Pathways for climate change effects on fire : models, data, and uncertainties

Auteur(s) et Affiliation(s)



Description :
The A. reviews recent model-, empirical-, and fire history-based studies of fire and climate change and proposes 3 pathways along which fire regimes might respond to climate change: changes in fuel condition, fuel volume, and ignitions. Model- and empirical-based studies have largely focused on changes in fuel condition with some models projecting up to 50% increases in area burned under a 2 x CO2 climate. Fire history data derived from tree-rings, sediment charcoal, and soil charcoal have helped identify past trajectories of change in fire regimes and can point to possible future conditions. However, most fire history research has focused on changes in area burned and fire frequency. Changes in fire severity may be equally important for the earth system. Critical research needs include next generation dynamic vegetation models (DGVMs).
