PEI Faculty Seminar: 3 Million Years of Global Climate Change Captured in Ice Cores
Michael Bender, Professor of Geosciences, Emeritus, and Senior Geoscientist, will present, “3 Million Years of Global Climate Change Captured in Ice Cores,” at 12:30 p.m. Tuesday, April 3, in Guyot Hall, Room 10. Lunch will be served at noon in the Guyot Atrium. Bender, who is PEI associated faculty, is the third speaker in the Spring 2018 PEI Faculty Seminar Series.
Ice cores collected by drilling through the Antarctic and Greenland ice sheets preserve fossil air and chemical properties that reflect past climates. These records, which extend back 800,000 years, show that Antarctic temperatures and global climate were closely linked to atmospheric CO2 concentration. Recently, we successfully retrieved from Antarctica “chunks” of ice more than 2 million years old. These samples allow us to begin examining connections between climate and greenhouse gases at the time when glacial periods became increasingly intense, leading to the massive ice sheets associated with glacial periods of the past 800,000 years.
