We present a new high-resolution record of atmospheric CO 2 from the Siple Dome ice core, Antarctica, over the early Holocene (11.7–7.4 ka) that quantifies natural CO 2 variability on millennial timescales under interglacial climate conditions. Atmospheric CO 2 decreased by ∼10 ppm between 11.3 and...
