The rising tide no one’s talking about—finding homes for millions of climate crisis migrants

When it comes to the climate crisis, there’s barely a day that goes by when we don’t hear about the impending effects of rising sea levels and storm-driven tides. But Harvard professors Jaqueline Bhabha and Hannah Teicher say there’s another rising tide that’s not getting as much attention, despite its potential to reshape our world. It’s the wave of climate migrants—people who have been and will be driven from their homes by rising seas, extreme heat, catastrophic weather, and climate-related famine and economic hardship. Some will try to relocate within their home countries, others across international borders, but most experts predict that there will be hundreds of millions of them. In fact the United Nations says hundreds of millions of people globally have already been forced to relocate for climate-related reasons, and experts say as many as a billion people could be seeking new homes by 2050. Meanwhile, immigration is already a political third rail in many countries, including the United States, and has driven a rise in both authoritarianism and ethnonationalism. So where will they go? And what kind of welcome will they receive when they get there? Bhabha and Teicher are working on those questions, examining everything from the language we use when we talk about climate migration to international law and human rights to urban planning policies that can help create win-win situations when newcomers arrive. They say major changes to our climate and to the earth’s habitable spaces are coming, and a large part of adjusting to that successfully will involve another difficult change—to our way of thinking about how we share the world with our fellow humans.

Jacqueline Bhabha is a faculty affiliate of the Carr Center for Human Rights Policy at Harvard Kennedy School, director of research for the FXB Center for Health and Human Rights, a professor of the practice of health and human rights at the Harvard T. H. Chan School of Public Health, and the Jeremiah Smith Jr. Lecturer in Law at Harvard Law School. From 1997 to 2001 Bhabha directed the Human Rights Program at the University of Chicago. Prior to 1997, she was a practicing human rights lawyer in London and at the European Court of Human Rights in Strasbourg. She has published extensively on issues of transnational child migration, refugee protection, children's rights and citizenship. She is author of Child Migration and Human Rights in a Global Age, and the editor of Children Without A State and Human Rights and Adolescence. Bhabha serves on the board of directors of the Scholars at Risk Network, the World Peace Foundation, and the Journal of Refugee Studies. She is also a founder of the Alba Collective, an international NGO currently working with rural women and girls in developing countries to enhance financial security and youth rights. She received a first class honors degree and an M.Sc. from Oxford University, and a J.D. from the College of Law in London.

Hannah Teicher is an assistant professor of urban planning at Harvard University’s Graduate School of Design. Her research is broadly concerned with how mitigation and adaptation to climate change are shaping urban transformations across scales. Her current research explores how receiving communities for climate migrants can learn from other forms of relocation to address tensions between host communities and newcomers. She is interested in how local level planning will grapple with the confluence of adaptation and migration as well as how urban restructuring will evolve at national and transnational scales. For the Climigration Network, Teicher co-chairs the Narrative Building Work Group which guided development of Lead with Listening, a guidebook for community conversations on climate migration. She is also an active member of the American Society of Adaptation Professionals. She holds a PhD in Urban and Regional Planning from MIT, a Master of Architecture from the University of British Columbia, and a BA in Sociology and Anthropology from Swarthmore College.
