0

Sea ice in the Arctic appears to have hit its annual maximum extent after growing through the fall and winter.

The 2021 wintertime extent reached on March 21 ties with 2007’s as the seventh-smallest extent of winter sea ice in the satellite record, according to scientists at the NASA-supported National Snow and Ice Data Center and NASA.

This year’s maximum extent peaked at 5.70 million square miles (14.77 million square kilometers) and is 340,000 square miles (880,000 square kilometers) below the 1981 to 2010 average maximum – equivalent to missing an area of ice larger than the state of Texas and Florida combined.
