Taking geoengineering seriously

Scientific American has an extensive feature on geoengineering in its November issue including references for further study. It looks at such possible technologies as injecting sulphur dioxide into the upper stratosphere, spraying seawater in the troposphere and building huge “blinds” in space to act as a sunshade. At least the magazine takes the discussion seriously although a related editorial ends by coming out against the technology on several grounds: the danger of side effects, cost and the false sense of security it would engender.

To me there is much room for further investigation and debate.
