As a preamble and reprise, I think that it is reasonable for Cowtan and Way to take exception with HadCRU’s failure to estimate temperature in Arctic gridcells and to propose methods for estimating this temperature. At a time when the climate community argued that differences between the major indices and accessibility to CRU data didn’t […]

A trivia question today for CA readers.
Yet another propaganda essay masquerading as a scientific paper has been published (SI here) in the journal, Environmental Research Letters. The latest entry, Quantifying the Consensus on Anthropogenic Global Warming in the Scientific Literature, written by a team of activist bloggers led by John Cook of the antithetically named Skeptical Science blog, attempts to further […]
John Cook, whose crush on Lewandowsky continues unabated, asked various blogs, including Climat Audit, to direct readers to another online survey. Lucia has discussed the survey here. The links to the survey from SKS here is http://survey.gci.uq.edu.au/survey.php?c=1R9YT8YMZTWF and from Rabett hereis http://survey.gci.uq.edu.au/survey.php?c=II7WP4R4VRU7. More IDs are available at Lucia’s. It is easy enough to access both […]
Last fall, Geoff Chambers and Barry Woods established beyond a shadow of a doubt that no blog post linking to the Lewandowsky survey had ever been published at the Skeptical Science (SKS) blog. Chambers reasonably suggested at the time that the authors correct the claim in the article to reflect the lack of any link […]
Lewandowsky et al stated that “links were posted on 8 blogs (with a pro-science science stance but with a diverse audience”. Lewandowsky identified the eight blogs (in an email to Barry Woods) as: Skeptical Science, Tamino, Bickmore, the UU-UNO Clmate Change Task Force (trunity), Ill Considered, Mandia, Deltoid and Hot Topic. The relevant posts at […]
Anthony Watts draws attention to a new Nature article (LI et al 2011) purporting to reconstruct El Nino activity. The Supplementary Information shows a very obvious Chladni pattern, that went unnoticed by the Nature reviewers. The eigenvector shown here is what one would expect from principal components carried out on spatially autocorrelated data on a […]
Two new things on the Divergence Problem. The IPCC First and Second Drafts did not contain a whisper of a mention of the divergence between ring widths and density in the second half of the 20th century, although this is rather an important issue. It came up at the NAS Panel and was completely unresolved […]
What is ironic in Mann’s citation of Cook as authority that paleoclimatologists need not provide a range of verification statistics is that Cook et al.  actually provide a suite of verification statistics, headed by the R2 statistic, which Mann et al. now object to.
