In the last decade, solar geoengineering (solar radiation management, or SRM) has received increasing consideration as a potential means to reduce risks of anthropogenic climate change. Some ideas regarding SRM that have been proposed have receded after being appropriately scrutinized, while others have strengthened through testing and critique. This process has improved the understanding of SRM's potential and limitations. However, several claims are frequently made in the academic and popular… 

18 Politically relevant solar geoengineering scenarios

Solar geoengineering, also known as Solar Radiation Modification (SRM), has been proposed to alter Earth’s radiative balance to reduce the effects of anthropogenic climate change. SRM has been

Is solar geoengineering ungovernable? A critical assessment of governance challenges identified by the Intergovernmental Panel on Climate Change

Solar radiation modification (SRM) could greatly reduce climate change and associated risks. Yet it has not been well‐received by the climate change expert community. This is evident in the

The environmental impacts of anthropogenic climate change, from an increase in global temperatures melting polar ice caps to the generation of extreme weather events, appear to be happening even more

Solar geoengineering to reduce climate change: a review of governance proposals

Proposals to govern commercial actors, who could provide goods and services for solar geoengineering, focus on intellectual property policy and the review closes with suggested lines of future inquiry.

Solar geoengineering research on the U.S. policy agenda: when might its time come?

ABSTRACT Solar geoengineering (SG) may be a helpful tool to reduce harms from climate change, yet further research into its potential benefits and risks must occur prior to any implementation. So

This article presents a brief account of scientific research into solar geoengineering in India in the last decade. In recent years, solar geoengineering has been proposed as an option to ameliorate

Reflecting upon 10 years of geoengineering research: Introduction to the Crutzen + 10 special issue

Ten years ago, Nobel laureate Paul Crutzen called for research into the possibility of reflecting sunlight away from Earth by injecting sulfur particles into the stratosphere. Across academic

ABSTRACT Solar radiation management (SRM) – a form of geoengineering – creates a risk of ‘termination shock’. If SRM was to be stopped abruptly then temperatures could rise very rapidly with

This paper examines how notions of equity are being evoked by expert advocates of more research into solar geoengineering. We trace how specific understandings of equity figure centrally—although not

A Modest Defense of Geoengineering Research: a Case Study in the Cost of Learning

Recently, research into the possibilities of developing solar radiation management (SRM) and other geoengineering technologies has gained new momentum. Just last year, Cambridge University announced



A temporary, moderate and responsive scenario for solar geoengineering

The risks and benefits of solar geoengineering, or solar radiation management (SRM), depend on assumptions about its implementation. Claims that SRM will reduce precipitation, increase ocean

On the regulation of geoengineering

New evidence that the climate system may be especially sensitive to the build-up of greenhouse gases and that humans are doing a poor job of controlling their effluent has animated discussions around

Assessing the regional disparities in geoengineering impacts

Solar Radiation Management (SRM) Geoengineering may ameliorate many consequences of global warming but also has the potential to drive regional climates outside the envelope of greenhouse‐gas induced

The impact of geoengineering on vegetation in experiment G1 of the GeoMIP

Solar Radiation Management (SRM) has been proposed as a mean to partly counteract global warming. The Geoengineering Model Intercomparison Project (GeoMIP) has simulated the climate consequences of a

Geoengineering the Climate: Science, Governance and Uncertainty

Geoengineering, or the deliberate large-scale manipulation of the planetary environment to counteract anthropogenic climate change, has been suggested as a new potential tool for addressing climate

To avoid dangerous changes to the climate system, the global mean temperature must not rise more than 2 °C from the 19th century level. The German Advisory Council on Global Change recommends

Risks of Climate Engineering

By focusing on limiting warming, the debate creates a false sense of certainty and downplays the impacts of geoengineering solutions.

Transient climate–carbon simulations of planetary geoengineering

It is found that the climate system responds quickly to artificially reduced insolation; hence, there may be little cost to delaying the deployment of geoengineering strategies until such a time as “dangerous” climate change is imminent.

The Incredible Economics of Geoengineering

The focus of climate policy so far has been on reducing the accumulation of greenhouse gases. That approach, however, requires broad international cooperation and, being expensive, has been hindered

Albedo Enhancement by Stratospheric Sulfur Injections: A Contribution to Resolve a Policy Dilemma?

Fossil fuel burning releases about 25 Pg of CO2 per year into the atmosphere, which leads to global warming (Prentice et al., 2001). However, it also emits 55 Tg S as SO2 per year (Stern, 2005),
