Should high‐income countries engage in solar geoengineering research and possible deployment? On the assumption that the speed of the energy transition will be insufficient to abate catastrophic climate impacts, research into solar geoengineering begins to look like a technically and socially feasible route to mitigate such impacts. But on the assumption that a rapid and relatively just energy transition is still within the realm of political possibility, research into solar geoengineering looks more like an ideological tool designed to divert time (...) and resources from less risky climate solutions. At the heart of debates over solar geoengineering, then, is disagreement over what political actors can be expected to do in the future. In this article, I argue that both objectors to and proponents of solar geoengineering research often make background assumptions regarding expected future actions that are either (a) inaccurate or (b) inconsistent. I propose an account of expected future actions that avoids these problems and sketch what the debate over solar geoengineering looks like with these assumptions in place. (shrink)

As capitalist society remains incapable of addressing climate breakdown, one measure is waiting in the wings: solar geoengineering. No other technology can cut global temperatures immediately. It would alleviate the symptoms of the crisis, not its causes. But might it be combined with radical emissions cuts? This essay, the first instalment of two, scrutinises the rationalist-optimist case for geoengineering: the idea that soot planes in the sky can shield the Earth from the worst heat while society rids itself of fossil (...) fuels. A more likely outcome is that they encourage business-as-usual to continue, while negative side-effects from geoengineering itself pile up. The logic of the enterprise points in the direction of a catastrophic termination shock. A subsequent, second instalment will subject geoengineering to a materialist psychoanalysis and argue that it represents a fantasy of repression, setting itself up for a dreadful return of the repressed.
