Top: One sigma-calibrated age ranges for the14C control points 1, 2 and 6 as an indicator of the possible age range of the CO2 record reconstructed from stomatal frequency. The labels are the same as in Wagner et al. (1). Center and Bottom: Atmospheric CO2 concentration reconstructed from stomatal index (•) (1) and direct measurements of CO2 concentration of air enclosed in bubbles in the ice cores from Taylor Dome (⋄) (3, 4) and Vostok (□) (7, 8).
