Feder, Toni (2021): Should solar geoengineering be part of how humanity counters climate change?

Feder, Toni (2021): Should solar geoengineering be part of how humanity counters climate change? In Phys. Today 74 (6), pp. 22–26. DOI: 10.1063/PT.3.4768.

"Solar geoengineering research should be cautiously ramped up, says the US National Academies of Sciences, Engineering, and Medicine (NASEM) in a report released on 25 March. Tools to cool the planet cannot undo global warming, but they may avert some of its worst impacts."

Felgenhauer, Tyler; et al. (2021): Solar geoengineering research on the U.S. policy agenda: when might its time come?

Felgenhauer, Tyler; Horton, Joshua; Keith, David (2021): Solar geoengineering research on the U.S. policy agenda: when might its time come? In Environmental Politics, pp. 1–21. DOI: 10.1080/09644016.2021.1933763.

"We apply the Multiple Streams Approach analytical framework to explain why a U.S. federal SG research program has failed to materialize up to now, and to consider how one might emerge in the future. We argue that establishing a federal program will require the formation of an advocacy coalition within the political arena that is prepared to support such a policy objective."

Wagner, Gernot (2021): Geoengineering. The gamble

Wagner, Gernot (2021): Geoengineering. The gamble. Cambridge, UK, Medford, MA: Polity Press.

"In Geoengineering: the Gamble, climate economist Gernot Wagner provides a balanced take on the possible benefits and all-too-real risks. Despite those risks, he argues, geoengineering may only be a matter of time. Not if, but when."

Jebari, Joseph; et al. (2021): From Moral Hazard to Risk-Response Feedback

Jebari, Joseph; Andrews, Talbot M.; Aquila, Valentina; Beckage, Brian; Belaia, Mariia; Clifford, Maggie et al. (2021): From Moral Hazard to Risk-Response Feedback. In Climate Risk Management, p. 100324. DOI: 10.1016/j.crm.2021.100324.

"We argue that debates over “moral hazard” in response to carbon removal and geoengineering are unhelpful and misleading. We also propose an alternative framework for dealing with the tradeoffs that motivate the appeal to “moral hazard,” which we call “risk-response feedback.”"
