Deep Climate catches Steve McIntyre in a particularly outrageous piece of quote mining. McIntyre strips a sentence written by Trenberth from its context to make it appear that Trenberth was saying that Jones was an IPCC author for the first time, when in fact Trenberth was saying that Jones was an IPCC lead author for…

Deep Climate continues his examination of the Wegman report. It would seem that Wegman’s “reproduction” of McIntyre’s results amounted to nothing more than running McIntyre’s code without understanding what it did. And while Mann’s “short centring” method does tend to produce a hockey-stick McIntyre greatly exaggerated the extent that it does so.

The discussion involving Judith Curry and The Hockey Stick Illusion has continued at Collide-a-Scape, with posts on the views of Judith Curry (Curry did admit to getting one of her ten points wrong, but not the other nine) and those of Gavin Schmidt. Steve McIntyre’s comments in the second thread provides another case where readers…

Following vindications from the NRC panel, the independent Penn State Committee, the House of Commons report, the International Panel, the Penn state Investigatory Committee, the Independent Climate Change Email Review has reported On the specific allegations made against the behaviour of CRU scientists, we find that their rigour and honesty as scientists are not in…

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…

Steve Mosher and Steve McIntyre have alleged that the stolen CRU emails prove that Keith Briffa had violated IPCC rules in when working on the 4th Assessment Report. They can’t point to any particular IPCC rule and rely on a creative interpretation of an email from Jonathan Overpeck, which Mosher claims means that Briffa “should…

Deep Climate has been reading the stolen emails that Steve McIntyre didn’t mention: Arguing from a cherrypicked selection of quotes from the “Climategate” emails, McIntyre has claimed that IPCC authors Chris Folland and Michael Mann pressured Briffa to submit a reconstruction that would not “dilute the message” by showing “inconsistency” with multi-proxy reconstructions from Mann…

Rose and McIntyre

Deep Climate documents what happened when Steve McIntyre combined his talent for making mountains out of molehills with David Rose’s talent for fabrication: So in summary, we have a nonsensical accusation of “artful” manipulation of a key graph. And we have a fake “blowup” from the Mail on Sunday that contains important differences with the…

Rosegate

Imagine, if you will, that the emails stolen from CRU had included fawning comments from an MSM journalist to a climate scientist like this: As a veteran member of the MSM (Vanity Fair and the UK’s Mail on Sunday) may I state for the record: Sir, I salute you. Bravo! or this: without Steve’s brilliant…
