Antarctic Rebound: Why The Ice Sheet’s Mass Gain Is Shocking Experts
Study reveals East Antarctica's glaciers reversed mass loss, slowing global sea level rise.

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. [emphasis, links added]
The Antarctic Ice Sheet (AIS) plays a major role in global sea-level rise. Since March 2002, the GRACE (Gravity Recovery and Climate Experiment) mission and its successor, GRACE-FO (GRACE Follow-On), have provided valuable data to monitor changes in ice mass across the AIS.
Previous studies have consistently shown a long-term trend of mass loss, particularly in West Antarctica and the Antarctic Peninsula, while glaciers in East Antarctica appeared relatively stable.
However, a recent study led by Dr. Wang and Prof. Shen at Tongji University has found a surprising shift: between 2021 and 2023, the AIS experienced a record-breaking increase in overall mass.
