This episode is dedicated to our latest issue of Peace Policy, which focuses on the co-mingling of two existential crises of our time: the threat of nuclear war, and potential planetary destruction through climate change.   Atalia Omer, Professor of Religion, Conflict and Peace Studies, serves as this year’s faculty editor of Peace Policy. She is joined by George A. Lopez, Rev. Theodore M. Hesburgh, C.S.C., Professor Emeritus of Peace Studies and the guest editor of this Peace Policy issue, for a conversation about essays from our expert contributors, ranging from environmental and nuclear risks in Ukraine, to Pope Francis, to climate change.   Contributors to this issue of Peace Policy include Rachel Bronson, president and CEO of The Bulletin of the Atomic Scientists; Drew Marcantonio (Ph.D. '21), Department of Management & Organization within the Mendoza College of Business at the University of Notre Dame, as well as a faculty fellow with the Kroc Institute, and Kristina Hook (Ph.D. '20), an assistant professor of Conflict Management with Kennesaw State University in Georgia; and Jerry Powers, director of Catholic Peacebuilding Studies at the Kroc Institute and coordinator of the Catholic Peacebuilding Network.
