Humphrey, V.; et al. (2018): Sensitivity of atmospheric CO2 growth rate to observed changes in terrestrial water storage

Humphrey, V.; Zscheischler, J.; Ciais, P.; Gudmundsson, L.; Sitch, S.; Seneviratne, S. I. (2018): Sensitivity of atmospheric CO2 growth rate to observed changes in terrestrial water storage. In: Nature 560 (7720), S. 628–631. DOI: 10.1038/s41586-018-0424-4.

„We show that the CO₂ growth rate is strongly sensitive to observed changes in terrestrial water storage, drier years being associated with faster atmospheric CO₂ growth. We demonstrate that this global relationship is independent of known temperature effects and is underestimated in current carbon cycle models. Our results indicate that interannual fluctuations in terrestrial water storage strongly affect the terrestrial carbon sink and highlight the importance of the interactions between the water and carbon cycles.“
