Near the top of the supercontinent Pangaea in what is now Siberia, a gigantic plume of magma—enough to cover the lower 48 states a kilometer deep—was burbling through one of the most coal-rich regions in the world and covering millions of square miles of Pangaean countryside in basalt lava. As the molten rock ponded underground, seeping sideways into the crust, it incinerated not only untold seams of coal laid down by ancient forests in the hundreds of millions of years before, but huge deposits of oil and natural gas as well. The ignited oil and gas exploded at the surface, leaving behind half-mile craters. The volcanoes injected as much as 40,000 gigatons of carbon into the atmosphere. This unthinkable volcanism, and the greenhouse gases it liberated, account for the extreme global warming and ocean acidification seen in the rocks spanning the dreaded Permian-Triassic boundary. It’s even been called The Great Dying.
