New Frontiers Seminar Series - Professor Richard Peltier

New Frontiers Seminar “Rapid Climate Change and the Oceans” by Professor Richard Peltier.

All are welcome to attend the New Frontiers Seminar given by Professor Richard Peltier entitled Rapid Climate Change and the Oceans.

Founder of U of T’s Centre for Global Change Science and distinguished member of the Department of Physics (St. George campus), Peltier is known worldwide for his research on global climate change. Using sophisticated mathematical concepts, he has developed powerful models to depict what happened to our climate over the past 750 million years and what is likely to happen in the future—if human behaviour does not change. His models of ice-age climate variability are considered the gold standard for research on climate change.

Professor Peltier's research accomplishments have been recognized multiple times. He was the winner of the 2002 Vetlesen Prize (often called the Nobel of Earth Sciences), the 2010 Bower Prize,  the 2011 Herzberg Gold Medal from the Natural Sciences and Engineering Council and a 2013 Killam Prize.

Abstract: The Dansgaard-Oeschger oscillations that are such a prevalent component of climate variability during marine oxygen isotopic stage 3 (MIOS 3) of the most recent Late Quaternary glacial cycle have never been explained although there are many competing hypotheses. The controversy continues, in no small part because the oscillation has never been shown to occur in a modern coupled climate model. I will demonstrate that this circumstance no longer exists and discuss the physical mechanism we have discovered that underlies the process. It would appear to lie at the heart of the origins of the rapid climate changes that occurred during glacial conditions.


The New Frontier Seminar Series is hosted by the Graduate Students' Association at Scarborough (GSAS) and sponsored by the Office of the Vice-Principal Research. The series showcases cutting edge research from the University of Toronto Scarborough, while highlighting new discoveries from leading researchers in North America.
