Our world is built on the assumption of climate stability. Today, this assumption no longer holds. The Climate Mobility pillar of Carnegie’s Sustainability, Climate, and Geopolitics Program studies how people are responding to climate change-related shifts in the habitability of their geography. Deploying climate mobility as an adaptation strategy will require a new level of public understanding, good policy design and implementation, more data and analytic tools, better financing, and more effective institutions at the subnational, national, and multilateral level. Our program provides thought leadership and innovative thinking to support people on the move in the context of climate change, as well as to limit climate as a driver of displacement. Our research covers policies to enable climate mobility, including effective disaster aid systems, adaptation finance, policy-relevant data and tools, and the governance of cross-border climate mobility.
