This episode explores what really drives people to move in a rapidly warming world, and why we still have no legal protection for those displaced by climate disruption. Herb Simmens is joined by climate system scientist Paul Beckwith and physician Dr. Peter Carter to unpack the tangled links between heat, drought, food insecurity, conflict, and the politics of borders. They highlight how most climate-related displacement is internal and temporary so far, yet already reshaping societies and fueling nationalist backlashes.
