Michael E. Mann (born 28 December 1965) is an American climatologist, and author of numerous peer-reviewed journal publications. He is best known as lead author of a number of articles on paleoclimate and as one of the originators of a graph of temperature trends dubbed the "hockey stick graph" for its hockey stick-like shape. The graph was highlighted in an Intergovernmental Panel on Climate Change (IPCC) report, receiving both praise and criticism, and has been the subject of a long-running controversy.
Career and awards
From 1999 to 2005 Mann taught at the University of Virginia, in the Department of Environmental Sciences. In 2009 he was promoted to professor at Pennsylvania State University, in the Department of Meteorology and Earth and Environmental Systems Institute and since 2005 has been Director of the university's interdepartmental Earth System Science Center.
He has been organizing committee chair for the National Academy of Sciences 'Frontiers of Science' and has served as a committee member or advisor for other National Academy of Sciences panels. He served as editor for the Journal of Climate and has been a member of numerous international and U.S. scientific advisory panels and steering groups.
Mann has been the recipient of numerous fellowships and prizes, including selection as one of the 50 leading visionaries in Science and Technology by Scientific American, the outstanding scientific publication award of the National Oceanic and Atmospheric Administration (NOAA), and recognition by the Institute for Scientific Information (ISI) for notable citation of his refereed scientific research. He is one of several climate scientists who contribute to the award-winning RealClimate blog.
He is the lead author or co-author of over 90 scientific publications, the majority of which have appeared in leading peer-reviewed scientific journals. He was a Lead Author on the “Observed Climate Variability and Change” chapter of the Intergovernmental Panel on Climate Change (IPCC) Third Scientific Assessment Report (2001).
Climate change controversies
Mann is best known for his work on the temperature record of the past 1000 years, which has involved reconstructing climatic fluctuations over the past several millennia, based on evidence from tree rings, ice cores, corals and other physical proxies. This work has been the subject of a long-running controversy focusing on a graph dubbed the "hockey stick" published in a 1998 study co-authored with Malcolm K. Hughes and Raymond S. Bradley. The graph has been a focus of attacks from those opposed to the scientific consensus on climate change. The conclusions represented by the graph were nonetheless endorsed by the US National Academy of Sciences in a 2006 report. Mann has noted that his findings have been "independently verified by independent teams using alternative methods and alternative data sources". More than a dozen subsequent scientific papers, using various statistical techniques and combinations of proxy records, produced reconstructions broadly similar to the original "hockey stick" graph. Almost all of them supported the conclusion that the warmest decade in the last thousand years was probably that at the end of the 20th century.
In November 2009, some of Mann's correspondence with fellow climate researchers was among the hacked e-mails at the centre of the Climatic Research Unit email controversy. Mann rejected allegations of wrongdoing, commenting that the e-mails had been "misrepresented, cherry-picked ... completely twisted to imply the opposite of what was actually being said". Two reviews by Pennsylvania State University in 2010 cleared Mann of any research misconduct, stating that "there is no substance" to the allegations against him, though criticizing him for sharing unpublished manuscripts with third parties. Mann welcomed these findings, commenting that they "should finally put to rest the baseless allegations against me and my research."
Virginia Attorney General Ken Cuccinelli began an investigation of Mann in April 2010 focusing on his work at the University of Virginia between 1999-2005. He served a civil investigative demand on the university seeking a broad range of documents, alleging that the hacked e-mails indicated that fraud may have been committed in relation to the award of four grants. The allegation was rejected by Mann and was strongly criticized by scientific and civil liberties organizations and hundreds of individual scientists as being unfounded, entirely unwarranted and an attack on academic freedom. The university filed suit to overturn the demand, citing protection under the First Amendment and charging that Cuccinelli was exceeding his authority.
