Thick sea ice is disappearing from the Arctic, new satellite data showPublication: NBC News Date: February 13, 2013 View Article
Thick sea ice is disappearing from a broad swath of the Arctic, according to new satellite data that confirms estimates from computer models and suggests the region may be ice free during the summers sooner rather than later.
The Arctic sea ice reached a new record minimum extent in 2012, when it covered nearly half the average area it did from 1979 to 2010. The new data show the Arctic sea ice volume in the fall, when it is at its lowest, has declined more than a third between 2003 and 2012. Ice volume in the winter has declined 9 percent.
