Abstract

How, and when, does it become possible to conceptualize a truly planetary crisis? The Cold War nuclear arms race installed one powerful concept of planetary crisis in American culture. The science enabling the US nuclear arsenal, however, also produced unintended byproducts: notably, a radical new investment in the earth sciences. Cold War nuclear science ultimately produced not only bombs, but also a new understanding of the earth as biosphere. Thus, the image of planetary crisis in the US was increasingly doubled during the Cold War — the immediacy of nuclear threat matched by concerns about rapid environmental change and the cumulative effects of industrial civilization on a fragile biosphere. This paper examines the evolution of (and competition between) two ideas of planetary crisis since 1945: nuclear war and climate change. In doing so, the paper offers an alternative history of the nuclear age and considers the US national security implications of a shift in the definition of planetary crisis from warring states to a warming biosphere.
