Edward Wegman, a prominent statistics professor at George Mason University, is chair of the National Science Foundation's Statistical Sciences Committee and former chairman of the Committee on Applied and Theoretical Statistics of the National Academy of Sciences. He challenges the statistical methods Michael Mann used to create the famous Hockey stick graph that the UN's climate panel used to justify the Anthropogenic Global Warming Theory.
Dr. Wegman wrote:
- It is important to note the isolation of the paleoclimate community; even though they rely heavily on statistical methods they do not seem to be interacting with the statistical community. Additionally, we judge that the sharing of research materials, data and results was haphazardly and grudgingly done. In this case we judge that there was too much reliance on peer review, which was not necessarily independent. Moreover, the work has been sufficiently politicized that this community can hardly reassess their public positions without losing credibility. 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.
