Boucher, Olivier (2015): Aerosol-Based Climate Engineering

Boucher, Olivier (2015): Aerosol-Based Climate Engineering. In: Atmospheric Aerosols. Edited by Olivier Boucher. Dordrecht: Springer Netherlands, pp. 287–294. DOI 10.1007/978-94-017-9649-1_13

"This chapter introduces climate engineering as a range of techniques aiming to alleviate the impacts of climate change. Two aerosol-based techniques, known as stratospheric aerosol injection and marine cloud brightening, are discussed in terms of their potential, side effects, and shortcomings."

Berkey, Brian (2014): State Action, State Policy, and the Doing/Allowing Distinction

Berkey, Brian (2014): State Action, State Policy, and the Doing/Allowing Distinction. In Ethics, Policy & Environment 17 (2), pp. 147–149. DOI 10.1080/21550085.2014.926074.

Response to Morrow, David R. (2014). "On his view, the moral significance of the doing/allowing distinction entails that the improven in the overall risk provile would have to be very large in order for state deployment of SRM to be permissible, since SRM would involve the state in doing harm to some, while refusing to deploy it would involve the state in merely allowing harm to befall others as a result of climate change."

Kravitz, Ben; Robock, Alan; et al. (2012): Sensitivity of stratospheric geoengineering with black carbon to aerosol size and altitude of injection

Kravitz, Ben; Robock, Alan; Shindell, Drew T.; Miller, Mark A. (2012): Sensitivity of stratospheric geoengineering with black carbon to aerosol size and altitude of injection. In: J. Geophys. Res 117 (D9), pp. 1–22. doi:10.1029/2011JD017341

"Simulations of stratospheric geoengineering with black carbon (BC) aerosols using a general circulation model with fixed sea surface temperatures show that the climate a general circulation model with fixed sea surface temperatures effects strongly depend on aerosol size and altitude of injection."
