新研究警告:到2100年气候变化可能导致海平面上升2米

据外媒报道,一项新研究警告称,如果允许气候变化以目前的速度继续下去,到2100年海平面可能会上升6.5英尺(约2米)。警告来自20多位冰盖专家,他们认为格陵兰岛和南极冰盖融化充满不确定性。对于世界上许多沿海城市来说,海平面上升那么多将是灾难性的。

新数字基于一种称为结构化专家判断(SEJ)的技术,这是一个由22名冰盖专家组成的科学家团队提出的。基于这些专家提供的合理的未来海平面上升,由布里斯托大学领导的团队确定到2100年海平面可能上升2米/6.5英尺是“小而有意义的概率”事件。这一估计是基于人们没有采取任何措施来应对全球变暖的情况。

研究人员假设,最糟糕的情况是将有大约179万平方公里的土地被淹没,包括纽约和迈阿密等许多主要城市的洪水 - 多达1.87亿人可能被迫搬迁。同样,洪水将淹没一些被认为对粮食生产至关重要的地区。

这些信息在区域和全球范围内的未来决策中发挥着重要作用。虽然这是一项极端估计,预计实际海平面上升不会那么显著,但研究人员指出,极端潜力不应该被忽视。
