Is a Supervolcano on the Way?

"The Journal of Petrology reports that an eruption from a supervolcano can be strong enough to cause change the world's climate enough to cause a mass extinction, due to the large amounts of ash that would be thrown up into the atmosphere. One of these temporarily dormant volcanoes lies beneath Yellowstone National Park in Wyoming. The last time it erupted, over 600,000 thousand years ago, half the North American continent was covered in volcanic ash."
