Current Arctic sea ice (bluish white) compared with the 1979-2010 average sea ice minimum (outlined in orange).
Researchers at the U.S. National Snow and Ice Data Center said the rate of Arctic sea ice decline is now the highest that has ever been observed. In August, the sea ice disappeared at an average rate of about 39 square miles (a hundred square kilometers)—or about twice as normal, NSIDC scientists say.
Moreover, the area of Arctic sea ice around the North Pole had shrunk to 1.58 million square miles (4.1 million square kilometers)—the smallest measurement since 1979, when satellite observations began.
