Global warming is happening today because we humans are destroying our land. The cause of Global warming is by us humans for we have been throwing our trash onto the land and burning it. The trash that we throw onto our land contains methane gas and when we burn the trash the methane gas rises and it affects our atmosphere. Our atmosphere is a thin layer of different kind of gases and it helps our earth by weakening the suns heat rays before entering into the earth. Also it makes the heat go back out, but with all the trash burning we've been doing the atmosphere is getting weaker and the suns rays are getting stronger because the atmosphere is weak. Not only does it not weaken the suns rays it doesn't let the heat go out as easily as it used to. And that is what is one thing that is causing Global warming.
