The 2018 extent reached 5.59 million square miles, only about 23,000 square miles larger than the lowest maximum on record, in 2017.

This continues a trend of shrinking sea ice, with the four lowest Arctic sea ice maximum extents on record in the last four years. Dr. Claire Parkinson explains how and why NASA studies Arctic sea ice.
