Ye, Y.; et al. (2019): Dramatic differences in carbon dioxide adsorption and initial steps of reduction between silver and copper

Ye, Y.; Yang, H.; Qian, J.; Su, H.; Lee, K.; Cheng, T. et al. (2019): Dramatic differences in carbon dioxide adsorption and initial steps of reduction between silver and copper. In: Nat Comms 10 (1), S. 1875. DOI: 10.1038/s41467-019-09846-y.

"Converting carbon dioxide (CO2) into liquid fuels and synthesis gas is a world-wide priority. But there is no experimental information on the initial atomic level events for CO2 electroreduction on the metal catalysts to provide the basis for developing improved catalysts. Here we combine ambient pressure X-ray photoelectron spectroscopy with quantum mechanics to examine the processes as Ag is exposed to CO2 both alone and in the presence of H2O at 298 K."

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."

Politico: How John Delaney would address climate change

"Delaney, like many other candidates, says his plan would drive the U.S. to net-zero emissions by 2050, meaning any remaining greenhouse gas pollution at that time would be offset by reforestation or other techniques that remove carbon from the atmosphere."

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."

Call for Abstracts: Aerosol Approaches to Climate Engineering. Robert Dickinson Symposium (AMS100)

Deadline: 1. August 2019

"This joint session covers broad topics such as results from climate modeling, using analogs such as volcanic eruptions and ship tracks, and development of technology to actually implement solar geoengineering. Papers on the physics of climate engineering should be submitted to this joint session, and on ethical and governance issues related to climate engineering to the session "Ethics and governance of weather modification and geoengineering" at the 22nd Conference on Planned and Inadvertent Weather Modification. Invited keynote speaker: Simone Tilmes (NCAR). Session Chair: Alan Robock (Rutgers University)."

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.
 
"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."
