“We were not asked to assess the reality of global warming and indeed this is not an area of our expertise. We do not assume any position with respect to global warming except to note in our report that the instrumented record of global average temperature has risen since 1850 according to the MBH 99 chart by about 1.2º centigrade.”11“Report on the ‘Hockey Stick’ Global Climate Reconstruction” (PDF).

“Overall, our committee believes that Dr. Mann’s assessments that the decade of the 1990s was the hottest decade of the millennium and that 1998 was the hottest year of the millennium cannot be supported by his analysis.”13“Report Raises New Questions About Climate Change Assessments” (PDF).

The Wegman Report, officially titled the “Ad Hoc Committee Report On the ‘Hockey Stick’ Global Climate Reconstruction” was released.

It was commissioned by Congress as an investigation into the “hockey stick” graph published by Michael Mann and used by the Intergovernmental Panel on Climate Change (IPCC) prominently to illustrate the reality of climate change. The Wegman report was highly critical of Mann’s graph.

Wegman was later accused of plagiarizing sections of the report, largely from one of the graph’s original authors, Raymond Brandley.

Although the George Mason University is investigating the report, they have not yet acted on the charges. Nature recently questioned why George Mason University has taken over fourteen months in their review.

A report by John Mashey found Wegman’s report to be guilty of falsifications, misrepresentation and fabrications that could give rise to a charge of academic misconduct. The Wegman report was initially accepted in 2008 in the journal of Computational Data and Statistics Analysis (CSDA). Following complaints to the CSDA, it was later retracted due to possible plagiarism from Wikipedia and textbooks.16John Mashey. “John Mashey on Strange Scholarship in the Wegman Report,” Deep Climate, September 26, 2010.

Deep Climate summarized in 2010:17Wegman and Said on social networks: More dubious scholarship,” Deep Climate, April 22, 2010. Archived June 16, 2020. Archive URL: https://archive.vn/ocqCB

“In both the original Wegman report and a subsequent follow-up paper by Yasmin Said, Wegman and two others, the background sections on social network research show clear and compelling instances of apparent plagiarism. The three main sources, used almost verbatim and without attribution, have now been identified. These include a Wikipedia article and a classic sociology text book by Wasserman and Faust. But the papers rely even more on the third source, a hands-on text book that explores social network concepts via the Pajek analysis software package – the same tool used by the Wegman team to analyze ‘hockey stick’ author Michael Mann’s co-author network.”

Further analysis by Mashey, referencing reporting by Dan Vergano in USA Today, also notes a “serious breach of peer review” when Wegman sent his article to Editor-in-Chief Stanley Azen, a long-time close friend and colleague.18John R Mashey. “Strange Tales and Emails: Said, Wegman, Sharabati, Rigsby (2008)” (PDF), DeSmog, May 26, 2011.

“[Azen] did only a cursory personal review, without relevant SNA expertise. He accepted it with no revision in 6 days, quite unusual treatment, especially of a poor article trying to cast doubts on the quality of peer review in climate science, with no evidence of wrongdoing,” Mashey commented.20John R Mashey. “Strange Tales and Emails: Said, Wegman, Sharabati, Rigsby (2008)” (PDF), DeSmog, May 26, 2011.
