A Climate Change Corrective

Perhaps now we can put the manufactured controversy known as Climategate behind us and turn to the task of actually doing something about global warming. On Wednesday, a panel in Britain concluded that scientists whose e-mail had been hacked late last year had not, as critics alleged, distorted scientific evidence to prove that global warming was occurring and that human beings were primarily responsible.

It was the fifth such review of hundreds of e-mail exchanges among some of the world’s most prominent climatologists. Some of the e-mail messages, purloined last November, were mean-spirited, others were dismissive of contrarian views, and others revealed a timid reluctance to share data. Climate skeptics pounced on them as evidence of a conspiracy to manipulate research to support predetermined ideas about global warming.

The panel found no such conspiracy. It complained mildly about one poorly explained temperature chart discussed in the e-mail, but otherwise found no reason to dispute the scientists’ “rigor and honesty.” Two earlier panels convened by Britain’s Royal Society and the House of Commons reached essentially the same verdict. And this month, a second panel at Penn State University exonerated Michael Mann, a prominent climatologist and faculty member, of scientific wrongdoing.
