Hopes&Fears: Why don't we just terraform Earth?

"Well, on Earth, geo-engineering is taken very seriously. As you may remember, there was a group up in British Columbia that tried to take geo-engineering into their own hands by dumping a lot of iron in an attempt to fertilize the ocean. It is certainly feasible, and, as some would argue, it's desirable."

Aaheim, Asbjørn; et al. (2015): An economic evaluation of solar radiation management

Aaheim, Asbjørn; Romstad, Bård; Wei, Taoyuan; Kristjánsson, Jón Egill; Muri, Helene; Niemeier, Ulrike; Schmidt, Hauke (2015): An economic evaluation of solar radiation management. In The Science of the Total Environment 532, pp. 61–69. DOI 10.1016/j.scitotenv.2015.05.106.

"This paper addresses the economic impacts of implementing two SRM technologies; stratospheric sulfur injection and marine cloud brightening. By the use of a computable general equilibrium model, we estimate the economic impacts of climatic responses based on the results from two earth system models, MPI-ESM and NorESM."

New American: Billionaire: $25M Prize to Solve Global Warming by Geoengineering

"Richard Branson (shown), chairman of Virgin Group Ltd., has offered a $25-million prize for the best solution for ending so-called global warming using geoengineering (also called climate engineering), which is the deliberate and large-scale intervention in the Earth’s climatic system."

Rayner, Steve (2015): To know or not to know? A not on ignorance as a rethorical resource in geoengineering debates

Rayner, Steve (2015): To know or not to know? A not on ignorance as a rethorical resource in geoengineering debates. In Matthias Gross, Linsey McGoey (Eds.): Routledge international handbook of ignorance studies. 1 Edition. Balsingstoke: Routledge (Routledge international handbooks), pp. 308–317.

Handbook with an article by Rayner. "The field is growing fast and this handbook reflects this interdisciplinary field of study by drawing contributions from economics, sociology, history, philosophy, cultural studies, anthropology, feminist studies, and related fields in order to serve as a seminal guide to the political, legal and social uses of ignorance in social and political life."

Wong, Pak-Hang (2015): Consenting to Geoengineering

Wong, Pak-Hang (2015): Consenting to Geoengineering. In Philos. Technol. DOI 10.1007/s13347-015-0203-1.

"This article offers a theoretical reflection on different conceptions of consent and their place(s) in geoengineering governance. More specifically, I discuss three models of consent, i.e. explicit consent, implied consent and hypothetical consent, and assess their applicability to geoengineering governance."

Washington Post: Climate engineering would cool down the planet — but it may not save West Antarctica

"That’s why a new study recently accepted in Geophysical Research Letters could be so significant. For it calls into question whether geoengineering — at least using sulfate aerosols — can actually save this ice sheet, which is already beginning to be destabilized in our warming world."

Blackstock, Jason J.; et al. (2015): Designing Procedural Mechanisms for the Governance of Solar Radiation Management Field Experiments

Blackstock, Jason J.; Craik, Neil; Doughty, Jack; Horton, Joshua B. (2015): Designing Procedural Mechanisms for the Governance of Solar Radiation Management Field Experiments. Workshop Report. Centre for International Governance Innovation (CIGI). Waterloo.

"This two-day workshop brought together 17 policy officials, physical scientists and governance scholars, predominantly
from the United States and Canada, to consider and evaluate governance mechanisms that may be useful for managing proposed solar radiation management (SRM) field experiments."

Renforth, P.; et al. (2015): The dissolution of olivine added to soil: Implications for enhanced weathering

Renforth, P.; Pogge von Strandmann, P.A.E.; Henderson, G. M. (2015): The dissolution of olivine added to soil: Implications for enhanced weathering. In Applied Geochemistry 61, pp. 109–118. DOI 10.1016/j.apgeochem.2015.05.016.

"Here we present results from laboratory flow-through dissolution experiments which seek to bridge this observational discrepancy by using columns of soil returned to the laboratory from a field site. We constrain the dissolution rate of olivine added to the top of one of these columns, while maintaining much of the complexity inherent in the soil environment."
