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.

新研究用机器学习模型检验数十万种未来情景并用卫星观测筛选，发现即使全球变暖控制在1.5°C，南极洲本世纪仍将净损失冰量。这意味着南极对海平面上升的贡献难以避免，但减少排放仍能显著减缓损失。
