Michael E. Mann - Get the anti-science bent out of politics As a scientist, I shouldn't have a stake in the upcoming midterm elections, but unfortunately, it seems that I -- and indeed all my fellow climate scientists -- do. Rep. Darrell Issa (R-Calif.) has threatened that, if he becomes chairman of the House Committee on Oversight and Government Reform, he will launch what would be a hostile investigation of climate science. The focus would be on e-mails stolen from scientists at the University of East Anglia in Britain last fall that climate-change deniers have falsely claimed demonstrate wrongdoing by scientists, including me. Rep. James Sensenbrenner (R-Wis.) may do the same if he takes over a committee on climate change and energy security. My employer, Penn State University, exonerated me after a thorough investigation of my e-mails in the East Anglia archive. Five independent investigations in Britain and the United States, and a thorough recent review by the Environmental Protection Agency, also have cleared the scientists of accusations of impropriety. Nonetheless, Virginia Attorney General Ken Cuccinelli is investigating my previous employer, the University of Virginia, based on the stolen e-mails. A judge rejected his initial subpoena, finding that Cuccinelli had failed to provide objective evidence of wrongdoing. Undeterred, Cuccinelli appealed the decision to the Virginia Supreme Court and this week issued a new civil subpoena. What could Issa, Sensenbrenner and Cuccinelli possibly think they might uncover now, a year after the e-mails were published? The truth is that they don't expect to uncover anything. Instead, they want to continue a 20-year assault on climate research, questioning basic science and promoting doubt where there is none.
