For global warming scenarios, additional forcing comes into play: surface warming and enhanced high - latitude precipitation, which will also reduce density of northern surface waters (an effect which alone has shut down deep
water formation in some model experiments, e.g. Manabe and Stouffer 1993, 1994).
Vertical diffusion is slower, but happens over most of the oceans, while downward advection of anomalously warm water happens in fewer spots but is faster (the North Atlantic, «Mode» water formation regions north of the Antarctic Circumpolar Current, shelf
water formation in Antarctica).
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.

water formation in the north Atlantic.
If there is deep -
water formation in the final steady state as in the present day, the ocean will eventually warm up fairly uniformly by the amount of the global average surface temperature change (Stouffer and Manabe, 2003), which would result in about 0.5 m of thermal expansion per degree celsius of warming, calculated from observed climatology; the EMICs in Figure 10.34 indicate 0.2 to 0.6 m °C — 1 for their final steady state (year 3000) relative to 2000.
Martinson, D. G. in Deep Convection and Deep
Water Formation in the Oceans (eds Chu, P. C. & Gascard, J. C.) 37 — 52 (Elsevier Oceanography Series, 1991).
Most LGM simulations with coupled models shift the deep -
water formation in the North Atlantic southward, but large differences exist between models in the intensity of the Atlantic meridional overturning circulation.
It has been fairly well understood for quite some time that reduced deep
water formation in the North Atlantic (due to freshening surface waters) will not plunge Europe into a new Ice Age.
In a version of the model without Drake Passage the temperature distribution is symmetric about the equator, due in large part to the fact that the meridional overturning in the ocean is symmetric about the equator with deep
water formation in both hemispheres.
