[Colonel Flagg]

Anyone who claims that global warming is "solely caused by" anything is either delusional, horribly misinformed, or pushing an agenda with no other tool but a loud voice and disdain for anyone who disagrees with their worldview. (Sound like anyone we know?)

The climate is insanely complex, and is only now beginning to be accurately modeled by computers, chiefly because of the insane rate of increasing computing power. Mankind's activities no doubt have an effect - the magnitude of that effect is what is disputed. The sun is the prime engine of the Earth's climate, so there's also no doubt that fluctuations in the solar output will have an effect on climate. And then there is volcanic activity, which has also been extremely high of late. Finally, it's not just about the amount of emissions, it's where they end up in the atmosphere.

More to the point, Mr. Van Houten, I think you have a viable premise, as long as you make a more than gratuitous nod toward the other potential causes (to first order). Keep it focused on the facts, and try like hell to keep politics out of it.
