That's a cute meme of false positions you've got there..I think I saw it over on the Warmite Talking Points Page.
The fact is quite simply that the theory of AGW is unproven. There seems to be some warming going on, true, but it's consistent with previous periods when the planet was coming out of an Ice Age. Historically the planet is cooler than it's been for large chunks of its timeline. The warming tracked in the last 40 years or so is more likely traced to natural causes and our cleaning up of the atmosphere (not as much haze/brown clouds/etc.), which lets a bit more light through.
AGW is intriguing and has a lot to admire--and it's fundamentally nearly impossible to prove. Drawing graphs that show temperature increases mapped against mankind CO2 output is nice exercise but that's an attempt at correlation, not causation. One could just as easily draw a graph that maps increases in temperatures against MPG increases in cars to the same result. And it's absolutely immaterial that there's any kind of "consensus" of any number of people--facts ARE or ARE NOT, belief in them has no bearing on the subject. There used to be widespread European consensus that the world was flat--that didn't make it so.
Maybe we should gather data before we start ripping apart our economy over an unproven theory.
