Satellites show Arctic sea ice is melting even faster than scientists realized

A new study based on NASA and ESA satellite data shows that Arctic sea ice is thinning at a “frightening rate.”

Measuring the ice via satellites each month from 2018 to 2021, polar scientists Sahra Kacimi of the California Institute of Technology’s Jet Propulsion Laboratory and Ron Kwok of the University of Washington’s Applied Physics Laboratory observed that it thinned 5 feet (1.5 meters) during that period.
