We compare paleoclimate proxy records from central Greenland and the Aegean Sea to offer new insights into the causes.. timing, and mechanisms of Holocene atmosphere-ocean interactions. A direct atmospheric link is revealed between Aegean sea surface temperature (SST) and high-latitude climate. The major Holocene events in our proxies of Aegean SST and winter/spring intensity of the Siberian High (GISP2 K+ record) follow an similar to2300 year spacing, recognised also in the Delta(14)C record and in worldwide Holocene glacier advance phases, suggesting a solar modulation of climate. We argue that the primary atmospheric response involved decadal-centennial fluctuations in the meridional pressure gradient, driving Aegean SST events via changes in the strength, duration, and/or frequency of northerly polar/continental air outbreaks over the basin. The observed natural variability should be accounted for in predictions of future climate change, and our time-frame for the Aegean climate events in addition provides an independent chronostratigraphic argument to Middle Eastern archaeological studies.
