| Abstract | The North Atlantic marine ecosystem has been expected to adjust imminently to a negative phase of the Atlantic Multidecadal Oscillation (AMO). Recent results suggest, however, that the AMO is not a regular internal source of variability, but has been driven by both volcanism and sulphate aerosol emissions that have influenced temperature negatively, and a period of greenhouse gas accumulation causing temperatures to be higher than normal. The demise of the AMO removes the expected and imminent cyclical change from the current warm phase to a negative cool phase in the North Atlantic. Here, we discuss the implications of this new finding for the near-future of North Atlantic marine ecosystems in a context of rapid climate warming. |
