NOT-SO-GLACIAL RETREAT:

This visualization of the Kong Oscar Glacier in northwestern Greenland shows the ice loss as well as the release of icebergs from the glacier.....[ More ]

FUTURE LOSS:

Massive icebergs prepare to calve from the Upernavik Ice Stream.....[ More ]

ICE HEIGHT:

The glacier pictured here rises about 40 meters above sea level. Some glaciers like it, such as Sverdrup, lost as much as 80 meters of height between 2005 and 2010.....[ More ]

ICE STREAM:

Fast-flowing ice reveals itself with crevasses and other wrinkles in the sheet, as compared with the smooth, slower-moving surrounding ice.....[ More ]

ICEBERG:

At the calving front, icebergs break off from the Upernavik Ice Stream. The overturned iceberg in the center of this picture is roughly 200 meters across.....[ More ]

MELTDOWN:

In one week in mid-July this year nearly the entire surface of the Greenland ice sheet melted for a few days.....[ More ]

OCEAN FRONT:

The Upernavik Ice Stream meets the ocean here in northwestern Greenland, calving icebergs. A plume of meltwater from beneath the glacier darkens the center of the ice sheet and reaches all the way to the sea.....[ More ]
