Public Opinion of Climate Migrants: Understanding What Factors Trigger Anxiety or Support
Related Content
Highlights
Public support for climate migrants is fragile and can decline when movement seems unmanaged, permanent, or likely to strain climate-affected host communities.
- Polls show climate migrants do not automatically attract more public support than other migrants; studies in Germany and the United States found only a 4 to 8 percentage point preference, with refugees seen as most deserving.
- Support is strongest when displacement appears sudden and temporary. As climate impacts blur the line between short-term and permanent movement, publics may grow anxious if newcomers compete for scarce resources.
- Alarmist narratives heighten fears of disorder, victimhood narratives can amplify communities’ own climate anxieties, and overly optimistic narratives may backfire if they downplay real trade-offs.
- Policymakers should be selective about invoking climate migration, focus on concrete steps rather than blame, acknowledge migration’s costs alongside benefits, and invest in resilience for local residents and migrants alike.
Climate change and extreme weather events are predicted to dramatically alter patterns of human mobility around the world. This poses an urgent policy question: How will receiving communities react to the arrival of people displaced by disasters and climate impacts? The degree of public support for newcomers can shape how policy responses are designed, implemented, and received by the public.
But public opinion is not always easy to predict, nor is it static or fixed. A review of polling and experimental data from around the world suggests that climate migration may trigger anxiety if accompanied by a sense of disorder, unfairness, or loss of control, but also that communities can rally to support large displaced populations, given the right conditions. Efforts to increase support for climate migrants often draw on common narratives—of urgency, of climate migrants’ victimhood, or of their ability to make positive contributions to climate action—but these all come with their own risks and trade-offs.
This issue brief looks at what is known about public opinion of climate migrants, and what lessons can be gleaned from broader efforts to mitigate public anxiety and build welcoming communities in the context of rapid societal change. It reflects on how common narratives can create environments more or less welcoming of climate migrants, and how they shape the space policymakers have to think creatively about how to manage climate migration.
