William Richard Peltier, Ph.D., D.Sc. (hc)  (born 1943), is a university professor of physics at the University of Toronto. He is director of the Centre for Global Change Science , principal investigator of the Polar Climate Stability Network , and the Scientific Director of Canada's largest supercomputer centre, SciNet . He is a fellow of the Royal Society of Canada and of the American Geophysical Union.
His research interests include: atmospheric and oceanic waves and turbulence, geophysical fluid dynamics, physics of the planetary interior, and planetary climate.
He is notable for his involvement in global glacial reconstructions from the last glacial maximum to present. He has been a major (or the primary) contributor to the global reconstructions ICE-3G, ICE-4G, ICE-5G (VM2), and the upcoming ICE-6G (VM5) (in press). These models are important for the quantification of post-glacial rebound and late Pleistocene to Holocene variations in sea level.1967 B.Sc., University of British Columbia
