Progressive International: Holly Jean Buck: How to Decolonize the Atmosphere

"But discussion of carbon removal approaches must not be merely technical, but explicitly political. There are two reasons for this. First, the default approach to carbon removal under existing power structures both (a) risks further harm to frontline communities and ecosystems; and (b) probably won’t remove climate-significant amounts of carbon."

Low, Sean; Honegger, Matthias (2020): A Precautionary Assessment of Systemic Projections and Promises From Sunlight Reflection and Carbon Removal Modeling

Low, Sean; Honegger, Matthias (2020): A Precautionary Assessment of Systemic Projections and Promises From Sunlight Reflection and Carbon Removal Modeling. In Risk analysis : an official publication of the Society for Risk Analysis. DOI: 10.1111/risa.13565.

"We describe how evolving modeling practices are trending toward optimized and “best‐case” projections —portraying deployment schemes that create both technically slanted and politically sanitized profiles of risk, as well as ideal objectives for CDR and SRM as mitigation‐enhancing, time‐buying mechanisms for carbon transitions or vulnerable populations."

McKinnon, Catriona (2020): The Panglossian politics of the geoclique

McKinnon, Catriona (2020): The Panglossian politics of the geoclique. In Critical Review of International Social and Political Philosophy 23 (5), pp. 584–599. DOI: 10.1080/13698230.2020.1694216.

"Two prominent geoengineering researchers have recently argued that the risk of termination shock could be minimised through the adoption of ‘relatively simple’ policies. This paper shows their arguments to be premised on heroically optimistic assumptions about the prospects for global cooperation and sustained trust in an SRM deployment scenario. The paper argues that worst-case scenarios are the right place to start in thinking about the governance of SRM."

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."

Florin, Marie-Valentine; et al. (2020): lnternational governance issues on climate engineering Information for policymakers

Florin, Marie-Valentine; Rouse, Paul; Hubert, Anna-Maria; Honegger, Matthias; Reynolds, Jesse (2020): lnternational governance issues on climate engineering Information for policymakers. EPFL International Risk Governance Center (IRGC). Lausanne.

"Driven by questions and needs from the international policymaking community to better understand the potential benefits as well as opportunities, risks, uncertainties and other challenges of CDR and SRM, at both technical and governance levels, this report reviews and compares technologies and their potential contributions, costs, risks, uncertainties, before surveying the current legal and institutional landscape of governance regarding climate engineering."

Sapinski, J. P.; et al. (2020): Has it come to this? The promises and perils of geoengineering on the brink

Sapinski, J. P.; Buck, Holly Jean; Malm, Andreas (Eds.) (2020): Has it come to this? The promises and perils of geoengineering on the brink. New Brunswick, Camden: Rutgers University Press (Nature, society, and culture).

"How did we get into this situation where the most extreme path now seems a plausible development? Is it an accurate representation of where we are at? Who is this “we” who is talking? What options make it onto the table? Which are left out? Whom does geoengineering serve? Why is the ensemble of projects that goes by that name so salient, even though the community of researchers and advocates is remarkably small? These are some of the questions that the thinkers contributing to this volume are exploring from perspectives ranging from sociology and geography to ethics and indigenous studies."

Phys.org: Reflecting sunlight to cool the planet will cause other global changes

 

'"About half the world's population lives in the extratropical regions where storm tracks dominate weather," says Charles Gertler, a graduate student in MIT's Department of Earth, Atmospheric and Planetary Sciences (EAPS). "Our results show that solar geoengineering will not simply reverse climate change. Instead, it has the potential itself to induce novel changes in climate."'
