Changing Climate, Changing Migration: What Exactly Is Climate Migration?

Migration is complex, and rarely is there only one single factor that prompts people to leave their homes. That is especially true when climate change is involved, since its impacts on internal and international migration are often indirect and hard to trace. So when we talk about climate migration, what exactly do we mean? And why is the distinction important? Kerilyn Schewel, co-director of Duke University’s Program on Climate-Related Migration, joins this episode of the podcast to help make sense of the terminology and why it matters.

Changing Climate, Changing Migration: Are Orderly Borders Possible in an Era of Rising Climate Migration?

When large numbers of asylum seekers and other migrants arrive at the borders of Western countries without prior authorization to enter, they are often treated as “spontaneous” arrivals. But migration is almost never truly spontaneous. Usually, human mobility across international borders is the result of complicated decision-making and a careful weighing of the costs and benefits. This episode features David Leblang, a professor of politics and public policy at the University of Virginia, who discusses how climate change fits into the migration calculus.

Changing Climate, Changing Migration: A Century of Climate Migration Upheaval? An Audacious Prediction for the Future

Is the world facing a chaotic century of mass migration spurred by climate change? As the planet’s temperature warms, award-winning environmental journalist Gaia Vince thinks so. In her book, Nomad Century: How Climate Migration Will Reshape Our World, she contemplates a future in which hundreds of millions of people move from one part of the globe to another in a planned and deliberate migration. We discuss her bold solutions for managing what she terms a species emergency in this episode.

Changing Climate, Changing Migration: Are Climate Migrants Treated Differently than Other Migrants?

Do host communities respond differently to people migrating because of environmental impacts compared to refugees fleeing war or migrants seeking work? Research suggests the answer is yes. Multiple factors affect relations between communities and new arrivals, and migrants’ perceived levels of deservingness can be influenced by the reasons why they move. In this episode, we speak with Sabrina Arias and Christopher Blair about their study of responses to climate migrants in the United States and Germany.

Changing Climate, Changing Migration: A Note of Caution about Exaggerating the Climate-Migration Link

Concerns that large amounts of people will be displaced by climate change and head to wealthy countries in North America and Europe are often misplaced, according to migration scholar Hein de Haas. These types of narratives can tap into anti-immigrant sentiments, allow governments to avoid responsibility for their own failures, and may overlook the large numbers of people forced to remain in place amid environmental disaster, he argues in this episode. 

Changing Climate, Changing Migration: When Climate Change Comes to Refugee Settings

Environmental disasters can force people out of their homes and communities, complicating responses to ongoing humanitarian protection efforts. As a result, many humanitarian organizations have started paying attention to the impacts of climate change for multiple aspects of their refugee protection work. For this episode, we speak with Joan Rosenhauer, the executive director of Jesuit Refugee Service/USA, about how natural disasters and other environmental harms affect her organization’s work and its faith-based mission.

Changing Climate, Changing Migration: Climate Change and Environmental Migration: View from the IOM

The UN migration agency, the International Organization for Migration (IOM), in 2015 created a special division responsible for migration-related issues involving the environment and climate change. The division just got a new leader and is looking to embark on a new agenda. This episode of the podcast features a discussion with new division head Manuel Marques Pereira, who talks about his office’s role and priorities in dealing with migration shaped by climatic events. 

Changing Climate, Changing Migration: Impacts of Extreme Heat: Global Warming and Migration

Global warming and extreme heat are behind many of the phenomena linked to climate change. Hotter weather also has an impact on migration and on migrants, particularly in destinations such as the Middle East and parts of the United States. In recent years, there has been more attention paid to cases of migrant workers dying from the heat. In this episode, we speak with Tord Kjellstrom, a physician and researcher who has closely studied the relationship between extreme heat and population health, about what extreme heat means for migrants.

Changing Climate, Changing Migration: Retreating from Climate Disaster in the United States

In Western countries, a common narrative has developed that only poor or developing nations will have to confront human displacement caused by climate change. But communities in the United States and elsewhere have repeatedly moved because of environmental disasters such as flooding. This episode features a discussion on the U.S. government’s responses to internal displacement, with Kavi Chintam and Chris Jackson, co-authors of an Issues in Science and Technology article analyzing the approach to managed retreat.

Changing Climate, Changing Migration: No “Climate Refugees,” But Still a Role for the UN Refugee Agency

Technically, people forced to move because of climate disasters are not considered “refugees.” But the UN refugee agency, the UN High Commissioner for Refugees, still takes climate issues into account, and since 2020 Andrew Harper has been its special advisor on climate action. We talked with Harper about his agency’s role in responding to climate issues, which regions of the world are most likely to be affected by climate impacts, and why climate is a “vulnerability multiplier” for refugees.

Changing Climate, Changing Migration: The Benefits of Climate Migration

Popular discussions usually frame climate change-induced migration negatively, often as a strategy of last resort. But migrating abroad can also be an effective way to build resilience against the impacts of climate change. This episode discusses how migration can bring social, economic, and other benefits to migrants and their communities, in conversation with University of Vienna human geographer Harald Sterly.

Changing Climate, Changing Migration: Is Climate Change Driving Migration from Central America?

Hundreds of thousands of migrants have left Central America in recent years, and climate extremes have been identified as one of the factors that might be driving this movement, along with elements such as political instability and violence. In this episode, we hear from geographer and climatologist Diego Pons, of Colorado State University, to dissect how changing climate, food insecurity, and migration intersect in this region.

Changing Climate, Changing Migration: Who Manages Climate Migration? Evolving Global Governance

Climate change and international migration both are global issues with aspects that countries try to manage through treaties, pacts, and other types of agreements. But most of the global governance frameworks that exist for climate-induced migration require only voluntary commitments by states. This episode features a discussion with political scientist Nick Micinski, author of the forthcoming books, UN Global Compacts: Governing Migrants and Refugees and Delegating Responsibility: International Cooperation on Migration in the European Union.

Changing Climate, Changing Migration: Migrate or Adapt? How Pacific Islanders Respond to Climate Change

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. Carol Farbotko, of Australia’s University of the Sunshine Coast and the University of Tasmania, joins the podcast to discuss the policies and dynamics in place in this region.
 
 

Changing Climate, Changing Migration: The Many Possible Futures of Climate-Linked Migration

Climate change is already affecting how, whether, and where people migrate. But environmental change is likely to become more extreme in the coming decades, unless the world takes serious action now. How might changes made now impact what future migration looks like? This 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.
 

Changing Climate, Changing Migration: How Climate-Linked Food Insecurity Shapes Migration

Reliable access to food—or lack thereof—can affect an individual’s decision to migrate. Climate change has the ability to exacerbate food insecurity, especially for farmers and others who live off the land, which can have repercussions for human mobility. In this episode we talk with Megan Carney, an anthropologist and director of the University of Arizona’s Center for Regional Food Studies, to examine the role of food security in the connection between climate change and migration.

Changing Climate, Changing Migration: Talking Money: Climate Finance and Migration

Billions of dollars are being spent on projects to help communities mitigate and adapt to the impacts of climate change, including those at risk of being displaced by environmental events. This episode features Timo Schmidt, from the Migration Policy Institute Europe, in a discussion about the growing field of climate finance and its implications for migration management and displacement prevention.
 

Changing Climate, Changing Migration: Purposeful and Coordinated: Climate Change and Managed Retreat in India

Confronting environmental change, whole communities sometimes relocate from one area to another. This purposeful, coordinated movement, while currently rare, is referred to as managed retreat. In this episode Architesh Panda, from the London School of Economics’ Grantham Research Institute on Climate Change and the Environment, explains how this climate adaptation strategy works in India.

Changing Climate, Changing Migration: One Billion Climate Migrants? Not So Fast

There are a lot of predictions about how many people will migrate in response to climate change. Depending on where you look, the next few decades could see hundreds of millions – or even more than a billion – people pick up and move. We asked Julia Blocher, of the Potsdam Institute for Climate Impact Research, to explain why the predictions vary so much. We also discussed how this movement can lead to conflict.

Does Climate Change Cause Migration? It’s Complicated

The relationship between climate change and migration is long and complex. Human civilizations have been affected by environmental conditions for centuries, but we should be wary of arguments that huge numbers of people are inevitably destined to migrate in response to specific climate threats. In this episode, we chat with Alex de Sherbinin of Columbia University’s Center for International Earth Science Information Network about what the research shows – and doesn’t show.
