SCIENTIFIC DOCUMENTARY: The Great Global Warming Swindle
On: Channel 4 (104)

Date: Thursday 8th March 2007 - 21:00 to 22:35

Polemical film challenging the consensus that man-made CO2 is heating up
the earth. Featuring leading academics, the film questions the science
behind the accepted reasons for global warming and argues other
explanations for climate change are not being properly aired.
