Changing Climate, Changing Migration

Under the right circumstances, climate-induced migration can aggravate the drivers of violent conflict. In places such as the Middle East and West Africa’s Sahel region, migration during times of environmental precarity can upset delicate social and demographic balances and place additional pressure on local authorities. Left to fester, the results can be deadly. This episode explores this connection between climate change and huma...

Floods, drought, extreme temperatures, and other climate events have devastated parts of Afghanistan and Pakistan. Repercussions of climate change come on top of years of conflict, which have left countless numbers of people unable to adapt to changing conditions. In response, many have fled, either in short-term displacement or permanent migration. Our podcast speaks with researchers Maryam Abbasi and Nasrat Sayed about how climat...

Natural disasters and other impacts of climate change are already affecting migration, but often in complex ways. This episode, we speak with Julia Neusner, a lawyer and researcher with the International Refugee Assistance Project. She has conducted surveys and interviews with migrants at the U.S.-Mexico border about whether, where, and how they have experienced climate impacts, and offers some of their stories here. More than 40 p...

Many countries need more workers to fill jobs in clean energy and other sectors that are critical in the fight against a warming planet. Immigrants may be one part of the solution to the challenges posed by climate change. But governments have been slow to ramp up responses to recruit, train, or accredit foreign-born workers necessary for the green transition, with one model estimating a shortage of 7 million green workers globally...

The international humanitarian protection system that was built in the aftermath of World War II does not offer protection for people displaced by climate change. In this episode, former UN Deputy High Commissioner for Refugees T. Alexander Aleinikoff, who is now Executive Dean of The New School for Social Research, calls the refugee system “broken.” Rather than expanding to accommodate “climate refugees,” he makes the case for sta...

The ways in which people talk about climate migration can affect how individuals are treated. While many activists frame climate migrants as blameless victims of circumstance and even refer to them as “climate refugees,” this approach does not always lead to public sympathy. Moreover, highlighting the role of climate in displacement can unintentionally cause a backlash among host communities, who themselves likely are experiencing ...

The Arctic region is warming much faster than other parts of the world. Nordic countries—Denmark, Finland, Iceland, Norway, and Sweden—have a reputation for being at the forefront of efforts to combat climate change. But does their track record also extend to helping people who have been displaced by environmental impacts, internally and internationally? In this episode, we discuss the impacts and responses in the Nordic region. Ou...

Climate change is remaking vacations, particularly in hot months. Extreme heat can be deadly for tourists and events such as wildfires, hurricanes, and sea-level rise can devastate tourism-dependent communities. Tourism is also a major contributor to climate change, and some travelers have begun rethinking their plans, taking emissions into account as they consider transportation and destinations. This episode explores how climate ...

The U.S. military has long warned that climate change poses a challenge to global security. Instability and insecurity can be a result of unmanaged migration, with the potential for widespread climate displacement creating tensions in host communities. And they could also spark additional migration, if people flee precarious political dynamics. This episode, with Climate Migration Council member and retired U.S. Navy Pacific Fleet ...

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, labele...

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 coun...

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 episod...

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 “...

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-Re...

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 s...

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 q...
