A new economic group is tallying the costs of climate change in Oregon. Keaton Miller, an associate professor at the University of Oregon College of Arts and Sciences, is a part of the group and spoke with KATU, based in Portland. "It's some of these other things that are less visible but still impactful. And I think a really great example of that is the cost of smoke. You know, some of it is direct. Some of it is buying, you know, air purifiers, which a lot of my friends have done. A lot of classrooms at the university that I work at now have, you know, air purifiers in them," Miller said.
