Could Yellowstone Destroy America?

In the event of a massive Yellowstone super eruption, the effects would be devastating, but it would not literally wipe the United States off the map. A huge eruption could send enormous amounts of ash across much of North America. Areas around Yellowstone could be buried by superheated volcanic flows, while ash could disrupt roads, airports, power supplies, water systems, and agriculture hundreds or even thousands of miles away. The eruption could also affect the climate by sending sulfur and other particles high into the atmosphere, temporarily reducing sunlight and lowering temperatures around the world. Food production could suffer, creating serious economic and humanitarian problems. But there is an important catch. A Yellowstone super-eruption is extraordinarily unlikely in the foreseeable future. Scientists currently see no signs that one is approaching. So while a super eruption could cause a nationwide and potentially global disaster, it would not mean the end of America or humanity.
