It has been suggested that global warming could enhance freshwater discharge into the North Atlantic and shut down the AMO, causing significant cooling. These possible climate effects have attracted a lot of attention, but little thought has been given to what might happen to the marine ecosystem if the AMO were to weaken or disappear. Andreas Schmittner has performed a detailed simulation and finds that a collapse of the AMO would cut global productivity by about 20%. The model results are consistent with the available records of past productivity. The decline in plankton stocks that would accompany changes of that scale could have a dramatic impact on fisheries in the affected areas.
