The Antarctic Circumpolar Current (ACC), the most powerful on Earth, was subject in the past to substantial natural fluctuation. During glacial periods, the current flow speed in the South Pacific slowed; while during interglacials, it accelerated. Consequently, if the current global warming intensifies in the future, it could mean that the Southern Ocean stores less CO2 and that more heat reaches Antarctica affecting the stability of its ice sheets.
