Freshwater Forcing of Climate 8200 Years Ago


Date: Friday, October 10, 2003
Location: Carriage House, Quissett Campus, Woods Hole Oceanographic Insitution

As concern about the magnitude and rate of future climate change looms, it becomes increasingly important to understand the mechanisms underlying past abrupt climate change events. A cold event that occurred 8200 years ago, which affected much of the Northern Hemisphere, appears to have been triggered by the sudden release of fresh water from a huge, glacier-dammed lake that had formed during the deglaciation of North America. This abrupt climate change is probably most amenable to detailed examination because it is the most recent such event. If you are interested in this topic please join us on:
