Figure 2

The Dome C temperature anomaly record with respect to the mean temperature of the last millennium8 (based on original deuterium data interpolated to a 500-yr resolution), plotted on the EDC3 timescale13, is given as a black step curve. Data for CO2 are from Dome C (solid circles in purple5, blue4, black: this work, measured at Bern; red open circles: this work, measured at Grenoble), Taylor Dome6 (brown) and Vostok1,2,3 (green). All CO2 values are on the EDC3_gas_a age scale26. Horizontal lines are the mean values of temperature and CO2 for the time periods 799–650, 650–450, 450–270 and 270–50 kyr bp. Glacial terminations are indicated using Roman numerals in subscript (for example TI); Marine Isotope Stages (MIS) are given in italic Arabic numerals27.
