Gloomy climate calculation: Scientists predict a collapse of the Atlantic ocean current to happen mid-century (www.sciencedaily.com)

Does anybody know if such a collapse would happen instantaneous or more gradual? With the massive amount of water in motion it feels like it would take a long time to stop, or are fluids behaving differently?

When I used to run simulations, a current of the size of the Gulf Stream could be turned on (with winds and Earth's rotation), from nothing, in around 400 years (see p. 68). Then it maintained steadily. But turning off or changing in important ways can happen much faster. I'd like to know as well. There should be open-access articles in that journal about this.
