What is a formal essay on global warming?

Answer 1

Global Warming is an increase in the average temperature of the earth's atmosphere, especially a sustained increase sufficient to cause climatic change.

Humans are to blame for global warming. They have contributed in many different ways such as burning fossil fuels like natural gas, coal and oil making CO2. Deforestation; taking trees and cutting them down. Also population growth is affecting it too.

Burning natural gas, coal and oil is producing masses of non-used CO2. This is resulting in the melting of the arctic ice and leaving polar bears and other arctic animals without a home. For example the glacier national park, in Montana, now has only 27 glaciers, compared with 150 in 1910 that is not very many. Carbon dioxide (CO2) heats the air and the water causing the earth to heat up and resulting in melting the arctic ice. Some scientists believe that the ocean warming is resulting in increased CO2 and not the other way around. This theory is based on the idea that there is CO2 trapped in the ocean and as the temperature rises and the water evaporates the CO2 is released therefore causing the melting of the icebergs.

Deforestation is affecting global warming because trees breathe out O2 (oxygen) and breath in CO2 (carbon dioxide). So if there is a shortage of trees that are not going to breathe in our CO2 then were stuck with more carbon dioxide in our atmosphere resulting in the air warming up because of the overload of CO2. Leading scientists think that we are contributing to global warming by deforesting areas of our earth which is not only killing innocent animals but can and probably will kill us if we keep polluting.

Population growth is also affecting global warming in a bad way. More people means more cars, more cars means more fossil fuels burnt, more fossil fuels burnt means more pollution which pollution contains many greenhouse gases such as hydro fluorocarbons (HFCs ), per fluorocarbons (PFCs )and sulphur hexafluoride (SF6) which are results exclusively from human industrial processes. Leading scientists believe that we are contributing to global warming in a big percentage by reproducing

To sum up we are causing global warming in a bad way by burning natural gas, coal and oil concluding in heating up the water and melting the icebergs. Deforestation means less oxygen and more carbon dioxide. While population growth is affecting it by manufacturing more cars and factories. Leading scientists believe that we are the cause of global warming.
