The video discusses the potential eruption of the Yellowstone supervolcano and compares it to the Toba supervolcano eruption 75,000 years ago. The Toba eruption had a significant impact on the global climate and human evolution, possibly causing a genetic bottleneck. However, recent studies question the extent of its climatic effects. The Toba eruption was one of the largest known, with a volcanic explosivity index of 8, releasing massive amounts of ash and sulfur dioxide, forming Lake Toba.
