Andy Russell, a climatologist from Manchester, has written a brief history of the Hockey Stick. He says he hasn't read the Hockey Stick Illusion, which is a pity because he hasn't really moved things forward at all. There are many things he gets wrong that are covered in the book.
I've suggested he gets hold of a copy.
(Andy's piece is not inflamatory and I hope anyone commenting there will reply in the same vein).
