Precaution and Solar Radiation Management

Ethics, Policy & Environment, 2012
Solar 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

2012
SRM 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

2012
There 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 ...

The Effects of Solar Radiation Management on the Carbon Cycle

Current Climate Change Reports, 2018
Review 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

2014
Proposals 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, 2017
Geoengineering 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, 2018
ABSTRACTTechnologies 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

Fail-safe solar radiation management geoengineering

Mitigation and Adaptation Strategies for Global Change, 2012
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 maintaining the rate of change in temperature to within 0.2 °C per decade. This paper supposes that a geoengineering option of solar radiation management (SRM) by

Will Geoengineering With Solar Radiation Management Ever Be Used?

Ethics, Policy & Environment, 2012
As a meteorologist, I understand the limits of prediction of physical systems, let alone human ones, but here I will attempt to predict whether geoengineering will ever be used.

Solar Radiation Management, Cloud Albedo Enhancement

2012
Cloud 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.
