新研究預計海平面下世紀將大幅升高
A new study shows sea levels will rise higher than previously believed by the end of this century, due to rapidly melting ice from Antarctica.
一項新研究顯示，由於南極冰川迅速融化，海平面到本世紀末的上升幅度將超過以往的預測。
Using sophisticated computer models, American researchers Rob deConto and David Pollard found that at the current rate of greenhouse gas emissions, the world's oceans would rise by close to two meters by the year 2100, and as much as 15 meters by the year 2500.
美國科學家德孔託和波拉德利用複雜的電腦模型發現，按照目前溫室氣體的排放量估算，世界海平面到2100年將上升將近兩米，到2500年將上升多達15米。
By contrast, the latest report from the United Nations' Intergovernmental Panel on Climate Change had predicted sea levels would rise just under one meter by 2100, mainly from warming seas, melting glaciers and the Greenland ice shelf.
與此形成對照的是，聯合國的政府間氣候變化專門委員會曾預測，世界海平面到2100年將上升不到一米，其主要因素包括海水變暖以及冰山和格陵蘭冰架融化。
If DeConto and Pollard's predictions, published Wednesday in the journal Nature are correct, many coastal areas, such as south Florida and New Orleans in the United States, the city of Shanghai, and Bangladesh could be seriously threatened by rising sea levels.
德孔託和波拉德的研究報告發表在《自然》雜誌上。如果他們的預測準確，很多沿海地區都可能受到海平面升高的嚴重威脅，其中包括美國的佛羅里達南部、新奧爾良、還有上海和孟加拉國。
