Michael Mann Cleared, Again
Penn State climate scientist Michael Mann, who was at the center of the 2009 controversy dubbed “Climategate,” did not engage in scientific misconduct, according to a new report by the National Science Foundation.
The controversy arose when a computer server at a British climate-research center was hacked in November 2009, and emails among climate researchers—including Mann—were published on the Internet. Climate-change skeptics claimed that the emails showed that Mann and the others had manipulated data in order to reach the conclusions that global warming is real.
Penn State investigated Mann a year ago in conjunction with the controversy and also found no evidence of research impropriety. Several other bodies, including the National Academy of Sciences, have reached the same conclusion.
Mann’s website at Penn State contains links to some of the news stories about him, including one from last month in which he talks about the attacks he’s experienced from global-warming skeptics and others.
