The Australian‘s coverage of the story of the emails stolen from CRU has been extensive — my Factiva search found that there have published 85 articles so far that mention the matter, with repeated allegations that the emails showed that the scientists were corrupt, had acted dishonestly and that the science could not be trusted.…

Deep Climate on McIntyre’s trick

Deep Climate investigates Steve McIntyre’s claim that, in the IPCC TAR, Michael Mann used a “trick” to “hide the decline” in Briffa’s tree-ring proxy. You will be shocked, just shocked, to discover that: So, once again, the accusation that Mann “truncated” or “chopped off” the data set is proven to be utterly false.

McIntyre’s trick

Steve McIntyre claims: One version of the trick is used in IPCC TAR. In this version, Mann replaced post-1960 values of the Briffa reconstruction with instrumental values, then did a smooth, then truncated the Briffa reconstruction back to 1960. Post-1960 instrumental values affected the smooth by the arithmetic of the smoothing filter. Steven Mosher claims…

In his latest column Lawrence Solomon misrepresented an article by Mike Hulme, claiming that Hulme wrote that the IPCC consensus was phoney. Of course it was Solomon’s story that was phony, as Hulme explained: “I did not say the ‘IPCC misleads’ anyone – it is claims that are made by other commentators, such as the…

Andrew Bolt has written a post where he pretends that comments made by Andrew Lacis about the first order draft of the summary of chapter 9 of AR4 WG1 are actually aboout the published report. Andrew Revkin asked Lacis what he thought about the published report: “The revised chapter was much improved,” he said. “That’s…

Bidisha Banerjee and George Collins have written the definitive account of the error in the WG2 report about Himalayan glaciers: Dozens of articles and analyses of this situation, whether dashed-off blog posts or New York Times coverage, exhibit a curious consistency. Not a single article or analysis appears to include all relevant issues without introducing…

Leakegate scandal grows

There have been new developments in Leakegate, the scandal swirling about reporter Jonathan Leake, who deliberately concealed facts that contradicted the story he wanted to spin. Deltoid can reveal that Leake was up to the same tricks in his story that claims that the IPCC “wrongly linked global warming to natural disasters”. Bryan Walker has…

Leakegate

Jonathan Leake recently wrote a story alleging that the statement in the IPCC AR4 WG2 that up to 40% of the Amazon forest could vanish due to climate change was “bogus”. Deltoid can now reveal that Leake deliberately concealed the fact that Dan Nepstad, the author of the 1999 Nature paper cited as evidence for…

You can add the George Kaser to the list that includes Pielke Jr, Latif and Lal. It’s like he can’t help himself. Rose claimed that he was told by Kaser that he wrote to Lal: I’m not the only person in disagreement with Dr Lal. Georg Kaser, the Austrian glaciologist, insists (indeed, he told me…

Rosegate scandal grows

There have been new developments in the Rosegate, the scandal about the way David Rose sexed up his story about the IPCC and the Himalayan glaciers. Andrew Revkin has posted an email from Murari Lal, the scientist that Rose verballed: I am not a Glaciologist but a Climatologist and the statement attributed to me in…
