GC43L:
The Role of Fire in the Earth System: Understanding Drivers, Feedbacks, and Interactions with the Land, Atmosphere, and Society I

Submit an Abstract to this Session



Session ID#: 32591

Session Description:
Anthropogenic and natural fires are an important component of the Earth system. Geographic location, fuel type, seasonality and intensity of fire largely determine the sign and magnitude of feedbacks on the Earth system. The aim of this session is to explore links between fire, vegetation, climate, and humans from the local to the global scale and determine how these interactions will change in a warming world. We encourage abstracts that explore the interactions of fires with the terrestrial biosphere and atmosphere using remote sensing, in situ observations, modeling, or an integrated approach with an emphasis on (1) impacts of fire on weather and climate, atmospheric chemistry and air quality, (2) the role of fires in the carbon cycle and ecosystem functioning, (3) the influence of humans on fire (and vice versa), and (4) the changing nature of fire over millennia, and predictions for the future.
