Abstract
An accurate reconstruction of past 13C/12C ratios of atmospheric CO2 may provide key constraints on the historical activity of the biosphere as CO2 source or sink. Tree rings appear to be a repository of this information but there is much noise in the collection of previous reconstructions, presumably associated with site selection, radial variability, choice of representative wood chemical constituent, and subtle effects of climate on fractionation. -from Authors
