Antarctic ice cores can be used to reconstruct atmospheric CO2 concentrations, revealing significant changes during the Holocene epoch which started 11,000 years ago. Here, a highly resolved δ13C record is presented for the past 11,000 years from measurements on atmospheric CO2 trapped in an Antarctic ice core. These data are combined with a simplified carbon cycle model to shed light on the processes responsible for the changes in CO2 concentrations.
