Earth’s Changing Climate
The New Face of the Arctic
by U-M Professor Emeritus Dr. Henry Pollack
Event Date
Thursday, February 14, 2013: 3:30 to 4:30 PM EST
Abstract
The Arctic region is experiencing climate change at a pace far faster than the rest of the globe, due to climatological factors that cause what is known as polar amplification. The summer sea-ice is in rapid decline, the winter sea-ice is also diminishing, the surrounding permafrost is thawing, methane is being released to the atmosphere, and Greenland is melting over much of its surface and shedding ice to the sea at an accelerating pace. Such dramatic changes are spurring geological and biological resource exploitation, maritime transportation, tourism, territorial disputes, and military activity.
