''Geoengineering'' has been proposed as a [[potential]] third [[option]] for tackling global warming, alongside mitigation and adaptation. Scientists do not typically suggest geoengineering as an alternative to [http://en.wikipedia.org/wiki/Air_pollution emissions control], but rather an accompanying strategy. Reviews of geoengineering techniques have emphasised that they are not substitutes for emission controls and have identified potentially stronger and weaker schemes. | ''Geoengineering'' has been proposed as a [[potential]] third [[option]] for tackling global warming, alongside mitigation and adaptation.
