北极永久冻土解冻速度加快增加了河流侵蚀率,影响到基础设施、野生生物生境和北极村庄。 Accelerated Arctic permafrost thawing increases river erosion rates, impacting infrastructure, wildlife habitats, and Arctic villages.
北极的含硫永久冻土正在加速河流侵蚀,尤其影响到阿拉斯加的Koyukuk河。 Thawing permafrost in the Arctic is accelerating river erosion, particularly affecting the Koyukuk River in Alaska. 加州理工学院的一项研究表明,随着永久冻土融化,侵蚀率可能上升30%至100%,威胁到基础设施和野生动物生境。 A Caltech study indicates that as permafrost melts, erosion rates could increase by 30-100%, threatening infrastructure and wildlife habitats. 永久冻土目前减缓了47%的河流迁移速度,但其损失可能会破坏河岸的稳定,对43%位于河流附近的北极村庄造成风险。 Permafrost currently slows river migration by 47%, but its loss may destabilize riverbanks, posing risks to 43% of Arctic villages located near rivers. 继续研究对于消除这些影响至关重要。 Continued research is essential to address these impacts.
