Former Sen. James Inhofe, an Oklahoma Republican who died on Tuesday, was infamous for his climate change denial. He once held up a snowball in the U.S. Senate chamber to argue that, because it was snowing in Washington in February, climate change was a “hoax.” The denial that he and others promoted for years persuaded some people to ignore both science and the changes in weather patterns happening around them.

As the world faces record-breaking heat waves and extreme storms, Macalester College anthropologist Ron Barrett poses an interesting question: Can humanity still address climate change without believing it’s true?

Barrett looks back in history to germ theory, at a time when microscopes were just coming into use, to show how people can still make the right choices, even if they don’t understand a threat they can’t see.
