The person I've probably quoted most when I talk about this project of Kayly Ober of Refugees International, who called climate change a "vulnerability multiplier." She meant that it exacerbates other factors, such as corruption and poverty, that make life difficult to sustain. So people we met in our reporting were all very aware of climate change. But in the same breath, they would talk about the pressures of overfishing, or the difficulty of earning a living during the pandemic. Climate change is rarely the only force in someone's decision to abandon their home, but it is often the final straw.
