Sensitivity of the European LGM climate to North Atlantic sea-surface temperature
International audience Recent reconstructions of Sea-Surface Temperatures (SSTs) for the Last Glacial Maximum (LGM, 21kyr BP) based on foraminifera and dinoflagel!ate proxies suggest that the north Atlantic may have been warmer than estimated by CLIMAP [1981]. To better understand the impact of such...
