During the eruption of Mount Pinatubo in June 1991, large quantities of ash particles were ejected into the stratosphere. The eruption’s impact on the climate lasted for years. (Bild: Dave Harlow, USGS)

Volcanoes acted as a safety valve for Earth’s long-term climate

How do you know where volcanic ash will end up?

Rock samples collected near the Antarctic volcano Mount Erebus, seen here in the distance, harbor fingerprints of Earth’s ancient magnetic field. A new analysis delves into discrepancies between these fingerprints and predictions from a long-standing approximation of the field. Credit: Hanna Asefaw
