An influential 2006 congressional report that raised questions about the validity of global warming research was partly based on material copied from textbooks, Wikipedia and the writings of one of the scientists criticized in the report, plagiarism experts say. Review of the 91-page report by three experts contacted by USA TODAY found repeated instances of passages lifted word for word and what appear to be thinly disguised paraphrases. The evidence has become overwhelming that recent global warming is unprecedented in magnitude and speed and cause (see “Two more independent studies back the Hockey Stick and below). Indeed, as WAG notes, within a few decades, nobody is going to be talking about hockey sticks, they will be talking about right angles or hockey skates (see chart above). The disinformers (and the confusionists who Curry favor with them), however, are not merely oblivious to the multiple, independent lines of scientific investigation that lead to that conclusion. They have for over a decade tried to discredit one small piece of that underlying analysis, the Hockey Stick graph developed by Michael Mann, Raymond S. Bradley & Malcolm K. Hughes — continuing their obsession even after that analysis was largely reaffirmed by a 2006 report from the National Academy of Sciences, the “Supreme Court of science.” A cornerstone of the disinformer’s ultimately self-destructive attack on climate science is a 2006 report, commissioned by Rep. Joe Barton (R-TX) and Rep. Ed Whitfield (R-KY), and led by George Mason University statistician Edward Wegman, who is now himself under investigation by GMU. You can find all the details you could want about the shoddy analysis of the report at Deep Climate — including his “methodical demolishing of any hint of statistics” in the report, as John Mashey puts it in the comments. Here’s more from the stunning USA Today piece: “It kind of undermines the credibility of your work criticizing others’ integrity when you don’t conform to the basic rules of scholarship,” Virginia Tech plagiarism expert Skip Garner says. Led by George Mason University statistician Edward Wegman, the 2006 report criticized the statistics and scholarship of scientists who found the last century the warmest in 1,000 years. “The report was integral to congressional hearings about climate scientists,” says Aaron Huertas of the Union of Concerned Scientists in Washington, D.C. “And it preceded a lot of conspiratorial thinking polluting the public debate today about climate scientists.” But in March, climate scientist Raymond Bradley of the University of Massachusetts asked GMU, based in Fairfax, Va., to investigate “clear plagiarism” of one of his textbooks. Bradley says he learned of the copying from a year-long analysis of the Wegman report made by retired computer scientist John Mashey of Portola Valley, Calif. Mashey’s analysis concludes that 35 of the report’s 91 pages “are mostly plagiarized text, but often injected with errors, bias and changes of meaning.” Copying others’ text or ideas without crediting them violates universities’ standards, according to Liz Wager of the London-based Committee on Publication Ethics. “The matter is under investigation,” says GMU spokesman Dan Walsch by e-mail. In a phone interview, Wegman said he could not comment at the university’s request. In an earlier e-mail Wegman sent to Joseph Kunc of the University of Southern California, however, he called the plagiarism charges “wild conclusions that have nothing to do with reality.” The plagiarism experts queried by USA TODAY disagree after viewing the Wegman report: • “Actually fairly shocking,” says Cornell physicist Paul Ginsparg by e-mail. “My own preliminary appraisal would be ‘guilty as charged.’ “ •”If I was a peer reviewer of this report and I was to observe the paragraphs they have taken, then I would be obligated to report them,” says Garner of Virginia Tech, who heads a copying detection effort. “There are a lot of things in the report that rise to the level of inappropriate.” •”The plagiarism is fairly obvious when you compare things side-by-side,” says Ohio State’s Robert Coleman, who chairs OSU’s misconduct committee. The report was requested in 2005 by Rep. Joe Barton, R-Texas, then the head of the House energy committee. Barton cited the report in an October letter to The Washington Post when he wrote that Penn State climate scientist Michael Mann’s work was “rooted in fundamental errors of methodology that had been cemented in place as ‘consensus’ by a closed network of friends.” The Wegman report criticized 1998 and 1999 reports led by Mann (Bradley was a co-author) that calculated global temperatures over the last dozen centuries. It also contained an analysis of Mann’s co-authors that appears partly cribbed from Wikipedia, Garner says…. A 2006 report by the National Research Council (NRC), which examines scientific disputes under a congressional charter, largely validated Mann, Bradley and the other climate scientists, according to Texas A&M’s Gerald North, the panel’s head. The NRC report found the Wegman report’s criticism of the type of statistics used in 1998 and 1999 papers reasonable but beside the point, as many subsequent studies had reproduced their finding that the 20th century was likely the warmest one in centuries. Indeed, the Nature article on the report was headlined, “Academy affirms hockey-stick graph.” The Wegman report called for improved “sharing of research materials, data and results” from scientists. But in response to a request for materials related to the report, GMU said it “does not have access to the information.” Separately in that response, Wegman said his “email was downloaded to my notebook computer and was erased from the GMU mail server,” and he would not disclose any report communications or materials because the “work was done offsite,” aside from one meeting with Spencer…. cont added by: JanforGore
