Lockley, A. (2019): Distributed Governance of Solar Radiation Management Geoengineering: A Possible Solution to SRM’s ‘Free-Driver’ Problem?

Lockley, Andrew. 2019. “Distributed Governance of Solar Radiation Management Geoengineering: A Possible Solution to SRM’s ‘Free-Driver’ Problem?” Frontiers of Engineering Management, October. https://doi.org/10.1007/s42524-019-0055-y.

‌"We propose a novel distributed governance model of consensually-constrained unilateralism: Countries’ authority is limited to each state’s fraction of the maximum realistic intervention (e.g., pre-industrial temperature). We suggest a division of authority based on historical emissions (Rocha et al., 2015)—noting alternatives (e.g., population). To aid understanding, we offer an analogue: An over-heated train carriage, with passenger-controlled windows. We subsequently discuss the likely complexities, notably Coasian side-payments. Finally, we suggest further research: Algebraic, bot and human modeling; and observational studies."

Schroeder, C.; et al (2019): “Stratospheric Aerosol Injection as a Deep Reinforcement Learning Problem

Schroeder, Christian, and Thomas Hornigold. 2019. “Stratospheric Aerosol Injection as a Deep Reinforcement Learning Problem.” ArXiv.Org. 2019. https://arxiv.org/abs/1905.07366v1.

‌"We suggest treating SAI as a high-dimensional control problem, with policies trained according to a context-sensitive reward function within the Deep Reinforcement Learning (DRL) paradigm. In order to facilitate training in simulation, we suggest to emulate HadCM3, a widely used General Circulation Model, using deep learning techniques. We believe this is the first application of DRL to the climate sciences."

Kaplan, Leah; et al. (2019): Cooling a Warming Planet? Public Forums on limate Intervention Research

Kaplan, Leah; Nelson, John; Tomblin, David; Farooque, Mahmud; Lloyd, Jason; Neff, Mark et al. (2019): "Cooling a Warming Planet? Public Forums on limate Intervention Research." ASU Consortium for Science, Policy & Outcomes. Washington, DC. Available online at https://cspo.org/wp-content/uploads/2019/10/SRM_book_EPUB.pdf.

"CSPO and its partners, including the Expert and Citizen Assessment of Science and Technology (ECAST) network and the ASU-based PlanetWorks initiative, used participatory technology assessment (pTA), a method of determining public values and opinions to help inform up-stream decision-making, as an instrument to elicit views on the governance of SRM research. After an iterative design process with both technical experts and members of the lay public, CSPO hosted two day-long public deliberations on the governance of SRM research in Boston and Phoenix in September 2018."

Fiekowsky, Peter; et al. (2019): Climate Restoration: Solutions to the Greatest Threat Facing Humanity and Nature Today. The Foundation for Climate Restoration, September 2019. White Paper.

Fiekowsky, Peter; Douglis, Carole; Lee, Susan (2019): Climate Restoration: Solutions to the Greatest Threat Facing Humanity and Nature Today. The Foundation for Climate Restoration, September 2019. White Paper. Available online at https://foundationforclimaterestoration.org/wp-content/uploads/2019/09/20190916b_f4cr4_white-paper.pdf.

"The purpose of this paper is to show that we do not in fact need to leave dangerous, unprecedented conditions to our progeny. We have the technology and the financing, now, to reclaim the climate of over a century ago. What we need is the commitment to do so."

Yahoo: Harvard Faculty Ye Tao presents a Solution to the Climate Change Crisis at NanoScientific Symposium Nov 19, 2019

"In his presentation at NanoScientific Symposium at SUNY on Nov.19, 2019 titled Mirrors for Earth's Energy Rebalancing (MEER:ReflEction): Resource-driven engineering for leveraging Earth's chemistries to immediately offer remediation, Dr. Tao will discuss how effectively addressing the complex issue mandates simultaneously solving five individually challenging problems: (1) planetary overheating, (2) energy production, (3) ocean acidification, (4) positive climate feedbacks, and (5) food security."

London NERC DTP: PhD Project: The aridity, drought and biodiversity impacts of Solar Geoengineering

"In this PhD project, you will evaluate the hydrological impacts of stratospheric aerosol geoengineering on society and ecosystems. You will evaluate drought and aridity changes from a range of different perspectives: meteorological (how much precipitation is there?), hydrological (how much river run off is there?), and agro-ecological (how is vegetation faring?). You will assess these hydrological changes using output from the latest generation of climate models and in offline land model simulations."

Blog post by Prakash Kashwan on the Forum for CE Assessment: Should geoengineering be considered a global public good?

"“Geoengineering to be regulated as a public good” – this is the first among the five key “Oxford Principles” for the governance of geoengineering. However, ‘public goods’ means very different things to different audiences. Climate scientists, social scientists, economists, the general public, policymakers: all may carry quite different understandings of what it means to look at something as a public good."

C2G: Evidence Brief: Governing Marine Carbon Dioxide Removal and Solar Radiation Modification

"This briefing summarises the latest evidence around Carbon Dioxide Removal (CDR) and Solar Radiation Modification (SRM) techniques related to the marine environment. It describes a range of techniques currently under consideration, exploring their technical readiness, current research, applicable governance frameworks, and other socio-political considerations. It also provides an overview of key instruments relevant for the governance of marine CDR and SRM."

C2G: Policy Brief: Governing Marine Solar Radiation Management

"Marine SRM techniques are for the most part theoretical, but if ever deployed, some could create large and potentially long-term risks and governance challenges. We do not yet know enough about the risks, costs and potential benefits, or governance requirements, to understand if marine SRM techniques could be viable, or – if so – whether, when or how to deploy them."
