Fifteen Years of Controversy on Solar Geoengineering in the United States, Canada, the United Kingdom and Australia

open access: yesCahiers François Viète, 2020
This article provides an analysis of the academic controversy concerning research on solar geoengineering technologies in the United States, the United Kingdom, Canada, and Australia since 2006.

Solar geoengineering, uncertainty, and the price of carbon [PDF]

open access: yesJournal of Environmental Economics and Management, 2018
Abstract We consider the socially optimal use of solar geoengineering to manage climate change and its implications for carbon emissions abatement policy. We show that solar geoengineering is a substitute for emissions abatement; optimal policy includes less abatement, by up to eight percentage points, and has a lower carbon price, by up to fifteen ...

Climate tipping points and solar geoengineering [PDF]

open access: yesJournal of Economic Behavior & Organization, 2016
Abstract We study optimal climate policy in the presence of climate tipping points and solar geoengineering. Solar geoengineering reduces temperatures without reducing greenhouse gas emissions. Climate tipping points are irreversible and uncertain events that can alter the dynamics of the climate system.

A risk-based framework for assessing the effectiveness of stratospheric aerosol geoengineering. [PDF]

open access: yesPLoS ONE, 2014
Geoengineering by stratospheric aerosol injection has been proposed as a policy response to warming from human emissions of greenhouse gases, but it may produce unequal regional impacts. We present a simple, intuitive risk-based framework for classifying

Impact of solar geoengineering on temperature-attributable mortality. [PDF]

open access: yesProc Natl Acad Sci U S A
Decisions about solar geoengineering (SG) entail risk–risk tradeoffs between the direct risks of SG and SG’s ability to reduce climate risks. Quantitative comparisons between these risks are needed to inform public policy. We evaluate idealized SG’s effectiveness in reducing deaths from warming using two climate models and an econometric analysis of ...

Stratospheric solar geoengineering without ozone loss. [PDF]

open access: yesProc Natl Acad Sci U S A, 2016
Significance The combination of emissions cuts and solar geoengineering could reduce climate risks in ways that cannot be achieved by emissions cuts alone: It could keep Earth under the 1.5-degree mark agreed at Paris, and it might stop sea level rise this century. However, this promise comes with many risks.

Top lesson from COVID for solar geoengineering: Anticipatory research is needed

open access: yesFrontiers in Climate, 2022
This perspective article argues that anticipatory research into possible “emergency” response measures such as solar geoengineering will increase knowledge, and thus confidence, in any future decisions to either deploy or reject these technologies ...

Impacts of three types of solar geoengineering on the Atlantic Meridional Overturning Circulation [PDF]

open access: yesAtmospheric Chemistry and Physics, 2022
Climate models simulate lower rates of North Atlantic heat transport under greenhouse gas climates than at present due to a reduction in the strength of the Atlantic Meridional Overturning Circulation (AMOC).

Gravitationally bound geoengineering dust shade at the inner Lagrange point [PDF]

open access: yes, 2012
This paper presents a novel method of space-based geoengineering which uses the mass of a captured near Earth asteroid to gravitationally anchor a cloud of unprocessed dust in the vicinity of the L1 position to reduce the level of solar insolation at ...

Geoengineering: Basic science and ongoing research efforts in China

open access: yesAdvances in Climate Change Research, 2015
Geoengineering (also called climate engineering), which refers to large-scale intervention in the Earth's climate system to counteract greenhouse gas-induced warming, has been one of the most rapidly growing areas of climate research as a potential ...
