The Lawretanian: Visiting lecturer discusses moral quandaries in geoengineering

Report on a talk by Bjornar Egede-Nissen. "He admitted that there are some justifications of doing SRM research, including the cost-benefit analysis, the value of scientific research and the emergency options for SRM research. According to Egede-Nissen, the SRM can be comparatively cheap, but the long time-frame required and the side effects of doing SRM research can be cause for reconsideration."

Science Blogs: Who Should Pay for Solar Geoengineering Liability?

"If some (company, or govt) puts up mirror-satellites to reduce incoming solar, and accidentally fries Australia, is that really the fault of those who put the CO2 in the atmosphere?"

McCusker, Kelly E.; et al. (2014): Rapid and extensive warming following cessation of solar radiation management

McCusker, Kelly E.; Armour, Kyle C.; Bitz, Cecilia M.; Battisti, David S. (2014): Rapid and extensive warming following cessation of solar radiation management. In Environ. Res. Lett. 9 (2), p. 24005–24005. DOI 10.1088/1748-9326/9/2/024005.

"Here, we consider the scenario in which SRM—via stratospheric aerosol injection—is terminated abruptly following an implementation period during which anthropogenic GHG emissions have continued."

truthout: What Is Climate Geoengineering? Word Games in the Ongoing Debates Over a Definition

"The precise details of that definition are important for various reasons, not the least of which is that it will determine what likely is to be subjected to the scrutiny and potentially complex and difficult legal governance processes that such a global scale climate-tweak effort would necessarily involve."

Pitari, Giovanni; et al. (2014): Stratospheric Ozone Response to Sulfate Geoengineering: Results from the Geoengineering Model Intercomparison Project (GeoMIP)

Pitari, Giovanni; Aquila, Valentina; Kravitz, Ben; Robock, Alan; Watanabe, Shingo; Cionni, Irene et al. (2014): Stratospheric Ozone Response to Sulfate Geoengineering: Results from the Geoengineering Model Intercomparison Project (GeoMIP). In J. Geophys. Res. Atmos., pp. n/a. DOI 10.1002/2013JD020566.

"Here we present the effects that increased amounts of sulfate aerosol have on stratospheric meteorology and/or ozone concentrations, as simulated by two general circulation models and two coupled chemistry-climate models within the experiments G3 and G4 of the Geoengineering Model Intercomparison Project (GeoMIP)."

Berdahl, Mira; et al. (2014): Arctic Cryosphere Response in the Geoengineering Model Intercomparison Project (GeoMIP) G3 and G4 scenarios

Berdahl, Mira; Robock, Alan; Ji, Duoying; Moore, John C.; Jones, Andy; Kravitz, Ben; Watanabe, Shingo (2014): Arctic Cryosphere Response in the Geoengineering Model Intercomparison Project (GeoMIP) G3 and G4 scenarios. In J. Geophys. Res. Atmos., pp. n/a. DOI 10.1002/2013JD020627.

"We analyzed output from the Geoengineering Model Intercomparison Project (GeoMIP) for the two most “realistic” scenarios, which use the Representative Concentration Pathway of 4.5 Wm-2 by 2100 (RCP4.5) as the control run and inject sulfate aerosol precursors into the stratosphere."
