Changing Climate, Changing Migration

Confronting the Ethical Questions around Climate Change and Migration

Do countries that are major polluters have a moral responsibility to aid people displaced by hurricanes, sea-level rise, and other events driven or exacerbated by climate change? What form might that responsibility take? For this episode, we are joined by Jamie Draper, who focuses on political philosophy and ethics at Utrecht University. While he argues that certain countries do have a responsibility to aid displaced people, labeled “climate migrants” by some, in his view that does not necessarily translate to offering them protection.

Could a Loss and Damage Fund Compensate Climate Migrants?

The world is grappling with the idea of restitution for people who have been negatively affected by the impacts of climate change—potentially including displacement within a country or across international borders. World leaders are at the early stages of creating a global loss and damage fund to financially compensate these climate victims. Much remains unresolved, including complicated and controversial questions about which countries owe money to whom, and how to attach a dollar figure to intangible losses such as destruction of natural land. In this episode, we speak with Adelle Thomas from Climate Analytics to wade through the thicket of challenges ahead, in particular as relates to climate migrants—those displaced by hostile environmental conditions linked to a rapidly changing climate.

Moving Mountains: Climate Migration in High Altitudes

Many people are leaving rural mountain areas around the globe because their livelihoods are becoming less profitable and the threat of landslides and other disasters is increasing. As the impacts of climate change grow, these mountain residents may face additional challenges dealing with environmental disruption. And by moving to urban areas, they may face a new set of issues and lose connection with their homelands. In this episode, we speak with Amina Maharjan from the International Centre for Integrated Mountain Development about the unique climate migration issues that are witnessed in mountain regions.

Are the Pacific’s Climate Migration Experiments a Preview for the World?

A landmark climate migration deal inked in late 2023 would allow hundreds of climate-vulnerable residents of the small island nation of Tuvalu to move to Australia. The pact is the latest step for a region that is at the leading edge globally in policy experimentation to address climate displacement. This Australia-Tuvalu deal, which is not uncontroversial, follows a brief and ultimately shelved attempt by New Zealand to create a “climate refugee” visa. How are these policies playing out, and what can the rest of the world learn from the Pacific experiences? This episode features renowned legal scholar Jane McAdam, who directs the Kaldor Centre for International Refugee Law at UNSW.

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.

Is Climate Migration a Homeland Security Threat?

Can climate-driven international migration pose a security threat? Former U.S. Homeland Security Secretary Michael Chertoff thinks so, but not necessarily because of the migrants themselves. Irregular migration prompted by climate events can empower smugglers and criminal groups. And it can spur an extremist backlash in receiving countries if people feel their government is not adequately protecting them. Chertoff talks about the security implications of climate change and migration in this episode of the podcast.

Trapped Populations: When Climate Migration Isn’t Possible

Facing the adverse impacts of climate change, many people are better off migrating, whether within their country or internationally, at least for a short time. Yet for a variety of reasons, migration is not always possible. This episode of our podcast focuses on these groups, sometimes known as “trapped populations.” Why do people stay in places where their homes, livelihoods, and their very lives are threatened? We explore these questions with Caroline Zickgraf, deputy director of the Hugo Observatory at the University of Liège in Belgium.

Climate Migration 101

Climate migration sounds simple. It’s not. This episode of the podcast speaks with Lawrence Huang, MPI’s lead researcher on climate change and migration, to answer the most common questions around one of the least understood dynamics in human movement. Read an article on this topic from Lawrence here: "Climate Migration 101: An Explainer."

Before the Storm: Getting Out in Front of Climate Displacement

Humanitarian organizations often race to help people affected by natural disasters. But what if they could act before catastrophes occur to mitigate disaster-induced forced migration? In this episode, we discuss this kind of anticipatory action and how it might reduce chaotic displacement. Our guests are Gana Gantulga and Zeke Simperingham from the International Federation of Red Cross and Red Crescent Societies.

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.
