As the United States struggles with national solutions to climate change, state and local governments have increasingly taken policy action in this area. Although existing research addresses why some places adopt climate change policy while others do not, much of this expresses policies as a function of factors in the present period or recent past, leaving the question of whether current climate change policy can be seen as a lagged response to longer term trends largely unaddressed. Examination of climate change policy as a response to longer term changes expands the existing understanding of why locations choose to be active in this area. Pairing unique climate change policy survey data from more than 200 local Great Plains governments with Census and environmental data from 1990 to 2000, this article examines whether changes in local socioeconomic and environmental factors in the 1990s are associated with climate change mitigation and adaptation policy adoption from the following decade, 2000–2010.
