Burning coal in Siberia ignited by volcanic eruptions led to catastrophic global warming that caused the Earth’s most severe extinction event 250 million years ago
Burning coal may have been to blame for a catastrophic global warming event 250 million years ago that wiped out 96 per cent of marine and 70 per cent of terrestrial species on Earth.
For years it has been attributed to extensive volcanic eruptions in Siberia over two million years, which belched tons of carbon dioxide into the atmosphere.
But now scientists have uncovered evidence that the boiling lava ignited coal seams buried in the Earth, which released more greenhouse gases and exacerbated the disaster.
