In a nutshell • The Antarctic Circumpolar Current, Earth’s strongest ocean current, is projected to weaken by about 20% by 2050 due to freshwater from melting Antarctic ice sheets. • Unlike previous predictions that suggested the current would strengthen with climate change,

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.
