The fact that the hindcasts
with their method perform worse than a standard IPCC scenario, the number of failed previous cooling predictions, the negative skill in the Gulf Stream and

There is so little understanding about how the ocean parses its response to forcings by 1) suppressing (local convective scale)
deep water formation where excessive warming patterns are changed, 2) enhancing (local convective scale)
deep water formation where the changed excessive warming patterns are co-located
with increased evaporation and increased salinity, and 3) shifting favored
deep water formation locations as a result of a) shifted patterns of enhanced warming, b) shifted patterns of enhanced salinity and c) shifted patterns of circulation which transport these enhanced ocean features to critically altered destinations.
Thus it appears that disruption of
deep water formation in the North Atlantic, via a blob of colder fresher
water coming off of Greenland, would not «shut down» or even affect the Gulf Stream net mass transport at all, but instead would shift its northern return flow southwards,
with many severe regional consequences.
