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."

"The effect of solar geoengineering on terrestrial primary productivity is typically much smaller than that of CO₂ fertilization. Changes in the partitioning between direct and diffuse radiation in response to stratospheric aerosol injection could substantially alter modeled plant productivity. Inclusion of the nitrogen cycle would further modify the terrestrial response to solar geoengineering."

"But there’s another way to tackle the problem: Remove carbon from the air. That was the topic of a provocative session at VERGE 2015 in San Jose last week at which Noah Deich, founder of a non-profit business incubator called the Center for Carbon Removal, discussed the concept with several scientists and entrepreneurs working on in the field."
