Joe Romm tells me to “retract [my] libellous misinformation and apologise to Michael Mann”. He is complaining about my suggestion that the various inquiries supposedly vindicating the Climategate emailers have further diminished the credibility of climate science, rather than restoring it.

I think the only issue of substance in his complaint is the charge that I failed to notice that there were two Penn State investigations of Mann, not one, and that both had cleared the accused. Of course I was aware of the form of the inquiry, though I concede that the post was not as clear about the two phases as it should have been.
