This is odd. The Hockey Stick Illusion no longer appears in the Amazon Global Warming category. Looking more closely, this seems to be a problem with many sceptic titles, particularly the newer ones: Booker, Bob Carter, Roy Spencer, and Christian Gerondeau. Older sceptic titles, by the likes of Plimer, Lawson, Peter Taylor and Lomborg are still there.
Very odd indeed.
I wonder if something along these lines has happened?
