Around 252 million years ago, volcanoes across what is now Siberia erupted repeatedly for more than a million years, releasing perhaps 100,000 billion tonnes of carbon dioxide and helping wipe out roughly 90 per cent of marine species in the deadliest mas

Researchers have concluded that a series of eruptions across present‑day Siberia began about 252 million years ago and lasted for more than a million years. The eruptions released perhaps 100,000 billion tonnes of carbon dioxide, a volume linked to the loss of roughly 90 percent of marine species in what is now called the Great Dying, Earth’s deadliest mass extinction.

Coverage from Gizmodo, ScienceDaily, Open Access Government and the Stanford Doerr School of Sustainability stresses that the findings solve a long‑standing mystery about the extinction’s cause. Resilience.org and the Economic Times draw a parallel to today’s climate trajectory, warning that modern oceans already show signs reminiscent of the ancient event.

Future reporting is expected to track how scientists monitor current oceanic changes for extinction signals and to explore the metabolic vulnerability identified as a key factor. Follow‑up studies may examine policy implications of the volcanic‑CO₂ analogy.
