Wildfire has evolved as part of the Earth System since the Silurian. Fire 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 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. Paleo-records provide perspectives of fire history both before and as humans became the dominant influence on global fire activity. These comparisons can be used to assess current wildfire drivers, behavior and impacts. An array of proxies, methodologies, and statistical analyses facilitate the paleofire approach. We encourage abstracts that seek to understand the history, controls, and impacts of fire across all temporal and spatial scales. We also welcome fire proxy developments, calibrations, and comparisons.
