Did Joe Biden just say Global Warming was man made is he crazy im all for Obama but this is crazy ?

He's crazy. If Biden and Gore want to ignore the 30,000+ signatures (and yes, these are credible people) of the Global Warming Petition Project, fine. That tells me the global warming scare by the left is clearly a political maneuver and not the threat they make it out to be. Gore, fraud that he is, refuses to debate the issue one on one. His presentation of nonsensical climate data was a sham and he should be forced to forfeit the Nobel Prize.
