''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.

There are no known large-scale geoengineering projects except one conducted outside the scientific [[mainstream]] by [http://en.wikipedia.org/wiki/Russ_George Russ George]. Almost all [[research]] has consisted of [[computer modelling]] or [[laboratory]] tests, and attempts to move to real-world [[experimentation]] have proved [[controversial]]. Some limited tree planting and cool roof projects are already underway. Ocean [http://en.wikipedia.org/wiki/Iron_fertilization iron fertilization] has been given small-scale research trials. Field research into [http://en.wikipedia.org/wiki/Stratospheric_sulphur_aerosols_(geoengineering) sulfur aerosols] has also started.
