Global warming is real. Hell, I even heard Bush stutter it through his second grade speaking ability, so it has to be true. I find it kind of contradicting though, considering the fact that the Bush administration didn't even enforce the Clean Air Act at most times.

Also, it was reported by the Union of Concerned Scientists that ExxonMobil has spent $16 million in funding of specialized groups to create confusion on global warming. Through these groups, ExxonMobil can spread false information about global warming (perhaps like the "Unstoppable Solar Cycles" DVD).
