Antarctica’s Astonishing Rebound: Ice Sheet Grows! Sees ‘a record-breaking mass gain’
The Antarctic Ice Sheet (AIS) has historically lost mass, significantly contributing to sea-level rise, with intensified losses in West Antarctica and parts of East Antarctica, particularly from 2011–2020. However, between 2021 and 2023, driven by anomalous precipitation, the AIS experienced a record-breaking mass gain, even reversing trends in critical glacier basins like Totten, Moscow, Denman, and Vincennes Bay.
Mass changes across the Antarctic ice sheet have been detected using satellite gravimetry, revealing significant instabilities in major glacier basins of East Antarctica as well as across the entire ice sheet.
