Melting ice sheets are slowing the Antarctic Circumpolar Current (ACC), the world's strongest ocean current, researchers have found. This melting has implications for global climate indicators, including sea level rise,

Melting Antarctic ice could slow the Antarctic Circumpolar Current by 20% by 2050, disrupting climate, rising sea levels, and harming marine ecosystems.

A new study shows melting Antarctic ice changes the density of ocean layers around Antarctica, driving a slowdown of the Antarctic Circumpolar Current.
