Abstract

We examine results from E3SM v1 BGC simulations, characterizing the degree to which land and atmosphere carbon cycle feedbacks vary over time under a strong future forcing scenario. We show that there are important changes in both the mean carbon cycle feedbacks over time and in their spatial distributions. We examine results from E3SM v1 and compare to results from the same forcing scenarios for multiple CMIP6 models. We quantify differences in spatial and temporal feedback characterizations among the models and relate these to known differences in model structure and experiment configurations. We quantify the impact of time-varying feedback parameters on linear feedback model predictions.
