Yale Climate Opinion Maps for Strategists


This version of the Yale Climate Opinion Maps is based on data through spring 2019. Public opinion about global warming is an important influence on decision making about policies to reduce global warming or prepare for the impacts, but American opinions vary widely depending on where people live. So why would we rely on just one national number to understand public responses to climate change at the state and local levels? Public opinion polling is generally done at the national level, because local level polling is very costly and time intensive. Our team of scientists, however, has developed a geographic and statistical model to downscale national public opinion results to the state, congressional district, and county levels. We can now estimate public opinion across the country and a rich picture of the diversity of Americans’ beliefs, attitudes, and policy support is revealed.

Our national surveys show that 67% of Americans think global warming is happening. Our new YCOM model estimates, however, show that only 45% of people in Emery County, Utah agree. Meanwhile 69% in neighboring Grand County, Utah believe global warming is happening.

Explore the maps by clicking on your state, congressional district, or county and compare the results across questions and with other geographic areas. Beneath each map are bar charts displaying the results for every question at whichever geographic scale is currently selected.

See the methods page for more information about uncertainty estimates. In some cases, numbers that should sum to 100% or differences from the national average that should sum to zero are off by one percentage point; these effects are due to rounding errors.
