As fires rage in Australia and in the Amazon, hurricanes ravage the Caribbean year after year, and glacial melt threatens entire communities in the high mountains of Asia and Europe, peace and climate activists might be forgiven for experiencing a growing sense of dread. Environmental events of this magnitude have the potential to simultaneously trigger new ecological disasters and strain social and political systems. The unprecedented challenges borne of the climate crisis will be far-reaching, from large-scale involuntary migration and food and water shortages, to biodiversity and ecosystem loss. These challenges require responses that build social cohesion rather than fuel conflict—responses that are collaborative, just, and climate-resilient.
