NFL Officials Over-Inflated Patriot Balls

One of the ironies of the NFL’s conduct in this affair is that it can be established that NFL officials (under the supervision of NFL Executive Vice President Troy Vincent) over-inflated Patriot balls at half-time, the only proven tampering with Patriot balls. Brady and the Patriots were unaffected by the overinflation by NFL officials, as […]

More on Deflategate

By converting football pressures to ball temperatures under the Ideal Gas Law, it is possible to conveniently show Colt and Patriot information – transients, simulations and observations – on a common scale. I’ve done this in the diagram shown below, and, in my opinion, it neatly summarizes the actual information. Commentary follows the figure. Figure 1.  Transients as […]

Deflategate and Errors in the Wells Report

Readers in the U.S. are doubtless aware of the “Deflategate scandal”, in which the NFL alleged that Tom Brady, the greatest quarterback of his generation, had conspired with an equipment manager and locker room attendant, to deflate a microscopic amount of pressure from footballs in the AFC championship game. The NFL seemed to be completely […]

Rahmstorf’s Third Trick

Rahmstorf et al 2015 Figure 5 shows a coral d15N series from offshore Nova Scotia (see left panel below). The corresponding plot from the source is shown on the right.  Original captions for both follow.  There’s enough information in the figures and captions to figure out Rahmstorf’s next trick. See if you can figure it out […]

Rahmstorf’s Second Trick

The Rahmstorf et al reconstruction commences in AD900 even though the Mann et al 2009 reconstruction goes back to AD500.  Once again, this raises the obvious question: why didn’t Rahmstorf show values before AD900?  Are these results adverse to his claims? Once the question is posed, you can guess the answer. 

Rahmstorf’s First Trick

In any article by Mann and coauthors, it is always prudent to assume that even seemingly innocent choices use up a researcher degree of freedom – to put it nicely. For example, Rahmstorf et al focus on their “AMOC index” in the period ending 1995 and show their AMOC index up to as shown below.

Jones and Dixon Refute Conspiracy Theorist Lewandowsky

Jonathan Jones and Ruth Dixon have published (see Ruth’s blog here) a comment  in Psychological Science on conspiracy theorist Stephan Lewandowsky’s Hoax article, much discussed at CA at the time.  Although their statistical points are incontrovertible and clearly expressed, it took considerable persistence – see timeline here. Their first and longer original article was submitted to a different […]

Reductio ad mannium

The new article by Rahmstorf and Mann (see RC here) has been criticized at WUWT (here here) for making claims about Atlantic Ocean currents based on proxies, rather than measurements. (Also at Judy’s here)   But it’s worse, much worse than we thought. Rahmstorf and Mann’s results are not based on proxies for Atlantic current velocity, but […]

How Weaver Ignored Corcoran’s Segue

Four of the incidents in J Burke’s background chronology in Weaver v National Post (the January 27, 2005, February 15, 2005, August 2006 and February 27, 2008 incidents) relate, either in whole or in part, to a dispute between Weaver and National Post on whether Weaver had dismissed our research as “rubbish” or “balderdash” or a like […]

Weaver: “I do not lobby for more climate funding”

J Burke’s decision contains a chronology of prior interactions between Weaver and National Post, much of which, when closely examined, is highly misleading. In today’s post, I’m going to discuss one small but interesting issue: Weaver’s claim that he “did not lobby for climate funding”. J Burke referred to this when she said that Weaver […]
