We Didn’t Start the Fire: Paleo-perspectives on Fire in the Earth System

Session ID#: 81517

Session Description:
Since the first appearance charcoal in the Silurian, the phenomenon of wildfire has evolved alongside the Earth’s atmosphere and biosphere. Recent events have sparked great interest in the drivers and controls of fire, which is increasingly recognized as an important component of the Earth system. Paleofire records offer context with which we can assess the magnitude of observed burning, infer fire-climate relationships, and predict the impact of anthropogenic climate change. Additionally, the paleo-record provides a perspective of fire history both before and as humans became the dominant influence on global fire activity. An array of proxies, methodologies, statistical analyses, and earth system archives facilitate the paleofire approach, making it a dynamic and exciting field of study. We encourage abstracts that seek to understand the history, controls, evolution, and impacts of fire on Earth, across all temporal and spatial scales. We also welcome fire proxy developments, calibrations, and comparisons.
