Science Panel Backs Study on Warming ClimateI especially like that part about "disputes over details" between the "scientists" who conducted the survey and those scientists who believe the "details" matter.
By Andrew C. Revkin, The New York Times
WASHINGTON, June 22 — A controversial paper asserting that recent warming in the Northern Hemisphere was probably unrivaled for 1,000 years was endorsed today, with a few reservations, by a panel convened by the nation's pre-eminent scientific body.
The panel said that a statistical method used in the 1999 study was not the best and that some uncertainties in the work "have been underestimated," and it particularly challenged the authors' conclusion that the decade of the 1990's was probably the warmest in a millennium.
But in a 155-page report, the 12-member panel convened by the National Academies said "an array of evidence" supported the main thrust of the paper. Disputes over details, it said, reflected the normal intellectual clash that takes place as science tests new approaches to old questions. (link)
This isn't a scientific study. It's a guess.
