Ice core evidence indicates that even though atmospheric CO 2 concentrations did not exceed ∼300 ppm at any point during the last 800 000 years, East Antarctica was at least ∼3-4 • C warmer than pre-industrial (CO 2 ∼280 ppm) in each of the last four interglacials. During the previous three interglacials, this anomalous warming was short 5 lived (∼3 000 years) and apparently occurred before the completion of Northern Hemisphere deglaciation. Hereafter, we refer to these periods as "Warmer than
