AMOC stability depends on warming rate, not just temperature
↗
New research shows the AMOC's stability depends on the rate of warming, not just the final temperature.
WHY IT MATTERS
The AMOC's stability depends on how fast the climate warms, not just how much. This means the speed of emissions reductions directly affects the risk of a collapse that would disrupt regional climates and ocean circulation.
Written by elseif from the cluster below · every claim links back to a sourceThe three things worth knowing
01
Under slow warming, the AMOC remained stable beyond +4°C and did not collapse even at +5°C.
02
Under fast warming, the AMOC collapsed at around +2°C.
03
The critical warming rate is around 0.3°C per decade, a pace the world is already approaching.

Rapid warming may tip AMOC at 2°C, slower warming may avert collapse
