一项研究警告南极北极洋流到2050年可能放缓20%,扩大气候变化的影响。 A study warns the Antarctic Circumpolar Current may slow by 20% by 2050, amplifying climate change effects.

《环境研究信》的一项新研究警告说,由于冰盖融化,南极北极洋流这一最强的洋流到2050年可能会减速20%。 A new study in Environmental Research Letters warns that the Antarctic Circumpolar Current, the strongest ocean current, could slow by 20% by 2050 due to melting ice sheets. 减速可能导致气候变异性加剧,天气更加极端,全球升温速度加快。 This slowdown could cause increased climate variability, more extreme weather, and faster global warming. 淡水的流入改变了海洋的盐含量,影响到冷水如何流通。 The influx of freshwater changes the ocean's salt content, affecting how cold water circulates. 这还有可能使入侵物种进入南极洲。 This also risks allowing invasive species to reach Antarctica. 即使将全球变暖限制在1.5摄氏度以内,也仍然能看到目前的减缓。 Even limiting global warming to 1.5°C could still see the current slow down.
