Antarctic Glacier's Alarming Speed Doubling and Ice Loss Revealed

The Cadman Glacier in Antarctica has experienced a significant increase in melting speed, nearly doubling its retreat between 2018 and 2019 after decades of little change. Researchers found that warming oceans were the main driver behind the accelerated melting, with a positive temperature anomaly allowing warm water to reach the glacier. The retreat of glaciers in the western Antarctic Peninsula, including the Cadman Glacier, is destabilizing the Antarctic Ice Sheet, contributing to potential future sea level rise. While the Cadman Glacier alone won't have a significant impact on sea level rise, it serves as an indicator of the larger decay of the Antarctic ice sheet due to rising water temperatures.
