Watson, Andrew J.; et al. (2020): Revised estimates of ocean-atmosphere CO2 flux are consistent with ocean carbon inventory

Watson, Andrew J.; Schuster, Ute; Shutler, Jamie D.; Holding, Thomas; Ashton, Ian G. C.; Landschützer, Peter et al. (2020): Revised estimates of ocean-atmosphere CO2 flux are consistent with ocean carbon inventory. In Nat Comms 11 (1), p. 4422. DOI: 10.1038/s41467-020-18203-3.

"We estimate uncertainties using multiple interpolation methods, finding convergent results for fluxes globally after 2000, or over the Northern Hemisphere throughout the period. Our corrections reconcile surface uptake with independent estimates of the increase in ocean CO₂ inventory, and suggest most ocean models underestimate uptake."

C2G Guest Post: Can we end hunger and reduce CO2 levels at the same time?

"Functioning ecosystems are not only central to the carbon cycle; they are the basis of livelihoods, culture and identity for people. Healthy ecosystems protect biodiversity, water cycles, disaster risk reduction, global health, and – perhaps most crucially of all – food."

Lee, Hanna; et al. (2020): The response of terrestrial ecosystem carbon cycling under different aerosol-based radiation management geoengineering

Lee, Hanna; Muri, Helene; Ekici, Altug; Tjiputra, Jerry; Schwinger, Jörg (2020): The response of terrestrial ecosystem carbon cycling under different aerosol-based radiation management geoengineering. In Earth Syst. Dynam. DOI: 10.5194/esd-2020-57.

"We find that changes in vegetation carbon storage under geoengineering application was much smaller than what is exhibited under RCP4.5 scenario that uses climate mitigation efforts by afforestation in the tropics. Hence, it would be important to consider the multiple combined effects and responses of land biomes when applying different strategies to reach the global temperature targets of the Paris Agreement."

Suarez, Celina A. (2019): Earth Catastrophes and Their Impact on the Carbon Cycle

Suarez, Celina A. (2019): Earth Catastrophes and Their Impact on the Carbon Cycle. Elements. October 2, 2019. http://elementsmagazine.org/2019/10/02/earth-catastrophes-impact-carbon-cycle/.

"This issue will focus on the origins of carbon on Earth, the roles played by large-scale catastrophic carbon perturbations in mass extinctions, the movement and distribution of carbon in large igneous provinces, and the role carbon plays in icehouse–greenhouse climate transitions in deep time."

Kovenock, M.; et al. (2018): Leaf Trait Acclimation Amplifies Simulated Climate Warming in Response to Elevated Carbon Dioxide

Kovenock, M.; Swann, A. (2018): Leaf Trait Acclimation Amplifies Simulated Climate Warming in Response to Elevated Carbon Dioxide. In: Global Biogeochem. Cycles 165 (2), S. 351. DOI: 10.1029/2018GB005883.

"Here we show that one leaf trait acclimation in response to elevated carbon dioxide—a one‐third increase in leaf mass per area—significantly impacts climate and carbon cycling in Earth system model experiments. Global net primary productivity decreases (−5.8 PgC/year, 95% confidence interval [CI_95%] −5.5 to −6.0), representing a decreased carbon dioxide sink of similar magnitude to current annual fossil fuel emissions (8 PgC/year)."
