Studies done to prove Global Warming? For a biology project that im doing I need to find a study that proves global warming is happening or anything of that sort. Does anyone know were I can find this sort of study? Thanks!

This graph suggests that CO2 is responsible for the current warming.

Edit: Global warming isn%26#039;t a proven theory, there is only guesses.

Watch this, then you may need to change your report slightly.
