Arctic Tipping Point: A North Pole Without Ice

EarthzineSeptember 3, 2012Climate, Earth Observation

This NASA map, based on satellite data, shows the new record-low summer sea ice extent of 1.58 million square miles in the Arctic Ocean, as recorded on August 26. The amount of sea ice covering the Arctic Ocean at the end of summer is now 45 percent lower than the average from 1979 to 2000. The black dot represents the region surrounding the North Pole.
