> Meanwhile the long-standing concern about a shutdown of the ocean circulation in the North Atlantic sometime in the 21st century appears to be subsiding. A Swiss study[1] published this month found that, contrary to past belief, the circulation did not fail at the end of the last ice age, suggesting, the researchers say, that it was more stable than previously supposed, and less likely to collapse.

> A new analysis by Australian and American researchers, using new and more detailed modeling of the oceans, predicts that the long-feared turn-off of the circulation will likely occur in the Southern Ocean, as billions of tons of ice melt on the land mass of Antarctica. And rather than being more than a century away, as models predict for the North Atlantic, it could happen within the next three decades.
> It predicts a 42 percent decline in deep-water formation in the Southern Ocean by 2050. This is more than twice the 19 percent they predict for an equivalent event in the North Atlantic.
> And after 2050, their model predicts that things will get even worse. Deep-water formation “looks headed towards collapse this century,” the coordinator of the study, Matthew England of the University of New South Wales, told Yale Environment 360. “And once collapsed, it would most likely stay collapsed until Antarctic melting stopped. At current projections that could be centuries away.”
