Anthropogenic greenhouse gas emissions are changing the Earth’s climate and impose substantial risks for current and future generations. What are scientifically sound, economically viable, and ethically defendable strategies to manage these climate risks? Ratified international agreements call for a reduction of greenhouse gas emissions to avoid dangerous anthropogenic interference with the climate system. Recent proposals, however, call for a different approach: to geoengineer climate by… 

The potential for climate engineering with stratospheric sulfate aerosol injections to reduce climate injustice

ABSTRACT Climate engineering with stratospheric sulfate aerosol injections (SSAI) has the potential to reduce risks of injustice related to anthropogenic emissions of greenhouse gases. Relying on

An overview of the Earth system science of solar geoengineering

Solar geoengineering has been proposed as a means to cool the Earth by increasing the reflection of sunlight back to space, for example, by injecting reflective aerosol particles (or their

Climate Engineering: Economic Considerations and Research Challenges

Climate engineering measures are designed to either reduce atmospheric carbon concentration (by growing trees or spreading iron in the ocean, for example) or directly influence the radiation reaching


Global efforts made by the international community to reduce anthropogenic greenhouse gas emissions have not been successful yet to adequately address the challenge posed by climate change. On the

Climate engineering and climate tipping-point scenarios

Many scientists fear that anthropogenic emissions of greenhouse gases have set the Earth on a path of significant, possibly catastrophic, changes. This includes the possibility of exceeding

China and the blunt temptations of geo-engineering: the role of solar radiation management in China's strategic response to climate change

Abstract Amid growing alarm over the rising atmospheric concentration of greenhouse gases, increasing attention is being given to ‘geo-engineering’ technologies that could counteract some of the

Solar Geoengineering, Uncertainty, and the Price of Carbon

Cost-Risk Trade-Off of Mitigation and Solar Geoengineering: Considering Regional Disparities Under Probabilistic Climate Sensitivity

Solar geoengineering (SGE) constitutes a viable option to ameliorate anthropogenic temperature rise. However, it does not simultaneously compensate for anthropogenic changes in further climate



Economically optimal risk reduction strategies in the face of uncertain climate thresholds

Anthropogenic greenhouse gas emissions may trigger climate threshold responses, such as a collapse of the North Atlantic meridional overturning circulation (MOC). Climate threshold responses have

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.

Avoiding Dangerous Anthropogenic Interference with the Climate System

The UN Framework Convention on Climate Change calls for the avoidance of “dangerous anthropogenic interference with the climate system”. Among the many plausible choices, dangerous interference with

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

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

An overview of geoengineering by stratospheric sulphate aerosols is provided, summarizing the past 30 years of work, highlighting some very recent studies using climate models, and discussing methods used to deliver sulphur species to the stratosphere.


▪ Abstract Geoengineering is the intentional large-scale manipulation of the environment, particularly manipulation that is intended to reduce undesired anthropogenic climate change. The post-war

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

“Sunshade World”: A fully coupled GCM evaluation of the climatic impacts of geoengineering

Sunshade geoengineering ‐ the installation of reflective mirrors between the Earth and the Sun to reduce incoming solar radiation, has been proposed as a mitigative measure to counteract


This Article identifies four major global climate change problems, analyzes whether the most prominent of the greenhouse gas (GHG) control proposals is likely to be either effective or efficient in
