最新研究警告海平面上升幅度將高於預期
New Study Warns of Higher Sea-Level Rise Than Predicted

近期的科學研究表明，全球海平面上升的速度可能比聯合國氣候變遷專門委員會（IPCC）等主要氣候報告中預測的更快。
Recent scientific research suggests that global sea-level rise may occur faster than previously anticipated by major climate reports like those from the IPCC.
雖然這些既有模型提供了寶貴的基準，但它們本質上較為保守，且往往側重於線性預測。
While these established models provide a valuable baseline, they are inherently conservative, often focusing on linear projections.
然而，新的研究正在凸顯由極地冰層中複雜機制所引發的非線性、快速加速的風險。
New studies, however, are highlighting the risk of non-linear, rapid acceleration caused by complex mechanisms in polar ice sheets.
這些警告的核心是海洋冰層不穩定性（海洋暖水侵蝕冰川基礎）以及海洋冰崖不穩定性（可能導致結構崩塌）。
Central to these warnings is Marine Ice Sheet Instability, where warm ocean water erodes the foundation of glaciers, and Marine Ice Cliff Instability, which can lead to structural collapse.
由於地殼下沉和洋流等因素，海平面上升並非均勻變化，這對沿海地區造成了嚴重影響。
Because sea-level rise is not uniform due to factors like land subsidence and ocean currents, the implications for coastal regions are severe.
政策制定者現在受到敦促，應為高端情境做好準備，因為低估這些變化所付出的代價，可能會導致嚴重的基礎設施崩潰，以及全球沿海脆弱群體的流離失所。
Policymakers are now being urged to prepare for high-end scenarios, as the cost of underestimating these changes could lead to significant infrastructure failure and the displacement of vulnerable coastal populations worldwide.
