The Atlantic Meridional Overturning Circulation (AMOC) could weaken under a flood of Greenland meltwater, but this slowdown would be gradual and it would reverse if global warming were halted, according to a state-of-the-art climate model.
The AMOC is a system of currents that brings warm, salty, tropical water into the North Atlantic Ocean, where it cools, sinks and returns southwards along the seabed. Fresh water melting from the Greenland ice sheet appears to be mixing with this dense seawater and slowing its cascade down to the ocean floor.
