Atlantic Meridional Overturning Circulation (AMO)

Our results, based on several independent indices, show that AMO changes since the 1940s are best explained by multidecadal variability, rather than an anthropogenically forced trend. Leading indicators in the subpolar North Atlantic today suggest that the current AMO decline is ending. We expect a prolonged AMO(C) minimum, probably lasting about two decades. If prior patterns hold, the resulting low levels of oceanic heat uptake will manifest as a period of rapid global surface warming.
