We concluded in our IceMelt paper,14 based on observed rates of ice shelf melting, that the world is nearing shutdownof the Atlantic Overturning Meridional Circulation (AMOC) and shutdown of deepwaterformation near Antarctica (which we term SMOC for its analogy to the Northern Hemisphereprocess), if the rate of ice melt continues to grow.
for - question - climate crisis - AMOC - does Jim Hansen consider shutdown of AMOC irreversible?
