This is a very fascinating debate, and I highly recommend you watch the whole thing. This may be the most thorough review of skeptic concerns I have ever seen, and I came away from it with enough sources of science to reach my own conclusion. The Debate follows an interview with Martin Durken, who made a documentary called The Global Warming Swindle. I’ll warn you, the Q & A section after the debate gets really bizarre. I’m not kidding, it’s messed up in pt.8.
Debating Panelists: Professor Bob Carter (Geologist, Skeptic). Professor David Karoly (IPCC Climate Scientist), Ray Evans (Lavoisier Group Skeptic), Nick Rowley (UK Climate Change Strategist), Dr Nikki Williams (CEO, NSW Minerals Council), Robyn Williams (science journalist and broadcaster)
