Let no one say that we at climateaudit do not contribution to coalition building. In the bibliography to Wahl and Ammann [Clim Chg 2006], we see the following citation: Wahl, E., Ritson, D. and Ammann, C. accepted, Reconstruction of century-scale temperature variations, Science If you can’t get accepted at GRL, you can always try Science.
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’m not sure that there’s a huge demand for more linear algebra on MBH98, but here’s the rest of the proof that the NH temperature index in an MBH98-type calculation is simply a linear combination of proxies and, when only one temperature PC is reconstructed, the weights are proportional to the correlation between each proxy […]
What I’m going to show here is that the MBH98 method can be reduced to a few lines of code and, in doing so, show some other interesting results as well. Today I’m just going to get to the reconstructed temperature PCs, but I’ll show that these are linear in the proxies and later show […]
I’ve got something that’s a little bit amusing today. In MM03, we pointed out collation errors in pcproxy.txt (which I’ve recently hypothesized was used in the version of Rutherford, Mann et al [2005] submitted in July 2003 and was laundered after MM03). We pointed out that the PC series all seemed to start one year […]
This is pretty much the one-year anniversary of our two 2005 articles in GRL and E&E. There’s a very interesting assessment of the status of the debate at Europa Tribune here. About one year ago, January 2005, an article of Steve McIntyre and Ross McKitrick was published in the Geophysical Research Letters with harsh criticism […]
I’m trying to use "hissy fit" purely descriptively and not in an ad hominem sense. I can’t think of any other way to describe today’s postings at Daily Kos – scroll down. A reader posted up a pretty sensible and mundane question about RegEM – the new magic bullet from the nomadic Hockey Team. I […]
Over at Daily Kos, Mann says that the Nomads (this is a new candidate name for the Hockey Team) have moved on and that RegEM, as in Rutherford, Mann et al [2005], is the new sheriff. At the end of the day, it’s hard to see how the RegEM method avoids any of the BàÆà⻲ger […]
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 […]
I quickly mentioned BàÆà⻲ger and Cubasch [2005] which was published in December and meant to post up some further comments at the time, but forgot to do so. I was reminded of this by the question of a reader at Daily Kos . Let me mention first that BàÆà⻲ger and Cubasch is a really interesting […]
