However, the mechanisms for Sun-climate linkages remain a topic of debate. Here we present a high-resolution summer sea-surface temperature (SST) record covering the last 9300 yr from a site located at the present-day boundary between Polar and Atlantic surface-water masses. The record is age-constrained via the identification of 15 independently-dated tephra markers from terrestrial archives, circumventing marine reservoir age variability problems. Our results indicate a close link between solar activity and SSTs in the northern North Atlantic during the past 4000 years. They suggest that the climate system in this area is more susceptible to the influence of solar variations during cool periods with less vigorous ocean circulation. Furthermore, the high-resolution SST record indicates that climate in the North Atlantic regions follows solar activity variations on multi-decadal to centennial time scales. STUDY NOTES: A subdecadal (youngest part of record) to multi-decadal (oldest part of record) resolution time series of sea surface temperature (SST) spanning the last 9300 years is reconstructed by using diatom-based transfer function on data from core MD99-2275, north of Iceland. Shifts between cold and warm SST strongly correlated to solar forcing during last 4000 years.
