Historical Isotopic Temperature Record from the Vostok Ice Core
The strong correlation between atmospheric greenhouse-gas concentrations and Antarctic temperature, previously described by Barnola et al. (1987), is confirmed by the extension of the Vostok ice-core record (Petit et al. 1999). From the extended Vostok record, Petit et al. (1999) concluded that pres...
