A soderhamn ottoman cover new, decadally resolved record of the <sup>10</sup>Be peak at 41 kyr from the EPICA Dome C ice core (Antarctica) is used to match it with the same peak in the GRIP ice core (Greenland).This permits a direct synchronisation of the climatic variations around this time period, independent of uncertainties related to the ice age-gas age difference in ice cores.Dansgaard-Oeschger event 10 is in the period of best synchronisation and is here found to be coeval with an Antarctic temperature maximum.Simulations using a thermal bipolar seesaw model agree reasonably well with the observed relative climate chronology in these two cores.They also reproduce three Antarctic warming events observed between A1 and A2.
