल प्रौद्योगिकियों को अपनाना शामिल है। अपशिष्ट को कम करना, पानी का संरक्षण, टिकाऊ परिवहन विकल्पों को अपनाना, पेड़ लगाना आवश्यक है। ग्रीनहाउस गैस उत्सर्जन, और जलवायु परिवर्तन से निपटने के महत्व के बारे में जागरूकता बढ़ाना भी महत्वपूर्ण है।

Essay on Global Warming – 10 Lines, Short and Long Essay For Children

Key Points To Remember When Writing An Essay On Global Warming For Lower Primary Classes

10 lines on ‘global warming’ for kids, paragraph on ‘global warming’ for children, short essay on global warming in 250 words for kids, long essay on global warming for children, what will your child learn from the essay on global warming.

Global warming is the brutal reality of our times, resulting in climate change. Global warming is threatening the existence of our planet and every living species on it. According to researchers, global warming also endangers marine life’s presence. Kids need to know about this threat in their early years to make small but impactful changes in their approach to the planet’s survival. Writing an essay on global warming   will allow kids to analyse this issue with a fresh perspective. Given in this blog is an   essay for classes 1, 2 and 3 on this important topic.

Global warming is a massive problem, so teachers and parents ask kids to write about this serious issue to make them aware of it. Given below are key points that will answer their question about  how to write an essay on global warming:

• There should be an introduction describing global warming.
• The body of the essay should cover points like its impact, causes, precautions, etc.
• The conclusion should mention the summary of all the points mentioned above.
• If a kid writes, their point of view on the whole problem is crucial.
• Make short and simple sentences.

When writing about an important topic like global warming, teachers expect students in junior classes to write short sentences for better clarity. Given below are a  few lines on global warming  for writing an  essay for classes 1 and 2:

• Global warming can be defined as the rise in the surface temperature of the earth.
• The main reason behind global warming is the greenhouse effect.
• The depletion of green cover and the increase of gases like CO2 in the atmosphere is leading to global warming.
• Climate change is caused due to global warming, among other factors.
• Climate change leads to situations like droughts and disturbances in monsoon patterns.
• The mindless use of natural resources is another reason for global warming.
• An increase in global temperature leads to melting glaciers, resulting in a rise in sea level.
• Due to global warming temperature of the sea/water is also increasing. Thus, affecting marine life.
• We can prevent global warming by planting more trees and controlling the emission of harmful gases into the atmosphere.
• We need to understand that every activity that harms nature supports global warming.

Global warming is a crucial problem our planet faces due to humans’ mindless actions, and this is something kids need to understand at an early age. Given below is an essay on  global warming in 100 words for their reference:

In simple words, global warming means a rise in the earth’s average temperature. The main reason contributing to global warming is the greenhouse effect. The primary effect can be seen on our glaciers, as they are melting and raising the sea level, affecting human existence. The rise in water temperature is affecting marine life, and climate change triggered by global warming is creating extreme weather conditions. Deforestation and mindless use of our natural resources are some factors behind global warming. We must stop activities harming our nature’s balance to control global warming.

Writing on topics like global warming enhances thinking and evaluating abilities. Given below is an essay for classes 1, 2 and 3 on global warming for their reference:

We are living in an age where there are many threats to the existence of our beautiful planet. But, the most crucial one is global warming. It is a concern among many intellectuals, politicians, researchers, policymakers, geographical experts, etc., as it endangers living beings’ very survival. So, what is global warming? The continuous rise in the temperature of the earth is called global warming. It is said that the earth’s temperature has risen by 0.08 degrees celsius every ten years since 1880. The leading cause behind global warming is human’s careless and excessive use of natural resources. The depletion of green cover and the rise in the greenhouse gases like CO2 in the atmosphere are other factors behind global warming. The primary effect on the planet due to global warming is climate change. We observe a drastic shift in monsoon patterns every year and experience drought and floods like calamities. Many other notable changes are happening due to global warming. For example, heat waves have increased, some crucial animals have extincted, the effect on marine life is relentless, our glaciers have shrunk, and many more. We need to understand this and work on ways to improve the living quality on earth. Initiatives like planting trees, adopting spaces and making them sustainable are ways to improve this world. Even small things like cycling to school instead of using the car or public transport are a small way we can make a difference. 

Global warming is such a sensitive issue that needs to be addressed faster. Our future generations are going to play a significant role in the same. So, given below is an essay for class 3 on global warming.

Nature has given us so much to use, enjoy, explore and value. But our greed has destroyed everything- the very purpose of this beautiful earth. Now, we are on the edge of destruction as nature has started showing signs of floods, earthquakes, droughts, etc. But, one of the major challenges we are facing now is global warming, and all the points mentioned above are the outcome of this issue.

What Is Global Warming?

In simple words, global warming is the gradual increase in the earth’s temperature due to the greenhouse effect. The greenhouse effect or greenhouse gases like CO2, methane, etc., are good for the planet as these gases capture the heat from the sun and keep the atmosphere warm and liveable for living beings, but an increase in these greenhouse gases leads to more heat trap on earth which causes unnecessary earth heat up and lead to global warming.

What Are The Causes And Effects Of Global Warming?

There are many causes and effects of global warming – 

Causes of Global Warming

• Greenhouse effect or greenhouse gases:  Global warming happens when increased greenhouse gases like CO2, methane, and other pollutants absorb the sun’s heat more than the requirement and make the planet hotter.
• Volcanic eruptions:  These eruptions increase carbon dioxide, leading to global warming.
• Excessive use of automobiles: Excessive vehicles on the road lead to unnecessary emission of carbon dioxide gas into the environment, which is responsible for global warming.
• Deforestation:  The careless cutting of forest for building houses and sky-rises is depleting our green cover. So the absorption of carbon dioxide is decreasing, leading to global warming.
• Fossil fuel burning:  Excessive fossil fuel burning leads to unwanted carbon dioxide emissions in the atmosphere. Again, contribution to global warming.

Effects of global warming

• Climate change:  Researchers agree that climate change is happening due to global warming. Earth’s rising temperature triggers heat waves, excessive rainfall, frequent droughts, etc.
• Disappearing glaciers:  Due to the rising temperature of the earth, glaciers are melting rapidly, resulting in rising sea levels.
• Extinct animals:  Many animals and birds go extinct due to unfavourable climatic conditions.
• Hampered agriculture:  Heavy rainfall in some places, drought in others, and heat waves destroy agriculture.

How Can Global Warming Be Prevented?

• Plant more trees:  A collective plantation drive should be initiated to compensate for the green cover. More trees and less CO2 in the environment can lead to controlled global warming.
• Take public transport:  Take public transport whenever possible. Don’t use private vehicles for luxury. This way, fewer greenhouse gases will get emitted into the atmosphere, reducing global warming.
• Save energy:  Use energy-sufficient appliances at home. Energy efficiency is the most cost-effective way to lessen unwanted environmental emissions.
• Conserve natural resources:  We need to stop the irrelevant overuse of our natural resources, which include water, soil, fossils, etc., for a better future and controlled global warming.

By writing an essay on global warming, your child learns about this global concern in detail, and may understand the importance of keeping things in check. They may contribute to taking preventive measures to stop global warming.
