Terence Corcoran whopper: Mann’s hockey stick “eliminated some of the data from 1960 forward … and then spliced on actual temperature data”

Terence Corcoran may well have just unleashed the National Post’s biggest whopper yet about climate science – and that’s saying something.

Corcoran’s commentary on the recent Russell “climategate” email review lays one error-laden defamation on top of another, as he attempts to demonstrate that the report “provides plenty of evidence that climate science has been and remains an uncertain shambles”. Oh, and apparently the review “portrays climate science as a field filled with uncertainty, debate, lack of openness, data hoarding and ill-will.”

Along the way, Corcoran even manages to confuse a little known Phil Jones graphic with Michael Mann’s “hockey stick” millenial temperature reconstruction. This leads to the astonishing (and entirely wrong) accusation that the hockey stick creators “eliminated some of the data from 1960 forward … and then spliced on actual temperature data”. Yet neither the “hockey stick” graph (the real one) nor the associated Mann et al study are mentioned in the report at all!

McClimategate continues: Yet another false accusation from McIntyre and McKitrick

How do they get away with it? That’s the inevitable question as I examine one of the most specious – and despicable  – “climategate” allegations from contrarians, namely the oft-repeated claim that climate scientists at East Anglia University’s Climate Research Unit inappropriately adjusted certain tree-ring temperature proxy data to provide a better match with instrumental temperature record.

In an extraordinary interview with FoxNews in December of last year, economist Ross McKitrick alleged that scientists were “faking the match” between proxy and temperature data. McKitrick averred this was “not being honest with the reader” and even invoked a comparison to  falsified experimental medical research.  Stephen McIntyre of  ClimateAudit recently claimed that the “artificial correction” seemed “to have entered the CRU toolkit” (in his submission to the U.K. parliamentary committee examining  allegations arising from stolen CRU emails, no less).

Yet a close examination of the computer code and ensuing research bears out the key contention of the firm rebuttals from East Anglia University, as well as CRU scientist Tim Osborn, namely that the specific adjustments in question were for private exploration only and never incorporated into CRU scientists’ subsequent published research temperature reconstructions. So, once again, McIntyre and McKitrick have made odious and unfounded accusations, based on non-existent evidence. They should withdraw these specious allegations immediately.

National Post’s Lawrence Solomon claims Google censors search results

Just when you thought commentary on the CRU hacked emails could not get any more absurd, along comes National Post columnist and “environmentalist” Lawrence Solomon to up the ante. Believe it or not, Solomon’s latest over-the-top screed accuses Google of censoring search results to downplay the so-called Climategate scandal. But, as they say in the newspaper biz: “Check a story, lose a story”.

Mojib Latif slams Daily Mail

David Rose

In comments, several readers suggested that I examine a recent report from the U.K. newspaper the Daily Mail that attempts to tie the research of modeller and IPCC author Mojib Latif to the current cold spell in Europe.  Now that Latif has responded to this latest distortion of his views in an interview with the Guardian, I’m happy to oblige.

And, while I’m at it, I’ll also take a look at the short and dubious track record of newly-minted contrarian climate “investigative journalist”  David Rose, whose very first climate change article was an overview of Climategate “research” from Steve McIntyre, with generous assistance from Ross McKitrick.

McIntyre provides fodder for skeptics

[This post was updated on December 12 to provide additional context that strengthens the original analysis – see below for details.]

This so-called Climategate is really getting out of hand, isn’t it?

Steve McIntyre has published allegations – twice now – that an internal IPCC authors’ debate about the inclusion of Briffa’s tree-ring reconstruction in a key figure from the 2001 WG1 Third Assesement Report was driven by concern about the post-1960 “decline” in tree-ring widths, a decline that showed a marked divergence with the instrumental tempertaure record.

The Climategate Letters show clearly that the relevant context is the IPCC Lead Authors’ meeting in Tanzania in September 1999 at which the decline in the Briffa reconstruction was perceived by IPCC as “diluting the message”, as a “problem”, as a “potential distraction/detraction”. [Emphasis added]

McIntyre even claims that lead author Michael Mann worried that showing the series with this decline would give “fodder” to “skeptics”.

But even a cursory examination of the emails in question shows that the discussion was really about other aspects of the reconstruction, specifically obvious discrepancies between Briffa’s reconstruction and the other two under consideration over the major part of the reconstruction’s length. Thus, once again, McIntyre’s speculations are shown to be utterly without foundation.

Even worse, McIntyre left out intervening sentences within the actual proffered quotes in what appears to be an unsophisticated attempt to mislead.

The Times: Climate e-mail hackers “aimed to maximise harm to Copenhagen summit”

According to TimesOnline, investigators of the CRU email theft (dubbed SwiftHack or Climategate) have concluded that the release of the stolen material was held back for weeks in order to cause maximum damage to the upcoming Copenhagen conference.

This development, along with new reports of breakins and other attacks at the University of Victoria, should finally lay to rest the baseless rumour that the hacked email archive was assembled at CRU as part of a contingent FOI response and released by an inside whistleblower, a canard that was started by – wait for it – none other than Steve McIntyre himself!
