Catastrophe

250 million years ago, 95% of life was wiped off the face of Earth in the biggest extinction event ever. But what was responsible? Back then, our planet was a very different place. Millions of years before the era of dinosaurs, creatures such as dicynodonts and gorgonopsians roamed the land, while the oceans too teemed with life. Then, in the blink of a geological eye, everything changed. Life itself was almost completely wiped out in what is known as the Permian extinction.

Travelling to locations such as South Africa, California, and Iceland, the experts discover that the volcanic activity of the Siberian Traps led to the release of deadly gases from beneath the sea and rises in Earth's temperature. This turbocharged global warming brought drought and a breakdown in the food cycle, with even the strongest animals eventually succumbing to the conditions.
