Morrow, David R. (2014): Ethical aspects of the mitigation obstruction argument against climate engineering research

Morrow, David R. (2014): Ethical aspects of the mitigation obstruction argument against climate engineering research. In Philosophical Transactions of the Royal Society 372 (2031). DOI 10.1098/rsta.2014.0062.

"Why would it be a bad thing if climate engineering research obstructed mitigation? If climate engineering promises to be effective enough, it might justify some reduction in mitigation. Climate policy portfolios involving sufficiently large or poorly planned reductions in mitigation, however, could lead to an outcome that would be worse than the portfolio that would be chosen in the absence of further climate engineering research."

Niemeier, U.; et al. (2013): Solar irradiance reduction via climate engineering - Impact of different techniques on the energy balance and the hydrological cycle.

Niemeier, U.; Schmidt, H.; Alterskjaer, K.; Kristjánsson, J. E. (2013): Solar irradiance reduction via climate engineering - Impact of different techniques on the energy balance and the hydrological cycle. In J. Geophys. Res. Atmos., pp. n/a. DOI 10.1002/2013JD020445

"Different techniques of solar radiation management (SRM) have been suggested to counteract global warming, among them the injection of sulfur into the stratosphere, mirrors in space, and marine cloud brightening through artificial emissions of sea salt. This study focuses on to what extent climate impacts of these three methods would be different."

e! Science News: Cooling ocean temperature could buy more time for coral reefs

Media response to Couce (2013). "Limiting the amount of warming experienced by the world's oceans in the future could buy some time for tropical coral reefs, say researchers from the University of Bristol."

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."
