As far as I know, Michael Mann has never lifted a finger to correct the misperception conveyed and constructed by his “hockey stick” curve.
Dr. Michael Mann will be investigated by Penn State University following the release of more than a thousand emails from the world’s top climate scientists. The university said it was “looking into the matter” and “reviewing the concerns that have been raised.” (Penn State University)
The fallout from the Climategate event continues as one of its primary participants, Dr. Michael Mann, is to be investigated by his employer, Penn State University. Among the more than one thousand emails released on the Internet, Mann featured prominently in many of them oftentimes making rather controversial comments.
Mann serves as the director of the Earth System Science Center at Penn State and has long been one of the more controversial figures in the debate about manmade climate change. He is the author of the infamous ‘hockey stick’ graph which was used by Al Gore in “An Inconvenient Truth” but later was proven to be inaccurate.
