全球受热驱动的干旱正在上升,现在每年影响到16.7%的土地,而1980年代由于气候变化,这一比例为2.5%。 Heat-driven droughts are rising globally, now affecting 16.7% of land annually, up from 2.5% in the 1980s, due to climate change.

极端热能引发突然严重干旱的第一次热旱在全球范围迅速增加,到2023年每年影响地球土地的16.7%,比1980年代的2.5%高8倍,过去20年的增长率比1980年代高8倍。 Heat-first droughts, where extreme heat triggers sudden, severe droughts, are increasing rapidly worldwide, affecting 16.7% of Earth’s land annually by 2023—up from 2.5% in the 1980s—with the rate of increase eight times higher in the past two decades. 这些紧急干旱在南美洲、加拿大西部、阿拉斯加、美国西部以及中非和东非部分地区发展迅速,几乎没有时间准备,对农业、供水和生态系统造成重大损害。 These flash droughts, most intense in South America, western Canada, Alaska, the western U.S., and parts of central and eastern Africa, develop quickly, leaving little time for preparation and causing major harm to agriculture, water supplies, and ecosystems. 科学家们将激增与气候变化联系起来,特别是2000年左右与北极变暖、海冰丧失和雪盖不断减少有关的变化,这些变化可能改变了大气模式,加速了热与干旱之间的反馈循环。 Scientists link the surge to climate change, particularly a shift around 2000 tied to Arctic warming, sea-ice loss, and declining snow cover, which may have altered atmospheric patterns and accelerated feedback loops between heat and drought.
