India Climate Dialogue: Promises and perils of a sunshade

"Solar radiation management is an extreme way to handle climate change and today nobody wants to do it; but if the world is forced to consider this geoengineering option seriously, how is it to be governed"

Matzner, Nils; Herrenbrück, Robert (2016): Simulating a Climate Engineering Crisis. Climate Politics Simulated by Students in Model United Nations

Matzner, Nils; Herrenbrück, Robert (2016): Simulating a Climate Engineering Crisis. Climate Politics Simulated by Students in Model United Nations. In Simulation & Gaming. DOI 10.1177/1046878116680513.

"This article aims both at simulating a plausible international scenario of negotiation over solar climate engineering deployment, and at utilizing the rules of Model United Nations (MUN) for collaborative learning in a university class. Furthermore, the article intends to provide a framework for simulations about CE that could easily be reproduced."

van Hemer, Mieke (2016): Speculative promise as a driver in climate engineering research. The case of Paul Crutzen’s back-of-the-envelope calculation on solar dimming with sulfate aerosols

van Hemer, Mieke (2016): Speculative promise as a driver in climate engineering research. The case of Paul Crutzen’s back-of-the-envelope calculation on solar dimming with sulfate aerosols. In Futures. DOI 10.1016/j.futures.2016.11.006.

"In this paper, I study the generative role of speculative promise in climate engineering research. My analysis operationalizes Alfred Nordmann’s call for a ‘forensics of wishing’, a variety of technology assessment which scrutinizes the politics of anticipation in technoscience. Using scientific articles and reports as primary sources I trace the uptake and contestation of bold claims made by atmospheric scientist Paul Crutzen a decade ago."

Irvine, Peter J.; et al. (2016): Towards a comprehensive climate impacts assessment of solar geoengineering

Irvine, Peter J.; Kravitz, Ben; Lawrence, Mark G.; Gerten, Dieter; Caminade, Cyril; Gosling, Simon N. et al. (2016): Towards a comprehensive climate impacts assessment of solar geoengineering. In Earth's Future. DOI 10.1002/2016EF000389.

"We suggest that a thorough assessment of the climate impacts of a range of scenarios of solar geoengineering deployment is needed and can build upon existing frameworks. However, solar geoengineering poses a novel challenge for climate impacts research as the manner of deployment could be tailored to pursue different objectives making possible a wide range of climate outcomes. We present a number of ideas for approaches to extend the survey of climate impacts beyond standard scenarios of solar geoengineering deployment to address this challenge."

FCEA Blog: Commentary: A response to Wil Burns: Common Misunderstandings About SRM Geoengineering

"We welcomed the response of Wil Burns to our recent article, “Five solar geoengineering tropes that have outstayed their welcome.” In our article, we cited five common but inaccurate claims about SRM. Burns responded to three of our rebuttals, concluding that our article “doesn’t wholly dispel many of the concerns outlined in the piece.” Ultimately, in his comments we have not found anything that refutes what we wrote. We remain convinced that the claims that we cited are unsupported by existing evidence, unlikely to occur, or greatly exaggerated."

Quaas, Johannes; et al. (2016): Regional climate engineering by radiation management: Prerequisites and prospects

Quaas, Johannes; Quaas, Martin F.; Boucher, Olivier; Rickels, Wilfried (2016): Regional climate engineering by radiation management: Prerequisites and prospects. In Earth’s Future. DOI 10.1002/2016EF000440.

"In this paper, we discuss the idea that RM can be differentiated and scaled in several dimensions with potential objectives being to influence a certain climate parameter in a specific region. Some short-lived climate forcers (e.g., tropospheric aerosols) exhibit strong geographical and temporal variability, potentially leading to limited- area climate responses. Marine cloud brightening and thinning or dissolution of cirrus clouds could be operated at a rather local scale."

Robock, Alan (2016): Albedo Enhancement by Stratospheric Sulfur Injections. More Research Needed

Robock, Alan (2016): Albedo Enhancement by Stratospheric Sulfur Injections. More Research Needed. In Earth's Future. DOI 10.1002/2016EF000407.

"More research is needed to better quantify the potential benefits and risks so that if society is tempted to implement geoengineering in the future it will be able to make an informed decision."

Harding, A.; Moreno-Cruz, Juan B. (2016): Solar geoengineering economics. From incredible to inevitable and half-way back

Harding, A.; Moreno-Cruz, Juan B. (2016): Solar geoengineering economics. From incredible to inevitable and half-way back. In Earth's Future. DOI 10.1002/2016EF000462.

"As our scientific understanding of the technologies evolve, so does the way economists think about them. In this paper, we document the evolution of economic thinking around these technologies since before [2006] until today and provide some fruitful areas for further research."

Visioni, Daniele; et al. (2016): Sulfate geoengineering. A review of the factors controlling the needed injection of sulfur dioxide

Visioni, Daniele; Pitari, Giovanni; Aquila, Valentina (2016): Sulfate geoengineering. A review of the factors controlling the needed injection of sulfur dioxide. In Atmos. Chem. Phys. Discuss., pp. 1–15. DOI 10.5194/acp-2016-985 .

"Sulfate geoengineering has been proposed as an affordable and climate-effective means for temporarily offset the warming produced by the increase of well mixed greenhouse gases (WMGHG). This climate engineering technique has been planned for a timeframe of a few decades needed to implement global inter-governmental measures needed to achieve stabilization of the atmospheric content of WMGHGs (CO2 in particular). The direct radiative effects of sulfur injection in the tropical lower stratosphere can be summarized as increasing shortwave scattering with consequent tropospheric cooling and increasing long- wave absorption with stratospheric warming."
