Satellites Show Sea Ice Sunk to Record Lows at Both Poles
On March 7, 2017, Arctic sea ice reached its annual wintertime maximum extent, according to scientists from NASA and the NASA-supported National Snow and Ice Data Center (NSIDC). The Arctic sea ice extent set a record low after a warm winter. On the opposite side of the planet, on March 3, sea ice around Antarctica hit its lowest extent ever recorded by satellites. On February 13, the combined Arctic and Antarctic sea ice numbers were at their lowest point since satellites began to continuously measure sea ice in 1979.
