  • Thule Air Base is the U.S. military's northernmost base, located some 750 miles above the Arctic Circle. NASA's Operation IceBridge has been studying how polar ice has evolved over the past nine years, and is currently flying a set of eight-hour research flights over ice sheets and the Arctic Ocean to monitor Arctic ice loss aboard a retrofitted 1966 Lockheed P-3 aircraft. <br><br> Snow blows near Thule Air Base, March 25, 2017, in Pituffik, Greenland.

  • According to NASA scientists and the National Snow and Ice Data Center, sea ice in the Arctic appears to have reached its lowest maximum wintertime extent ever recorded on March 7, 2017. Scientists have said the Arctic has been one of the regions hardest hit by climate change. <br><br> A snowshoe hare stands near Thule Air Base, March 25, 2017, in Pituffik, Greenland.
