Abstract:
|
Knowledge of the CO2 concentrations in the past is important to provide a benchmark for how the global carbon cycle varies over time. This project applies the most comprehensive measures of CO2 in Antarctic ice cores and a physically based forward model to infer CO2 concentrations on an annual basis. An interesting feature of this analysis is a more complete characterization of the uncertainty. In particular, Monte Carlo ensembles of the posterior are particularly useful for assessing the size of the decrease in CO2 around 1601.
