瑞典乌普萨拉大学参与的国际研究团队公布了一项长期冰盖监测成果。该研究基于27项卫星任务数据和区域气候模型，发现1979年至2023年间格陵兰和南极冰盖共损失约11.3万亿吨冰1，这一冰量损失已导致全球平均海平面上升超过3厘米1。
冰盖冰量流失速度在过去数十年间明显加快。格陵兰冰盖的年均冰量损失从20世纪80年代的约600亿吨增至2010年代的约2640亿吨1，南极冰盖的年均冰量损失则从20世纪80年代的约480亿吨上升至2010年代的约2020亿吨1。研究指出，连续多年偏高的夏季气温造成了大范围冰面融化1。
近年来两大冰盖的冰量损失速度有所减缓，但研究人员强调这一现象不能被解读为长期趋势的逆转1。该研究成果已发表在学术期刊《科学数据》上1。
An international research team involving Sweden's Uppsala University has documented massive ice loss across the world's two largest ice sheets over the past four decades. 1 Between 1979 and 2023, the Greenland and Antarctic ice sheets combined lost approximately 11.3 trillion tons of ice, contributing to a global mean sea level rise exceeding 3 centimeters. 1 The study, which drew on data from 27 satellite missions encompassing 42 independent estimates, was published in the academic journal Scientific Data. 1
The research reveals a striking acceleration in ice loss rates over the period studied. 1 Greenland's ice sheet increased its annual ice loss from approximately 60 billion tons during the 1980s to roughly 264 billion tons in the 2010s, while Antarctica's corresponding figures rose from 48 billion tons to 202 billion tons over the same intervals. 1 Extended periods of unusually high summer temperatures have triggered widespread surface melting across both ice sheets. 1 Although ice loss has moderated in recent years, researchers caution against interpreting this slowdown as a reversal of the long-term trend. 1
