ABSTRACT
Geoengineering – the intentional alteration of the Earth and its atmosphere on a planetary scale – first appeared on the climate change agenda in 1965. 2 Since then, however, no efforts to develop geoengineering have moved past the early experimental phase. Scientists – even those who support geoengineering research – have been reluctant to consider the technology because it could distract from reducing emissions and lull the public into a false sense of security about a technology that is untested and has significant drawbacks.
