Nationally, 72% of Americans believe global warming is happening. But when public opinion researchers zoom in on Americans, they find that attitudes and opinions about climate change can vary drastically from county to county—even when those counties are next door. Public opinion factors into how policy-makers respond to climate change, including taking steps to reduce CO2 levels and mitigate harmful impacts already being experienced. 

Stacker compiled a list of counties most concerned about climate change in Ohio using data from the Yale Program on Climate Change Communication. Counties are ranked by the percent of residents that are worried about global warming.
