In a high emissions future, the world’s strongest ocean current could slow down by 20% by 2050, further accelerating Antarctic ice sheet melting and sea level rise, an Australian-led study has found.
The Antarctic Circumpolar Current – a clockwise current more than four times stronger than the Gulf Stream that links the Atlantic, Pacific and Indian oceans – plays a critical role in the climate system by influencing the uptake of heat and carbon dioxide in the ocean and preventing warmer waters from reaching Antarctica.
