This has been bubbling inside me for quite some time now. Maybe it started some years back when Dr. Michael Mann, the hockey stick guy, was on a TV panel show and someone suggested that climate affairs were so bad that it made her/him want to cry. As if on cue, Mann generated crocodile tears, pretending to lament the situation of our climate. It made me want to puke.
But I have a lot of impressions of Mann … perhaps foremost, that while his so-called Hockey Stick is pseudoscience at best, it is very detailed work that requires a great deal of intelligence and effort, even if he was probably exaggerating his case, perhaps even engaging in creative accounting. Steve McIntyre, the Canadian mining engineer who took apart the stick piece by piece, had to devote tremendous effort to replicate Mann’s efforts, not easily dissembled and beyond the reach of us mere mortals. What we found was that tree rings are a complicated science, and without a strong working knowledge of statistics cannot be assembled in a way that sends a “temperature signal” from the past to the present.


I am currently listening to a daily podcast called Climate Change on Trial, hosted by two Irish film makers, Phelim McAleer and Ann McElhinney. They are covering the defense of the lawsuit filed in 2012 by Michael Mann against pundit Mark Steyn and blogger Rand Simberg. There are ten episodes available so far, and guess who has listened to all of them? I am rapt, even as so far it is been Mann and company making their case and being cross examined. Real fun is in store, more to follow the very first defense witness, prominent statistician, Abraham J. Wyner of the Wharton School.
Wyner comes off as a classic nerd who loves his work. Part of his work in statistics is about sports, and I think his podcast, which I have not located yet, draws a large audience because he gets beyond the dull science. Anyway, Wyner testified that Mann’s hockey stick work was “manipulative,” meaning that many outcomes were possible by torturing that data, but that Mann had an apparent predetermined objective, featured prominently by Al Gore and now the cause of trillions of wasted dollars in search of net zero, the hockey stick. Talk about being juiced.
