A very inconvenient report on the quality of climate change statistics

The US senate house committee on energy today released a very condemning report on the statistical prowness of Mann et al.


‘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 losingcredibility.

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.’
