Ok I see what you are refering to now, the thermo haline circulation.
I would say that any effect that warming would have on this is likely to
be self limiting.
If the thermo haline circulation falters and produces local cooling in
the northern hemisphere
the runoff from greenland will halt, restarting the circulation. This is
unlike the younger dryas or 8k event
when impounded glacial lakes of huge extent seem to have been released.
There are no comparable lakes
on greenland.
