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 [CI95%] −5.5 to −6.0), representing a decreased carbon dioxide sink of similar magnitude to current annual fossil fuel emissions (8 PgC/year)."

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."

Call for Abstracts: Carbon: Challenges and Opportunities for the 21st Century (AGU 2018)

Deadline: 01. August 2018

"Carbon is an integral building block of life on Earth and has fueled unprecedented economic and societal progress. But with progress has come significant increases in atmospheric carbon dioxide and methane, causing warming and other health and environmental impacts. While efforts to reduce reliance on carbon-based fuels proceed, there is also growing attention to ways to remove carbon from the atmosphere, reliably sequester it, and develop commercial uses for it. Recent National Academies’ reports address scientific and technical issues related to methane emissions monitoring, measurement, and verification; a range of carbon dioxide removal and storage approaches; and utilization of carbon waste streams. This session will expand on these topics, inviting presentations that discuss the challenges and opportunities associated with evolving approaches to manage carbon."

Cao, Long (2018): The Effects of Solar Radiation Management on the Carbon Cycle

Cao, Long (2018): The Effects of Solar Radiation Management on the Carbon Cycle. In Curr Clim Change Rep 8 (2), p. 605. DOI: 10.1007/s40641-018-0088-z.

"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."

Cao, Long; Jiang, Jiu (2017): Simulated effect of carbon cycle feedback on climate response to solar geoengineering

Cao, Long; Jiang, Jiu (2017): Simulated effect of carbon cycle feedback on climate response to solar geoengineering. In Geophys. Res. Lett. DOI: 10.1002/2017GL076546.

"Here we use an Earth system model to investigate interactive feedbacks between solar geoengineering, global carbon cycle, and climate change. We design idealized sunshade geoengineering simulations to prevent global warming from exceeding 2°C above pre-industrial under a CO2 emission scenario with emission mitigation starting from mid-of-century."

GreenBiz: Beyond emissions: The promise of products from captured carbon

"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."
