effects of global warming essay 250 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?

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.

Global Warming Essay

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.

Our Future Is Now - A Climate Change Essay by Francesca Minicozzi, '21

Francesca Minicozzi (class of 2021) is a Writing/Biology major who plans to study medicine after graduation. She wrote this essay on climate change for WR 355/Travel Writing, which she took while studying abroad in Newcastle in spring 2020. Although the coronavirus pandemic curtailed Francesca’s time abroad, her months in Newcastle prompted her to learn more about climate change. Terre Ryan Associate Professor, Writing Department

Our Future Is Now

By Francesca Minicozzi, '21 Writing and Biology Major

“If you don’t mind me asking, how is the United States preparing for climate change?” my flat mate, Zac, asked me back in March, when we were both still in Newcastle. He and I were accustomed to asking each other about the differences between our home countries; he came from Cambridge, while I originated in Long Island, New York. This was one of our numerous conversations about issues that impact our generation, which we usually discussed while cooking dinner in our communal kitchen. In the moment of our conversation, I did not have as strong an answer for him as I would have liked. Instead, I informed him of the few changes I had witnessed within my home state of New York.

Zac’s response was consistent with his normal, diplomatic self. “I have been following the BBC news in terms of the climate crisis for the past few years. The U.K. has been working hard to transition to renewable energy sources. Similar to the United States, here in the United Kingdom we have converted over to solar panels too. My home does not have solar panels, but a lot of our neighbors have switched to solar energy in the past few years.”

“Our two countries are similar, yet so different,” I thought. Our conversation continued as we prepared our meals, with topics ranging from climate change to the upcoming presidential election to Britain’s exit from the European Union. However, I could not shake the fact that I knew so little about a topic so crucial to my generation.

After I abruptly returned home from the United Kingdom because of the global pandemic, my conversation with my flat mate lingered in my mind. Before the coronavirus surpassed climate change headlines, I had seen the number of internet postings regarding protests to protect the planet dramatically increase. Yet the idea of our planet becoming barren and unlivable in a not-so-distant future had previously upset me to the point where a part of me refused to deal with it. After I returned from studying abroad, I decided to educate myself on the climate crisis.

My quest for climate change knowledge required a thorough understanding of the difference between “climate change” and “global warming.” Climate change is defined as “a pattern of change affecting global or regional climate,” based on “average temperature and rainfall measurements” as well as the frequency of extreme weather events. 1 These varied temperature and weather events link back to both natural incidents and human activity. 2 Likewise, the term global warming was coined “to describe climate change caused by humans.” 3 Not only that, but global warming is most recently attributed to an increase in “global average temperature,” mainly due to greenhouse gas emissions produced by humans. 4

I next questioned why the term “climate change” seemed to take over the term “global warming” in the United States. According to Frank Luntz, a leading Republican consultant, the term “global warming” functions as a rather intimidating phrase. During George W. Bush’s first presidential term, Luntz argued in favor of using the less daunting phrase “climate change” in an attempt to overcome the environmental battle amongst Democrats and Republicans. 5 Since President Bush’s term, Luntz remains just one political consultant out of many politicians who has recognized the need to address climate change. In an article from 2019, Luntz proclaimed that political parties aside, the climate crisis affects everyone. Luntz argued that politicians should steer clear of trying to communicate “the complicated science of climate change,” and instead engage voters by explaining how climate change personally impacts citizens with natural disasters such as hurricanes, tornadoes, and forest fires. 6 He even suggested that a shift away from words like “sustainability” would gear Americans towards what they really want: a “cleaner, safer, healthier” environment. 7

The idea of a cleaner and heathier environment remains easier said than done. The Paris Climate Agreement, introduced in 2015, began the United Nations’ “effort to combat global climate change.” 8 This agreement marked a global initiative to “limit global temperature increase in this century to 2 degrees Celsius above preindustrial levels,” while simultaneously “pursuing means to limit the increase to 1.5 degrees.” 9 Every country on earth has joined together in this agreement for the common purpose of saving our planet. 10 So, what could go wrong here? As much as this sounds like a compelling step in the right direction for climate change, President Donald Trump thought otherwise. In June 2017, President Trump announced the withdrawal of the United States from the Paris Agreement with his proclamation of climate change as a “’hoax’ perpetrated by China.” 11 President Trump continued to question the scientific facts behind climate change, remaining an advocate for the expansion of domestic fossil fuel production. 12 He reversed environmental policies implemented by former President Barack Obama to reduce fossil fuel use. 13

Trump’s actions against the Paris Agreement, however, fail to represent the beliefs of Americans as a whole. The majority of American citizens feel passionate about the fight against climate change. To demonstrate their support, some have gone as far as creating initiatives including America’s Pledge and We Are Still In. 14 Although the United States officially exited the Paris Agreement on November 4, 2020, this withdrawal may not survive permanently. 15 According to experts, our new president “could rejoin in as short as a month’s time.” 16 This offers a glimmer of hope.

The Paris Agreement declares that the United States will reduce greenhouse gas emission levels by 26 to 28 percent by the year 2025. 17 As a leader in greenhouse gas emissions, the United States needs to accept the climate crisis for the serious challenge that it presents and work together with other nations. The concept of working coherently with all nations remains rather tricky; however, I remain optimistic. I think we can learn from how other countries have adapted to the increased heating of our planet. During my recent study abroad experience in the United Kingdom, I was struck by Great Britain’s commitment to combating climate change.

Since the United Kingdom joined the Paris Agreement, the country targets a “net-zero” greenhouse gas emission for 2050. 18 This substantial alteration would mark an 80% reduction of greenhouse gases from 1990, if “clear, stable, and well-designed policies are implemented without interruption.” 19 In order to stay on top of reducing emissions, the United Kingdom tracks electricity and car emissions, “size of onshore and offshore wind farms,” amount of homes and “walls insulated, and boilers upgraded,” as well as the development of government policies, including grants for electric vehicles. 20 A strong grip on this data allows the United Kingdom to target necessary modifications that keep the country on track for 2050. In my brief semester in Newcastle, I took note of these significant changes. The city of Newcastle is small enough that many students and faculty are able to walk or bike to campus and nearby essential shops. However, when driving is unavoidable, the majority of the vehicles used are electric, and many British citizens place a strong emphasis on carpooling to further reduce emissions. The United Kingdom’s determination to severely reduce greenhouse emissions is ambitious and particularly admirable, especially as the United States struggles to shy away from its dependence on fossil fuels.

So how can we, as Americans, stand together to combat global climate change? Here are five adjustments Americans can make to their homes and daily routines that can dramatically make a difference:

Stay cautious of food waste. Studies demonstrate that “Americans throw away up to 40 percent of the food they buy.” 21 By being more mindful of the foods we purchase, opting for leftovers, composting wastes, and donating surplus food to those in need, we can make an individual difference that impacts the greater good. 22
Insulate your home. Insulation functions as a “cost-effective and accessible” method to combat climate change. 23 Homes with modern insulation reduce energy required to heat them, leading to a reduction of emissions and an overall savings; in comparison, older homes can “lose up to 35 percent of heat through their walls.” 24
Switch to LED Lighting. LED stands for “light-emitting diodes,” which use “90 percent less energy than incandescent bulbs and half as much as compact fluorescents.” 25 LED lights create light without producing heat, and therefore do not waste energy. Additionally, these lights have a longer duration than other bulbs, which means they offer a continuing savings. 26
Choose transportation wisely. Choose to walk or bike whenever the option presents itself. If walking or biking is not an option, use an electric or hybrid vehicle which emits less harmful gases. Furthermore, reduce the number of car trips taken, and carpool with others when applicable.
Finally, make your voice heard. The future of our planet remains in our hands, so we might as well use our voices to our advantage. Social media serves as a great platform for this. Moreover, using social media to share helpful hints to combat climate change within your community or to promote an upcoming protest proves beneficial in the long run. If we collectively put our voices to good use, together we can advocate for change.

As many of us are stuck at home due to the COVID-19 pandemic, these suggestions are slightly easier to put into place. With numerous “stay-at-home” orders in effect, Americans have the opportunity to make significant achievements for climate change. Personally, I have taken more precautions towards the amount of food consumed within my household during this pandemic. I have been more aware of food waste, opting for leftovers when too much food remains. Additionally, I have realized how powerful my voice is as a young college student. Now is the opportunity for Americans to share how they feel about climate change. During this unprecedented time, our voice is needed now more than ever in order to make a difference.

However, on a much larger scale, the coronavirus outbreak has shed light on reducing global energy consumption. Reductions in travel, both on the roads and in the air, have triggered a drop in emission rates. In fact, the International Energy Agency predicts a 6 percent decrease in energy consumption around the globe for this year alone. 27 This drop is “equivalent to losing the entire energy demand of India.” 28 Complete lockdowns have lowered the global demand for electricity and slashed CO2 emissions. However, in New York City, the shutdown has only decreased carbon dioxide emissions by 10 percent. 29 This proves that a shift in personal behavior is simply not enough to “fix the carbon emission problem.” 30 Climate policies aimed to reduce fossil fuel production and promote clean technology will be crucial steppingstones to ameliorating climate change effects. Our current reduction of greenhouse gas emissions serves as “the sort of reduction we need every year until net-zero emissions are reached around 2050.” 31 From the start of the coronavirus pandemic, politicians came together for the common good of protecting humanity; this demonstrates that when necessary, global leaders are capable of putting humankind above the economy. 32

After researching statistics comparing the coronavirus to climate change, I thought back to the moment the virus reached pandemic status. I knew that a greater reason underlay all of this global turmoil. Our globe is in dire need of help, and the coronavirus reminds the world of what it means to work together. This pandemic marks a turning point in global efforts to slow down climate change. The methods we enact towards not only stopping the spread of the virus, but slowing down climate change, will ultimately depict how humanity will arise once this pandemic is suppressed. The future of our home planet lies in how we treat it right now.

Climate Change Essay

500+ words essay on climate change.

Climate change is a major global challenge today, and the world is becoming more vulnerable to this change. Climate change refers to the changes in Earth’s climate condition. It describes the changes in the atmosphere which have taken place over a period ranging from decades to millions of years. A recent report from the United Nations predicted that the average global temperature could increase by 6˚ Celsius at the end of the century. Climate change has an adverse effect on the environment and ecosystem. With the help of this essay, students will get to know the causes and effects of climate change and possible solutions. Also, they will be able to write essays on similar topics and can boost their writing skills.

What Causes Climate Change?

The Earth’s climate has always changed and evolved. Some of these changes have been due to natural causes such as volcanic eruptions, floods, forest fires etc., but quite a few of them are due to human activities. Human activities such as deforestation, burning fossil fuels, farming livestock etc., generate an enormous amount of greenhouse gases. This results in the greenhouse effect and global warming which are the major causes of climate change.

Effects of Climate Change

If the current situation of climate change continues in a similar manner, then it will impact all forms of life on the earth. The earth’s temperature will rise, the monsoon patterns will change, sea levels will rise, and storms, volcanic eruptions and natural disasters will occur frequently. The biological and ecological balance of the earth will get disturbed. The environment will get polluted and humans will not be able to get fresh air to breathe and fresh water to drink. Life on earth will come to an end.

Steps to be Taken to Reduce Climate Change

The Government of India has taken many measures to improve the dire situation of Climate Change. The Ministry of Environment and Forests is the nodal agency for climate change issues in India. It has initiated several climate-friendly measures, particularly in the area of renewable energy. India took several steps and policy initiatives to create awareness about climate change and help capacity building for adaptation measures. It has initiated a “Green India” programme under which various trees are planted to make the forest land more green and fertile.

We need to follow the path of sustainable development to effectively address the concerns of climate change. We need to minimise the use of fossil fuels, which is the major cause of global warming. We must adopt alternative sources of energy, such as hydropower, solar and wind energy to make a progressive transition to clean energy. Mahatma Gandhi said that “Earth provides enough to satisfy every man’s need, but not any man’s greed”. With this view, we must remodel our outlook and achieve the goal of sustainable development. By adopting clean technologies, equitable distribution of resources and addressing the issues of equity and justice, we can make our developmental process more harmonious with nature.

We hope students liked this essay on Climate Change and gathered useful information on this topic so that they can write essays in their own words. To get more study material related to the CBSE, ICSE, State Board and Competitive exams, keep visiting the BYJU’S website.

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.

Paragraph On 'Global Warming' For Children

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.

global warming summary

Learn about the causes and effects of global warming.

global warming , Increase in the global average surface temperature resulting from enhancement of the greenhouse effect, primarily by air pollution . In 2007 the UN Intergovernmental Panel on Climate Change forecast that by 2100 global average surface temperatures would increase 3.2–7.2 °F (1.8–4.0 °C), depending on a range of scenarios for greenhouse gas emissions, and stated that it was now 90 percent certain that most of the warming observed over the previous half century could be attributed to greenhouse gas emissions produced by human activities (i.e., industrial processes and transportation). Many scientists predict that such an increase in temperature would cause polar ice caps and mountain glaciers to melt rapidly, significantly raising the levels of coastal waters, and would produce new patterns and extremes of drought and rainfall, seriously disrupting food production in certain regions. Other scientists maintain that such predictions are overstated. The 1992 Earth Summit and the 1997 Kyoto Protocol to the United Nations Framework Convention on Climate Change attempted to address the issue of global warming, but in both cases the efforts were hindered by conflicting national economic agendas and disputes between developed and developing nations over the cost and consequences of reducing emissions of greenhouse gases.

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 Definition, Causes, Effects, Impacts, Solutions_4.1

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.

Sharing is caring!

Why is global warming a problem?

Global Warming at present rate can lead to disastrous impacts like rising sea level, out break of new diseases, extreme weather events among others.

What are 3 causes of global warming?

Human induced green house gas emission due to activities like agriculture, industrial emissions, transportation are the top 3 causes of global warming.

What are 5 effects of global warming?

Rising sea level, out break of new diseases, extreme weather events, changes in biodiversity and melting of glaciers are top 5 effects of global warming.

Why global warming is important?

Global warming at its natural rate is important to keep up the temperature of earth within the range that makes it habitable. This makes global warming important.

Can we control global warming?

Number of mitigation measures like shifting to cleaning forms of energy and transportation can be taken to control global warming.

Who help with global warming?

Global Warming is a collective challenge for entire humanity. Citizens, civil societies, governments and businesses must act in unison to address it.

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

Updated on
Feb 3, 2024

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

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

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

Quick Read: 2-Minute Speech on Holi

This Blog Includes:

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

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

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

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