Short Essay on Global Warming of 100 Words

The increasing rise in average global temperatures on earth measured over a long period is termed as Global Warming. The rise in the level of carbon dioxide in the atmosphere is one of the leading cause, to a cumulative increase in temperature. Due to mass deforestation activities by humans has accelerated global warming.

Plants to prepare their food uses carbon dioxide and as a by-product releases oxygen. As, plants has the ability absorb the excess carbon dioxide from the atmosphere which eventually can decrease the rate of global warming to some extent. Planting more trees can reduce the carbon dioxide levels in the atmosphere and will result in a decrease in global warming.

 Short Essay on Global Warming of 150 Words

A rapid hike in the average global temperature on earth is termed as global warming. The release of toxic fumes and burning of excess fossil fuel into the atmosphere is one of the major cause behind global warming.

It can have disastrous effects on our planet and living organisms. The impacts of global warming are unspecific and widespread. Some areas witness a sudden fall in it while others experience a sudden rise in the temperature.

The primary reason causing global warming is the burning of fuel from fossils for energy. Global warming is a reason for worry as it can damage ecosystems and might result in the disruption of the environment.

If people starts taking concrete steps towards restoring the lost vegetation in our forests, global warming can be reduce and put a check. We can also use clean energy sources like solar energy,tidal energy and wind energy to check the rise in global warming.

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.

Essay on global warming is an important topic for students to understand. The essay brings to light the plight of the environment and the repercussion of anthropogenic activities. Continue reading to discover tips and tricks for writing an engaging and interesting essay on global warming.

Essay On Global Warming in 300 Words

Global warming is a phenomenon where the earth’s average temperature rises due to increased amounts of greenhouse gases. Greenhouse gases such as carbon dioxide, methane and ozone trap the incoming radiation from the sun. This effect creates a natural “blanket”, which prevents the heat from escaping back into the atmosphere. This effect is called the greenhouse effect.

Contrary to popular belief, greenhouse gases are not inherently bad. In fact, the greenhouse effect is quite important for life on earth. Without this effect, the sun’s radiation would be reflected back into the atmosphere, freezing the surface and making life impossible. However, when greenhouse gases in excess amounts get trapped, serious repercussions begin to appear. The polar ice caps begin to melt, leading to a rise in sea levels. Furthermore, the greenhouse effect is accelerated when polar ice caps and sea ice melts. This is due to the fact the ice reflects 50% to 70% of the sun’s rays back into space, but without ice, the solar radiation gets absorbed. Seawater reflects only 6% of the sun’s radiation back into space. What’s more frightening is the fact that the poles contain large amounts of carbon dioxide trapped within the ice. If this ice melts, it will significantly contribute to global warming. 

A related scenario when this phenomenon goes out of control is the runaway-greenhouse effect. This scenario is essentially similar to an apocalypse, but it is all too real. Though this has never happened in the earth’s entire history, it is speculated to have occurred on Venus. Millions of years ago, Venus was thought to have an atmosphere similar to that of the earth. But due to the runaway greenhouse effect, surface temperatures around the planet began rising. 

If this occurs on the earth, the runaway greenhouse effect will lead to many unpleasant scenarios – temperatures will rise hot enough for oceans to evaporate. Once the oceans evaporate, the rocks will start to sublimate under heat. In order to prevent such a scenario, proper measures have to be taken to stop climate change.

Essay on Effects of Global Warming for Students and Children

500+ words essay on effects of global warming.

Global warming refers to climate change that causes an increase in the average of Earth’s temperature. Natural events and human influences are believed to be top contributions towards the increase in average temperatures. Global warming is a rise in the surface and atmospheric temperature of the earth that has changed various life forms on the earth. The issues that ascertain global warming are divided into two broad categories – “natural” and “human influences” of global warming.

Natural Causes of Global Warming

The climate has been continuously changing for centuries. One natural cause of global warming is greenhouse gases. Greenhouse gases are carbon monoxide and sulphur dioxide . It traps the solar rays and prevents them from escaping the surface of the earth.

This causes an increase in the temperature of the earth. Volcanic eruptions are another reason for global warming. A single volcanic eruption can release a great amount of carbon dioxide and ash to the atmosphere. Increased carbon dioxide leads to a rise in the temperature of the earth.

Also, methane gas is another contributor to global warming. Methane is also a greenhouse gas. Methane is twenty times more effective in trapping heat in the atmosphere than carbon dioxide. Usually, methane gas is released from many areas like animal waste, landfill, natural gas, and others.

Human Influences on Global Warming

Human influence has been a very serious issue now as it is contributing more than natural causes of global warming. Since human evolution, the earth has been changing for many years until now and it is still changing because of our modern lifestyle. Human activities include industrial production, burning fossil fuel, mining of minerals, cattle rearing and deforestation.

Industries, transportation such as cars, buses, trucks burn fuel to power machines, which eventually releases carbon dioxide and monoxide from the exhaust, leading to an increase in a temperature rise of Earth’s atmosphere.

Another contributor is mining. During the process of mining, the methane gas trapped below the earth escapes. Rearing cattle also causes the release of methane from manure. Another cause is the most common but most dangerous – deforestation.

Deforestation is a human influence because human have been cutting down trees to produce paper, wood, build houses and more. Trees can absorb carbon dioxide from the atmosphere and their absence can lead to the concentration of such gases.

The Effect of Global Warming

The impact that global warming is causing on earth is extremely serious. There are many hazardous effects that will happen in the future if global warming continues. It includes melting of polar ice caps, leading to an increase in sea level drowning coastlines and slowly submerging continents.

Recent studies by National Snow and Ice Datacenter “if the ice melted today the seas would rise about 230 feet”. Another effect is climate change leading to the extinction of various species. More hurricanes, cyclonic storms, heat waves, drought, and extreme rainfalls will occur causing disaster to humankind.

The solution to Stop Global Warming

We humans need to work together towards the prevention of global warming. To reduce global warming we can contribute by reducing the production and concentration of greenhouse gases in the atmosphere. We need to curb usage of gasoline, electricity and other activities including mining and industrialization that cause global warming.

Another way to reduce global warming is through recycling. Recycling can help reduce open burning of garbage by reusing plastic bags, bottles, papers or glass. We need to stop open burning dry leaves or burning garbage. It contributes to releasing carbon dioxide and toxins. Besides, we should reduce deforestation and start planting more trees. Trees will help improve the temperature on earth and prevent drastic climatic change.

From today’s scenario, we can derive that our earth is “sick” and we humans need to “heal” it. Global Warming has already caused many problems for human and we need to prevent disasters of the future. Our generation needs to take care of the earth with immediate effect to safeguard future generations or they will suffer the consequences of global warming.

Lesson of the Day

Explore 7 Climate Change Solutions

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

By Natalie Proulx

Lesson Overview

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

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

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

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

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

Introduction.

Greenhouse Effect

To understand global warming, it helps to understand the greenhouse effect . A greenhouse is a glass house where plants grow. Glass lets light in and keeps heat from escaping. This trapped heat keeps the plants warm even when it is cold outside.

Likewise, Earth’s atmosphere traps energy from the Sun. Carbon dioxide and other gases—called greenhouse gases—in the air do this trapping. Without these gases too much heat would go back into space, and living things could not survive. However, as more greenhouse gases get into the air, they also trap more heat. This leads to global warming.

For much of Earth’s history, greenhouse gases were not a problem. This situation changed as people came to depend on fossil fuels (oil, gas, and coal). People burn fossil fuels to power factories, run cars, produce electricity, and heat houses. As fossil fuels burn, they release carbon dioxide into the atmosphere.

Also, people have cut down many forests. Trees use carbon dioxide when they make their own food. Fewer trees mean that less carbon dioxide is being taken out of the atmosphere.

Reasons for Concern

Scientists cannot tell how warm Earth may get over time. Some guess an increase between 3.2° F and 7.2° F (1.8° C and 4° C) by the year 2100. The warmer weather could harm living things. It also could cause polar ice caps to melt. This would cause sea levels to rise. Plants, animals, and buildings along coastlines would be in danger.

Stopping Global Warming

Global warming is a worldwide concern. Governments are trying to find ways to limit the amount of greenhouse gases put into the air. Individual people can help by driving less. They also can save energy by turning off unneeded lights and other electrical devices.

Human activity affects global surface temperatures by changing Earth ’s radiative balance—the “give and take” between what comes in during the day and what Earth emits at night. Increases in greenhouse gases —i.e., trace gases such as carbon dioxide and methane that absorb heat energy emitted from Earth’s surface and reradiate it back—generated by industry and transportation cause the atmosphere to retain more heat, which increases temperatures and alters precipitation patterns.

Global warming, the phenomenon of increasing average air temperatures near Earth’s surface over the past one to two centuries, happens mostly in the troposphere , the lowest level of the atmosphere, which extends from Earth’s surface up to a height of 6–11 miles. This layer contains most of Earth’s clouds and is where living things and their habitats and weather primarily occur.

Continued global warming is expected to impact everything from energy use to water availability to crop productivity throughout the world. Poor countries and communities with limited abilities to adapt to these changes are expected to suffer disproportionately. Global warming is already being associated with increases in the incidence of severe and extreme weather, heavy flooding , and wildfires —phenomena that threaten homes, dams, transportation networks, and other facets of human infrastructure. Learn more about how the IPCC’s Sixth Assessment Report, released in 2021, describes the social impacts of global warming.

Polar bears live in the Arctic , where they use the region’s ice floes as they hunt seals and other marine mammals . Temperature increases related to global warming have been the most pronounced at the poles, where they often make the difference between frozen and melted ice. Polar bears rely on small gaps in the ice to hunt their prey. As these gaps widen because of continued melting, prey capture has become more challenging for these animals.

Recent News

global warming , the phenomenon of increasing average air temperatures near the surface of Earth over the past one to two centuries. Climate scientists have since the mid-20th century gathered detailed observations of various weather phenomena (such as temperatures, precipitation , and storms) and of related influences on climate (such as ocean currents and the atmosphere’s chemical composition). These data indicate that Earth’s climate has changed over almost every conceivable timescale since the beginning of geologic time and that human activities since at least the beginning of the Industrial Revolution have a growing influence over the pace and extent of present-day climate change .

Giving voice to a growing conviction of most of the scientific community , the Intergovernmental Panel on Climate Change (IPCC) was formed in 1988 by the World Meteorological Organization (WMO) and the United Nations Environment Program (UNEP). The IPCC’s Sixth Assessment Report (AR6), published in 2021, noted that the best estimate of the increase in global average surface temperature between 1850 and 2019 was 1.07 °C (1.9 °F). An IPCC special report produced in 2018 noted that human beings and their activities have been responsible for a worldwide average temperature increase between 0.8 and 1.2 °C (1.4 and 2.2 °F) since preindustrial times, and most of the warming over the second half of the 20th century could be attributed to human activities.

AR6 produced a series of global climate predictions based on modeling five greenhouse gas emission scenarios that accounted for future emissions, mitigation (severity reduction) measures, and uncertainties in the model projections. Some of the main uncertainties include the precise role of feedback processes and the impacts of industrial pollutants known as aerosols , which may offset some warming. The lowest-emissions scenario, which assumed steep cuts in greenhouse gas emissions beginning in 2015, predicted that the global mean surface temperature would increase between 1.0 and 1.8 °C (1.8 and 3.2 °F) by 2100 relative to the 1850–1900 average. This range stood in stark contrast to the highest-emissions scenario, which predicted that the mean surface temperature would rise between 3.3 and 5.7 °C (5.9 and 10.2 °F) by 2100 based on the assumption that greenhouse gas emissions would continue to increase throughout the 21st century. The intermediate-emissions scenario, which assumed that emissions would stabilize by 2050 before declining gradually, projected an increase of between 2.1 and 3.5 °C (3.8 and 6.3 °F) by 2100.

Many climate scientists agree that significant societal, economic, and ecological damage would result if the global average temperature rose by more than 2 °C (3.6 °F) in such a short time. Such damage would include increased extinction of many plant and animal species, shifts in patterns of agriculture , and rising sea levels. By 2015 all but a few national governments had begun the process of instituting carbon reduction plans as part of the Paris Agreement , a treaty designed to help countries keep global warming to 1.5 °C (2.7 °F) above preindustrial levels in order to avoid the worst of the predicted effects. Whereas authors of the 2018 special report noted that should carbon emissions continue at their present rate, the increase in average near-surface air temperature would reach 1.5 °C sometime between 2030 and 2052, authors of the AR6 report suggested that this threshold would be reached by 2041 at the latest.

The AR6 report also noted that the global average sea level had risen by some 20 cm (7.9 inches) between 1901 and 2018 and that sea level rose faster in the second half of the 20th century than in the first half. It also predicted, again depending on a wide range of scenarios, that the global average sea level would rise by different amounts by 2100 relative to the 1995–2014 average. Under the report’s lowest-emission scenario, sea level would rise by 28–55 cm (11–21.7 inches), whereas, under the intermediate emissions scenario, sea level would rise by 44–76 cm (17.3–29.9 inches). The highest-emissions scenario suggested that sea level would rise by 63–101 cm (24.8–39.8 inches) by 2100.

The scenarios referred to above depend mainly on future concentrations of certain trace gases, called greenhouse gases , that have been injected into the lower atmosphere in increasing amounts through the burning of fossil fuels for industry, transportation , and residential uses. Modern global warming is the result of an increase in magnitude of the so-called greenhouse effect , a warming of Earth’s surface and lower atmosphere caused by the presence of water vapour , carbon dioxide , methane , nitrous oxides , and other greenhouse gases. In 2014 the IPCC first reported that concentrations of carbon dioxide, methane, and nitrous oxides in the atmosphere surpassed those found in ice cores dating back 800,000 years.

Of all these gases, carbon dioxide is the most important, both for its role in the greenhouse effect and for its role in the human economy. It has been estimated that, at the beginning of the industrial age in the mid-18th century, carbon dioxide concentrations in the atmosphere were roughly 280 parts per million (ppm). By the end of 2022 they had risen to 419 ppm, and, if fossil fuels continue to be burned at current rates, they are projected to reach 550 ppm by the mid-21st century—essentially, a doubling of carbon dioxide concentrations in 300 years.

A vigorous debate is in progress over the extent and seriousness of rising surface temperatures, the effects of past and future warming on human life, and the need for action to reduce future warming and deal with its consequences. This article provides an overview of the scientific background related to the subject of global warming. It considers the causes of rising near-surface air temperatures, the influencing factors, the process of climate research and forecasting, and the possible ecological and social impacts of rising temperatures.

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.

A Guide to Climate Change for Kids

Have you heard your parents or people in videos talking about climate change? Ever wondered what it is and why we care about it so much? NASA scientists have been studying Earth’s climate for more than 40 years. We used what we’ve learned in that time to answer some of your biggest questions below!

Click here to download this guide as a printable PDF!

What is the difference between weather and climate?

The main difference is time. Weather is only temporary. For example, a blizzard can turn into a flood after just a few warm spring days. Climate, on the other hand, is more than just a few warm or cool days. Climate describes the typical weather conditions in an entire region for a very long time – 30 years or more.

What is climate change?

Climate change describes a change in the typical weather for a region — such as high and low temperatures and amount of rainfall — over a long period of time. Scientists have observed that, overall, Earth is warming. In fact, many of the warmest years on record have happened in the past 20 years. This rise in global temperature is sometimes called global warming.

How do we know Earth’s climate is getting warmer?

Scientists have been observing Earth for a long time. They use NASA satellites and other instruments to collect many types of information about Earth's land, atmosphere, ocean, and ice. This information tells us that Earth's climate is getting warmer.

Click here to learn more about how we know the climate is changing!

Why is Earth warming?

Some of the gases in Earth’s atmosphere trap heat from the Sun—like the glass roof and walls of a greenhouse. These greenhouse gases keep Earth warm enough to live on. But human activities, such as the destruction of forests and burning fossil fuels, create extra greenhouse gases. This traps even more of the Sun’s heat, leading to a warmer Earth.

What does carbon have to do with it?

Carbon is in all living things on Earth. As plants and animals die, they get buried in the ground. After enough years, these squished underground remains can turn into fossil fuels, such as coal and oil. When we burn those fuels, the carbon that was in the ground goes into the air as a gas called carbon dioxide, or CO2. Plants and trees can absorb some of this extra carbon dioxide. But a lot of it stays in the atmosphere as a greenhouse gas that warms up the planet.

Has the climate ever changed before?

Yes, but this time is different. Over millions of years, Earth's climate has warmed up and cooled down many times. In the past, Earth often warmed up when the Sun was very active. But nowadays, we can carefully measure the Sun’s activity. We know Earth is warming now, even when the Sun is less active. Today, the planet is warming much faster than it has over human history.

It doesn’t feel hotter where I live. Why does climate change matter?

The average air temperatures near Earth's surface have gone up about 2 degrees Fahrenheit in the last century. A couple of degrees over a hundred years may not seem like much. However, this change can have big impacts on the health of Earth's plants and animals.

What does climate change do to the ocean?

As Earth warms, NASA has observed that sea levels are rising. This is partly due to melting ice. Glaciers and ice sheets are large masses of ice that sit on the land. As our planet warms, this ice melts and flows into the oceans. More water in the oceans makes sea level higher. Also, water expands as it gets warmer. So, warm water takes up more room in our oceans – making sea levels higher.

The properties of ocean water are also changing. One change is called ocean acidification and it can be harmful for plants and animals. Scientists have observed that the ocean is becoming more acidic as its water absorbs carbon dioxide from the atmosphere.

Click here to learn more about how we measure sea level!

How are scientists studying climate change?

Scientists study Earth’s climate using lots of tools on the ground, in the air, and in space. For example, NASA satellites are orbiting Earth all the time. They measure carbon dioxide in the atmosphere. They monitor melting ice and measure rising seas and many other things, too. This information helps scientists learn more about Earth’s changing climate.

What can I do?

Climate change seems big, but it’s something that we can learn about and work on together! NASA’s scientists are studying and monitoring climate change—and there are a few ways you can help them learn more.

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.

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.

Earth > Ask a Scientist About Our Environment > How can kids help prevent global warming?

What are the most important things kids can do to prevent global warming? —  Armano B., Grade 6

Geologist Ed Mathez answers this question:

Dear Armano,

Thank you for your question. It's a really good one. There is no single solution, so let me give you three things that kids can do to help minimize global warming.

1. Conserve energy in your everyday life.

Making simple choices to save energy  may help avoid the serious consequences of global warming. For example:

• Turn off the lights.
• Close doors immediately so heat does not escape.
• Take short showers.
• Walk or bike if you can (instead of having your parents drive you).
• Turn off your computer when not in use (don't leave it on just to keep Facebook or Myspace active).

We can make simple choices to save energy.

2. Convince the people around you to save energy.

Now, you have to be careful here because people don't like to be told what to do, so convince is the important part. Your parents would be perfect subjects for persuasion, but do it with love and humor. Here are some suggestions that you can provide for your family and friends.

• Replace incandescent with fluorescent lights. (This saves a lot of money!)
• Ask your parents not to leave the car running needlessly, for example, when waiting to pick you up at school.
• Recycle  (this saves energy in manufacturing).
• Run the dishwasher and other appliances on energy saver mode.
• Keep the house at 68°F or less. And make sure the heat goes off at night and when everyone is away.
• Start a conservation club at school to raise awareness. Get your fellow students and teachers on board to have the school reduce energy consumption.

It takes energy to produce everything we buy. We can save energy by recycling.

In fact, not knowing is one of the problems. Global warming is a significant risk to society. On the one hand, we do not know exactly what will happen. On the other, we realize that what could happen could be serious. And these consequences could affect different parts of the world in different ways.

3. Keep learning.

These ideas all involve conservation. While that's important, what's more important is finding and implementing sources of energy that do not pollute the environment. Who is going to do that? It can be you! So the third and most important thing you can do is get the best education you can get, so that you can be a responsible citizen and continue making good decisions. Maybe you will help find scientific, technological, economic, or political solutions to the present situation.

You Can Make a Difference!

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.

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

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

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

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

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

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

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

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

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

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

Due to climate change, rapid warming and its further intensification over different parts of the globe have been recently reported. This has a direct impact on human health, agriculture, water availability, power generation, various ecosystems, and socioeconomic conditions of the exposed population. The current study thus investigates the frequency and duration of heatwaves, human discomfort, and exposure of the human population to these extremes using the high-resolution regional climate model experiments under two Representative Concentration Pathways (RCP2.6, RCP8.5) over India. We find that more than 90% of India will be exposed to uncomfortable warm nights by the end of the 21st century with the highest rise over western India, Madhya Pradesh (MP), Uttar Pradesh (UP), Punjab, and the Haryana region. States like Odisha, Chhattisgarh, eastern parts of MP and UP, and some parts of J&K will be the worst hit by the intense and frequent heatwaves and human discomfort followed by the densely populated Indo-Gangetic plains under RCP8.5. Strict enforcement of the stringent policies on stabilization of population growth, improvement of local adaptive capacities, and economic status of the vulnerable population along with enforcing effective measures to curb greenhouse gas emissions are important to reduce human exposure to future heat stress. We demonstrate that a proper mitigation-based development (RCP2.6) instead of a business-as-usual scenario (RCP8.5) may help to reduce 50–200 heatwave days, 3–10 heatwave spells, and 10–35% warm nights over the Indian region. Consequently, this can avoid the exposure of 135–143 million population to severe discomfort due to extreme heat conditions by the end of the 21st century.
