Abstract
How do we understand national climate change politics in the United States Using a methodological innovation in network analysis this paper analyzes discussions about the issue within the US Congress Through this analysis the ideological relationships among speakers providing Congressional testimony on the issue of climate change are mapped For the first time issue stances of actors are systematically aggregated in order to measure coalitions and consensus among political actors in American climate politics in a relational way Our findings show how consensus formed around the economic implications of regulating greenhouse gases and the policy instrument that should do the regulating The paper is separated into three sections First we review the ways scholars have looked at climate change policymaking in the United States paying particular attention to those who have looked at the issue within the US Congress Next we present analysis of statements made during Congressional hearings on climate change over a fouryear period Our analysis demonstrates how a polarized ideological actor space in the 109th Congress transforms into a more consensual actor landscape in the 110th Congress which is significantly less guided by partisan differences This paper concludes by discussing how these findings help us understand shifting positions within American climate politics and the implications of these findingsThis research was supported by the US National Science Foundation BCS0826892 The authors would like to thank the many students who helped code these data Earlier versions of this paper were presented at the 2010 meeting of the American Geophysical Union the 2011 meeting of the American Association for the Advancement of Science the US National Oceanic and Atmospheric Administration and the Brookings Institution
