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."
