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.
