Flegal, J.; et al. (2019): Solar Geoengineering: Scientific, Legal, Ethical, and Economic Frameworks

Flegal, J.; Hubert, A.; Morrow, D.; Moreno-Cruz, J. (2019): Solar Geoengineering: Scientific, Legal, Ethical, and Economic Frameworks. In: Annu. Rev. Environ. Resour. 44 (1). DOI: 10.1146/annurev-environ-102017-030032.

"Solar geoengineering research in the social sciences and humanities has largely evolved in parallel with research in the natural sciences. In this article, we review the current state of the literature on the ethical, legal, economic, and social science aspects of this emerging area. We discuss issues regarding the framing and futures of solar geoengineering, empirical social science on public views and public engagement, the evolution of ethical concerns regarding research and deployment, and the current legal and economic frameworks and emerging proposals for the regulation and governance of solar geoengineering."

Call for Abstracts: Aerosol Approaches to Climate Engineering (AMS100)

Deadline: 8. 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."

Galina, N.; et al. (2019): Evolution of carbon capture and storage by mineral carbonation. Data analysis and relevance of the theme

Galina, N.; Arce, G.; Ávila, I. (2019): Evolution of carbon capture and storage by mineral carbonation. Data analysis and relevance of the theme. In: Minerals Engineering 142, S. 105879. DOI: 10.1016/j.mineng.2019.105879.

"Mineral carbonation has enormous potential for carbon capture and storage (CCS). CO2 is a greenhouse gas that can be converted into environmentally stable products through mineral carbonation, which has been pointed out as the most promising technology to reduce CO2 emissions and environmental impacts generated therefrom."

Bloomberg Businessweek: We Already Have the World’s Most Efficient Carbon Capture Technology

"To help battle global warming, companies around the world are expected to spend billions of dollars over the next decade building devices aimed at sucking carbon from the atmosphere. The thing is, Mother Nature already made one. While each acre of most tree species can capture and store 1.1 to 9.5 metric tons of carbon dioxide a year, an acre of empress trees can absorb 103."

The Guardian: Sucking carbon out of the air is no magic fix for the climate emergency

"Negative emissions tech is important, but the idea it could replace decarbonisation is pure fantasy. Business as usual is not an option."

Jacobson, R.; et al. (2019): Opportunities for Carbon Dioxide Removal Within the United States Department of Agriculture

Jacobson, R.; Sanchez, D. (2019): Opportunities for Carbon Dioxide Removal Within the United States Department of Agriculture. In: Front. Clim. 1, S. 69. DOI: 10.3389/fclim.2019.00002.

"Farming and ranching communities in the United States sit at the front lines of climate change impacts and responses. In particular, terrestrial atmospheric carbon dioxide removal (CDR) can reduce climate change impacts while increasing resilience to extreme weather. Currently, many CDR technologies and strategies are still under research and development (R&D), and lack sufficient federal support to reach widespread deployment. Here, we provide an assessment of the United States Department of Agriculture's (USDA) existing programs and organizational structure, its capacity to support research and demonstration of CDR, and recommendations for expansion of these capabilities."

Lin, M.; et al. (2019): An Experimental- and Simulation-Based Evaluation of the CO 2 Utilization Efficiency of Aqueous-Based Electrochemical CO 2 Reduction Reactors with Ion-Selective Membranes

Lin, M.; Han, L.; Singh, M.; Xiang, C. (2019): An Experimental- and Simulation-Based Evaluation of the CO 2 Utilization Efficiency of Aqueous-Based Electrochemical CO 2 Reduction Reactors with Ion-Selective Membranes. In: ACS Appl. Energy Mater. DOI: 10.1021/acsaem.9b00986.

"The CO2 utilization efficiency of three types of electrochemical CO2 reduction (CO2R) reactors by using different ion-selective membranes, including anion exchange membrane (AEM), cation exchange membrane (CEM), and bipolar membrane (BPM), was studied quantitatively via both experimental and simulation methods."

ScienceDaily: Clearing up the 'dark side' of artificial leaves

"While artificial leaves hold promise as a way to take carbon dioxide -- a potent greenhouse gas -- out of the atmosphere, there is a 'dark side to artificial leaves that has gone overlooked for more than a decade,' according to Meenesh Singh, assistant professor of chemical engineering in the University of Illinois at Chicago College of Engineering."

Friedmann, J. (2019): Engineered CO2 Removal, Climate Restoration, and Humility

Friedmann, J. (2019): Engineered CO2 Removal, Climate Restoration, and Humility. In: Front. Clim. 1, S. 247. DOI: 10.3389/fclim.2019.00003.

"Over the past 200 years, humans have dramatically altered our global environmental envelope accidentally through uncontrolled greenhouse gas emissions. Humans have also developed the technology to both stop emitting greenhouse gases and ultimately to remove them from the atmosphere through a combination of natural and engineered pathways."
