    salinity changes, not temperature

    temperature melt driven salinity changes.

    how much heat AMOC carries from the equator to northern europe, and also try to see how much air it’s heating in the atmosphere.

    the physics experiment should include heat in oceans trapped below surface. The different heat flow from 35C Florida oceans in October vs what used to be 28C even at slower flow rate. How a 2 delta melt rate one season could reduce the melt rate next season, how Greenland melt into 10C water instead of 2C water would increase the southward flow rate that increases/maintains the north flow. Salinity normalizes within 3 months. Early summer melt will be low at low winter freeze rates, by theory increasing Carribean north flow, late summer south flow will be warmer.

    Observations since 2016 data paper have been the opposite warming of Europe in winter.

      Yeah your just missing two key facts here. One, yeah europe is still getting warmer, AMOC hasn’t collapsed. Two, the conditions for maintaining a convective current are significantly easier than starting one. So if AMOC collapses and Greenland ice stops melting, there’s no guarantee AMOC will restart. And even if it does, it could take centuries.
