Looks like Michael Mann and the climatology community at Penn State got an all (a mostly, largely, nearly, ninety-nine percent, practically) clear from the panel investigating them. [Props to JimR for keeping me accurate.] Read the report from Penn State here.
Actually, if you’re not associated with a university that pays a university subscription to climate wire, you may not be able to read that. Even still, I’m fairly sure I can quote this without copyright infringement:
An internal inquiry has largely cleared Pennsylvania State University climatologist Michael Mann of scientific misconduct, but the university said yesterday that it will continue to probe whether the researcher undermined public trust in science.
