Study confirms Antarctic ice loss is inevitable this century, with high emissions driving up to 25 cm sea-level rise
A new study in Nature concludes that the Antarctic Ice Sheet is committed to mass loss by 2100, even under aggressive emissions cuts. Using machine learning to analyze ice-sheet models, researchers found that higher emissions significantly increase projected sea-level rise, potentially reaching 25.4 cm by 2100 under worst-case scenarios. The study highlights that physical assumptions in models, not just emissions, drive uncertainty, and that satellite data confirms the inevitability of ice loss.
