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."

MIT Technology Review: How green sand could capture billions of tons of carbon dioxide

"Scientists are taking a harder look at using carbon-capturing rocks to counteract climate change, but lots of uncertainties remain."

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."'

Video: Our Changing Climate: Could Geoengineering save us from climate change? (ft. @ClimateAdam)

"In this Our Changing Climate environmental video essay, I join forces with @ClimateAdam to look at silver bullet geoengineering solutions to climate change. Specifically, we look at how silver bullet geoengineering ideas can be appealing in theory, but in practice they often have a lot of ethical, economic, and social drawbacks."

Abatayo, Anna Lou; et al. (2020): Solar geoengineering may lead to excessive cooling and high strategic uncertainty

Abatayo, Anna Lou; Bosetti, Valentina; Casari, Marco; Ghidoni, Riccardo; Tavoni, Massimo (2020): Solar geoengineering may lead to excessive cooling and high strategic uncertainty. In PNAS. DOI: 10.1073/pnas.1916637117.

"We study the governance of solar geoengineering using a laboratory experiment in which participants engage in a public good-or-bad game. Results confirm that too much geoengineering can occur, leading to considerable economic losses and increased inequality. The experiment also highlights unforeseen governance risks associated with such technologies."

Kravitz, Ben; MacMartin, Douglas G. (2020): Uncertainty and the basis for confidence in solar geoengineering research

Kravitz, Ben; MacMartin, Douglas G. (2020): Uncertainty and the basis for confidence in solar geoengineering research. In Nat Rev Earth Environ 1 (1), pp. 64–75. DOI: 10.1038/s43017-019-0004-7.

"Using a risk-register framework, we illustrate key uncertainties, such as sub-grid-scale mixing or effects of stratospheric heating, investigations of which should be prioritized to transition the field to a mission-driven research agenda."

The Economist: Predicting the climatic future is riddled with uncertainty

"The world's climate scientists are charged with a difficult task: to create a crystal ball with which to skry a future that promises to be hotter than today. But exactly how much hotter depends on innumerable factors, both natural and human. Creating the crystal ball is thus a two-stage process. First, you have to build a simulacrum of how Earth’s climate works. Then, you try to perturb this simulacrum with plausible future human actions, to see what picture appears."

Rohr, T. (2019): Southern Ocean Iron Fertilization: An Argument Against Commercialization but for Continued Research Amidst Lingering Uncertainty

Rohr, Tyler (2019): "Southern Ocean Iron Fertilization: An Argument Against Commercialization but for Continued Research Amidst Lingering Uncertainty". Journal of Science Policy & Governance, Vol. 15, October 2019.

"I make that case that absent the appropriate oversight OIF activity on voluntary offset markets motivated by a reasonable market opportunity, the relative ease of deployment, and the perception of an ethical imperative, can, and will continue to, emerge. In turn, I argue that continued research is necessary to help constrain the public perception that voluntary markets depend on by further clarifying the risks, elaborating the challenges, and delegitimizing the promise of an iron bullet."

TEDx Talks: From Climate Shock to Geoengineering. Gernot Wagner

"Climate economist Dr. Gernot Wagner discusses how solar geoengineering can be a major solution to climate change. He considers Carbon taxes versus carbon taxes and talks about the issue of uncertainty as we find creative, market-based fixes for our warming planet."
