Science studies, climate change and the prospects for constructivist critique

Abstract

Starting from the debates over the ‘reality’ of global warming and the politics of science studies, I seek to clarify what is at stake politically in constructivist understandings of science and nature. These two separate but related debates point to the centrality of modern science in political discussions of the environment and to the difficulties, simultaneously technical and political, in warranting political action in the face of inevitably partial and uncertain scientific knowledge. The case of climate change then provides an experimental test case with which to explore the various responses to these challenges offered by Ulrich Beck's reflexive modernization, the normative theory of expertise advanced by Harry Collins and Robert Evans, and Bruno Latour's utopian vision for decision-making by the ‘collective’ in which traditional epistemic and institutional distinctions between science and politics are entirely superseded.
