Gardiner, Stephen M. (2013): Why geoengineering is not a ‘global public good’, and why it is ethically misleading to frame it as one

Gardiner, Stephen M. (2013): Why geoengineering is not a ‘global public good’, and why it is ethically misleading to frame it as one. In: Climatic Change. DOI 10.1007/s10584-013-0764-x

"This paper argues that the paradigm example of geoengineering—stratospheric sulfate injection (hereafter ‘SSI’)—does not fit the canonical technical definition of a global public good, and that more relaxed versions are unhelpful."

SciDev: Concerns grow over effects of solar geoengineering

Media response to Bony; et al. (2013). "The latest studies on solar geoengineering to tackle climate change are reinforcing the case for a global governance system and further study before deployment, as they show that the approach may have little effect on preventing rainfall changes in the tropics — and may even lead to widespread drought in Africa."

Jaffe, R.; et al. (2013): Global Charcoal Mobilization from Soils via Dissolution and Riverine Transport to the Oceans

Jaffe, R.; Ding, Y.; Niggemann, J.; Vahatalo, A. V.; Stubbins, A.; Spencer, R. G. M. et al. (2013): Global Charcoal Mobilization from Soils via Dissolution and Riverine Transport to the Oceans. In: Science 340 (6130), pp. 345–347.

Related to biochar. "We have quantified dissolution products of charcoal in a wide range of rivers worldwide and show that globally, a major portion of the annual charcoal production is lost from soils via dissolution and subsequent transport to the ocean."

Vuuren, Detlef P.; et al. (2013): The role of negative CO2 emissions for reaching 2 °C—insights from integrated assessment modelling. In: Climatic Change.

Vuuren, Detlef P.; Deetman, Sebastiaan; Vliet, Jasper; Berg, Maarten; Ruijven, Bas J.; Koelbl, Barbara (2013): The role of negative CO2 emissions for reaching 2 °C—insights from integrated assessment modelling. In: Climatic Change. DOI 10.1007/s10584-012-0680-5

"Given the importance and the uncertainty concerning BECCS [bio-energy with carbon capture and storage], we stress the importance of near-term assessments of its availability as today’s decisions has important consequences for climate change mitigation in the long run."

Kriegler, Elmar; et al. (2013): Is atmospheric carbon dioxide removal a game changer for climate change mitigation?

Kriegler, Elmar; Edenhofer, Ottmar; Reuster, Lena; Luderer, Gunnar; Klein, David (2013): Is atmospheric carbon dioxide removal a game changer for climate change mitigation? In: Climatic Change. DOI 10.1007/s10584-012-0681-4

"The ability to directly remove carbon dioxide from the atmosphere allows the decoupling of emissions and emissions control in space and time. We ask the question whether this unique feature of carbon dioxide removal technologies fundamentally alters the dynamics of climate mitigation pathways."
