Fraser Lectureship in Northern Studies

"Measuring Past Climatic Change
from Ice Caps": Dr. Roy M. Koerner

On Wednesday, February 27th at Trent University's Wenjack Theatre, join Dr. Roy Koerner and find out what global warming could have in store for Canada at a free lecture.

Planet Earth has experienced conditions varying from "snowball earth," where everything was frozen, to "tropical earth" with trees growing as far north as Axel Heiberg. For about 90 per cent of the time over the last million years, "Canada" has been covered with 1,000 m thick ice. The last time this ice disappeared from all but the High Arctic was 11,000 years ago.

Since then, human society has developed rapidly and now we may be affecting climate. Ice core records covering the past 100,000 years can help us see where we stand now. How far will global warming go? Will it take us back 9,000 years and change our lifestyles, especially in the North?

Dr. Koerner is a graduate of Sheffield University and the London School of Economics. He is a veteran of many field seasons as a glaciologist in the polar regions since 1957.

Free and Open to the Public
Wenjack Theatre, 7 p.m.
Sponsored by two Departments of Geography at Trent University
