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.","author":{"name":"Hui Jiang, Raimund Muscheler, Svante Björck, Marit-Solveig Seidenkrantz, Jesper Olsen, Longbin Sha, Jesper Sjolte, Jón Eiríksson, Lihua Ran, Karen-Luise Knudsen, Mads F.
