The e-mails, attributed to prominent American and British climate researchers, include discussions of scientific data and whether it should be released, exchanges about how best to combat the arguments of skeptics, and casual comments — in some cases derisive — about specific people known for their skeptical views. Drafts of scientific papers and a photo collage that portrays climate skeptics on an ice floe were also among the hacked data, some of which dates back 13 years. . . .
In several e-mail exchanges, Kevin Trenberth, a climatologist at the National Center for Atmospheric Research, and other scientists discussed whether a string of recent years of relatively stable temperatures undermined scientific models that predict long-term warming.
“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,” Dr. Trenberth wrote.
Other scientists went on to rebut him, saying that the fluctuations were not inconsistent with a continuing warming trend.
Dr. Trenberth said Friday that he was appalled at the release of the e-mails, which he said were private discussions. . . . .
At first, said Dr. Michaels, the climatologist who has faulted some of the science undergirding the global warming consensus, his instinct was to ignore the correspondence as “just the way scientists talk.”
But on Friday, he said, after reading more deeply, he felt that some exchanges reflected a concerted effort to block the release of data for independent review.
