Volcanic activity plays a key role in modulating atmospheric and environmental processes. Explosive eruptions, persistent degassing, and aerosol emissions significantly influence climate dynamics. In the present, large explosive eruptions perturb the atmosphere on regional to global scales. In the geological past, Large Igneous Provinces (LIPs) were associated with major environmental changes, including mass extinctions.

Geochemical proxies (carbon, oxygen, lithium, boron) provide high-resolution records of the Earth-system response to volcanism, and modern observation techniques, such as satellites, offer advanced monitoring of volcanic emissions and climatic variables. Yet the environmental response to volcanic activity remains only partially understood.

This session focuses on forward-looking strategies that combine multi-source data, multiproxy records, real-time monitoring, and advanced modeling—including hybrid and data-driven approaches—to enhance our ability to monitor, interpret, and anticipate the climate impacts of volcanic activity, and unveil hidden mechanisms. Emphasis is placed on case studies of recent or historical major eruptions and of LIPs.
