michael mann is really pretty sad. He has been rebuked by the Nobel committee. He is suing over harm to his reputation, so its funny that he is trying to inflate his reputation in advance. Mark has more on this :
Mann's embellishment has placed him in a situation where his claims are being countered by the Nobel organization itself. Mann's claim, rather than boosting his credibility actually risks having the opposite effect, a situation that was entirely avoidable and one which Mann brought upon himself by making the embellishment in the first place. The embellishment is only an issue because Mann has invoked it as a source of authority is a legal dispute. It would seem common sense that having such an embellishment within a complaint predicated on alleged misrepresentations may not sit well with a judge or jury.
This situation provides a nice illustration of what is wrong with a some aspects of climate science today -- a few scientists motivated by a desire to influence political debates over climate change have embellished claims, such as related to disasters, which then risks credibility when the claims are exposed as embellishments.
