Considering SRM to control anthropogenic greenhouse gas emissions

Solar radiation management (SRM) has been proposed as a form of geoengineering to reduce the climate effects of anthropogenic greenhouse gas emissions.

Modelling studies have concluded that SRM, through a reduction in total solar irradiance by approximately 2%, roughly compensates for global mean temperature changes from a doubling of carbon dioxide concentrations.

This paper examines the impact of SRM on the terrestrial hydrologic cycle using the Community Land Model, version 4, coupled to the Community Atmosphere Model, version 4, with reductions in solar radiation relative to simulations with present-day and elevated CO2 concentrations. There are significant global and regional impacts due to vegetation–climate interactions that are not compensated when reductions in total solar irradiance of 1%, 2%, and 3% are imposed on top of a doubling of present-day CO2 concentrations.

(Any form of intentional geoengineering of our planet is indicative of systemic failure by humanity. Surely we are intelligent enough to see the damage we are doing, understand the cause, recognize why it is happening, and subsequently change our behaviour without resorting to a technology or process that could have an even more damaging unintended consequence – Robert McLean.)
