Abrupt Antarctic Ocean Regime Shift: Reversed SMOC - Southern Meridional Overturning Circulation
A crucial new, vitally important finding shows that the Southern Meridional Overturning Circulation (SMOC), which is the southern hemisphere version of the AMOC (Atlantic Meridional Overturning Circulation) ocean current system has not only stopped, but has actually REVERSED DIRECTION.
The immediate consequences of this reversal is to bring warm, salty water to the surface layers of the ocean around Antarctica, causing a very rapid decline of sea ice around Antarctica since 2015.
Longer term consequences include AMOC disruptions, switch of southern ocean carbon sink to carbon source, and doubling of CO2 in the atmosphere, not to mention huge increases in extreme weather disruption around the planet.
