阿拉斯加永久土的融化释放碳,增加河流排水. Alaskan permafrost thawing releases carbon and boosts river runoff.

由于气温上升, 一片大面积的阿拉斯加永久土 (约相当于希腊) 正在迅速融化. A massive area of Alaskan permafrost, roughly the size of Greece, is rapidly thawing due to rising temperatures. 化会延长到夏季末, 大大增加河流的排水量并将大量古老碳释放到北极海洋. New research shows this thaw extends the season into late summer, significantly increasing river runoff and releasing vast amounts of ancient carbon into the Arctic Ocean. 科学家警告说, 这种过程可能会破坏沿海生态系统并通过危险的反循环加速全球变暖. Scientists warn this process could disrupt coastal ecosystems and accelerate global warming through a dangerous feedback loop.
