Radiocarbon measurements to fingerprint global change
Session ID#: 252784
Session Description:
Radiocarbon (14C) is a powerful tool in biogeochemistry, providing critical insights into carbon cycle processes and the apportionment of carbon sources in greenhouse gas and aerosol emissions. Recent advancements in accelerator mass spectrometry (MICADAS) provide opportunities for the integration of 14C with other (continuous) data streams to advance our understanding of the global carbon cycle and to develop solutions to address air pollution, land degradation, and the climate crisis.This session invites contributions from researchers utilizing high-throughput 14C analyses and those interested in long-term monitoring to: (1) Quantify how changes in terrestrial carbon cycle processes and human energy-food-water consumption affect climate change trajectories and, or air quality; (2) Differentiate fossil, biomass burning, and biogenic contributions to carbonaceous aerosol that impact climate change trajectories and air pollution; and (3) Study long-term changes in the global carbon cycle across continents, latitude bands, and through major transitions (Pleistocene/Holocene/Anthropocene).
