Due to the self-reinforcing nature of the process, these expectations tend to perpetuate themselves for long periods of time, even though they may have arisen(More)
If the term geoengineering is restricted to deliberate manipulation of the entire global climate, the most evident possibility derives from a remarkable feature of nature. For whatever deep or arbitrary reason, sulfate molecules injected into the stratosphere can offset the radiative forcing effect of the principal greenhouse gas, carbon dioxide, with(More)
