Goeppert, Alain; et al. (2012): Air as the renewable carbon source of the future: an overview of CO2 capture from the atmosphere
Goeppert, Alain; Czaun, Miklos; Surya Prakash, G. K.; Olah, George A. (2012): Air as the renewable carbon source of the future: an overview of CO2 capture from the atmosphere. In: Energy Environ. Sci. 5 (7), pp. 7833-7853.
„The present article reviews methods developed for the capture of CO2 directly from the air as well as their advantages and drawbacks. While strong bases such as sodium hydroxide and potassium hydroxide could be used, their regeneration is energy intensive, requiring high temperatures.“
Chalecki, Elizabeth L.; Ferrari, Lisa L. (2012): More maple leaf, less CO 2. Canada and a global geo-engineering regime
Chalecki, Elizabeth L.; Ferrari, Lisa L. (2012): More maple leaf, less CO 2. Canada and a global geo-engineering regime. In: Canadian Foreign Policy Journal 18 (1), pp. 120–132.
„Finally, we examine Canada’s abilities and resources as a middle power to act as a foreign policy leader in the formation of a global geo-engineering regime.“
Moreno-Cruz, Juan B.; Keith, David W. (2012): Climate policy under uncertainty: a case for solar geoengineering
Moreno-Cruz, Juan B.; Keith, David W. (2012): Climate policy under uncertainty: a case for solar geoengineering. In: Climatic Change. DOI 10.1007/s10584-012-0487-4
This paper has been published as a working paper before. „We find that even modest reductions in uncertainty about the side-effects of SRM can reduce the overall costs of climate change in the order of 10%.“

Preston, Christopher J. (Hg.) (2012): Engineering the Climate: The Ethics of Solar Radiation Management: Lexington Books.
„This book, including essays by 13 experts in the field of ethics of geoengineering, is intended to go some distance towards providing that treatment.“

US Biochar Conference 2012
29.07.-01.08.2012, Sonoma State University/USA
„The 2012 US Biochar Conference is designed to advance our understanding of the economic, science and policy issues related to biochar as both an amendment for soils as well as an agent to sequester carbon.“
Conference presentation: Cliva Hamilton: The Philosophy of Geoengineering
Fro the IMPLICC symposium ‘The Atmospheric Science and Economics of Climate Engineering via Aerosol Injection’ held at the Max Planck Institute for Chemistry, Mainz, Germany, 14-16 May, 2012
Bellamy, Rob; et al. (2012): Appraising Geoengineering
Bellamy, Rob; Chilvers, Jason; Vaughan Naomi E.; Lenton, Timothy M. (2012): Appraising Geoengineering. In: Tyndall Centre for Climate Change Research – Working Paper (153), pp. 1–36.
Submitted and under review with WIREs Climate Change – „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.“
