Antarctica’s ice loss is locked in, and extra snowfall won’t save it – that’s bad news for low‑lying coastal areas elsewhere

The Antarctic ice sheet’s future depends how a chain of events plays out. A new study finds the evidence points in one direction.

新研究用機器學習模型檢驗數十萬種未來情景並用衛星觀測篩選，發現即使全球變暖控制在1.5°C，南極洲本世紀仍將淨損失冰量。這意味著南極對海平面上升的貢獻難以避免，但減少排放仍能顯著減緩損失。
