Global Warming A Hoax?

It's no secret to those who know me that I believe global warming is occurring. The big issue is obviously weather or not we're causing it. I've watched Al Gore's "An Inconvenient Truth" and a lot of what he says seems to be accurate and logical. The one thing he does purport that's a little sketchy is that the correlation between CO2 levels and temperature means that one is caused by the other. This Google Video I found seems to offer a very valid argument against his claims.
