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. Anders A. Bjork, Natural History Museum of Denmark
FUTURE LOSS: Massive icebergs prepare to calve from the Upernavik Ice Stream. Niels J. Korsgaard, Natural History Museum of Denmark
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. Niels J. Korsgaard, Natural History Museum of Denmark
ICE STREAM: Fast-flowing ice reveals itself with crevasses and other wrinkles in the sheet, as compared with the smooth, slower-moving surrounding ice. Niels J. Korsgaard, Natural History Museum of Denmark

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. Niels J. Korsgaard, Natural History Museum of Denmark
MELTDOWN: In one week in mid-July this year nearly the entire surface of the Greenland ice sheet melted for a few days. NASA
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... Niels J. Korsgaard, Natural History Museum of Denmark
