An Australian-led study predicts that the Antarctic Circumpolar Current may slow by 20% by 2050 due to high emissions. This current is crucial for regulating global climate by impacting heat and carbon dioxide uptake in oceans. The study’s results indicate a troubling link between meltwater from Antarctica and the slowdown of this current, which has significant implications for global climate dynamics and marine ecosystems. As ice melts and fresh water is released into the ocean, the current’s movement is disrupted, possibly leading to severe climate impacts and reduced carbon storage capacity in oceans.
In a projected high emissions future, the Antarctic Circumpolar Current is expected to slow by 20% by 2050, intensifying ice melt and sea level rise.
Researchers found a direct connection between Antarctic ice melt and the slowdown of the circumpolar current, suggesting significant reconfiguration of Southern Ocean dynamics.
