Global Priorities Project (2017): Existential Risk. Diplomacy and Governance

Global Priorities Project (2017): Existential Risk. Diplomacy and Governance.

"Geoengineering technologies like Solar Radiation Management have the potential to mitigate risks from climate change, while at the same time posing risks of their own. The current lack of international norms on acceptable research practices may well be holding back safe exploration of climate engineering options."

Keith, David W.; Irvine, Peter J. (2016): Solar geoengineering could substantially reduce climate risks—a research hypothesis for the next decade

Keith, David W.; Irvine, Peter J. (2016): Solar geoengineering could substantially reduce climate risks—a research hypothesis for the next decade. In Earth’s Future, n/a‐n/a. DOI 10.1002/2016EF000465.

"We offer a hypothesis that if SG were deployed to offset half of the increase in global-mean temperature from the date of deployment using a technology and deployment method chosen to approximate a reduction in the solar constant then, over the 21st Century, it would (a) substantially reduce the global aggregate risks of climate change, (b) without making any country worse off, and (c) with the aggregate risks from side-effects being small in comparison to the reduction in climate risks."

Mercury News: Commentary: Need portfolio approach to climate risk

"No one believes solar geoengineering is a climate change cure-all. And, like almost all innovations, it has known and unknown side effects. For one thing, it doesn't deal with ocean acidification. For another, we don't yet know enough about its effects on atmospheric ozone, for example, or on rainfall, or how it might help one region and hurt another."

FCEA Blog: Who May Geoengineer: Self-defense, Civil Disobedience, and Revolution (Part Two)

"[...] the paper is proceeding upon the basic normative idea that one cannot violate people’s rights in order to generate better social consequences and is then exploring whether risky geoengineering is consistent with or violates individual rights. In other words, “business as usual will be worse” is not good enough, on this view, to justify actions to intentionally violate people’s basic rights."

Arino, Yosuke; et al. (2016): Estimating option values of solar radiation management assuming that climate sensitivity is uncertain

Arino, Yosuke; Akimoto, Keigo; Sano, Fuminori; Homma, Takashi; Oda, Junichiro; Tomoda, Toshimasa (2016): Estimating option values of solar radiation management assuming that climate sensitivity is uncertain. In Proc Natl Acad Sci USA, p. 201520795–201520795. DOI 10.1073/pnas.1520795113.

"This paper presents one possible methodology for estimating option values of SRM assuming a fairly moderate scenario on SRM’s use compared with preceding literature, which would be helpful to examine realistic values of SRM for the society where social acceptability of SRM’s actual deployment is not high. Our results emphasize the near- to mid-term role of retaining SRM as a later risk-hedging option in the face of the uncertainty about climate sensitivity."

Mengis, Nadine; et al. (2016): Assessing climate impacts and risks of ocean albedo modification in the Arctic

Mengis, Nadine; Martin, T.; Keller, David P.; Oschlies, Andreas (2016): Assessing climate impacts and risks of ocean albedo modification in the Arctic. In J. Geophys. Res. Oceans. DOI 10.1002/2015JC011433.

"This study assesses climate impacts and risks of idealized Arctic Ocean albedo modification (AOAM), a proposed climate engineering method, during transient climate change simulations with varying representative concentration pathway (RCP) scenarios. We find no potential for reversing trends in all assessed Arctic climate metrics under increasing atmospheric CO2 concentrations."

JLL International: The Costs of Geoengineering in Manipulating Climate Change in the Unforeseen Future

"This examination serves to analyze the use of carbon dioxide removal and solar radiation management as two methods of alleviating climate change. This analysis will feature how successful existing technologies are at handling climate change as well as identifying what benefits and detriments each technology has introduced us to the world."

McCormack, Caitlin G.; et al. (2016): Key impacts of climate engineering on biodiversity and ecosystems, with priorities for future research

McCormack, Caitlin G.; Born, Wanda; Irvine, Peter J.; Achterberg, Eric P.; Amano, Tatsuya; Ardron, Jeff et al. (2016): Key impacts of climate engineering on biodiversity and ecosystems, with priorities for future research. In Journal of Integrative Environmental Sciences, pp. 1–26. DOI 10.1080/1943815X.2016.1159578.

"A literature review was carried out to identify details of the potential ecological effects of climate engineering techniques. A group of biodiversity and environmental change researchers then employed a modified Delphi expert consultation technique to evaluate this evidence and prioritize the effects based on the relative importance of, and scientific understanding about, their biodiversity and ecosystem consequences."
