This Firescience.gov report describes the likely impacts of 21st Century climate change on fire management, and will help managers plan for fire under rapidly changing climate conditions. The authors describe basic concepts of climate science and explain the causes of accelerating 21st Century climate change. Fire regimes and ecosystem classifications serve to unify ecological and climate factors influencing fire, and are useful for applying fire history and climate change information to specific ecosystems.
