The Guardian reports:
Phil Jones, the beleaguered British climate scientist at the centre of the leaked emails controversy, is facing fresh claims that he sought to hide problems in key temperature data on which some of his work was based.
A Guardian investigation of thousands of emails and documents apparently hacked from the University of East Anglia’s climatic research unit has found evidence that a series of measurements from Chinese weather stations were seriously flawed and that documents relating to them could not be produced. . .
It also emerges that documents which [Jones’s collaborator, Wei-Chyung] Wang claimed would exonerate him and Jones did not exist. . .
The temperature data from the Chinese weather stations measured the warming there over the past half century and appeared in a 1990 paper in the prestigious journal Nature, which was cited by the IPCC’s latest report in 2007.
Climate change sceptics asked the UEA, via FOI requests, for location data for the 84 weather stations in eastern China, half of which were urban and half rural.
The history of where the weather stations were sited was crucial to Jones and Wang’s 1990 study, as it concluded the rising temperatures recorded in China were the result of global climate changes rather the warming effects of expanding cities.
The IPCC’s 2007 report used the study to justify the claim that “any urban-related trend” in global temperatures was small. Jones was one of two “coordinating lead authors” for the relevant chapter.
The Guardian also notes that Jones withheld the information when it was requested under the freedom of information act. Of course, that sort of behavior from Jones and his colleagues is old news now.
The Independent adds one more detail:
However, it has been reported that when climate sceptics asked for the precise locations of the 84 stations, Professor Jones at first declined to release the details. And when eventually he did release them, it was found that for the ones supposed to be in the countryside, there was no location given.
The point was to disprove the urban heat-island effect, so the non-urban measurements are key. And those are the ones that seem likely to be bogus.
