到本世纪中期,冰川可能会以创纪录的速度消失,威胁到水的供应和海平面。
Glaciers could vanish at record rates by mid-century, threatening water supplies and sea levels.
根据《自然气候变化》公布的一项研究,预计全世界冰川将以加速的速度消失,根据4°C变暖假设,到20世纪50年代中期,每年有多达4 000个冰川消失。
Glaciers worldwide are projected to vanish at an accelerating rate, with up to 4,000 disappearing annually by the mid-2050s under a 4°C warming scenario, according to a study published in Nature Climate Change.
峰值损失,称为“高峰冰川灭绝”,预计2033年至2055年之间,视气候变暖程度而定。
The peak loss, termed "peak glacier extinction," is expected between 2033 and 2055, depending on warming levels.
阿尔卑斯山和安第斯山脉的小型冰川可能在20年内基本消失,而格陵兰和南极的较大冰川则将在以后下降。
Small glaciers in the Alps and Andes may largely vanish within two decades, while larger ones in Greenland and Antarctica will decline later.
即使温度在1.5摄氏度升温时,目前近一半的冰川也可能在2100年之前消失。
Even at 1.5°C warming, nearly half of current glaciers could be lost by 2100.
这项研究由苏黎世的Lander Van Tricht牵头,分析了超过20万个冰川,发现冰川损失将继续影响淡水供应、海平面、生态系统和文化遗产,突出表明迫切需要减少温室气体排放。
The research, led by ETH Zurich’s Lander Van Tricht, analyzed over 200,000 glaciers and found that glacier loss will continue to impact freshwater supplies, sea levels, ecosystems, and cultural heritage, underscoring the urgent need to reduce greenhouse gas emissions.
