This briefing by the Environmental and Energy Study Institute argues that the United States must proactively plan for climate-induced migration to avoid regional instability and humanitarian crises. It highlights the lack of legal protections for environmental migrants and the specific risks of agricultural decline in Mexico and Central and South America, while noting the potential strain on U.S. military resources tasked with humanitarian aid.

This research paper examines the complex relationship between anthropogenic climate change and forced human migration. It challenges simplistic predictions of mass migration, arguing that displacement is driven by a combination of climate processes (slow-onset changes) and climate events (sudden hazards), mediated by non-climate factors such as governance, poverty, and adaptive capacity. The author outlines three speculative scenarios for future migration based on IPCC emission storylines and discusses the significant development implications for the poorest countries, which are expected to bear the greatest burden of providing for climate migrants.
