- New research highlights the importance of tropical forests in preventing prolonged global warming.
- The Permian-Triassic Mass Extinction, or 'Great Dying,' led to massive loss of marine species and terrestrial plants and animals.
- Intense global warming during the event was triggered by volcanic activity in Siberia, known as the Siberian Traps.
- The collapse of tropical forests limited carbon sequestration, leading to prolonged high CO2 levels.
- Researchers used fossil records and rock formations to reconstruct changes in plant productivity during the extinction.
- Findings suggest thresholds in Earth’s climate-carbon system can amplify warming when crossed.
- China’s geological record provided crucial data for the study, gathered over decades by Chinese geologists.
- Simulations confirm that loss of tropical vegetation aligns with subsequent warming patterns.
- Current tropical forest collapse could similarly prevent climate cooling even if CO2 emissions stop.
- The study underscores the need for interdisciplinary approaches to understand and mitigate climate change.
