The National Review has done a long and in-depth article on Michael Mann and freedom of speech entitled The Climate Inquisitor.
Secure as he appears to be in his convictions, Mann has nonetheless taken it upon himself to try to suppress debate and to silence some of the “irrational” and “virulent” critics, who he claims have nothing of substance to say. To this end, Mann has filed a lawsuit against National Review. Our offense? Daring to publish commentary critical of his hockey-stick graph and disapproving of his hectoring mien.
The Hockey Stick Illusion gets a mention too.
