Study Reveals Ancient Volcanoes' Role in Prolonged Past Climate Warming

Overview

• 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.
