Global warming is the very hot topic now because of being high risk environmental issue. Students are generally assigned to write or say something about the main causes of the global warming. In order to help your children, we have provided some easy paragraphs and simple long and short essay on the causes on global warming.
Essay on Causes of Global Warming
Causes of Global Warming Essay 1 (100 words)
Global warming is the gradual warming of the earth surface because of the continuous increasing in the temperature of the atmosphere due to some natural and human made causes. The main cause of the global warming is the collection of greenhouse gases in the earth atmosphere which work as a blanket and trap lots of heat causing rise in temperature of the atmosphere. CO2 (also called carbon dioxide) gas is not good for the atmosphere, if it remains longer in the atmosphere, it would trap heat extremely which ultimately increase global temperature. High level of CO2 emissions in the atmosphere are caused by the burning of fossil fuels, cars, vehicles, coal-burning power plants, etc.

Global warming is caused by two reasons, one is natural causes and another is human made causes. Human beings are doing deforestation to a great extent however trees are main source to utilize carbon dioxide and perform global carbon cycle to maintain the percentage of this gas in the atmosphere. Deforestation has almost stopped this positive process of the plants of utilizing the CO2 which in turn increases the level of atmospheric carbon dioxide and rise in atmospheric temperature day by day.
Population growth is another main cause of the global warming. Increasing human population on the earth increases the need of living land and destruction of the forests. Increasing demands of the number of vehicles by the human beings cause fossil fuels to burn more which ultimately increases in the level of atmospheric carbon dioxide. The use of fossil fuels by the human beings in the transport vehicles cause carbon emission which gets collected in the atmosphere, trap heat, increase atmospheric temperature and cause global warming. Sulphur group gas (release from the burning of fossil fuels) is also very harmful which contribute around 30 percent rise in the global warming.
Causes of Global Warming Essay 3 (200 words)
Global warming is the ultimate rise in the atmospheric temperature which is caused by the some natural processes or some man-made causes. The most important cause of the global warming is the cutting of the plants and increasing level of burning of fossil fuels. Other reason of global warming is regular climate change cycles which repeat over a period time. From the creation of the earth the cycle of cooling and cycle of warming continues till now. However, global warming is also increasing by the some man-made causes which need us to worry about and start prevention methods.
Methane greenhouse gas is another cause which is released from the animals like cattle. Wetlands and tundra geography also contributes to release of this gas into the atmosphere which in turn traps heat and causes increase in warming of planet. Solar cycles, sunspots and rotation of the earth are also some natural causes of the global warming. In this, planet warms naturally without human efforts and contributions. Because of the sun spots and solar flares, earth temperature increase does warm up some but this is usually temporary, and when the solar cycle cools off so does the earth. However it is temporary and causes cooling in another cycle. Volcanoes are also a natural cause of increasing global warming.

Global warming is causes by the increase in the temperature of the planet gradually. It is gradual process however very dangerous for the whole human fraternity. It is the indication of the end of the life on this planet if the effects of global warming continue. Natural cause of the global warming is the variations in the solar radiation, solar flares or sunspots, etc are directly impacting the global temperature. Earlier in the seventeenth century the average global temperature was around 1 degree Celsius which was much cooler than today.
Some changes in the sun activity charged particles to originate from the exploding stars of galaxy which enters to the atmosphere and ionize with small moisture particles and form water droplets and then clouds. Such clouds causes reflection of sun energy back to the space and become the reason of rise in global temperature. Natural forest fires also cause increase in the atmospheric temperature as vegetation burning releases stored carbon and increase level of green house gasses. Melting permafrost in the North and South Poles at high level also contributes to the global warming. Other natural causes are the changes in solar activity, volcanic eruptions, natural forest fires, etc.
The main causes of the global warming are the human made causes which are deforestation, increasing human population, increasing demand of the vehicles, burning fossil fuels, burning of coal, oil, gas, etc which increases the atmospheric greenhouse effect and ultimately enhance the temperature of the atmosphere.
Causes of Global Warming Essay 5 (300 words)
The main cause of the increasing global warming is human being however some natural causes also contribute to the global warming. The main culprit of global warming is the increase in greenhouse gases in the atmosphere of this planet. Burning fossil fuels and deforestation causes carbon dioxide to store in the atmosphere which traps heat and becomes the reason of earth warming and greenhouse effect causing global warming. The most important contributors of causing greenhouse effect are carbon dioxide gas, water vapour, methane and ozone.
Coal and oil mining releases the methane gas to the atmosphere. Other natural leakage causes additional source of methane release. Human being are cutting down trees and forests to a great level per year which affect the natural carbon cycle and cause carbon dioxide gas to store in the atmosphere. Plants are considered as the main source to utilise all the carbon dioxide gas on the earth. In this way the increasing concentration of carbon dioxide gas causes increase in the greenhouse effect which again warm the atmosphere by increasing temperature.
Release of nitrous oxide from the fertilizers (used for crops) and gases used in the refrigerator including other industrial processes are also the main factors of global warming. Melting ice releases methane as ice has trapped a compound called methane clathrate which released after melting. Also the ice caps and glaciers reflect sunlight back to the space (means preventing earth from high temperature sun rays) and after melting of ice this process stops and causes earth to warm. Burning of wood at high level releases the oxidizable carbon in the earth atmosphere which ultimately elevates earth temperature. An emission of chlorofluorocarbons (used in the freeze) is the major reason of abnormal earth warming. It does not trap heat however it releases chlorine in the presence of UV sun rays which goes to the atmosphere and weakens the ozone layer by changing ozone molecules into the oxygen molecules.

Global warming is a gradual process however increasing day by day because of the human beings. There are many natural causes also but they are contributing less than the human made causes. Now the effects of global warming can be easily felt by us such as decreasing winter season length and increasing summer season length. Earth is getting warm and warmer, even in the last decades the temperature of the earth has increased to a great extent. There are some effective measures following on the global level by the human beings may reduce the effect of global warming. Increasing effect of global warming indicates the end of life existence on the earth. The main reason of the origin of this demon is the human mistakes.
Burning fossil fuel naturally or by man increases the level of carbon dioxide emissions (coal powered plants-93%, power production industries-40%, and other industries) in the atmosphere. Other reason of increasing CO2 emissions is increasing demand of the vehicles on the road. Vehicles use gasoline which causes emission of CO2 gas as a by-product. Some faulty engines of the vehicles or vehicles giving less mileage contribute more carbon emission. Now-a-days, automobile manufacturers have been warned to manufacture more efficient engines of the vehicles in order to reduce carbon dioxide gas emission to the atmosphere. Increasing demands of the vehicles are creating more challenges to the global warming.
Deforestation and increasing human population are the main reasons of the increasing global warming. Deforestation causes removal of plants from the earth which disturbs the natural carbon cycle. Plants are the main utilizers of the carbon dioxide gas as their food and when the number of plants decreases on the earth cause increase in the level of this harmful gas in the earth atmosphere. The released CO2 gets collected in the environment and absorbs more heat from the sun rays and ultimately increases the temperature of the earth. The increased earth temperature cause increase in the global warming.
Animals are also the source of releasing some methane into the atmosphere which is also harmful for the earth. Burning of coal, oil, and gas causes increase in atmospheric greenhouse effect and rise in temperature which causes ice caps to melt and heat the earth. Ice caps play great role in the cooling of the earth by reflecting sun heat back to the space, however cooling effects lasts when ice caps melts.

Global warming is making big changes in our beautiful world. It’s caused much of the ice in global areas to melt away. Many animals are losing their homes and are becoming endangered. When something becomes endangered their numbers are dropping and there are becoming fewer of them. Some of these animals are tigers, elephants, the blue footed booby, and polar bears.
Global warming is caused by rising of the average temperature. Today it is already 1 degree warmer than one hundred years ago! That may not sound like much, but already it is making huge changes in our beautiful Earth.
One place being effected by Global warming is the Arctic. Much of the ice there has melted and temperatures are rising rapidly. What used to be a frozen beauty is now a barren wasteland. Many animals there are adapted to the cold weather. They cannot live anywhere else.
Some things that can be done to stop Global warming are not using things that have carbon dioxide in them. You could also help by taking buses and try carpooling with friends. Riding your bike to school and other public places can also help. Even better, walk on your own two feet. God gave them to us for a reason!
I think it is important to stop Global warming because I want my grandchildren to be able to see a beautiful sparkling Iceland, not a barren wasteland. You may say “it doesn't’t matter, it doesn't’t harm us!” But the thing is, it does harm us! Here are some of those things: 1. Global warming is melting permafrost, soil that is usually frozen. 2. It is making some places too dry. 3. It raises the sea level. 4. It changes the ocean chemistry and harms coral reefs and other sea life. 5. Warming causes stronger hurricanes and tornadoes, and more forest fires, and bigger blizzards. 6. It causes animals and plants to either die or move. 7. Strange weather hurts food crops.
Now that you know what I mean, think about it. We need our beautiful world. God gave us this beautiful place to share in peace and harmony. So we all need to work together to keep it a beautiful place full of wonder and beauty.
