Well, we know he created his Youtube account two months ago (as of this writing). He's uploaded only one video, also two months ago. He's also better known as DCI, a Republican PR firm that has Exxon as a client, amongst others. Exxon claims to know nothing about the video and DCI says that "[they] do not disclose the names of [their] clients, nor do [they] discuss the work [they] do on behalf of [their] clients."
Nice to know the Republicans are still fighting this issue when even George Bush admits that humans are partially responsible for global warming. Of course, he also made it clear he would refuse to accept any attempts to impose limits on carbon emissions. Isn't that kind of like admitting that Russian Roulette is stupid but refusing the pull the gun from your head?
George Bush isn't that stupid, though. He knows Russian Roulette is stupid, but he's holding the gun to the collective heads of our children. Thanks George!
(Update: fixed the first link to point to the video it's supposed to point to.)
