PP018:
Evaluating Tectonic Forcings on the Long-Term Carbon Cycle





Session ID#: 24413

Session Description:
Fluxes of CO2 into and out of the atmosphere via the long-term carbon cycle play first-order roles in dictating Earth’s baseline climate state. Ongoing debates continue to circulate over which aspects of the carbon cycle exert the ‘dominant’ controls responsible for major climatic shifts in Earth History. Specifically, the community lacks consensus on whether shifts between greenhouse and icehouse states are primarily driven by changes of carbon inputs into the atmosphere from volcanic outgassing or changes in the global carbon sinks, either silicate weathering processes and organic matter burial.  This session will highlight novel approaches that investigate how variation in the principal COsources and sinks influence long-term climate change. We encourage submissions that provide perspectives from diverse studies utilizing geochemical archives, carbon cycle and Earth systems modeling, and/or integrative field-based assessments of the geologic record to understand the fundamental causes of climatic transitions throughout Earth history.
