NEW HAVEN, CONN.—It’s been exactly a year since “Climategate” broke, putting Penn State University researcher Michael Mann and climate scientists on both sides of the Atlantic in the hot seat after hackers released private e-mails from the Climatic Research Unit at the U.K.’s University of East Anglia.
While Mann and colleagues now face new political and legal challenges from a Republican-dominated U.S. House of Representatives and an investigation by Virginia’s attorney general, the researcher is unbowed in his personal efforts to combat climate skeptics and draw attention to the overwhelming evidence supporting human-caused climate change.
“We have to make it clear that the ice sheets are not Republican or Democrat. They don’t have a political agenda as they disappear,” warned a pugnacious Mann, in a man-the-torpedoes appearance before a crowd of journalists attending ScienceWriters2010 and the annual New Horizons in Science briefings, held this year at Yale University.
“I have no doubt we are in for a period over the next months where climate science is subject to a politically motivated inquisition,” he said, “that we haven’t seen in this country since the 1950s.”
In Mann’s case, he and others face the prospect of being called to testify at Republican-led House hearings on their climate research, as well as the Virginia attorney general’s attempt to get e-mail correspondence written while he was at the University of Virginia. Scientists, of course, are not exempt from Freedom of Information and Congressional subpoena requirements—nor should they be. But these hearings may well present an opportunity for Mann and others to reaffirm the integrity of climate science.
“They can threaten whatever they want,” Mann told MSNBC science editor Alan Boyle after his talk. “I’m quite confident to fight those sorts of witch-hunt attempts.” Boyle observed that “although Mann didn’t exactly say ‘Bring it on,” he did note that ‘those on the other side of the aisle will see this as an opportunity . We should look at this as an opportunity for offense,’ he said.”
Mann has undoubtedly grown a tougher skin following last year’s brouhaha over leaked e-mails about climate data that critics used to fuel the so-called “Climategate” scandal. The onslaught of attention raised public uncertainty about climate change and the need for tough international controls, just as world leaders were about to gather for the UN conference in Copenhagen in what turned out to be a largely failed attempt to prompt new international action.
In his talk, Mann condemned the timing of the e-mail release as an “intentional effort to distort” the science and “manufacture uncertainty and doubt.” He compared “the well-funded campaign to distract the public” to early industry efforts to undermine scientific evidence showing that smoking caused lung cancer and other health effects.
“The fringe media pounced on this,” said Mann. “This distracted the public at a critical juncture.” But he held the mainstream media liable as well. “I’d like to say the mainstream media recognized it for what it was (but) many journalists were fairly uncritical in their reporting of the controversy.” Going forward, he said, climate scientists are “reliant on the willingness of the mainstream media to serve as critical and independent arbiters.” Scientists won’t be successful in explaining their findings, he said, “unless the media is serving its role.”
Against a photo backdrop of his young daughter in front of a polar bear swimming in the waters of a local zoo, Mann ended with an emotional appeal: “I can’t imagine having to tell her when she’s grown up that the polar bear became extinct because of loss of arctic ice (and) we didn’t act soon enough to combat a problem that we knew was real but that we couldn’t convince the public of.”
