In a major development for polar science, the Antarctic Ice Sheet (AIS) experienced a stunning mass gain of over 100 billion tons in a single year, a sharp reversal from decades of steady decline. Recent satellite data from missions like NASA’s GRACE and GRACE-FO revealed that between 2021 and 2023, the continent gained an average of 108 to 119 gigatons of ice annually. This rare growth was significant enough to temporarily slow global sea level rise by approximately 0.3 millimeters per year dur
