Preston, Christopher J. (2012): Ethics and geoengineering: reviewing the moral issues raised by solar radiation management and carbon dioxide removal

Preston, Christopher J. (2012): Ethics and geoengineering: reviewing the moral issues raised by solar radiation management and carbon dioxide removal. In: WIREs Clim Change (online first), DOI 10.1002/wcc.198

"Ethicists, social scientists, and experts in governance have begun the work of addressing these concerns. [...] The wide range of geoengineering technologies currently being discussed makes it prudent that each technique should be evaluated individually for its ethical merit."
