Does anyone here know how or when AMOC is restarted after a shutdown?
How it used to get restarted in past climate changes. And how that restart would play out under our unusual changed factors?
I was thinking that maybe, a restart requires all Milankovic cycles to sufficiently favour Northern Hemisphere. And the process would be that sufficiently warmer summer temperatures over the Northern North Atlantic manage to evaporate enough ocean water for it to become saltier – and that would kickstart convection in place, with strictly local conditions as the first engine.
All 3 Milankovic cycles sufficiently favouring Northern Hemisphere, that's in about 120,000 years....
