2025 marks the 54th anniversary of Sarasota Institute of Lifetime Learning’s (SILL) “Global Issues” series. This hard-hitting series, which runs January 7-March 27, features internationally renowned experts discussing a wide range of domestic and global issues. This month’s lectures feature front-page issues examined by leading speakers, including Bob Bunting, a scientist and CEO of the Climate Adaptation and Mitigation Center, who will describe how our health will be impacted by climate change;  Dr. Wendy Whitman Cobb, professor of strategy and security studies at the School of Advanced Air and Space Studies, who will discuss the ways in which space is increasingly congested, competitive, and contested; and Dr. Charles Kupchan, a senior fellow at the Council on Foreign Relations (CFR) and professor of international affairs at Georgetown University, who warns that the West faces an acute internal threat from political polarization and ideological extremism.
