A global compilation of d13C data from fossil leaves and bulk terrestrial organic matter (TOM) spanning the past 30 k.y., however, shows wide variability and no discernable trend. Here we analyze these data in terms of a relative change in net carbon isotope fractionation between the d13C value of plant tissue and that of atmospheric CO2 [D13C = (d13CCO2 – d13C)/(1 + d13C/1000)] and identify a global 2.1‰ shift in leaf and TOM D13C that is synchronous with a global rise in pCO2 documented from ice core data. We apply a relationship describing the effect of pCO2 on D13C to the global record of D13C change documented here to reconstruct pCO2 levels across the past 30 k.y. Our reconstructed pCO2 levels are in excellent agreement with the ice core data and underscore the potential of the global terrestrial d13C record to serve as an accurate pCO2 proxy NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact NCEI Contact Information Information for contacts at NCEI. information distributor In most cases, electronic downloads of the data are free.
