Geoengineering Discourse Confronting Climate Change

The Move from Margins to Mainstream in Science, News Media, and Politics

This research examines the trajectory of the contested field of geoengineering through critical discourse analysis of relevant science policy reports, news media journalism, and congressional hearings. The analysis reveals the evolution of notions of normalcy, legitimacy, and imperative around the controversial field of geoengineering.

Geoengineering, the idea of addressing climate change through large-scale technological projects, stands out among contested technologies in the degree to which its scope of possibilities and its premise are characterized by global existential risks. Despite controversy, this field has been shifting toward mainstream consideration. Geoengineering Discourse Confronting Climate Change: The Move from Margins to Mainstream in Science, News Media, and Politics examines the trajectory of geoengineering through critical discourse analysis of three key genres: science policy reports, news journalism, and congressional hearings. Brynna Jacobson explores how reports from distinguished scientific societies have constructed certain notions of legitimacy around geoengineering, how narratives within news coverage have reflected and shaped the public discourse and understanding of geoengineering, and how geoengineering has garnered political support from both major political parties in the United States. Through analysis of discursive conventions within these genres, the author reveals the evolution of notions of normalcy, legitimacy, and imperative around the field of geoengineering.
