AI 与消失的湖泊:科学家近实时绘制北极永久冻土融化图
科学家利用 AI 分析卫星影像,通过识别热喀斯特池塘和突然消失的湖泊来近实时追踪北极永久冻土融化。Permafrost Discovery Gateway 团队已绘制并持续监测北极超过 400 万个湖泊,其中包括阿拉斯加苔原上的 7000 万个热喀斯特池塘。在 2026 年 6 月和 7 月,该团队又发现约 30 个湖泊受到排水影响。
lity of the Arctic’s version of the sinkhole. There is no way to directly measure permafrost without digging into it , but there are signs to watch for. When ice-rich permafrost thaws, the ground surface subsides, creating what are known as thermokarst ponds – depressions that fill with water. Much of the Arctic has become dotted by ponds and lakes that formed this way, as temperatures there rise at two to three times the global average rate. Thermokarst ponds like these dot the landscape on the
