First, I havent sat through the entire "Inconvenient truth" as I thought it got a little boring and had heard all of the data before in some of my classes. Second, its not just carbon I'm taking about, which is why I stated 'ppM of particles' - we put a ton of nasty shit into the air thats not naturally there, and it would be hard to believe that that doesnt effect our climate. Your graph is only carbon, whoopee.
Also, even if Gore logged his graphs as I've heard his critics cite, you still cannot deny that the oceans have been absorbing an absolute shit-ton of energy in the last few decades. As I'm sure you know, a tenth-of degree average rise in temps across the globe equates to an incredible amount of heat energy.
To be honest, I really hate how this has turned into a politically charged argument. It shouldn't be. Gore's as guilty as some of the right-wing nutcases on the other side of the fence, but this shit just sickens me above everything else involved in this topic.
