The Mounting Evidence and Increased Urgency: Alarm from The Cryosphere


Meanwhile, while humans keep arguing, the arctic (and the Antarctic ) keep on melting. This class will draw upon the increasing evidence coming in from various international circum-polar surveys by scientists and citizens of the artic. The class will review the concerns of scientists that changes in the arctic could lead to a modification of the thermohaline circulation system in the North Atlantic, triggering a phase of abrupt climate change in many heavily populated regions of the world.
