Michael Mann, now feigning sensitivity towards Mark Steyn’s use of the word “fraudulent”, used identical language in the Climategate emails against critics without the slightest compunction. Mann’s hypocrisy has been widely noted.
Unpublicized thus far is a discussion by EPA, in which EPA concluded that Mann’s accusations of “scientific fraud” were within the scope of “acceptable and appropriate” scientific exchange and that it is “entirely acceptable and appropriate for scientists to express their opinions and challenge papers that they believe are scientifically flawed” in such terms.
The EPA’s finding appears to be inconsistent with Gavin Schmidt’s recent tweet arguing that such language is “per se defamatory”:
Saying that ppl [people] are frauds is per se defamatory. Goes beyond disagreement/error/dislike.
