Global warming counter claims

I was listening to the radio this afternoon as I drove back to work from lunch and there was an interesting topic being discussed. Apparently, a group of well respected international scientists have been banned from attending the climate change conference in Bali because they represent a dissenting voice in the global warming debate. When I got back to work, I looked into this group and they seem to be legit. The interesting thing I found was this video [below] discussing some of the falicies of the 'science' used in An Inconvenient Truth. We've had these sorts of discussions here before, but this is the first time I have seen anything in this form disputing the 'evidence' given by the former Vice President.
