Will the Yellowstone supervolcano erupt in our lifetime?

"As with many things in nature, it helps to understand the past when trying to predict the future.
Ilya Bindeman, an associate professor of geological sciences at the University of Oregon, believes this is true of the Yellowstone supervolcano and the likelihood that it will produce an apocalyptic eruption as it has three times over the last the last 2 million years.
"Yellowstone is one of the biggest supervolcanos in the world," he says. "Sometimes it erupts quietly with lava flow, but once or twice every million years, it erupts very violently, forming large calderas," which are very large craters measuring tens of kilometers in diameter.
If it happens again, and he says most scientists think that it will, he predicts such an eruption will obliterate the surroundings within a radius of hundreds of kilometers, and cover the rest of the United States and Canada with multiple inches of ash. This, effectively, would shut down agriculture and cause global climate cooling for as long as a decade, or more, he says. A volcanic event of such magnitude "hasn't happened in modern civilization," he says.
