The obvious questions
What caused the Great Dying?
Massive volcanic eruptions in Siberia released **100,000 billion tonnes of CO₂** over a million years, triggering extreme warming and ocean chemistry shifts that wiped out **90% of marine life**.
How does this relate to today’s climate change?
Coverage highlights parallels: the extinction began with rapid ocean warming and acidification, similar to current trends linked to human CO₂ emissions.
Are modern oceans at risk of the same fate?
Researchers are investigating whether today’s marine species share the same metabolic vulnerabilities that doomed life during the Great Dying.
The story so far
Scientists have identified the primary cause of the **Permian-Triassic extinction event**, or the “Great Dying,” which occurred around **252 million years ago**. The event also disrupted ocean chemistry, causing metabolic collapse in marine life.
Coverage emphasizes the parallels between this ancient catastrophe and modern climate change. Watch for further comparisons between ancient and modern oceanic collapse indicators.
