Holocene temperature variations inferred from Antarctic ice cores • SIX
International audience We have reconstructed temperature changes over the past 15 000 years from ice-core data in Antarctica. vVe used measurements of the D/H isotope ratio in ice as a proxy of temperature for central sites (Vostok, Dome C and Komsomolskaya; as well as coastal sites (D47, DIS and DI...
