Arctic Sea Ice Reaches Another Record Low
Every year, Arctic sea ice grows and extends through the winter. On March 7, 2017, Arctic sea ice reached its annual maximum extent, setting a new record low. A low September minimum extent and a warm winter contributed to the low Arctic ice maximum. On February 13, the Arctic and Antarctic sea ice combined extent also set a new record. Globally, there was less sea ice than at any time since satellites began continuously tracking in 1979.
