Bellamy, Rob; et al. (2012): A review of climate geoengineering appraisals

Bellamy, Rob; Chilvers, Jason; Vaughan, Naomi E.; Lenton, Timothy M. (2012): A review of climate geoengineering appraisals. In: WIREs Clim Change 3 (6), S. 597–615. DOI 10.1002/wcc.197

"Appraisals of geoengineering are critically reviewed here for the first time using a systematic literature search and screen strategy. Substantial variability between different appraisals' outputs originates from usually hidden framing effects relating to contextual and methodological choices."

Laboratory Equipment: Solar Geoengineering is Feasible, Affordable

Media response to the cost analysis of McClellan et al. "The researchers make it clear that they have not sought to address the science of aerosols in the stratosphere, nor issues of risk, effectiveness or governance that will add to the costs of solar radiation management geoengineering. "
