The earth's carbon and water cycles add greenhouse gases naturally to the atmosphere ( carbon dioxide and water vapor largely). These are helpful for the greenhouse effect as they keep the earth warm enough for life Other greenhouse gases like methane come from decomposing organic matter, melting tundra and lakes and from animal husbandry, mostly cattle and pigs More serious greenhouse gases come from man's activities in the last 260 years. We discovered and began burning serious stocks of fossil fuels (coal, oil and natural gas).
This is releasing carbon dioxide that has been sequestered away underground for millions of years Deforestation : We also cut down great swathes of natural forests, that used to absorb carbon dioxide from the air, release the oxygen and store the carbon.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
