There is a very interesting article at Philly.com, featuring Michael Mann and Doug Nychka among others. Nychka is a statistician who is closely connected with the Hockey Team and was a member of the NAS panel that investigated the Hockey Stick.
Choice quote:
Nychka, who works for the National Center for Atmospheric Research in Boulder, Colo., said the [Hockey Stick] became so controversial because it was misinterpreted as proof that humans cause global warming.
This misinterpretation was of course due to, among others, IPCC WG1 head, Sir John Houghton.
