Michael E. Mann (born 28 December 1965) is an American climatologist, and author of more than 80 peer-reviewed journal publications. He has attained public prominence 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 the shape of the graph. The graph received both praise and criticism after its publication in an Intergovernmental Panel on Climate Change (IPCC) report.

The hockey stick has since been proven to be a Fraud

In August 2005 he was appointed Associate Professor at Pennsylvania State University, in the Department of Meteorology and Earth and Environmental Systems Institute, and Director of the university's interdepartmental Earth System Science Center. He previously taught at the University of Virginia, in the Department of Environmental Sciences (1999 - 2005).

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 controversial paleoclimate 'hockey stick' reconstructions of the past several millennia from tree ring, ice core, coral and other data. See temperature record of the past 1000 years for more details and dispute. 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.[1]

In November 2009, Mann's correspondence with fellow climate researchers was among that released in the Climatic Research Unit e-mail hacking incident, which stoked public debate about global warming[2]. Mann published an editorial in The Washington Post[3] on December 18, asserting that the hacked e-mails "do not undermine the scientific case that human-caused climate change is real."
