Real Science did a post where he asked for your conversion moment to being a skeptic, if you had one: http://stevengoddard.wordpress.com/2012/07/18/2006-my-year-of-enlightenment/#comment-101862. My comment:
Here is the video — the three and half minutes of video — that converted me into a skeptic (disbeliever actually). In ~ June of 2007, by a chance click of a link, I watched the hour long Great Global Warming Swindle. But it was just the short “Al Gore segment” on CO2 that really really got my attention. I watched in astonishment as I realized, then and there, if this was true, that I had been had by the warmists. After I had done extensive googling looking for an effective rebuttal from the warmists, and found none, I was an anti-warmist. Realize that what this video shows is algor repeating the ipcc’s deception on CO2. This is a deception that pretty much still holds with the public at large, that’s why it’s important to try to share and promote this video:

It was the ice core lag that turned me to skeptic as well...although I had gotten suspicious a bit before that when the Mann hockey stick graph got exposed as using faulty statistics.
