New maps of climate opinions by political party

Estimated % of registered Republicans who think that global warming is happening

Estimated percent of Republicans who think that global warming is happeningOnline  —  There is a new online article: “The spatial distribution of U.S. Republican and Democratic climate opinions at state and local scales” in the journal Climatic Change Letters, plus the launch of a new interactive set of maps.

The paper and maps describe the distribution of both Democratic and Republican opinions in the USA on climate change across all US states and congressional districts.

The maps illustrate, for example, that 69% of Democrats in Alabama believe climate change is happening, but that is the lowest percentage of any states; in Oregon and California 88% of Democrats believe it is happening, and in Texas, it’s 82%.

Republicans are less convinced overall, but there is substantial spatial variability in their beliefs as well – for example, 62% of New York Republicans believe global warming is happening, while only 48% of Republicans in Nebraska and Kansas agree.

At the congressional district level, Republican views of climate change are even more heterogeneous, as the map above illustrates.

The new results build on their prior work (e.g., Howe et al. 2013, and Mildenberger et al., 2015) that estimated climate change opinions at state and local scales among the general population. This project, however, for the first time, maps spatial variations in opinion within the populations of Democrats and Republicans respectively.

The article and the maps should provide new insights into the political dynamics of climate change opinion and suggest new opportunities for bipartisan conversations about how to best address this critical challenge.
