Amoc

Atlantic Meridional Overturning Circulation (AMOC)

Our results, based on several independent indices, show that AMOC changes since the 1940s are best explained by multidecadal variability6, rather than an anthropogenically forced trend. Leading indicators in the subpolar North Atlantic today suggest that the current AMOC decline is ending. We expect a prolonged AMOC 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.

The Pacific Decadal Oscillation (PDO)

PDO is an internal switch between two slightly different circulation patterns that occurs every 30 years or so in the North Pacific Ocean
