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.
A blog article here reviews the “standing joke” of Mann’s stubbornness in refusing to correct the wrong locations of MBH98 in the recent Mann et al 2007 network, where, as I observed, the prior errors are perpetuated without apology, even though the incorrectness of the locations has long been known to Mann. In a routine […]
Earlier today, I reported that I had been unable to access their server using R even to get a tiny data set. (I haven’t been working on NASA GISS data and haven’t downloaded anything much from them for months.) The following simple script failed for me (and for Roman in New Brunswick, Canada), but, strangely […]
