Schmidt’s recent post on Yamal advocated the following “conspiracy theory”: McIntyre got the erroneous idea that studies were being done, but were being suppressed if they showed something ‘inconvenient’. This is of course a classic conspiracy theory and one that can’t be easily disproved. Accusation: you did something and then hid it. Response: No I […]
Hansen’s twin pit bulls, Tamino and Gavin, have launched into a spirited defence of Mannian paleo-phrenology at realclimate here, with a counter-discussion at Bishop Hill here.
If anyone feels like sticking needles in their eyes, I’d appreciate assistance in trying to figure out Mannian verification statistics. Even when Mann posts up his code, replication is never easy since they never bothered to ensure that the frigging code works. Or maybe they checked to see that it didn’t work. UC’s first post […]
Tamino has recently re-iterated the climate science incantation that Mann’s results have been “verified”. He has done so in the face of the fact that one MBH98 claim after another has been shown to be false. In some cases, the claim has not only been shown to be false, but there is convincing evidence that […]
This post got deleted in the server crash. I typically post up from written text, but usually do a final edit as I input onto the blog, so the present note will probably differ a little from what I posted up yesterday, but probably not materially. Mann did not present anything germane that had not […]
I’m posting up our July 2005 review of Wahl and Ammann. The recently accepted version is here. I’m posting this up for a variety of reasons. Mann relied heavily on Wahl and Ammann in his NAS panel testimony (which wasn’t even online as accepted last week) and so it’s hard to finish off the discussion […]
Mann cited Wahl and Ammann’s recently released paper at NAS (which was not available to us in time for the NAS panel, although I’d seen and reviewed an earlier draft.) After reading it, Per said that he thought that the reviewers had done a lousy job. Now I was only a reviewer for the first […]
For the first time, a member of the Hockey Team (Ammann and Wahl) has admitted that the verification r2 for the early steps of MBH98 are catastrophic. Results confirm our calculations – as we predicted. They have not explained the justification for issuing a press release that all our claims were "unfounded" and UCAR has […]
I’ve just noticed at the UCAR website that Ammann and Wahl now say that their CC re-submission was “provisionally accepted” on Dec 12. I have no information on what a "provisional acceptance" means, but it’s certainly a coincidence that the “provisional acceptance” occurred only 3 days after GRL agreed to send their previously rejected GRL […]
Continued from Part 1, Part 2, Part 3 OK, back to Ammann at AGU, his answer to the cross-validation R2 and my offer to him after our lunch. I think that asking for the cross-validation R2 was a good one-bite question at several different levels. First, it’s objective and any prevarications are noticeable to the […]
