While last week the best minds in climate science were gathering in Copenhagen, the previous week the finest minds in climate scepticism gathered in New York for the 2008 Heartland Institute International Conference on Climate Change.

Heartland is a conservative US thinktank with extensive ties to tobacco companies. This year’s conference was its second effort on climate change, and attracted representatives from smaller conservative and free enterprise groups around the world, but few of the higher-profile sceptics like David Bellamy that attended its first effort. Many of the attendees came from bodies funded by fossil-fuel companies, although Heartland itself refuses to reveal its funding sources.
