A monster volcano underneath Yellowstone National Park may erupt sooner than expected and drive the Earth into a volcanic winter, scientists say. The sleeping supervolcano could develop the conditions it needs to erupt within a few decades, Arizona State researchers found. Previously, geologists thought it would take centuries for the volcano to be ready to blow again after a major explosion.
