Spatiotemporal Synchrony of Climate and Fire Occurrence Across North American Forests (1750–1880) Global Ecology and Biogeography

Increasing aridity has driven widespread synchronous fire occurrence in recent decades across North America. The lack of historical (pre‐1880) fire records limits our ability to understand long‐term continental fire‐climate dynamics. The goal of this study is to use tree‐ring reconstructions to determine the relationships between spatiotemporal patterns in historical climate and widespread fire occurrence in North American forests, and whether they are stable through time. This information will address a major knowledge gap required to inform projections of future fire.
