The Siberian Traps: A 250 Million Year Old Crime Scene

The video explores the Permian mass extinction, known as the Great Dying, which occurred 252 million years ago. It highlights the role of the Siberian Traps, a volcanic region in Russia, in this event. The eruptions released massive amounts of greenhouse gases, altering Earth's climate and leading to the extinction of over 90% of species. The video discusses various hypotheses, focusing on the impact of contact metamorphism, which released more carbon dioxide than the eruptions themselves. This research provides insight into the causes of the most significant extinction event in Earth's history.
