Manoussi, Vassiliki; Xepapadeas, Anastasios (2021): Cooperation and Competition in Climate Change Policies

Manoussi, Vassiliki; Xepapadeas, Anastasios (2021): Cooperation and Competition in Climate Change Policies. Mitigation and Climate Engineering when Countries are Asymmetric. In Environ Resource Econ. DOI: 10.1007/s10640-015-9956-3.

"Solar Radiation Management (SRM) is regarded as a tool to potentially counteract global warming by increasing planetary albedo. Even though it has shown effective results in offsetting global surface temperature, one of its main limits lies in the persistence of major regional anomalies, for both surface temperature and precipitation. Here, using the Globally Resolved Energy Balance (GREB) model, we present experiments designed to completely offset global and regional surface temperature response due to CO2 forcing."

Yale Environment 360: In the New UN Climate Report, a Better Understanding of Solar Geoengineering

"The latest report from the UN Intergovernmental Panel on Climate Change offers not only a clearer view of the causes and consequences of global warming, but also a better understanding of some extreme and untested solutions to the climate crisis, including solar geoengineering — the process of modifying clouds or spraying tiny reflective particles into the upper atmosphere to block a portion of the sun’s light, thereby cooling the planet, Reuters reported."

Global Policy: Solar Geoengineering at a Standstill?

"Joshua B. Horton argues that developing countries have the most to gain and to lose from resolving the impasse stalling global governance for geoengineering."

Bodansky, Daniel; Parker, Andy (2021): Research on Solar Climate Intervention Is the Best Defense Against Moral Hazard

Bodansky, Daniel; Parker, Andy (2021): Research on Solar Climate Intervention Is the Best Defense Against Moral Hazard. In Issues in Science and Technology 37 (4), pp. 19–21. Available online at https://issues.org/geoengineering-solar-intervention-climate-moral-hazard/, checked on 8/9/2021.

"As concerns about global warming mount and international efforts to address it lag, should public policy be encouraging or inhibiting research on technologies to reflect sunlight away from the earth? If efforts to limit emissions prove inadequate, solar climate intervention could be the only means of averting catastrophic harms. We need to understand its feasibility, safety, and costs, and that requires more research. "

Hoffmann, Fabian; Feingold, Graham (2021): Cloud Microphysical Implications for Marine Cloud Brightening: The Importance of the Seeded Particle Size Distribution

Hoffmann, Fabian; Feingold, Graham (2021): Cloud Microphysical Implications for Marine Cloud Brightening: The Importance of the Seeded Particle Size Distribution. In Journal of the Atmospheric Sciences. DOI: 10.1175/JAS-D-21-0077.1.

"In this study, we apply a highly detailed Lagrangian cloud model, coupled to an idealized parcel model as well as a full three-dimensional large-eddy simulation model, to show that the choice of seeded particle size distribution is crucial to the success of MCB, and that its efficacy can be significantly reduced by undesirable microphysical processes."

Podcast: Daniele Visioni and Gideon Futerman discuss the Event Solar Geoengineering: Warnings from Scientists, Indigenous Peoples, Youth, and Climate Activists

"His research is currently focused on studying Sulfate Geoengineering, a form of climate engineering that aims to partially, temporarily, offset the effects of climate change by means of injecting sulfate precursors in the stratosphere in order to reflect a small part of the incoming solar radiation and thus reduce global temperatures."

Pasek, Anne; et al. (2021): Reflections on a hypothetical decentralized grassroots deployment solar geoengineering scenario

Pasek, Anne; Morrow, David; Lee, Walker; Felgenhauer, Tyler (2021): Reflections on a hypothetical decentralized grassroots deployment solar geoengineering scenario. In Futures, p. 102811. DOI: 10.1016/j.futures.2021.102811.

"This thought experiment—the subject of a scenario exercise at the Sixth International Geoengineering Governance Summer School—produced a range of critical reflections on international responses to such grassroots deployment as participant teams developed and critiqued governance proposals."
