Humans Cause Global Warming?

It seems that each day we hear of another scientist that distances themselves from the whole "humans cause global warming" theory. Here seems to be a good site to get the other side of the story, by a scientist.

My take on the whole thing, is this is a natural occurrence (the Sun naturally going through it's cycles, seems to be the best explanation), and just like a tornado, or hurricane, there is nothing we can do about it. The Dems and other Libs have jumped on this and made it their "pet" project to thwart 3rd world countries from developing. Once the GOP and other Cons saw this logic, of course they jumped on the bandwagon.
