Climatic, environmental and societal impacts of volcanic eruptions
Session ID#: 157120
Session Description:
Volcanic eruptions can significantly alter the Earth's radiation budget and cause climate perturbations on interannual to multidecadal time scales. Ultimately, they may influence the biosphere and local and regional environments as well as societies. Our understanding of volcanic impacts on climate remains hampered by the paucity of observed eruptions, uncertainties in volcanic forcing datasets, limitations of proxy-based climate evidence, uncertainties of global aerosol model simulations and inconsistencies of responses across climate models. Also, how volcanic forcing will affect future climates remains uncertain. This session aims at bringing together researchers studying the impact of volcanic eruptions on climate variability and predictability by means of observations, climate reconstruction studies, and modeling. We aim to highlight contributions conducted under the umbrella of CMIP6, especially the VolMIP and PMIP4 activities, contributions aligned with the PAGES-VICS working group and with the SPARC SSiRC activity.
