Antarctic Circumpolar Current Responds to Global Climate: Study

The Antarctic Circumpolar Current (ACC) is the only ocean current that encircles the Earth without being obstructed by any landmass. Recent studies have shown that during warmer phases, such as the last interglacial period, the ACC flows more rapidly. This change can significantly impact the global climate by affecting other ocean currents like the Gulf Stream, altering weather patterns in regions like Northwest Europe, and potentially decreasing the ocean’s capacity to absorb CO2. This could lead to higher atmospheric CO2 levels and accelerate global warming. Researchers emphasize the importance of understanding the ACC’s role in the global climate system and suggest that its behavior in response to warming trends could provide valuable insights for future climate change predictions and mitigation strategies.
