Geoengineering is a diverse set of environmental technologies proposed to intervene strategically in Earth processes in order to combat climate change. Take for example, a plan to reduce solar radiation via aerosol clouds emitted from airplanes, or one that attempts to remediate ocean acidification by means of algae blooms created by dumping iron from ships. But like the anthropocene, geoengineering is an ambiguous term. Social scientists seem to criticize both the anthropocene and geoengineering as much as they praise them. However many “Good Anthropocenes” emerge in climate discourses, there are just as many millennarist visions . Just as geoengineering is argued to be an expression of capitalist eco-colonialism , others welcome its opening towards new relations with/in earth-systems . But since geoengineering eludes the confines of a single attitude, historical precedent, or political motive, it may not be analytically prudent to treat as a totality. Thus anthropological inquiry, never content with reductionist critique or blind advocacy, could be especially adept at understanding this thing called geoengineering. This might be possible, in an admittedly indulgent yet I believe necessary fashion, by defining and differentiating its characteristics using a particular rubric: a Foucault-indebted biopolitics. Biopolitical analysis, always concerned with the specificities of a given apparatus, could allow an anthropologist to drive a stake between two geoengineering proposals’ different political histories perhaps, or conversely, to uncover common economic practices hidden in otherwise unrelated proposals, for example.
