Lecture title: The Antarctic Ozone Hole: A Global Success Story of Science and Policy

Lecture date: Wednesday, April 14, 2021
Online webcast with Q&A

Lecture description: The 1985 discovery of a massive hole in the Antarctic ozone layer shocked the world and led to remarkable changes in environmental science, public understanding, and policy. In this talk, atmospheric chemist Professor Susan Solomon—recognized by the Killian Award Selection Committee for her scientific contributions and her leadership in the policy aspects of climate change—will briefly summarize how scientific discoveries led to a new understanding of the chemistry that controls the ozone layer, our planet’s essential “sunscreen” against damaging ultraviolet light from the sun. She will also describe how the nations of the world came together in an international process that has now effectively phased out the production of ozone-depleting chemicals. Lastly, Professor Solomon will discuss some of the evidence that the ozone layer is slowly beginning to heal.
