Healing the Hole: The Ozone's Road to Recovery

This Earth Day, we’re celebrating a triumph of human endeavor: the healing of the ozone layer! Many listeners will remember the hole that formed in the ozone layer, due in large part to human-made chemicals like chlorofluorocarbons, or CFCs. My guest this week is Dr. Paul Newman, a Senior Scientist at the University of Maryland Baltimore and retired NASA Chief of Atmospheric Sciences. We’ll dive into what these chemicals are, how they damaged our vital ozone layer, and how countries around the planet came together to repair the damage we caused.
