The Hazy Ethics of Solar Radiation Management: Examining the Moral Turpitudes of Aerosol Geoengineering Any humane and responsible person must conclude that if the ends, however desirable, areuncertain and the means are horrible and certain, these means must not be employed.” -Howard Zinn Future historians will surely regard the passage between the twenty and twenty-firstcentury as the first period where human activity was recognized to distinctly alter the biogeochemical makeup of Earth’s atmosphere. The greater dilemma, however, is whether disruption of the Holocene climate will arise from unintentional, unabated greenhouse gasemissions alone, or will governments, perhaps unilaterally, inject aerosols (particles such assulfates or aluminum nanoparticles to act as cloud-formation precursors) into the troposphere andstratosphere in an attempt to lower the final amount of solar energy which reaches Earth. While solar radiation management (SRM) or stratospheric aerosol geoengineering (SAG) may have theostensible merit of counterbalancing the warming associated with the presence of increased greenhouse gases in the atmosphere, this would surely mark the end of the “natural world” or wilderness. While this might be considered semantics by some, even David Keith, perhaps themost eminent proponent of geoengineering in the public space, understands that, “humanity would henceforth need to acknowledge that they are living in a zoo, playing the role of both the animals and the zookeepers” <continues> -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
