由创纪录的2025年温和潮湿条件驱动,北极地区河流从解冻永久冻土中变成橙色。 Arctic rivers turn orange from thawing permafrost, driven by record-warm, wet 2025 conditions.

阿拉斯加北部数以百计的北极河流正因解冻永久冻土释放铁和其他金属而变亮橙色, Hundreds of Arctic rivers in northern Alaska are turning bright orange due to thawing permafrost releasing iron and other metals, a phenomenon scientists call "rusting rivers," first observed around 2018. 诺阿发布的《2025年北极报告卡》确认,2025年是北极记录中最温暖、最湿润的年份,其升温量是全球平均水平的两倍以上。 The 2025 Arctic Report Card, released by NOAA, confirms 2025 was the warmest and wettest year on record in the Arctic, which is warming more than twice the global average. 这一迅速变暖加速了冰块流失的速度,格陵兰自1950年代以来,冰块和阿拉斯加冰川大幅缩小了1290亿吨。 This rapid warming has accelerated ice loss, with Greenland shedding 129 billion tons of ice and Alaskan glaciers thinning significantly since the 1950s. 虽然尚未确认饮用水污染,但科学家警告重金属可能会损害水生态系统。 While no drinking water contamination has been confirmed, scientists warn heavy metals could harm aquatic ecosystems. 尽管联邦气候科学受到政治压力,但该报告是由全球科学家网络独立编写的,突出表明需要持续监测。 Despite political pressures on federal climate science, the report was produced independently by a global network of scientists, underscoring the need for sustained monitoring.
