Is Yellowstone about to kill a lot of the world’s population?

Well, maybe

it’s been 600,000-ish years since Yellowstone’s supervolcano has gone off full blast…
Picture 1,000 Mount Saint Helenses…
A supereruption could kill tens of millions.
More than half the U.S. will experience ashfall, potentially fatal if inhaled.
…could devegetate a third of the lower 48 (including some of the world’s most productive farmland) for years or decades, leading to mass starvation…
Within 10 to 50 miles of the next Yellowstone vent, you’ll be Pompeiiized…
What’s the chance of a supereruption anywhere in the world in the next 50 years? Estimates range from one chance in 1,000 to one in 10,000 — hardly cause for panic.
