Sovacool, Benjamin K. (2021): Reckless or righteous? Reviewing the sociotechnical benefits and risks of climate change geoengineering

Sovacool, Benjamin K. (2021): Reckless or righteous? Reviewing the sociotechnical benefits and risks of climate change geoengineering. In Energy Strategy Reviews 35, p. 100656. DOI: 10.1016/j.esr.2021.100656.

„[T]his study reviews and summarizes a large number of geoengineering assessments published over the past decade to document prospective benefits, but also reveal potential risks. It aims to provide a comprehensive evidence base on GGR and SRM technologies that is rigorous, timely, and interdisciplinary.“

The Guardian: Some say we can ‘solar-engineer’ ourselves out of the climate crisis. Don’t buy it

„So-called “solar geoengineering” doesn’t actually modify the sun itself. Instead, it reduces incoming sunlight by other means, such as putting chemicals in the atmosphere that reflect sunlight to space. It addresses a symptom of global heating, rather than the root cause, which is human-caused increase in the atmosphere’s burden of carbon dioxide.“

Creutzig, Felix; et al. (2021): Considering sustainability thresholds for BECCS in IPCC and biodiversity assessments

Creutzig, Felix; Erb, Karl‐Heinz; Haberl, Helmut; Hof, Christian; Hunsberger, Carol; Roe, Stephanie (2021): Considering sustainability thresholds for BECCS in IPCC and biodiversity assessments. In GCB Bioenergy 13 (4), pp. 510–515. DOI: 10.1111/gcbb.12798.

„Here, we contrast insights from these reports with other recent literature and demonstrate that BECCS bears additional risks for biodiversity, livelihoods, and intertemporal carbon balances.“

Video: Rolling Stone: How Dangerous Is Solar Geoengineering? | The Climate Debates

„We discuss some of the central issues: Is the climate crisis so far gone that we need to consider risky ideas like solar engineering? Is solar engineering a hubristic dream of techno-elitists or the best tool we have to reduce the impacts of a warming climate for millions of people in the developing world? Who would be the winners and losers in a geoengineered world?“

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[nbsp]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.“
