Global Warming and Climate Change Essay – For Students and Children In English

Last Updated on

The term Global Warming is used to refer to a rise in the earth’s average surface temperature. This rise in temperature is due to human activities like the burning of fossil fuel, industrialization, etc, which releases gases like carbon dioxide CO2, Methane CH4, and Nitrous Oxide N2O, which are also called greenhouse gases. More than the prescribed concentration of greenhouse gases in the atmosphere traps the heat from the Sun, preventing it to escape the earth’s surface, ultimately causing a temperature rise.

Essay on Global Warming and Climate Change

Essay 1 (250 words)

Climatic changes have become more prominent now because of global warming which is a global concern. Both are hot issues of the current time and it is time to analyze causes and prevention methods to prevent global warming. The release of various greenhouse gases in the atmosphere by many natural means and human activities causes an increase in atmospheric temperature because such gases have the capability to absorb all the heat of the environment from the sun, burning coal, etc. Such gases never let sun rays to go back to the atmosphere however trap heat from them.

An increase in atmospheric temperature causes many climate changes like an increase in sea level, flood, drought, weather changes, increase summer season, decrease winter season, melting glaciers, increase death rate, increase the number of diseases, the declining ozone layer, and other so many climate changes. Fossil fuels burning release more carbon dioxide which is increasing day by day because of deforestation. Plants are the main source to utilize carbon dioxide as food however we are disturbing the natural cycle by cutting more plants.

Burning coal, oil and natural gases are the main cause of global warming. CO2 gas acts as a blanket that retains environmental heat and warms the earth’s surface. The level of carbon dioxide has become increased to a great level in the last century. The earth’s surface has become successively warmer than ever in the last three decades. Each month is becoming warmer than ever which we can feel very clearly. This increasing heat affecting the lives of human beings, plants and animals even many species have been endangered.

There are many reasons behind climate change, some are natural and some are human activities. Climate change is not area or region-specific, it s changing all through the world. Climate change occurs when atmospheric temperatures increase a lot which in turn causes many different changes to the earth such as more floods, intense rain, droughts, increase in the rate of more frequent and severe heat waves, increase level of oceans, melting glaciers, warming oceans, seawater becoming more acidic, and so many. All these changes may become more frequent in the future decades and hugely challenge the society and environment.

In the few past centuries, human activities have increased the release of large amounts of carbon dioxide including other greenhouse gases in the atmosphere. Most of the greenhouse gases come from burning fossil fuels which work as a blanket around the earth and trap all the energy and heat available in the atmosphere and thus warm the earth’s surface. This effect is called the greenhouse effect which triggers climate to change to a huge level and result in dangerous effects on the lives and ecosystems.

Such a warmer climate affects the availability of natural water supplies, crop production, agriculture, natural environment, safety, security, etc. Such huge climate changes are unavoidable however cannot be stopped at once.

Global warming has really affected and forced the climate to change over the last century throughout the world. An unusual increase in the earth’s average temperature is because of the high amount of greenhouse gases released due to burning fossil fuels and other human activities. Some of the greenhouse gases having more influence on the climate are CO2, water vapor, dinitrogen-oxide, and methane.

According to the research, it has been recorded that almost 30 percent of the heat by incoming sunlight gets reflected back to space through clouds and ice but because of global warming ice is melting. It means there are no left sources to send heat back to space and all are getting collected in the earth’s atmosphere and affecting the climate.

A huge level of climate change in the current time attracts people’s attention very easily. Every one of us is feeling very clearly from the short-term changes in the seasonal patterns of temperature, drought, rainfall without season, changing weather patterns, etc to the long-term changes affecting the entire earth. Climate is a long-term weather trend affecting human lives positively or negatively.

Climate change is the long term variations in weather patterns. Climate itself adjusts from time to time however going on the wrong path for many years because of regular loss of huge ice sheets. Earlier the earth atmosphere was covered with ice sheets that were able to make the earth atmosphere cool by preventing the earth from heat and sending back extra heat out of the space from the earth.

Climate has changed from cooler to warmer over the last two million years in a cyclical manner. Sun is the ultimate source of heat energy which fueling the weather systems after reaching to the earth. Earlier the harsh and extended bitter cold season was called the little ice age which was due to the huge level variations in the solar activity. It is found that positive human activities may play major roles in shaping the earth’s climate.

Such huge variations in the climate may lead to the danger of human lives. Earlier it was believed that shifts in the climate pattern from the ice age to warmer periods were because of time however later it was imagined that it is due to regular melting of ice sheets of more than a kilometer in thickness. Our climate is getting warm rapidly by the rate of approximately 8°C over the course of 10 years.

A huge industrial revolution in modern times has largely impacted the global climate system by increasing the number of greenhouse gases in the earth’s atmosphere. The heat-trapping nature of greenhouse gases contributes to global warming. According to the Intergovernmental Panel on Climate Change (IPCC), the increase in earth’s average surface temperature by the 20th century has been approximately 0.6°C.

It has also been recorded in the northern hemisphere over the last century that there is a decrease in snow cover by 10 percent, decrease in spring and summer sea-ice by 10-15 percent, increases in rainfall and its intensity, huge level change in shifts of ice freezes and breaks up in the rivers and lakes.

Global warming refers to an increase in the earth’s average temperature. Climate change, on the other hand, is one of the most significant consequences of global warming. Though global warming and climate change are often used interchangeably, they are distinctly different from one another. In the following essay, we will study global warming and climate change in detail.

What is Global Warming?

Global warming refers to the long term warming of the planet since the industrial revolution in the 1970s. Since then, the average temperature of earth has gone up by a little over 1°C, a change that might seem small, but even small changes in the earth’s temperature could have damaging effects and moreover the temperature is still gradually on the rise.

What is Climate Change?

Climate change is an implication of global warming. Global warming results in unexpected weather changes, apart from other effects like melting glaciers, raised ocean temperatures, and extreme cold or heat. These conditions all together cause changes in climatic conditions throughout the globe.

What Causes Global Warming?

One of the main causes of global warming is an escalated greenhouse effect. It is an effect caused by the increased atmospheric condition of Greenhouse gases like Carbon dioxide (CO2), carbon monoxide (CO) and Methane (CH4). These gases are emitted as byproducts of fossil fuel production and use. Humans extensively use fossil fuels resulting in the increased atmospheric concentration of greenhouse gases, consequently resulting in a greenhouse effect.

In order to understand global warming, let’s understand the greenhouse effect. Under ideal conditions, the earth’s atmosphere contains a number of gases including quantities of greenhouse gases. During sunlight hours, these gases do the job of filtering UV rays of the sun and also the intensity of the sun’s rays. In the night these gases help retain the heat absorbed by the earth during the day, by not letting it escape in the atmosphere, thereby resulting in a maintained temperature of the earth.

What Causes Climate Change?

Greenhouse effect as explained above is primarily responsible for climate change. Sun’s heat is blocked from escaping the surface of the earth by certain gases that form a thermal blanket over the earth. These gases constitute primarily of water vapor (H2O) and other gases like carbon dioxide (CO2), Methane (CH4) and Nitrous oxide (N2O), and are responsible for maintaining earth’s temperature to a life-supporting 15°C.

These gases are called greenhouse gases. The problem arises when the atmospheric concentration of greenhouse gases rise above the permissible level. Human activities like industrialization and excessive use of fossil fuel produce greenhouse gases.


Climate change is a consequence of global warming, and the latter on the other hand is caused by human activities. The greenhouse effect has been responsible for maintaining the earth’s average temperature to a livable 15°C, but in recent decades, there has been an escalation in the greenhouse effect, due to an increase in human-produced greenhouse gases.

With the rise of the greenhouse effect, abrupt climatic changes across the globe become inevitable, often resulting in extreme events like famine, droughts, floods, and cyclones. Global warming and climate change both are directly linked to human activities and only humans have to power to reverse or at least nullify the effects.
