Yale Climate Opinion Maps 2018: These maps show how Americans’ climate change beliefs, risk perceptions, and policy support vary at the state, congressional district, metro area, and county levels, based on data through the year 2018. 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. Public opinion polling is generally done at the national level, because local level polling is very costly and time intensive. The YCOM team of scientists has developed a geographic and statistical model to downscale national public opinion results to the state, congressional district, and county levels. This enables better estimates of public opinion across the country and reveal a rich picture of the diversity of Americans’ beliefs, attitudes, and policy support by region. National surveys show that 70% of Americans think global warming is happening. The new YCOM model estimates, however, also show that while only 50% of people in Emery County, Utah agree, 73% in neighboring Grand County, Utah believe global warming is happening.
