Kallenbach, C.; et al. (2019): Managing Agroecosystems for Soil Microbial Carbon Use Efficiency: Ecological Unknowns, Potential Outcomes, and a Path Forward

Kallenbach, C.; Wallenstein, M.; Schipanksi, M.; Grandy, S. (2019): Managing Agroecosystems for Soil Microbial Carbon Use Efficiency: Ecological Unknowns, Potential Outcomes, and a Path Forward. In: Frontiers in Microbiology 10, S. 51. DOI: 10.3389/fmicb.2019.01146.

„Agricultural systems are increasingly managed for improving soil carbon (C) accumulation. However, there are limits to C returns in agricultural systems that constrain soil C accumulation capacity. […] In this perspective, we consider three complex drivers of agroecosystem CUE that need to be resolved to develop effective C sequestration management practices in the future: (1) the environment as an individual trait moderator versus a filter, (2) microbial community competitive and faciliatory interactions, and (3) spatiotemporal dynamics through the soil profile and across the microbial lifecycle.“

Yahoo Finance: Shell Quest carbon capture and storage project reaches milestone of 4M tonnes

„Shell Canada says the Quest carbon capture and storage project north of Edmonton has reached the milestone of four million tonnes of stored carbon dioxide, equivalent to the annual emissions of about one million cars.It says the accomplishment is ahead of schedule and has been attained at a lower cost than expected.Quest opened in 2015 and cost about $1.35 billion, backed with $745 million from the Alberta government and $120 million from Ottawa.The project was sold to Calgary-based Canadian Natural Resources Ltd. in 2017, along with most of Shell’s Alberta oilsands assets, but is still operated by Shell.The facility captures and stores underground about one-third of the CO2 emissions from the Shell-operated Scotford Upgrader, which turns oilsands bitumen into synthetic crude that can be refined into fuel and other products.“

Bluemling, B.; et al. (2019): Seeding the clouds to reach the sky. Will Chinas weather modification practices support the legitimization of climate engineering?

Bluemling, B.; Kim, R.; Biermann, F. (2019): Seeding the clouds to reach the sky. Will China’s weather modification practices support the legitimization of climate engineering? In AMBIO. DOI: 10.1007/s13280-019-01180-3.

„In this Perspective, we discuss whether in times of quickly proceeding global environmental change, radical global interventions like “climate engineering” may gain legitimacy in China and eventually be deployed or supported. We argue that one cornerstone for whether climate engineering, and solar radiation management in particular, could gain legitimacy in China, is its current weather modification programme.“

Baskin, J. (2019): Geoengineering, the Anthropocene and the End of Nature

Baskin, J. (2019): Geoengineering, the Anthropocene and the End of Nature. Cham: Palgrave Macmillan.

„This book takes a critical look at solar geoengineering as an acceptable means for addressing climate change. Baskin explores the assumptions and imaginaries which animate ‘engineering the climate’ and discusses why this climate solution is so controversial. The book explains geoengineering’s past, its revival in the mid-2000s, and its future prospects including its shadow presence in the Paris climate accord.“

Robrecht, S.; et al. (2019): Mechanism of ozone loss under enhanced water vapour conditions in the mid-latitude lower stratosphere in summer, Atmos

Robrecht, S., Vogel, B., Grooß, J.-U., Rosenlof, K., Thornberry, T., Rollins, A., Krämer, M., Christensen, L., and Müller, R. (2019): Mechanism of ozone loss under enhanced water vapour conditions in the mid-latitude lower stratosphere in summer, Atmos. Chem. Phys., 19, 5805-5833, https://doi.org/10.5194/acp-19-5805-2019, 2019.
[nbsp]
„Water vapour convectively injected into the mid-latitude lowermost stratosphere could affect stratospheric ozone. The associated potential ozone loss process requires low temperatures together with elevated water vapour mixing ratios. Since this ozone loss is initiated by heterogeneous chlorine activation on liquid aerosols, an increase in sulfate aerosol surface area due to a volcanic eruption or geoengineering could increase the likelihood of its occurrence. […] Here, we analyse the ozone loss mechanism and its sensitivity to various stratospheric conditions in detail. By conducting a box-model study with the Chemical Lagrangian Model of the Stratosphere (CLaMS), chemistry was simulated along a 7 d backward trajectory.“

Jackson, R. B.; et al. (2019): Methane removal and atmospheric restoration

Jackson, R. B.; Solomon, E. I.; Canadell, J. G.; Cargnello, M.; Field, C. B. (2019): Methane removal and atmospheric restoration. In Nature Sustainability 10, p.[nbsp]405. DOI: 10.1038/s41893-019-0299-x.

„Zeolites and other technologies should be evaluated and pursued for reducing methane concentrations in the atmosphere from 1,860 ppb to preindustrial levels of ~750 ppb. Such a goal of atmospheric restoration provides a positive framework for change at a time when climate action is desperately needed.“
