Empirical evidence shows that social tipping points can be triggered long before climate tipping points are reached. For example, recent research in West Africa shows that migration decisions are often based on the perceptions of environmental changes by local populations rather than on the actual observed changes . The migration of some members of a community can also trigger the migration of the whole group, as the migration of some members can have a strong impact on the community . In other contexts, the expectation of a climate impact can trigger social or political shifts: for example, the expectation of lower snow cover levers can reduce or stop investments in ski resorts. Some planned relocations of populations are already underway in anticipation of future climate impacts , while the government of Indonesia decided in 2019 to move its capital city, Jakarta, in anticipation of future floods.
