Michael E. Mann is an American climatologist, author of more than 80 peer-reviewed journal publications, most notably a number of articles on paleoclimate and as one of the originators of a graph of temperature trends dubbed the "hockey stick graph" for the shape of the graph.See the video.
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 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). 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 several 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. Mann is one of several climate scientists who contribute to the RealClimate blog.
He is best known for his paleoclimate 'hockey stick' reconstructions of climatic fluctuations over the past several millennia, based on evidence from tree rings, ice cores, corals and other physical proxies. Such reconstructions have been the subject of some controversy; see temperature record of the past 1000 years for an overview. Mann's recent work has been on modelling El Niño, and he has said that "we are already committed to 50 to 100 years of global warming and several centuries of sea level rise" and that reduction in fossil fuel emissions is required to slow the process down to a level that can be coped with.
In November 2009, Mann's correspondence with fellow climate researchers was among that released in the Climatic Research Unit hacking incident. In an interview broadcast by the BBC, Mann commented that the "emails are genuine and have been misrepresented, cherry-picked, mined for single words and phrases that can be completely twisted to imply the opposite of what was actually being said..." He wrote in The Washington Post that the hacked e-mails "do not undermine the scientific case that human-caused climate change is real."
