Carbon steel "hockey stick" stronger than ever
The National Science Foundation (NSF) Office of the Inspector General, having conducted a thorough review and investigation into all allegations of impropriety or scientific misconduct against Penn State University Prof. Michael Mann, has dismissed all of those allegations for lack of evidence and closed the case (attached and/or here).
As reported by Joe Romm at Climate Progress, Mann has been the target of a host of allegations and attacks, many arising out of the iconic status of a graph (inset) that he created in a 1998 paper with Raymond Bradley and Malcolm Hughes, and others sourced in the emails that hackers stole in 2009 from the the Climatic Research Unit at the University of East Anglia.
As the NSF now reports, none of Mann's critics ever showed the courage or conviction of actually laying a formal complaint before Penn State, where Mann is director of the Earth System Science Center. But the allegations were so prominent in the blogosphere and in mainstream media that the university took it upon itself to conduct an investigation. The NSF then reviewed Penn State's exculpatory findings, duplicating some parts of the investigation in greater detail.
The result? No shred of evidence exists to impugn Mann's work.
