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,

The world's strongest ocean current could slow as melting Antarctic ice sheets flood it with fresh water, according to research published on Monday that warned of "severe" climate consequences. Scientists used one of Australia's most powerful supercomputers to model how melting ice sheets might change the Antarctic Circumpolar Current,
