Guess who recently said: "We cannot make claims as to the 1990s being the warmest decade."
A New Scientist article (Feb. 12, 2005) states:
Take the grand claim made by some climate researchers that the 1990s were the warmest decade in the warmest century of the past millennium. This claim is embodied in the famous "hockey stick" curve, produced by Michael Mann of the University of Virginia in 1998, based on "proxy" records of past temperature, such as air bubbles in ice cores and growth rings in tree and coral. (see "Hotly contested") Sceptics have attacked the findings over poor methodology used, and their criticism has been confirmed by climate modellers, who have recently recognised that such proxy studies systematically underestimate past variability. As one Met Office scientist put it: "We cannot make claims as to the 1990s being the warmest decade."
I wonder who the Met Office scientist was. In an article a week earlier, New Scientist reported:
Scientists at the UK Met Office and other IPCC stalwarts were among those who reported late last year in Science that the hockey stick analysis "contains assumptions that are not permissible".
It seems to me that this is a pretty important admission. The "warmest decade" cut-phrase from MBH was how Kyoto was sold in Canada. The UK Met Office doesn’t seem to have disseminated this information with as much fanfare as the prior claim that it was the warmest decade.
Update: the article from last year mentioned above would be von Storch et al. in Science. Roger Bell suggested that the Met Office scientist in question was probably a co-author of von Storch et al. . Simon Tett of the Hadley Center was a co-author .
