MICHAEL E MANN  Climat-ologist and geophysicist Mann was lead author of a paper produced in 1999 with co-authors Raymond S. Bradley and Malcolm K. Hughes, Mann using advanced statistical techniques to find regional variations in a hemispherical climate reconstruction to produce a reconstruction over the past 1,000 years which was dubbed the “hockey stick graph” because of its shape. He was and is, of course, viciously attacked by people who are paid by fossil fuel companies to create doubt about climate change. But Mann has been courageous and unrelenting and he was acknowledged by the Intergovernmental Panel on Climate Change as one of the key authors, contributing to the award of the 2007 Nobel Peace Prize, which was won jointly by the IPCC and Al Gore.
