Satellites Show Sea Ice in Arctic Is at a Record Low

The amount of sea ice in the Arctic has fallen to the lowest level on record, a confirmation of the drastic warming in the region and a likely harbinger of larger changes to come. Satellites tracking the extent of the sea ice found over the weekend that it covered about 1.58 million square miles, or less than 30 percent of the Arctic Ocean’s surface, scientists said. That is only slightly below the previous record low, set in 2007, but with weeks still to go in the summer melting season, it is clear that the record will be beaten by a wide margin.
The National Snow and Ice Data Center, a government-sponsored research agency in Boulder, Colo., announced the findings on Monday in collaboration with NASA. The amount of sea ice in the summer has declined more than 40 percent since satellite tracking began in the late 1970s, a trend that most scientists believe is primarily a consequence of the human release of greenhouse gases.
