Oh my goodness, I had no idea that "Over 400 Prominent Scientists Disputed Man-Made Global Warming Claims in 2007".

So I put it in Technorati. There I found many excited climate change-denying blogs. But I also found this from desmogblog: 400 Prominent Scientists Dispute Global Warming - Bunk

It's a good post with some good comments. You pretty soon realise that the authors of the report have some very, er, liberal views of what a "prominent scientist is" (eg it appears to include a British Viscount with a degree in Classics who originally advocated quaranting all carriers of HIV). Plus the usual trick of quoting out of context.

Thank goodness for the internet.
