Atmospheric constraints on changing global biogeochemistry

This talk will cover insights from the study of long-term trends in atmospheric CO2, O2, and CO2 isotopes. In addition to documenting the evolving land and ocean carbon sinks, these data also resolve other emergent phenomena, including major changes in the seasonal cycling of CO2, ongoing loss of O2from the oceans (“ocean deoxygenation”), and global-scale reductions in the water-requirements of vegetation.
