Two hundred fifty-two million years ago, a million-year volcanic siege across Siberia released a burden of carbon so immense that the oceans lost their breath, and nearly nine in ten marine species perished in what we now call the Great Dying. Scientists have confirmed that this was not merely a warming event but a metabolic collapse — life did not drown in heat so much as suffocate in waters no longer capable of sustaining it. The ancient catastrophe has returned to human attention not as a relic but as a mirror, for today's oceans are beginning to show the same early symptoms, driven this ti

Siberian Volcanoes Triggered Earth's Deadliest Mass Extinction 252 Million Years Ago
Approximately 90% of marine species were eliminated during this extinction event, representing the deadliest mass extinction in Earth's history.

Siberia (historical)
All ocean ecosystems
No direct power shift; however, this scientific confirmation strengthens climate science consensus and may influence geopolitical climate negotiations by demonstrating historical precedent for rapid CO2-driven ecosystem collapse.
Permian-Triassic extinction (252 mya) parallels current anthropogenic climate change; both involve rapid CO2 release causing ocean warming and metabolic stress, though current emissions occur 10,000x faster than Siberian volcanism.

Historical volcanic CO2 emissions caused Earth's deadliest extinction; current ocean warming patterns mirror ancient conditions, raising climate risk concerns for modern economies dependent on marine ecosystems.

Insurance and risk management
Food security and agriculture
Tourism (coastal and marine)
Consumers face potential long-term risks to seafood availability and affordability, increased insurance costs for climate-related damages, and higher food prices if marine ecosystem collapse accelerates. Households in coastal regions face elevated property and livelihood risks.
Strengthens scientific case for aggressive carbon emission regulations and climate mitigation policies. Likely to accelerate carbon pricing mechanisms, marine conservation mandates, and climate adaptation funding. May justify stricter environmental standards for industrial emissions and increased R&D investment in climate resilience.
