Michael Poland, the scientist-in-charge of the Yellowstone Volcano Observatory, told AccuWeather last week that the volcano located under the park has erupted at least three times in the past and would “devastate much of the United States” when it erupts again.
How would Yellowstone eruption change the world?
It would kill around 100,000 people instantly and make most of North America uninhabitable as huge amounts of ash and dust would be thrown into the atmosphere. It would spark climate change that might trigger a mini-ice age due to the amount of sulphur dioxide thrown into the atmosphere and reflecting solar radiation.
