Gizmodo: Billionaires’ Favorite Climate Solution Is a Dangerous Distraction

"The prize is part of a growing movement by the billionaire class to make carbon dioxide removal, known as CDR in science and policy circles, a reality. But the narrative fit for a sci-fi movie obscures the fact that CDR comes with real issues as does the fact that a few incredibly wealthy (largely) men and industries are trying to define the scope of climate solutions."

Odoulami, Romaric C.; et al. (2020): Stratospheric Aerosol Geoengineering could lower future risk of ‘Day Zero’ level droughts in Cape Town

Odoulami, Romaric C.; New, Mark; Wolski, Piotr; Guillemet, Gregory; Pinto, Izidine; Lennard, Christopher et al. (2020): Stratospheric Aerosol Geoengineering could lower future risk of ‘Day Zero’ level droughts in Cape Town. In Environ. Res. Lett. 15 (12), p. 124007. DOI: 10.1088/1748-9326/abbf13.

"Here, we assess the potential for geoengineering using stratospheric aerosols injection (SAI) to offset the risk of 'Day Zero' level droughts in a high emission future climate using climate model simulations from the Stratospheric Aerosol Geoengineering Large Ensemble Project."

Fujiki, Atsushi (2021): Reconsidering Precautionary Attitudes and Sin of Omission for Emerging Technologies: Geoengineering and Gene Drive

Fujiki, Atsushi (2021): Reconsidering Precautionary Attitudes and Sin of Omission for Emerging Technologies: Geoengineering and Gene Drive. In Tsuyoshi Matsuda, Jonathan Wolff, Takashi Yanagawa (Eds.): Risks and Regulation of New Technologies. Singapore: Springer Singapore Pte. Limited (Kobe University Monograph Series in Social Science Research Ser), pp. 249–267.

"However, precautionary and preemptive attitudes may be also obstacles to decision making because they are used by both the advocates and opponents of these new fields. Therefore, when we examine “innovative emerging technologies that will have unquantifiable and unpredictable influences over a wide spatio-temporally range and produce catastrophic irreversible consequences in a worst-case scenario” from the viewpoint of precautionary attitudes, it is necessary to identify the situations and risks that we really want to avoid because the words “precautionary” and “omission” can have different meanings for different stakeholders."

Call for Submissions: Security Politics, Risk and Climate Geoengineering

Deadline: 19. January 2021

"In security terms, climate change is widely studied and debated and often understood as a threat or risk multiplier, including in emerging accounts of planetary, ecological or human security. However, security imaginaries of climate geoengineering are undeveloped and only now beginning to emerge."

Schneider, Tapio; et al. (2020): Solar geoengineering may not prevent strong warming from direct effects of CO2 on stratocumulus cloud cover

Schneider, Tapio; Kaul, Colleen M.; Pressel, Kyle G. (2020): Solar geoengineering may not prevent strong warming from direct effects of CO2 on stratocumulus cloud cover. In Proceedings of the National Academy of Sciences of the United States of America. DOI: 10.1073/pnas.2003730117.

"Solar geoengineering that manipulates the amount of sunlight Earth absorbs is increasingly discussed as an option to counter global warming. However, we demonstrate that solar geoengineering is not a fail-safe option to prevent global warming because it does not mitigate risks to the climate system that arise from direct effects of greenhouse gases on cloud cover"
