Southern Ice Sheet Growth Continues to Puzzle Climate Scientists

Record-Breaking Ice Mass Gain Defies Decades of Loss
The Antarctic Ice Sheet has done something that genuinely shocked climate scientists around the world. Between 2021 and 2023, the AIS experienced a record-breaking increase in overall mass, marking the first time in decades that Antarctica gained mass, reversing previous loss trends. This wasn’t just a minor fluctuation – the ice sheet gained approximately 108 gigatons per year during this period, completely reversing what scientists had observed for the previous two decades.
The magnitude of this reversal is staggering when you consider the numbers. From 2002-2010, Antarctica experienced moderate ice loss at -73.79±56.27 gigatonnes per year, which nearly doubled to -142.06±56.12 gigatonnes per year during 2011-2020. Then came the complete turnaround that has left researchers scrambling to understand what’s happening. That growth was enough to temporarily offset global sea level rise by about 0.3 millimeters per year during the same period.
