Outgassing has played a fundamental role in forming and altering Earth’s atmosphere and climate, and, therefore, habitability throughout its history. From cataclysmic global outgassing events as LIP emplacements or the Great Oxidation Event to regional and local outgassing processes, the release of volatiles can drive both short- and long-term environmental perturbations and pose significant hazards to the biosphere. Beyond Earth, outgassing remains a key process influencing the evolution of other planetary bodies in our solar system, as demonstrated by volcanic activity on Venus or cryo-volcanism on a multitude of planetary bodies.
This session invites interdisciplinary contributions from geochemistry, planetary science, and geodynamics to advance our understanding of outgassing processes. We aim to explore the variability of outgassing and its role in past and present climate change, and its broader planetary implications. By integrating perspectives from Earth and planetary sciences, we welcome abstracts based on numerical, analytical and laboratory work in this interdisciplinary session.
