Prognostic simulation of
carbon sequestration and carbon management must provide for the influence of
potential changes in future atmospheric CO2 concentrations and
climate on carbon cycle processes. The
conventional approach is to use various scenarios of changes in atmospheric CO2
and climate as external inputs to carbon cycle models. However, this approach decouples potentially
important feedbacks between the carbon cycle and climate, and thus contributes
uncertainty to the simulation of future carbon sequestration and the evaluation
of carbon management options. Here we
describe modeling results that analyze components of this uncertainty. We describe how coupling a carbon management model
with a climate model in fully coupled climate-carbon simulations influences the
analysis and interpretation of terrestrial ecosystem sequestration
as an option for future carbon management.
