Which of these claims has not been put forward by prominent global warming denialists ?
A Cycle analysis by a well-known astrologer proves that global temperatures will soon decline
B Data supporting global warming was faked by NASA along with the bogus moon landings
C There is no such thing as global average temperature, and therefore the whole idea is meaningless
D A voyage through the Arctic Circle by the Chinese fleet in 1421 proves that temperatures were much higher then
Answer over fold
Answer: B. Although both global warming denialists and moon landing denialists routinely accuse NASA scientists of fraud, the two groups appear not to have made common cause as yet (Please correct me if I’m wrong).
Here’s the info on the others
A. The Lavoisier Group presents a “scientific” critique of the IPCC based on the work of the late astrologer and cycle crank Theodor Landscheidt. This is the same body that claimed in a submission to Parliament (PDF here) that the Kyoto Protocol poses “the most serious challenge to our sovereignty since the Japanese Fleet entered the Coral Sea on 3 May, 1942”.
D. The best yet, tying global warming denialism to the absurd and much-demolished claims of Gavin Menzies comes from Christopher Monckton in the (UK) Telegraph, who gets an enthusiastic endorsement from Tim Blair. Tim B sees this as evidence that “the debate is not over”. His nemesis, Tim Lambert, provides a chapter and verse demolition, but the reference to Menzies is more than enough for anyone based in the real world.
While all the claims listed above are absurd, they are not lunatic fringe, at least not in the parallel universe of GW denialism. McKitrick (until recently a moderately well-known rightwing economist, but now presented as an expert on everything from physics to historical climatology) was one of the main scientific sources for the bogus House of Lords Economics Committee report and one of the “Nine Economists“, led by Nigel Lawson, who criticised the Stern Report’s first discussion paper. Their critique also relied heavily on the work of the Lavoisier Group.
