Global Policy Journal: Could Climate Interventions Slow the Melting of the Cryosphere?

"The ice sheets, sea ice and permafrost provide little direct economic benefit to nation states, despite their importance for Arctic indigenous peoples. But they do provide extremely important features that enable the present climate to operate as humankind has grown used to."

Moore, John C.; et al. (2020): Targeted Geoengineering: Local Interventions with Global Implications

Moore, John C.; Mettiäinen, Ilona; Wolovick, Michael; Zhao, Liyun; Gladstone, Rupert; Chen, Ying et al. (2020): Targeted Geoengineering: Local Interventions with Global Implications. In Glob Policy. DOI: 10.1111/1758-5899.12867.

"Targeted geoengineering aims to tackle a global scale impact of climate warming by addressing local or regional systemic interventions. We consider three examples: conserving the West Antarctic ice sheet by limiting rates of ice discharge or increasing snow accumulation, thereby reducing global sea level rise; transforming the Arctic permafrost zone into steppe grassland; raising the albedo of Arctic sea ice."

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"

Nelson, John P.; et al. (2020): Assessing solar geoengineering research funders: Insights from two US public deliberations

Nelson, John P.; Kaplan, Leah; Tomblin, David (2020): Assessing solar geoengineering research funders: Insights from two US public deliberations. In The Anthropocene Review, 205301962096484. DOI: 10.1177/2053019620964845.

"For both normative and pragmatic reasons, actors interested in SRM research and implementation would do well to attend to public preferences and concerns regarding SRM work. But despite growing literature treating public perspectives on SRM governance, little is known about public perceptions or preferences regarding potential SRM research funders. Specific research funders could significantly affect both the varieties, scales, and aims of research performed and public responses to SRM research. Drawing from two deliberative public forums on SRM research involving 171 participants in total, this paper begins to fill this gap in the literature."

Horton, Joshua B.; et al. (2020): Parametric Insurance for Solar Geoengineering: Insights from the Pacific Catastrophe Risk Assessment and Financing Initiative

Horton, Joshua B.; Lefale, Penehuro; Keith, David (2020): Parametric Insurance for Solar Geoengineering: Insights from the Pacific Catastrophe Risk Assessment and Financing Initiative. In Global Policy. DOI: 10.1111/1758-5899.12864.

"Parametric insurance, which delivers payouts when specific physical indices (such as wind speed) cross predefined thresholds, was recently proposed by two of us as a compensation mechanism for SG with the potential to ease disagreements about the technology and to facilitate cooperative deployment; we refer to this proposal as reduced‐rate climate risk insurance for solar geoengineering, or ‘RCG’. Here we probe the plausibility of RCG by exploring the Pacific Catastrophe Risk Assessment and Financing Initiative (PCRAFI), a sovereign risk pool providing parametric insurance coverage against tropical cyclones and earthquakes/tsunamis to Pacific island countries since 2013."

Corbett, Charles R. (2020): "Extraordinary" and "Highly Controversial": Federal Research of Solar Geoengineering Under NEPA

Corbett, Charles R. (2020): "Extraordinary" and "Highly Controversial": Federal Research of Solar Geoengineering Under NEPA. (September 21, 2020). Northwestern University Law Review Online (forthcoming), Available at SSRN: https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3696942.

"This Essay argues that NOAA should use its discretion to conduct a programmatic environmental assessment under the National Environmental Policy Act (“NEPA”) as an initial step in complying with Congress’s mandate. Federal research into solar geoengineering is an extraordinary and highly controversial policy. The agency should carefully consider the environmental, social, and political impacts that may come with this undertaking. Further, the public deserves an opportunity to weigh in on the matter and to be appraised of its risks."

Call for Submissions: Special Issue "Resolving uncertainties in solar geoengineering through multi-model and large-ensemble simulations" (ACP/ESD inter-journal SI)

Deadline: 31. July 2022

"To capture the interrelated research amongst these projects, the special issue is set up jointly between Atmospheric Chemistry and Physicsand Earth System Dynamics. In ACP, we invite papers that emphasize process-level understanding and stratospheric dynamics; in ESD, submissions on Earth system effects, feedbacks, and impacts (like agriculture or ecosystem responses) are invited."

C2G: Guest post: Can solar geoengineering be democratically governed?

"Some commentators argue that the potential use of solar geoengineering would pose serious challenges to democratic forms of government and governance. At the extreme, they have argued that solar geoengineering and democracy would be simply incompatible."

Video: Clive Elsworth: Iron Salt Aerosol Presentation

"The presentation will briefly:

  • make the urgent case for Negative Emission Technologies,
  • explain how methane removal is the low hanging fruit,
  • explain how a very diffuse ISA application over a wide area of iron-poor ocean would additionally safely induce a continuous, climate-relevant absorption of CO2."
