In Dec 2004, Steig and Schmidt wrote The Antarctic Peninsula, site of the now-defunct Larsen-B ice shelf, has warmed substantially. On the other hand, the few stations on the continent and in the interior appear to have cooled slightly (Doran et al, 2002; GISTEMP). At first glance this seems to contradict the idea of “global” […]
David Bader, PhD, the Director, Program for Climate Model Diagnosis and Intercomparison, writes today seeking to “clarify several mis-impressions on your “climateaudit.org” web site” regarding the archiving of Santer’s data, the correspondence being shown below. Readers may recall an earlier post here in which I requested data from Santer et al 2008, in response to […]
One of my brothers forwarded this to me with the caption: “Isn’t it comforting to know that when you are about to become a bear’s breakfast, your buddy is standing there taking photos?”
Yesterday Ross and I submitted an article to IJC with the following abstract: A debate exists over whether tropical troposphere temperature trends in climate models are inconsistent with observations (Karl et al. 2006, IPCC (2007), Douglass et al 2007, Santer et al 2008). Most recently, Santer et al (2008, herein S08) asserted that the Douglass […]
ABSTRACT: A new method is proposed for exploring the amplification of the atmosphere with respect to the surface. The method, which I call “temporal evolution”, is shown to reveal the change in amplification with time. In addition, the method shows which of the atmospheric datasets are similar and which are dissimilar. The method is used […]
Once upon a time, in the mists of time (Feb 2008), long before climate scientists had “moved on”, realclimate featured a post entitled Antarctica is Cold? Yeah, We Knew That, in which Spencer Weart, as noted by Pielke Jr, observed: . . . we often hear people remarking that parts of Antarctica are getting colder, […]
Image by mark van de wouw via Flickr For discussion of new study. by Steig (Mann) et al 2009. Data: Data sets used in this study include the READER and AWS data from the British Antarctic Survey. SI Tables 1 and 2 provide listings. They leave out station identifications (a practice that “peer” reviewers, even […]
Mann said: Although 484 (~40%) pass the temperature screening process over the full (1850–1995) calibration interval, one would expect that no more than ~150 (13%) of the proxy series would pass the screening procedure described above by chance alone. Reader DC said: Of the 484 proxies passing the 1850-1995 significance test, 342 also passed both […]
In a recent CNN interview discussed at RC here, Joe D’Aleo said: Those global data sets are contaminated by the fact that two-thirds of the globe’s stations dropped out in 1990. Most of them rural and they performed no urban adjustment. And, Lou, you know, and the people in your studio know that if they […]
One of the ongoing Team mantras has been that the Mann hockey stick has been supported by a “dozen independent studies”. Obviously, I’ve disputed the claim that these studies are “independent” in any non-cargo cult use of the term “independent”. A new article by Jones and multiple coauthors (Holocene 2009) comments on this issue.
