Global heating is compounding threats for people already living with conflict and insecurity, further driving displacement around the world. In 2019, weather-related hazards triggered some 24.9 million displacements in 140 countries around the world. Most displacement linked to climate change is taking place within national borders. People fleeing extreme weather events such as hurricanes, cyclones and floods, for example, tend to stay as close to home as possible and return when floodwaters have receded. Lengthier displacements and movement across international borders are more likely when additional factors are at play.
