The Ocean2K “Hockey Stick”

The long-awaited (and long overdue) PAGES2K synthesis of 57 high-resolution ocean sediment series (OCEAN2K) was published a couple of weeks ago (see here here). Co-author Michael Evans’ announcement made the results sound like the latest and perhaps most dramatic Hockey Stick yet: Today, the Earth is warming about 20 times faster than it cooled during the past 1,800 […]

Op Ed on Deflategate

In Financial Post here. My submitted version was a little harsher. #deflategate For related blog posts, see tag here.

Did McNally Inflate One Football in the Washroom?

In today’s post,  I’m going to show the Deflategate data from a new perspective.   Rather than arguing about whether the Patriots used the Logo gauge, I’ve assumed, for the sake of argument, the NFL’s conclusion that the Non-Logo gauge was used, but gone further (as they ought to have done). I’ve “guessed” the amount of […]

Letter to Daniel Marlow on Exponent Error

On June 29, I sent a letter to Ted Wells, notifying him of the erroneous description of key figures in the Exponent report, but did not receive any acknowledgement.  In the presumption that Daniel Marlow of Princeton is more likely to be concerned about the erroneous research record (as well as having obligations that the […]

Exponent’s Trick to Exaggerate the Decline

In an earlier article,  I pointed out that essential figures in the Exponent report contained (what appeared to be) an important misrepresentation: that transients purporting to represent Logo gauge initialization had not really been initialized with the Logo gauge.  The same point was later (and independently) made in a technically oriented sports blog.  Exponent’s misrepresentation […]

Who “Told” Exponent Not to Consider Switching Scenario?

The transcript of the Brady appeal before Goodell has been released and it’s astonishing to see how the sausage was made.  It raises many issues, one of which I’ll discuss in today’s post.

Goodell and Deflategate Science

Yesterday, Roger Goodell released his decision on the Brady appeal. Most of the early discussion has been about Brady’s destruction of his cell phone. Brady has contested the NFL’s characterization of this incident here (see cover here), saying that he had replaced a broken phone; that they had already told the NFL that Brady was not going to […]

Raymond Bradley and the Grand Old Duke of York

In today’s post, I’ll return to more typical Climate Audit programming.  Upside-down Mann’s mentor, Raymond Bradley, has somewhat surprisingly published an article (Balascio et al 2015) that supports a longstanding Climate Audit criticism of varve proxies. Bradley and coauthors did not report that their interpretation of an important Baffin Island series is upside-down to the […]

Ruling out high deflation scenarios

Further to my series of posts on Deflategate, reader chrimony observed that my statistical analysis had shown that it was possible that there had been no tampering, but had not excluded the possibility of tampering.  This is a sensible observation, but raises the question of whether and how one could use the available statistical information […]

Exponent’s Transients: Bodge or Botch?

In my first writeup, I observed that Exponent’s Logo transients appeared to be bodged too high, even with their unwarranted and adverse use of 67 deg F initialization (Exponent’s “temperature trick”). In today’s post, I’ve taken a closer look at the seemingly questionable calculation of the transients at 67 deg F, showing that the Patriot […]
