As the possibility of any real settlement coming from the climate negotiations in Cancun ebbs away, perhaps it is time to take another look at geoengineering. Geoengineering is a kind of science fiction. It is the systematic attempt to either reduce the amount of energy coming into the earth-atmosphere system or scrub the atmosphere of excess CO2. While some of the ideas associated with Geoengineering are outlandish and seem more science fiction than realistic possibilities, the idea of intentionally scrubbing the atmosphere of excess CO2 is behind some of the existing proposals being debated.
