Global warming has become a fierce debate pitting a majority of people and scientists against an ever growing minority convinced it is not due to man.  In this Hardball piece Chris Matthews asks former House Majority Leader Tom Delay about what he believes about global warming.  The Believability Meter puts Tom down as one of the minority who steadfastly believe that climate change is not due to man nor is there any science to prove otherwise.  However, there is a little blip at 24 seconds when he tries to say that the economy is being undermined and people's freedom taken away if you believe in global warming.
