Officials at a key global-warming research center in the United Kingdom have authenticated a series of e-mails and other documents apparently taken from their computer system by a hacker, but they cannot explain what scientists in internal exchanges meant by references to a "trick" that would "hide the decline" of global temperatures nor by instructions to delete contrary data.
Author James Delingpole writes in a London Telegraph column the most damaging revelations indicate climate-change scientists may have "manipulated or suppressed evidence in order to support their cause."
According to the Australian Investigate magazine, the 62-megabyte Zip file with documents, e-mail exchanges and other information from the University of East Anglia's Climate Research Unit apparently was posted by an unidentified hacker on a Russian web server.
One e-mail said: "I've just completed Mike's Nature trick of adding in the real temps to each series for the last 20 years (ie from 1981 onwards) amd (sic) from 1961 for Keith's to hide the decline."
Another expressed internal doubts: "The fact is that we can't account for the lack of warming at the moment and it is a travesty that we can't. The CERES data published in the August (Bulletin of the American Meteorological Society) 09 supplement on 2008 shows there should be even more warming: but the data are surely wrong. Our observing system is inadequate."
Further, an e-mail exchange suggested the suppression of information: "Can you delete any e-mails you may have had with Keith re (Assessment Report 4)? Keith will do likewise. He's not in at the moment – minor family crisis."
"And, perhaps most reprehensibly," Delingpole writes, "a long series of communications discussing how best to squeeze dissenting scientists out of the peer review process. How, in other words, to create a scientific climate in which anyone who disagrees with (anthropogenic global warming) can be written off as a crank, whose views do not have a scrap of authority."
