Carbon Isotope Constraints on the Deglacial CO2 Rise from Ice Cores [PDF]

open access: yes, 2012
The stable carbon isotope ratio of atmospheric CO2 (d13Catm) is a key parameter in deciphering past carbon cycle changes. Here we present d13Catm data for the past 24,000 years derived from three independent records from two Antarctic ice cores.
