[Settled science?]: Have aerosols caused the observed North Atlantic multidecadal variability? @ Weather and Climate Discussion
So where are we? Because of the important impacts of NASST on regional climates, especially regions sensitive rainfall (e.g. the Sahel), understanding and predicting the multidecadal changes in NASST remains a key challenge. Given the evidence it seems likely that anthropogenic aerosol have had an impact on past NASST variability, especially in the Tropics. However, given the disagreement of the simulated changes in HadGEM2-ES with those observed it is clear that further understanding is needed. For instance, what was the magnitude of the aerosol affects, and did the anthropogenic aerosol influence the phasing of the natural variability by forcing dynamical feedbacks, as has been suggested recently for Volcanic forcing.
