The small island nations that make up the Caribbean are incredibly vulnerable to the impacts of climate change. Many people and businesses are concentrated along the coastline, exposing them to intensifying hurricanes and rising sea levels. Are these hazards prompting greater displacement, either within the region or beyond? And could they reduce tourism, prompting economic shocks to countries dependent on vacationers? This episode discusses these issues and others with Natalie Dietrich Jones, a migration expert at the University of the West Indies.

Does AI have a role to play in mapping and predicting climate migration trends? In this episode of the podcast, we explore the issue with John Aoga, a postdoctoral researcher at UCLouvain in Belgium. He led a study using machine learning algorithms to trace how climate shocks affected migration intentions in several countries in West Africa. We discuss his findings and the broader promise and peril of using these types of technologies to map and predict migration flows.

Under the right circumstances, climate-induced migration can aggravate the drivers of violent conflict. In places such as the Middle East and West Africa’s Sahel region, migration during times of environmental precarity can upset delicate social and demographic balances and place additional pressure on local authorities. Left to fester, the results can be deadly. This episode explores this connection between climate change and human mobility in conversation with journalist Peter Schwartzstein, author of the book The Heat and the Fury: On the Frontlines of Climate Violence.
