George Mason University has confirmed that it is investigating allegations of plagiarism by Professor Edward Wegman, author of the hockey stick hatchet job “Wegman Report”. According to USA Today, the investigation began earlier this year after a letter of complaint from Raymond Bradley (as in Mann, Bradley and Hughes) whose textbook Paleoclimatology: Reconstructing Climates of the Quaternary was extensively copied and crudely altered in the report to Congress. USA Today credits the investigation by Canadian blogger Deep Climate and the extensive report on errors in Wegman’s document compiled by John Mashey (covered here last month). Wegman declined to comment, but has confirmed that litigation is involved. Informed speculation suggests that this may be related to copyright issues — likely to be a problem for anyone who lifts 30% of a report from other people’s work. The story has also been picked up by the Washington Post, and Andy Revkin at Dot Earth has dubbed the affair SkepticGate. This scandal may be about to go mainstream — and not before time.
