Last month, the Trump administration proposed revoking the landmark 2009 scientific finding, that’s been the basis for EPA regulation of greenhouse gas emissions under the Clean Air Act. If the proposal is finalized, it’s almost certain to be challenged in court.

And if the administration succeeds, experts warn that it could jeopardize the health of millions of Americans, especially children. Pediatrician Debra Hendrickson is a clinical professor at the University of Nevada Medical School and the author of “The Air They Breathe: A Pediatrician on the Front Lines of Climate Change.”

Dr. Hendrickson, what would be the effect of revoking this finding on the health of Americans, especially children?

Dr. Debra Hendrickson, University of Nevada School of Medicine: Well, if they revoke this finding, it knocks out a major pillar in our fight against the growing wildfires, rising heat waves and worsening floods and hurricanes we’ve been seeing for the past two decades. And it makes it more likely that all of these problems will continue to get worse in the future.
