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.
Henry Pollack is an advisor to the National Science Foundation and a member of the Intergovernmental Panel on Climate Change, which shared the 2007 Nobel Peace Prize with Al Gore. He has conducted scientific research on all seven continents and has traveled regularly to Antarctica. Pollack is the author of A World Without Ice, which provides an analysis of climate change science. He also wrote Uncertain Science … Uncertain World.
