No ‘Research Misconduct’ by Climate-Change Scientist, U.S. Says

Michael Mann, a Pennsylvania researcher who’s been a target of climate-change skeptics, was cleared of wrongdoing by U.S. investigators in the flap surrounding e-mails hacked from a U.K. university.

Finding no “evidence of research misconduct,” the Arlington, Virginia-based National Science Foundation closed its inquiry into Mann, according to an Aug. 15 report from the inspector general for the U.S. agency. Pennsylvania State University, where Mann is a professor of meteorology, exonerated him in February of suppressing or falsifying data, deleting e-mails and misusing privileged information.
