Controlling for anthropogenically induced atmospheric variation in stable carbon isotope studies
TL;DR: A high-precision record of atmospheric CO2 δ13C from ice cores and direct atmospheric measurements is used to model modern change in CO2 €13C and estimate a correction factor that reduces bias associated with changes in atmospheric isotopic baseline and facilitates comparison of tissue δ 13C collected over multiple years.
