Regulating Solar Radiation Management
European Journal of Risk Regulation, 2016Climate engineering in general and solar radiation management (SRM) in particular raise profound and complex political, legal, social, and ethical questions that go well beyond technical feasibility issues. We consider three such questions. First, can existing EU decision-making processes accommodate sufficient public engagement to ensure legitimate ...

Precaution and Solar Radiation Management
Ethics, Policy & Environment, 2012Solar radiation management is a form of geoengineering that involves the intentional manipulation of solar radiation with the aim of reducing global average temperature. This paper explores what precaution implies about the status of solar radiation management.

Stratospheric Aerosols for Solar Radiation Management
2012SRM in the context of this entry involves placing a large amount of aerosols in the stratosphere to reduce the amount of solar radiation reaching the surface, thereby cooling the surface and counteracting some of the warming from anthropogenic greenhouse gases.

Sunshades for Solar Radiation Management
2012There is strong scientific consensus that the Earth’s climate has been warming over the last century and that this warming is primarily due to human influences on the climate system (IPCC 2007). Attempts to curb human emissions of greenhouse gases have so far largely failed; as such, and in an attempt to avoid or delay potential dangerous climate ...

Regional climate response to solar-radiation management
Nature Geoscience, 2010Modelling studies suggest that management of solar radiation could produce stabilized global temperatures and reduced global precipitation. An analysis of a large-ensemble simulation of 54 temperature-stabilization scenarios suggests that it may not be possible to achieve climate stabilization through management of solar radiation simultaneously in all

The Effects of Solar Radiation Management on the Carbon Cycle
Current Climate Change Reports, 2018Review existing studies on the carbon cycle impact of different solar geoengineering schemes. The effect of solar geoengineering on terrestrial primary productivity is typically much smaller than that of CO2 fertilization. Changes in the partitioning between direct and diffuse radiation in response to stratospheric aerosol injection could substantially

Solar Radiation Management and the Governance of Hubris
2014Proposals for the intentional engineering of the Earth's climate through techniques of solar radiation management (SRM) have been accompanied by profound questions of governance. As the purpose, goals and motivations of SRM are considerations of paramount importance, governance must not only encompass risks and unintended consequences, but also intent.

Solar radiation management and ecosystem functional responses
Climatic Change, 2017Geoengineering such as solar radiation management (SRM) can be an emergent option to avoid devastating climatic warming, but its ramifications are barely understood. The perturbation of the Earth’s energy balance, atmospheric dynamics, and hydrological cycling may exert unexpected influences on natural and human systems.

Governing the termination problem in solar radiation management
Environmental Politics, 2018ABSTRACTTechnologies for Solar Radiation Management (SRM) could limit global warming by manipulating the Earth’s radiation balance. A major objection to SRM is the termination problem: the catastrophic consequences that are likely to result from its sudden discontinuation. The termination problem limits the reversibility of policy choices and poses the

Solar Radiation Management, Cloud Albedo Enhancement
2012Cloud albedo enhancement is one of several possible methods of solar radiation management by which the rate of increase in world temperatures could be reduced or even reversed. It depends on a well-known phenomenon in atmospheric physics known as the Twomey effect.
