Carbon Feedbacks in Earth's Climate System: Using Ocean and Land Variability to Diagnose Critical Carbon Cycle Processes I
Submit an Abstract to this Session
Session ID#: 32426
Session Description:
The surface fluxes of the main greenhouse gases (CO2, CH4, N2O) are controlled by biogeochemical and physical processes in the land and ocean that are sensitive to changes in climate and atmospheric composition. Terrestrial carbon reservoirs contain at least five times and ocean carbon reservoirs contain at least fifty times more carbon than the atmosphere. Thus limitations in our understanding of carbon cycle processes and their sensitivities to climate variability can lead to large uncertainties in predicting global terrestrial fluxes, as well as regional ocean fluxes. Identifying critical carbon cycle processes and diagnosing their sensitivity to climate is vital for improving future climate predictions. This session will focus on novel drivers and new insights on inter-annual to decadal variability of terrestrial and ocean fluxes of carbon and nitrogen as well as turnover times of various carbon reservoirs to constrain future climate-carbon cycle feedbacks, both from observational and modelling perspectives.
