Two recent explanations for the Paleocene-Eocene Thermal Maximum (PETM)
Oxytropidoceras posted a topic in Fossil News
Orbit of Doom: The Surprising Connection Between Earth’s Orbital Patterns and an Ancient Warming Event, SciTechDaily, Pennsylvania State University, January 15, 2023 The open access paper is: Li, M., Bralower, T.J., Kump, L.R., Self-Trail, J.M., Zachos, J.C., Rush, W.D. and Robinson, M.M., 2022. Astrochronology of the Paleocene-Eocene Thermal Maximum on the Atlantic Coastal Plain. Nature communications, 13(1), pp.1-13. Another explanation for the PETM is: New imaging finds trigger for massive global warming 56 million years ago 56 million years ago, hot magma scorched the sediments under the Atlantic seafloor. Howard Lee, ArsTechnica, January 13, 2023 The open access publications are: Jones, S.M., Hoggett, M., Greene, S.E. and Dunkley Jones, T., 2019. Large Igneous Province thermogenic greenhouse gas flux could have initiated Paleocene-Eocene Thermal Maximum climate change. Nature Communications, 10(1), pp.1-16.
