Changing Climate, Changing Migration: Connecting the Dots: How Climate Detectives Link Human-Caused Environmental Change to Migration

Migration Policy Institute Podcasts

It is no easy task to say with certainty that a particular storm, drought, or other extreme weather event causes human displacement, or that those individual events are due to human-caused climate change. Hurricanes, wildfires, mudslides, monsoons, and other sudden-onset events, as well as slow-onset ones such as drought, extreme heat, and sea-level rise have happened for millennia. To attribute specific impacts to human-made environmental change requires scientists to parse through years of data and pattern detection. In this episode, we speak with climate scientist Lisa Thalheimer, of the International Institute for Applied Systems Analysis, to explain how experts untangle the connections between climate change and migration.
