Essay On Global Warming and Climate Change In English When the average surface temperature of the earth rises, it is referred to as global warming. Human activities like the combustion of fossil fuels, industrialization, etc., which produce gases like carbon dioxide CO2, methane CH4, and nitrous oxide N2O, commonly known as green house gases, are to blame for this temperature increase. Overly concentrated levels of greenhouse gases in the atmosphere trap solar heat, preventing it from escaping to the earth’s surface and, ultimately, raising global temperatures. The Greenhouse Effect is the name of this effect. This shift in the earth’s temperature has an unanticipated impact on the weather. Numerous places face intense downpours, droughts, and a change in the monsoon.

Essay On Global Warming and Climate Change In English (100 Words)
Because of increased global warming brought on by both natural and human causes, the entire world’s climate is changing on a regular basis. The ecosystems and people’s lives are both significantly impacted by all the changes. Over the past 30 years, the average global temperature has risen by 1 degree.
According to the Intergovernmental Panel on Climate Change (IPCC), by 2100, the average global temperature may rise by 2 to 8.6 degrees Fahrenheit. Increased emissions of heat-trapping gases known as “green house gases” into the atmosphere are to blame for the rate at which the earth’s temperature is rising.
Essay On Global Warming and Climate Change In English (200 Words)
Although there are many causes of climate change, including earth’s natural cycles, global warming is the main culprit. The world’s numerous human activities and technical advancements are causing greenhouse gases to rise and accumulate in the atmosphere, which in turn causes the temperature of the environment to rise quickly and easily, making the globe around us hot and heated. Other effects of climate change include rising sea levels, which lead to floods that breed malaria and other parasites, increased coastal erosion, the destruction of dwellings in coastal states, and many more.
The existence of life on this planet is hampered by higher temperatures, and numerous significant plant and animal species are in danger of extinction. More heat-related injuries are caused by prolonged and intense heat waves, while water evaporation from smaller bodies of water is accelerated by greater air temperatures.
In different locales, the ever-rising temperature has diverse consequences, such as raising some water levels and lowering others. Freshwater, an essential resource for life on this planet, is becoming less and less available everywhere. Some crops are exceedingly difficult to cultivate in such a hot climate; for example, if the temperature climbs by 3.6 degrees Fahrenheit, corn productivity may be reduced by 10 to 30%.
Essay On Global Warming and Climate Change In English (300 Words)
There are various causes for climate change, some of which are human-made and others of which are natural. Global climate change affects every country and location in the world. When atmospheric temperatures rise significantly, climate change results. As a result, the earth experiences many different changes, including more floods, heavy rain, droughts, frequent and severe heat waves, rising ocean levels, melting glaciers, warming oceans, more acidic sea water, and a host of other things. In the coming decades, all of these shifts could occur more frequently and pose a serious threat to society and the environment.
Human activities have boosted the atmospheric release of vast volumes of carbon dioxide and other greenhouse gases over the last few millennia. The majority of greenhouse gases are produced by burning fossil fuels, which act as a blanket over the planet, trapping all the energy and heat present in the atmosphere and warming the surface of the planet. This phenomenon, known as the greenhouse effect, causes the climate to change dramatically, endangering human life and ecosystems in the process.
The availability of natural water sources, crop productivity, agriculture, the environment, safety, and security, among other things, are all impacted by the warmer climate. Although these significant climate changes cannot be halted immediately, they are inevitable.
Around the past century, global warming has had a significant impact on and driven changes in climate all over the planet. The enormous amount of greenhouse gases released as a result of burning fossil fuels and other human activities is what’s causing the unusual rise in the earth’s average temperature. CO2, water vapour, dinitrogen oxide, and methane are a few of the greenhouse gases that have the greatest impact on the climate.
Nearly 30 percent of the heat from incoming sunlight is noted in the research to be reflected back to space through clouds and ice, but ice is melting due to global warming. It implies that there are no longer any sources of heat that can be used to return heat to space; instead, all of that heat is being gathered in the earth’s atmosphere and influencing the climate.

A significant level of climate change today quickly draws people’s attention. Every single one of us is quite aware of everything, from the short-term changes in the seasonal patterns of temperature, drought, and rainfall to the long-term changes impacting the entire planet. A long-term weather trend called a “climate” can have a beneficial or bad impact on people’s lives.
Long-term changes in weather patterns are known as climate change. The climate itself changes from time to time, but has been trending in the wrong direction for a long time due to the recurring loss of large ice sheets. When ice sheets blanketed the world’s atmosphere in the past, they were able to keep the earth’s atmosphere cool by shielding it from heat and reflecting back excess heat into space from the earth.
Over the past two million years, the climate has cycled from being cooler to warmer. The ultimate source of thermal energy that powers the earth’s weather systems is the sun. In the past, the severe and protracted period of bitter cold was referred to as the “little ice age” because of the enormous changes in solar activity levels. It has been discovered that beneficial human activities may have a significant impact on the planet’s climate.
A climate with such extreme changes could endanger human lives. Earlier, it was thought that changes in the climate from ice ages to warmer times were caused by the passage of time; but, more recently, it has been hypothesised that these changes are caused by the frequent melting of ice sheets with a thickness of more than a kilometre. Over the course of ten years, our climate will increase by about 8°C at a rapid rate.
By increasing the amount of greenhouse gases in the earth’s atmosphere, the massive industrial revolution of the modern era significantly altered the world climate system. The heat-trapping properties of greenhouse gases cause global warming. According to the Intergovernmental Panel on Climate Change (IPCC), the average surface temperature of the globe increased by about 0.6°C by the 20th century.
Additionally, over the past century, it has been observed in the northern hemisphere that there has been a 10% decrease in snow cover, a 10-15% decrease in spring and summer sea ice, an increase in rainfall and its intensity, and a significant shift in the amount of ice that freezes and breaks up in rivers and lakes.
Essay On Global Warming and Climate Change In English (500 Words)
The term “global warming” describes an increase in the planet’s mean temperature. On the other hand, one of the most important effects of global warming is climate change. Despite the fact that the terms global warming and climate change are frequently used interchangeably, they are not the same thing. The next essay will go into great length on both global warming and climate change.
How does global warming work?
The term “global warming” describes the planet’s long-term warming since the industrial revolution in the 1970s. Even seemingly insignificant increases in the earth’s temperature can have negative effects, and the temperature is still slowly rising. Since that time, it has increased by a little over 1°C on average.
How does the climate change?
Global warming has an effect on climate change. In addition to typical consequences like melting glaciers, elevated ocean temperatures, and extreme cold or heat, global warming causes unexpected weather shifts. Global climatic changes are brought on by these factors taken together.
Why does the world get warmer?
An intensified greenhouse effect is one of the primary drivers of global warming. It is a result of an increase in greenhouse gases including carbon dioxide (CO2), carbon monoxide (CO), and methane in the atmosphere (CH4). Byproducts of the production and usage of fossil fuels include these gases. Fossil fuels are heavily used by humans, which increases the quantity of greenhouse gases in the atmosphere and, ultimately, causes the green house effect.
Let’s first comprehend the green house effect in order to comprehend global warming. The earth’s atmosphere contains a variety of gases, including significant levels of greenhouse gases, under ideal circumstances. These gases work to filter the UV rays and the intensity of the sun’s rays while it is daylight. Because they prevent heat from escaping into the atmosphere throughout the night, these gases contribute to the maintenance of the earth’s temperature.
A bigger green house effect occurs from human activities like industrialisation and widespread use of fossil fuels, which produce greenhouse gases (such CO2, CH4, CO, etc.). Imagine yourself inside a car on a sunny day with all the windows drawn up to help you grasp the green house effect. The sun’s rays will enter the automobile through the glass, but because it is entirely closed, they cannot leave and return to the outside air, increasing the temperature inside the car. Global warming is caused by a process known as the “green house effect.”
How Does Climate Change Happen?
The above-described “green house effect” is mostly to blame for climate change. Certain gases that form a thermal blanket over the planet prevent heat from the sun from escaping the surface. These gases keep the earth’s temperature at a life-supporting 15°C and are mostly made up of water vapour (H2O) and other gases like carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).
They are referred to as greenhouse gases. When the atmospheric concentration of greenhouse gases exceeds the allowable limit, a problem occurs. Greenhouse gases are produced by human activities like industrialization and excessive fossil fuel use.
The increased green house gas concentration in the atmosphere causes a stronger green house effect, which elevates the earth’s average temperature above 15°C.
