The Connecticut Institute for Resilience & Climate Adaptation (CIRCA) is a multi-disciplinary research center bringing together experts in the fields of natural sciences, engineering, economics, political science, finance, and law to create practical solutions to climate change challenges. CIRCA collaborates with local, regional, and national partners to translate research into real-world action that protects lives, property, and natural environments.
Annually, the UN Conference of the Parties (COP) hosts its official Climate Change Conference in a different host city around the world, bringing together diplomats, business executives, environmental activists, NGOs, government and university leaders, and other delegates to discuss global progress towards climate change solutions. The UConn@COP Fellowship Program, which began in 2015 (COP21), sends a group of students and faculty to the conference each year; participants have spoken on panels, networked with global leaders and activists, attended film screenings, and connected with like-minded passionate students from other colleges and universities. The UConn@COP program supports the development of future leaders in climate science and policy, encouraging student engagement and cultural immersion in a unique experiential learning opportunity.
