I see it like this: I am a scientist by training. And though I am a physicist (with a PhD in Computational Materials Engineering), not a climatologist, I do know how the whole scientific process works.
And on one side I see the vast majority of all peer-reviewed climatological research and publications... and on the other I see lies, distortions, and statistical tricks more often than not. At one point I set to examine the claims of one especially prominent global warming denier - one Christopher Monckton, who often shows up on TV on such matters. Here is what I found:http://jhubert.livejournal.com/181274.html
From what I have seen, this is not an isolated incident - tricks like these are systematic on the denier side. Thus, I have come to the conclusion that this is not a debate about science, but an effort to sway public opinion. The real
scientific debate about global warming is how drastic it will be, and how it affects different regions - not whether it happens at all, or whether humans are the cause.
