Climate Security: A Pre-Mortem Approach to a Sustainable Global Future

Climate Security has been described as the defining threat of the 21st Century. John Comiskey and Michael Larrañaga take a “pre-mortem” look at this emerging challenge. In this Short Talk, they provide an unique framework for thinking through the global consequences we may face if the United States and other countries fail to recognize how climate change threatens our security and way of life. (Recorded on February 18, 2020, at the Annual CHDS Alumni APEX Workshop, Monterey, CA.)
