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.
The blue curve shows an early decrease already in the 19th century, which Thornalley and colleagues attribute to an earlier warming at the end of the
so - called «Little Ice Age», when the inflow of meltwater could have slowed the
formation of
deep water in the Labrador Sea.
