ILULISSAT ISFJORD, GREENLAND
June 7, 2007
Ground Zero of the climate change story: the calving face of the Ilulissat Glacier. This four-mile-wide (6.4 km.) wall of ice discharges more ice into the global ocean than any other glacier in the Northern Hemisphere. During the past ten years, its flow rate has doubled, apparently in response to warming temperatures and more meltwater lubrication at its base. It now sends 11 cubic miles of ice out to sea.
