It's thinned 5 feet in just three years.
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'sand Ron Kwok of the University of Washington's Applied Physics Laboratory observed that it thinned 5 feet during that period. "We weren't really expecting to see this decline, for the ice to be this much thinner in just three short years," KacimiRelatedEach year, seasonal sea ice melts entirely in the summertime, so naturally, the ice does get thinner during this period. But the 1.5-meter loss was recorded in what scientists call multi-year ice — thicker ice that sticks around all year long and typically accumulates year-over-year. The loss represents about 16% of the multiyear ice's volume.
To determine the sea ice's thickness, researchers measure the height of the ice above sea level, taking into account the depth of the snow atop the ice, as that affects how the ice floats. For their study specifically, Kacimi and Kwok used lidar data from NASA's
