Precedent or Cautionary Tale? The U.S. Climate-Driven Relocation of Isle de Jean Charles

Season 1 · Episode 55

Friday, August 28, 2026 • Duration 33:46

In 2016, the U.S. federal government provided $48 million to relocate the climate-threatened Louisiana island of Isle de Jean Charles. The effort, which was the government’s first climate-driven community relocation project, was closely watched as a potential model for the future.

But the relocation was more challenging than originally anticipated. Many residents who were members of a Native American tribe felt they had been treated unfairly or were excluded from decisionmaking. In the end, some tribal leaders referred to the process as a “cultural genocide.”

We speak with Jessica Simms, a cultural geographer who was Louisiana’s lead outreach and engagement coordinator for the resettlement effort. She traces the array of factors behind the decision to relocate and the mix of successes and challenges along the way.

Fiji on the Front Lines of Climate Mobility

Season 1 · Episode 54

Friday, July 31, 2026 • Duration 31:34

Fiji has long been at the forefront of developing policies to help its residents voluntarily relocate to escape the extreme effects of climate change. The country, which is comprised of hundreds of islands in the Pacific, faces rising sea levels, extreme weather, and other dangers.

But for many Fijians, the choice to pack up and leave home is a difficult one. Many have a deep spiritual and personal connection to place, a concept known as vanua. Meanwhile, as one of the largest economies in the region, Fiji is also a destination for migrants from other Pacific Island countries, including those threatened by climate change.

How has the government tried to support people who move? What considerations do residents consider when deciding whether to relocate? And what is the response to immigration from other countries?

On this episode, we discuss these issues with Sargam Goundar, a Fijian doctoral researcher at the University of Otago.

How the World Is Learning to Respond Collectively to Climate Displacement

Season 1 · Episode 53

Tuesday, June 30, 2026 • Duration 28:46

The coordinated global response to climate change-driven displacement is relatively new. Just a few decades ago, virtually no governments were paying attention to the ways in which people were being displaced by extreme weather, sea-level rise, and other climate events. Although the international response remains a work in progress, significant strides have been made to bring the world together.

One of the people responsible for that coordination is Walter Kälin, a longtime humanitarian expert and legal scholar who is now the Envoy of the Chair of the Platform on Disaster Displacement, a country-led initiative that works to protect people at risk of climate-related displacement. In this discussion, he breaks down where things stand today in terms of a coordinated response and how things might evolve in the future.

Climate Change Is Making People Sick. Can Migration Help?

Season 1 · Episode 52

Tuesday, May 26, 2026 • Duration 34:11

Climate change can be devastating for individuals’ health and safety. Climate-linked natural disasters can cause physical injuries and damage health-care systems, while slow-onset changes such sea-level rise can lead to the spread of disease and make it harder for people to obtain care.

In that context, leaving a climate-vulnerable place can potentially lead to better health outcomes—but only under the right circumstances.

In this episode, we speak with Ilse Ruyssen, an economist at Ghent University and the UN University Institute on Comparative Regional Integration Studies, who leads the CliMigHealth research network.

Priced Out: Climate Change, Home Insurance, and the People Stuck in the Middle

Season 1 · Episode 51

Thursday, April 23, 2026 • Duration 31:07

Climate change is making home insurance more expensive and less available, as the multibillion-dollar losses caused by hurricanes, wildfires, and other disasters increase in scale. Rising insurance premiums can push some people to relocate or force others to either pay more money to remain in their home or go without insurance and risk catastrophe if disaster strikes. Residents, insurance companies, and policymakers in high-income countries are beginning to reckon with these issues and are working to find a way to adequately offset risk without charging exorbitant prices. This episode features Talley Burley, who analyzes climate risk and insurance at the Environmental Defense Fund.

First Displacement, then Disasters: How Refugees Contend with Climate Change

Season 1 · Episode 50

Thursday, April 9, 2026 • Duration 30:16

Refugees are often some of the people most vulnerable to climate change. After fleeing armed conflict or persecution, many refugees end up in camps located in rural areas, with few resources and little support. That can leave them vulnerable to floods, storms, extreme heat, or other impacts of climate change.

This episode focuses on these impacts, with insights from Ayoo Irene Hellen, a South Sudanese refugee in Uganda and climate advocate. She discusses her own experiences, those of her community, and the value of including refugee voices in planning.

Climate Displacement from Indigenous Lands

Season 1 · Episode 49

Monday, February 23, 2026 • Duration 24:20

Many Indigenous people have a deep connection to their ancestral homelands that dates back centuries. What happens when climate change and other factors force them to move away from those lands? This episode discusses issues affecting Indigenous people, especially in the Americas. Our guest is environmental scientist Jessica Hernandez, a climate justice and Indigenous advocate. She discusses the factors compelling migration for Indigenous communities, their experiences after migration and the dearth of Indigenous voices in policy discussions over climate change and migration.

Is Climate-Vulnerable Africa Prepared for Increased Displacement?

Season 1 · Episode 48

Monday, January 26, 2026 • Duration 39:15

Africa may be the most climate-vulnerable region of the world, with drought, extreme heat and storms, and other impacts affecting millions across the continent. These environmental events have forced people from their homes and in some cases even contributed to conflict between different groups. By far, most climate-affected individuals who migrate stay either within their own country or go elsewhere on the continent, rather than migrating beyond Africa.

How prepared is the continent for a future of increased displacement? Governments are making some strides to accommodate displaced people—although there is often a gap between official rhetoric and the realities on the ground. This episode discusses climate-linked migration issues across Africa with Aimée-Noël Mbiyozo, a senior research consultant at the South Africa-based Institute for Security Studies.

Trapped by Climate Change: The Economics of Staying or Leaving

Season 1 · Episode 47

Tuesday, December 16, 2025 • Duration 30:03

It is not guaranteed that someone harmed by a natural disaster or other environmental change will leave their home. A complicated web of factors affects whether climate-vulnerable individuals want to—or even can—move. One of these factors is financial: How much money or other resources someone has at their disposal.

In this episode, we speak with Kelsea Best of The Ohio State University about climate (im)mobility and the economic and other factors that help shape futures amid changing climates. We also discuss the notion of “climate gentrification,” which occurs when wealthier people move into traditionally lower-income neighborhoods that are better shielded from natural disasters and other environmental harms.

The Young Lives Uprooted by Climate Change

Season 1 · Episode 46

Monday, November 10, 2025 • Duration 27:01

Children are especially vulnerable to displacement linked to climate change. Each year, millions of young people are displaced by weather-related disasters, as schools and other services break down and adults send children away to find safety. Forced from their homes, children often face new challenges, including being unable to access education or medical care, and even heightened risk of violence and other dangers. Despite the unique challenges that children face in displacement, there are relatively few international laws or systems particularly designed to assist those forced to move because of environmental factors. We speak with UNICEF’s Laura Healy about this reality and the opportunities to better protect children in a warming world.
