Antarctic mass loss slowdown (2016-2020)
After losing mass at a near-linear rate since about 2000, the Antarctic Ice Sheet's net loss began slowing in 2016, and satellite gravimetry showed net mass gains from 2020 even as discharge from outlet glaciers accelerated.
Slowed Antarctica's contribution to sea level rise for several years.
Showed that accumulation-driven pauses can mask ongoing dynamic ice loss from fast-flowing glaciers.
The 2021-2023 gain is a sharper, bigger version of the same phenomenon: a temporary accumulation anomaly, not a change in the ice sheet's trajectory.
