We present a new high-resolution record of atmospheric CO2 from the Siple Dome ice core, Antarctica, over the early Holocene (11.7-7.4 ka) that quantifies natural CO2 variability on millennial timescales under interglacial climate conditions. Atmospheric CO2 decreased by ∼10 ppm between 11.3 and 7.3...
