Ammann and Wahl Little Whopper Rejected

GRL has rejected the Ammann and Wahl Little Whopper (shortly after Climatic Change accepted the Big Whopper). We previously posted up our Reply to the Little Whopper here. You can see previous discussion of this by the category "Wahl and Ammann". Since the Comment is not being published, neither is the Reply. I wonder whether […]

IPCC 4AR and Ammann

Luboà…⟠Motl pointed out that IPCC "needs" Ammann and Wahl in a peer reviewed journal. Let’s re-visit some curious timing issues, which Ian Castles brought up before and which need to be re-examined with the re-submission. The IPCC WG1 timetable (thanks to Ian for this) says the following: Third Lead Author meeting, December 13 to 15, […]

Ammann and Wahl – July 2005 Review

I’m posting up our July 2005 review of Ammann and Wahl. The recently accepted A&W version is here. I’m posting this up for a variety of reasons. Mann relied heavily on Ammann and Wahl in his NAS panel testimony (which wasn’t even online as accepted last week) and so it’s hard to finish off the […]

Peer Reviewing Ammann and Wahl #1 – The Correspondence

Mann cited Ammann and Wahl’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 […]

Verification r2 Revealed!!!

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 […]

UCAR and the NAS Panel

Readers of this site are familiar with various efforts by UCAR and UCAR personnel to discredit us, ranging from the April 6, 2005 presentation in Washington by Ammann, Bradley and Crowley discussed here , the long-standing effort by Ammann and Wahl to discredit us leading to the UCAR press release of May 11, 2005, announcing […]

The A&W Little Whopper

For your reading pleasure, here is our Reply to Ammann and Wahl (GRL). as submitted on Jan. 29, 2006. You don’t have access to the A&W Comment itself; [update: now here ] but if you re-read the Huybers article, it has the same points without all the mischaracterizations and misrepresentations of A&W. A&W also have […]

Ammann Chronology

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 […]

Ammann at AGU: the Answer

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 audience. Second, you can get to the point […]

11 Ammann Mentions in Mann's Barton Letter

As I was writing up my note on Ammann at AGU, I re-read Mann’s reply to Barton, which mentions "ammann" no fewer than 11 times, usually as an "independent" scientist confirming his results. I’ve collected the mentions here, which make for some merry reading. Then I’ll discuss exactly how "independent" Caspar Michael Ammann (should we […]
