Session Proposal: Paleo- and Historical Perspectives on Fire in the Earth System (AGU25)

PP024
Paleo- and Historical Perspectives on Fire in the Earth System

Session ID#: 247491

Session Description:
Wildfire has evolved as part of the Earth System since the Silurian and interacts with the atmosphere, biosphere, cryosphere, and geosphere via complex and ever-changing relationships. The impacts of recent extreme wildfires and the predicted effects of climate change have together sparked greater interest in the drivers and controls of fire. Paleofire and historical records offer context with which we can assess the magnitude of observed burning, infer fire-human-climate relationships, and predict the impact of fire on ecosystem dynamics. Further comparisons of empirical data with climate and fire models provide additional perspective on past, current, and future wildfire drivers, behavior, and impacts. We encourage abstracts that seek to understand the history, controls, and impacts of fire across all temporal and spatial scales, using all archives, proxies, methodologies, and statistical analyses. We also welcome fire proxy developments, calibrations, and multi-proxy comparisons as well as paleofire modeling and proxy-model comparisons.
