Climate Audit: Is being offensive really the best defence?

In a breathless update on the tawdry Wegmangate tale of plagiarism, mining promoter and amateur statistician Stepehn McIntyre (proprietor of Climate Audit) has tried to distract from the case at hand by imagining an earlier instance of plagiarism, allegedly committed by Edward Wegman’s victim, Raymond Bradley.

For those just catching up, the blogger Deep Climate and his research partner John Mashey have produced a document that shows just how extensively the once-respected statisitician Wegman cribbed from one of his apparent victims (Ray Bradley) in a report that Wegman produced for Congress. Mashey argues that Wegman’s errors and plagiarism were more than merely unprofessional: he says that they constitute a barefaced and illegal effort to mislead Congress. George Mason University is currently investigating the plagiarsim charges.

McIntyre has chosen to run interference on that complaint not by actually defending Wegman (whose shoddy work seems increasingly indefensible) but by attacking Ray Bradley, one of the authors of the iconic “hockey stick graph” that Wegman had been hired to attack. McIntyre points out in his post that Bradley had earlier used a series of figures from a 1976 book by H.C. Fritts and, according to McIntyre, provided inadequate credit.

This, however, seems less like plagiarism and more like an effort to build good science on a solid foundation.

Joe Barton: Misleading Congress; Misleading America

Rep. Joe Barton, already implicated in an effort to mislead Congress about the science of climate change, is obviously choosing offence as his best possible defence, renewing his slander of Penn State climate scientist and “Hockey Stick” author Dr. Michael Mann.

As then-co-chair of the House Energy and Commerce Committee, Barton was responsible in 2006 for inviting the increasingly controversial statistician Edward Wegman to prepare a critique of Mann’s iconic hockey-stick-shaped graph illustrating a 1,000-year climate reconstruction. Although Barton has denied that he had a previous relationship with Wegman, implying that the subsequent report and hearing were not a set-up, John Mashey has documented the extensive direction that Barton provided to Wegman through Barton staff member Peter Spencer.

Hockey Stick Basher Wegman Under Investigation

Is Talk of Lawsuit A Trick to Hide His Decline?

George Mason University has confirmed that it is investigating its Professor Edward Wegman, the statistician who was point man in the 2006 political attack on the so-called “hockey stick” graph.

Wegman, who was chair of the National Academy of Sciences’ (NAS) Committee on Applied and Theoretical Statistics, was tapped in ‘06 by Republican representatives Joe Barton and Ed Whitfield to assemble a so-called “expert panel” to critique the famous hockey stick, a graph illustrating a thousand-year temperature record as reconstructed by climate scientists Michael Mann, Raymond Bradley and Malcolm Hughes. But Silicon Valley entrepreneur John Mashey has since demonstrated that, rather than convene a group of experts, Wegman tapped a couple of grad students and together they produced a report that was generously plagiarized from Bradley’s own work and then twisted - or just misrepresented - to appear to undermine the hockey stick and its creators.
