You'll want to consider this article by the American Thinker (carefully):
The CRU emails have revealed how the normal conventions of the peer review process appear to have been compromised by a team* of global warming scientists, with the willing cooperation of the editor of the International Journal of Climatology (IJC), Glenn McGregor. The team spent nearly a year preparing and publishing a paper that attempted to rebut a previously published paper in IJC by Douglass, Christy, Pearson and Singer (DCPS). The DCPS paper, reviewed and accepted in the traditional manner, had shown that the IPCC models that predicted significant "global warming" in fact largely disagreed with the observational data.
We will let the reader judge whether this team effort, revealed in dozens of emails and taking nearly a year, involves inappropriate behavior including (a) unusual cooperation between authors and editor, (b) misstatement of known facts, (c) character assassination, (d) avoidance of traditional scientific give-and-take, (e) using confidential information, (f) misrepresentation (or misunderstanding) of the scientific question posed by DCPS, (g) withholding data, and more.
Read the rest here. At a minimum, the CRU emails seem to reveal a group of individuals so driven by their ideology that the intellectual honesty of the publications require scrutiny and review.
