ESD Ideas: Cenozoic Ice Volume as a Driver of Geomagnetic Events
Abstract. This study investigates the relationship between Cenozoic ice volume changes and geomagnetic events, including reversals and incomplete reversals, revealing that high frequencies of these events responded to ice volume increases over the past 49 million years. Geomagnetic events forming chrons or wiggles shorter than 0.1 Myr are particularly sensitive to ice volume changes. The findings suggest that future global warming could suppress geomagnetic activity, highlighting the impact of climate-driven ice volume changes on Earth's magnetic field dynamics.

Short summary
This study examines how changes in Earth's ice volume influence geomagnetic events, such as reversals and incomplete reversals, over the past 49 million years. We find that increased ice volume correlates with more frequent geomagnetic events, while rapid ice sheet melting under future warming could reduce their occurrence. These findings enhance our understanding of Earth's magnetic dynamics and their potential link to climate change.
