Among the earliest examples of the disruptions that climate change can bring, some low-lying island countries in the Pacific Ocean are facing serious threats from rising sea levels and coastal erosion. Over the long term, atoll nations such as Kiribati, Tuvalu, and the Marshall Islands might eventually need to relocate some or all of their populations. But not everyone wants to migrate, and governments have balanced supporting people who relocate with other ways of adapting to changing conditions.

Climate change is already affecting how, whether, and where people migrate. But environmental change is likely to become more extreme, unless the world takes serious action now. How might changes made now impact what future migration looks like? This Changing Climate, Changing Migration episode features a conversation with Robert McLeman, a geographer and environmental studies expert at Canada’s Wilfrid Laurier University, about the possible scenarios that lie ahead for the relationship between climate change and migration, depending on how countries act in the next few decades.
