Ng, W. Y.; et al. (2020): Ranking negative emissions technologies under uncertainty

Ng, W. Y.; Low, C. X.; Putra, Z. A.; Aviso, K. B.; Promentilla, M.A.B.; Tan, R. R. (2020): Ranking negative emissions technologies under uncertainty. In Heliyon 6 (12), e05730. DOI: 10.1016/j.heliyon.2020.e05730.

"Given that there are multiple available NETs that need to be evaluated based on multiple criteria, there is a need for a systematic method for ranking and prioritizing them. Furthermore, the uncertainty in estimating the techno-economic performance levels of NETs is a major challenge. In this work, an integrated model of fuzzy analytical hierarchy process (AHP) and interval-extended Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) is proposed to address the multiple criteria, together with data uncertainties."

C2G Guest Post: 5 lessons from COVID-19 for solar geoengineering

"If the idea of suppressing temperature rise by injecting an aerosol into the sky leaves the realm of modelling and experiments, it will be thrust into a science-media-politics environment that operates in ways that are not currently anticipated—at least not in idealized modelling studies."

Call for Participation: Research on NETs survey

Deadline: 01. November 2020

"I am interested in your opinions on the role of negative emissions in climate policy, connected uncertainties, and possible implementation options. I seek views from a variety of people working on or engaging in policy discussions on negative emission technologies."

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."

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."
