Researchers say the Southern Ocean processes that shield the deep ocean from warming began changing around 2016, linked to shifts around Antarctica in sea ice and ocean circulation. The change was observed near Australia and New Zealand, and scientists reportedly cannot yet predict what it means for long-term ocean heat uptake and global warming.

Why now: New attention on an apparent regime shift in deep ocean heat protection raises uncertainty about future climate impacts.
