Asia’s mountain glaciers will lose at least a third of their mass through global warming by the century’s end, with dire consequences for millions of people who rely on them for fresh water, researchers have said.
研究人员称,到本世纪末,亚洲山区的冰川将因全球变暖而流失至少1/3,这将给数百万依赖冰川获得清洁水源的民众带来可怕后果。
This is a best-case scenario, based on the assumption that the world manages to limit average global warming to 1.5C over pre-industrial levels, a team wrote in the journal Nature.
一支研究团队在《自然》期刊上写道,这还是最好的设想,上述情况的前提是各国能够将全球温度的升高幅度控制在仅比工业化前高出1.5摄氏度。
“To meet the 1.5C target will be a task of uNPRecedented difficulty,” the researchers said, “and even then, 36% (give or take 7%) of the ice mass in the high mountains of Asia is projected to be lost” by 2100.
研究人员称:“实现这一目标将是一项前所未有的艰巨任务。而且即便如此,到2100年,亚洲高山地区的冰川预计还将流失36%(误差7%)。”
With warming of 3.5C, 4C and 6C respectively, Asian glacier losses could amount to 49%, 51% or 65% by the end of the century, according to the team’s modeling study.
根据该团队的模拟研究,当气温升高幅度分别为3.5摄氏度、4摄氏度和6摄氏度时,亚洲冰川的流失量到本世纪末将相应达到49%、51%、65%。
