You didn't discuss the fake PSU investigation. Here is what Clive Crook, a liberal writing for Atlantic magazine had to say: "
"The
Penn State inquiry exonerating Michael Mann -- the paleoclimatologist who came up with "the hockey stick" --
would be difficult to parody. Three of four allegations are dismissed out of hand at the outset: the inquiry announces that, for "lack of credible evidence", it will not even investigate them. (At this, MIT's Richard Lindzen tells the committee, "It's thoroughly amazing. I mean these issues are explicitly stated in the emails. I'm wondering what's going on?" The report continues: "The Investigatory Committee did not respond to Dr Lindzen's statement. Instead, [his] attention was directed to the fourth allegation.") Moving on, the report then says, in effect, that Mann is a distinguished scholar, a successful raiser of research funding, a man admired by his peers -- so any allegation of academic impropriety must be false.
You think I exaggerate?
"This level of success in proposing research, and obtaining funding to conduct it, clearly places Dr. Mann among the most respected scientists in his field. Such success would not have been possible had he not met or exceeded the highest standards of his profession for proposing research..."
******
In short, the case for the prosecution is never heard. Mann is asked if the allegations (well, one of them) are true, and says no. His record is swooned over. Verdict: case dismissed, with apologies that Mann has been put to such trouble."

Also, about 3 years ago Mann filed a defamation suit in Wash DC and falsely claimed to have won the Nobel prize. Didn't even cause a ripple at PSU.
