4 This quantitative display of policy documents is limited to the years 1994–2020 as most of the relevant document collections within FDsys are only digitally available from 1994 onward. This applies, for example, to congressional hearings, the Federal Register, congressional bills, the Congressional Record, or congressional documents (see US Government Publishing Office (2018) for a detailed account of the availability of all FDsys collections). To explore the origins of climate engineering in US politics before that, we will turn to historical scholarship and scientific assessment reports (see Chapters 3 and 4).

63 Scholarship on the history of environmental reflexivity and the Anthropocene has convincingly argued that popular narratives of the redemptive power of science in the climate crisis run the risk of leaving unattended human agency in making this crisis, in making sense of this crisis, and in addressing this crisis (see, e.g., Bonneuil and Fressoz (2016); Hulme (2014); Locher and Fressoz (2012).
