Carbon Leakage through the Terrestrial-aquatic Interface: Implications for the Anthropogenic CO2 Budget

This contribution reviews the role of the terrestrial-aquatic interface in the global carbon cycle. We highlight that carbon leakage through this interface has profound ramifications for the terrestrial carbon balance and for the anthropogenic CO2 budget. Our budget analysis identifies the need for an integrated process-based quantitative understanding of the terrestrial-aquatic interface that includes its response to anthropogenic perturbations. Complementary observational and modeling efforts in this direction are presented.
