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 not retracted the press release. I’ve left this as a sticky for a little while since it’s rather fun.
Ammann and Wahl is now in press. When I saw him in San Francisco, Ammann was not going to report the verification r2. I urged him to report the verification r2, urging him in as nice a way as possible not to "replicate" Mann to the extent of once again withholding the verification r2 statistic. He didn’t seem so inclined. That’s one of the reasons why I’ve turned the heat up on Ammann (who seems nice enough but who has fallen in with a rough crowd.)
Guess what – buried deep in Ammann and Wahl  are the verification r2 scores for their MBH emulation. Maybe our complaints to UCAR and publicity at the blog made them decide that wisdom was the better part of valor. Aside from risking scientific misconduct. Or maybe the "provisional acceptance" by Climatic Change included the requirement that they disclose these results. Regardless, the results are on the table. (How long did it take?) They completely vindicate our claims in GRL. The verification r2 for the 15th century step reported by A&W is 0.018. Some steps are even worse. Here is their table. I’ll parse through their commentary a little later and post some more news. These are the guys that issued a UCAR press release saying that all our results were "unfounded".
