山区变暖速度比全球平均水平快50%,对供水和生态系统构成威胁。 Mountain regions are warming 50% faster than global average, threatening water supplies and ecosystems.

全世界山区变暖速度比1950年以来全球平均速度快50%,1980年至2020年期间,高海拔每世纪加热0.21°C比低地高出0.21°C,根据《自然地球与环境评论》公布的一项研究。 Mountain regions worldwide are warming 50% faster than the global average since 1950, with high elevations heating up 0.21°C per century more than lowlands between 1980 and 2020, according to a study published in Nature Reviews Earth and Environment. 这项研究由Portsmouth大学和印度各研究所牵头,发现冰雪覆盖减少、湿度变化和气雾剂加速了积雪和干燥的速度。 The research, led by the University of Portsmouth and Indian institutions, found accelerated snow loss and drying, driven by reduced ice and snow cover, changing humidity, and aerosols. 这些变化威胁着10亿多依靠山区水源的人,增加了降水变化造成的洪水风险,迫使生态系统向上迁移,危及生物多样性。 These changes threaten over a billion people relying on mountain water sources, increase flood risks from shifting precipitation, and force ecosystems to migrate upward, endangering biodiversity. 尽管偏远地区的监测有限,但科学家们强调,迫切需要采取全球行动,应对山区气候不断加剧的影响。 Despite limited monitoring in remote areas, scientists stress urgent global action is needed to address escalating climate impacts in mountain regions.
