,From The Guardian Monday 1 February 2010 - Fred Pearce
E-mails leaked by hackers from the University of East Anglia's climatic research unit (CRU) turned up additional concerns. A study by the London paper, The Guardian, found serious flaws in measurements from Chinese weather stations, noting that documents from them could not be produced.
The e-mails revealed that Chinese monitoring stations were moved several times, making their data unreliable. This data was cited by the U.N.'s Intergovernmental Panel on Climate Change to prove rapid global warming in the last few decades.
Further, according to The Guardian, CRU chief scientist Phil Jones withheld information requested under freedom of information laws. Of 105 freedom of information requests concerning the climatic research unit (CRU), only 10 had been released in full.
There had been some question concerning the work of Jones's collaborator, Wei-Chyung Wang of the University at Albany-SUNY. Allegations are that he committed fraud in his research cited by the Fourth Assessment Report of the IPCC (2007) on
“urban heat islands” (a critical issue). Douglas J. Keenan has detailed it in a paper - THE FRAUD ALLEGATION AGAINST SOME CLIMATIC RESEARCH OF WEI-CHYUNG WANG
Wang was cleared of scientific fraud by his university, but new information brought on by the emails indicates at least one senior colleague had serious concerns about the affair and told Jones that he feared that Wang had "screwed up."
"The former director of the unit, Tom Wigley, harboured grave doubts about the cover-up of the shortcomings in Jones and Wang's work. Wigley was in charge of CRU when the original paper was published. "Were you taking W-CW [Wang] on trust?" he asked Jones. He continued: "Why, why, why did you and W-CW not simply say this right at the start?"
Unfortunately, it now seems that documents Wang claimed would exonerate him and Jones do not exist.
