Grisé, Michelle; et al. (2021): Climate Control: International Legal Mechanisms for Managing the Geopolitical Risks of Geoengineering

Grisé, Michelle; Yonekura, Emmi; Blake, Jonathan S.; Desmet, David; Garg, Anusree; Preston, Benjamin Lee (2021): Climate Control: International Legal Mechanisms for Managing the Geopolitical Risks of Geoengineering. RAND Corporation.

"In this Perspective, the authors review the state of different geoengineering technologies, highlighting differences in technological development stage, price, time scales, and potential secondary effects. They discuss the geopolitical risks that may be introduced by geoengineering implementation. Given the many serious risks that geoengineering poses, they conclude by examining whether existing international governance mechanisms manage the geopolitical risks associated with geoengineering."

Bas, Muhammet A.; Mahajan, Aseem (2020): Contesting the climate

Bas, Muhammet A.; Mahajan, Aseem (2020): Contesting the climate. In Climatic Change. DOI: 10.1007/s10584-020-02758-7.

"We find that when countries’ temperature preferences diverge, applications of geoengineering and countergeoengineering can be highly wasteful due to deployment in opposite directions."

Lovenduski, N. S.; et al. (2020): The Potential Impact of Nuclear Conflict on Ocean Acidification

Lovenduski, Nicole S., Cheryl S. Harrison, Holly Olivarez, Charles G. Bardeen, Owen B. Toon, Joshua Coupe, Alan Robock, Tyler Rohr, and Samantha Stevenson (2020): The Potential Impact of Nuclear Conflict on Ocean Acidification. Geophysical Research Letters 47 (3). https://doi.org/10.1029/2019gl086246.

"We demonstrate that the global cooling resulting from a range of nuclear conflict scenarios would temporarily increase the pH in the surface ocean by up to 0.06 units over a 5‐year period, briefly alleviating the decline in pH associated with ocean acidification."

Samoaobserver: Climate Engineering and game changers for international climate policy

"In his response to my opinion piece “Climate engineering is the potential game changer we need to confront” published on October 18, 2018, posted online, October 23, 2018, Fiu Mataese invites me to “agree to disagree” on our views on geoengineering."

Nicholson, Simon; et al. (2017): Solar radiation management. A proposal for immediate polycentric governance

Nicholson, Simon; Jinnah, Sikina; Gillespie, Alexander (2017): Solar radiation management. A proposal for immediate polycentric governance. In Climate Policy 21 (1), pp. 1–13. DOI: 10.1080/14693062.2017.1400944.

"Specifically, we build from existing literature to argue that SRM governance must simultaneously: guard against the risks of uncontrolled SRM development; enable potentially valuable research; build legitimacy for research and any future policy through broad public engagement and ensure that SRM is only considered as one part of a broader mitigation agenda. We propose three interventions to work towards those objectives in the near term by: developing a transparency mechanism for research; creating a global forum for public engagement and including consideration of SRM in the global stocktake under the Paris Agreement."

Corry, Olaf (2017): The international politics of geoengineering. The feasibility of Plan B for tackling climate change

Corry, Olaf (2017): The international politics of geoengineering. The feasibility of Plan B for tackling climate change. In Security Dialogue 48 (4), pp. 297–315. DOI: 10.1177/0967010617704142.

"This article puts forward what it calls the ‘security hazard’ and argues that this could be a crucial factor in determining whether a technology is able, ultimately, to reduce climate risks. Ideas about global governance of geoengineering rely on heroic assumptions about state rationality and a generally pacific international system. Moreover, if in a climate engineered world weather events become something certain states can be made directly responsible for, this may also negatively affect prospects for ‘Plan A’, i.e. an effective global agreement on mitigation."

Smit, Erika C. (2015): Geoengineering. Issues of Accountability in International Law

Smit, Erika C. (2015): Geoengineering. Issues of Accountability in International Law. In: Nevada Law Journal 15 (2), S. 1060–1089.

"As this note shows through congressional hearings, newspaper articles, and international agreements, geoengineering and weather modification have been lingering matters in international law for several decades and will continue to be reviewed, researched, and developed in the years to come. This note examines how international law can provide legal accountability for geoengineering in the event of a catastrophic accident."
