Climate change and migration dynamics
Climate change is a new driver of human migration, and is expected by many to dwarf all other factors in its impact. But while there is growing concern about climate change, far less agreement exists about what kinds of effects will be felt where, by whom, and precisely when. Human displacement is a result of a complex mix of factors, and some of the more commonly repeated predictions of the numbers of people who will be displaced by climate change are not informed by a full understanding of the dynamics of migration. This report analyzes the salient mechanisms of displacement: sea level rise, higher temperatures, disruption of water cycles, and increasing severity of storms. It also examines the ensuing migration responses and proposes recommendations to offset the severity of displacement.
