Study Reveals Ancient Volcanoes' Role in Prolonged Past Climate Warming

Research uncovers how hidden carbon emissions from ancient magma fields extended warming periods long after volcanic eruptions ended.

Massive magma fields under ancient volcanoes continued to release carbon dioxide, contributing to extended global warming periods in Earth's history.
The study focuses on the Permian period's mass extinction event 252 million years ago, where volcanic activity in Siberia was a major factor.
Despite the cessation of surface eruptions, magma in the Earth's crust and mantle kept emitting carbon dioxide, delaying climate recovery by millions of years.
This hidden source of carbon dioxide offers insights into how Earth's climate was disrupted and eventually stabilized after major volcanic events.
Current human-induced carbon emissions far exceed volcanic contributions, but understanding past events may inform future climate recovery strategies.
