The Yale researchers created a map of all U.S. states, with different colors and shades reflecting global warming attitudes.

University of Wyoming energy economics professor Rob Godby noted that the Yale map could be superimposed with any electoral map from the 2016 presidential race.

The states with the highest proportion of responses that humans are not causing climate change are the ones in which President Donald Trump won by the largest margins, Godby said.

And in Wyoming, seven in 10 voters voted for Trump, the highest proportion in the country.

In most industrialized countries, climate change is accepted as science, since over 90 percent of researchers agree that humans are contributing to the warming of the planet, Godby said. But in the U.S., the issue has become politicized, he said.

“What that means is if you’re on one side, you choose to believe in one thing and if you’re in another side, you believe in another thing,” he said.

Godby blames the media in part. He said that each time there’s a story about climate change, there’s always one source who is arguing about its existence and another against – creating an illusion that the scientific community is split on the issue when it is not, he said.
