Could a Super El Niño Displace Millions from Their Homes?
A forecasted historic El Niño, labeled “Super Godzilla,” is expected to peak in late 2026 and turn 2027 into the hottest year ever recorded on the planet. Expected to be the largest El Niño in at least 1,000 years, the event is expected to result in extreme temperatures, devastating rainfall and droughts, and other unusual weather patterns globally. Although the event is a naturally occurring phenomenon in the Pacific, its impacts are magnified by human-caused climate change. That could lead to huge displacement. In this episode, we speak with Alexander Kjærum, a global advisor and senior analyst with the Danish Refugee Council (DRC) who has forecasted some of the potential displacement impacts of the super El Niño. He explains why the weather system may lead to new displacement, highlights specific examples around the world, and discusses how organizations are seeking to use anticipatory action to protect people before disaster strikes.

Precedent or Cautionary Tale? The U.S. Climate-Driven Relocation of Isle de Jean Charles
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
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. Chapters 01:41 Climate Impacts Unfolding in Fiji 04:54 Government-Led Planned Relocation Framework 08:17 The Concept of Vanua: Cultural Ties to Land 13:10 Community Concerns and Decision-Making Around Relocation 16:44 Fiji as a Regional Migration Destination 22:16 Policy Gaps and Research Priorities

How the World Is Learning to Respond Collectively to Climate Displacement
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?
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
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. Subscribe to Changing Climate, Changing Migration on Apple, Spotify or YouTube.

First Displacement, then Disasters: How Refugees Contend with Climate Change
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. Want to dive deeper?
