When It Rained for 2 Million Years

234 million years ago, Earth entered one of the strangest climate events in its history. For roughly two million years, Pangaea was hit by repeated waves of extreme rainfall during an event known as the Carnian Pluvial Episode. Deserts turned into swamps, rivers carved new paths across the land, forests changed, oceans lost oxygen, and entire ecosystems were reshuffled. But the most important consequence may have been what happened next. Before the rain, dinosaurs were still relatively minor players. Rhynchosaurs, dicynodonts, and powerful croc-line predators dominated much of the land. After the climate shifted, dinosaurs began appearing in far greater numbers, while new conifer forests and changing food supplies opened ecological opportunities that had barely existed before. In this video, we explore what caused the Carnian Pluvial Episode, how volcanism and greenhouse gases may have supercharged the water cycle, why the rain came in repeated pulses, what happened to life in the oceans, the incredible amber fossils preserved from the event, and how this forgotten climate upheaval may have helped set the stage for the rise of dinosaurs. From tiny early dinosaurs like Eoraptor, Staurikosaurus and Buriolestes to the first giant sauropodomorphs, this is the story of how a two-million-year rainstorm helped reshape the future of life on Earth.
