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."

Winsberg, E. (2019): A modest defense of geoengineering research

Winsberg, Eric (2019): A modest defense of geoengineering research. [Preprint].

"This paper examines the ethics of geoengineering research--particular research regarding solar radiation management using stratospheric aerosols. It takes a broadly consequentialist approach. The goal is to estimate the expected utility of conducting the research itself."

Longreads: Holly Jean Buck: It’s Time To Talk About Solar Geoengineering

"We need to start talking about seemingly drastic approaches to the climate crisis, such as sun-dimming aerosols, right now — or we risk losing democratic control of the process."

MacMartin, Douglas G.; et al. (2019): Technical characteristics of a solar geoengineering deployment and implications for governance

MacMartin, Douglas G.; Irvine, Peter J.; Kravitz, Ben; Horton, Joshua B. (2019): Technical characteristics of a solar geoengineering deployment and implications for governance. In Climate Policy 22, pp. 1–15. DOI: 10.1080/14693062.2019.1668347.

"We examine the science of solar geoengineering in order to clarify the technical dimensions of decisions about deployment – both strategic and operational – and how these might influence governance considerations, while consciously refraining from making specific recommendations. The focus here is on a hypothetical deployment rather than governance of the research itself. We first consider the complexity surrounding the design of a deployment scheme, in particular the complicated and difficult decision of what its objective(s) would be, given that different choices for how to deploy will lead to different climate outcomes. Next, we discuss the on-going decisions across multiple timescales, from the sub-annual to the multi-decadal."

CNBC: This Bill Gates-funded chemical cloud could help stop global warming

"Bill Gates is backing the first high-altitude experiment of one radical approach called solar geoengineering. It’s meant to mimic the effects of a giant volcanic eruption."

Collomb, J.-D. (2019): US Conservative and Libertarian Experts and Solar Geoengineering: An Assessment

Collomb, Jean-Daniel (2019): US Conservative and Libertarian Experts and Solar Geoengineering: An Assessment. In: European journal of American studies (14-2). Online verfügbar unter http://journals.openedition.org/ejas/pdf/14717.

"The goal of this article is to review the various positions taken by free-market conservative and libertarian public policy experts regarding solar geoengineering. A quantitative analysis and a qualitative analysis of the online publications of ten major free-market think tanks are provided with a view to determining whether free-market conservative and libertarian experts are embracing solar geoengineering as a key solution to climate change."

The Verge: As a last resort, Andrew Yang proposes space mirrors to save the planet

"Presidential hopeful Andrew Yang has delivered a climate plan that fleshes out his dreams for a geoengineered world. According to his proposal, which was released on August 26th, it’ll take 20 years, $4.87 trillion, and maybe even space mirrors to prevent a climate catastrophe."
