It will kill us all.
The earth will go into a deep freeze, just like Toba.
"The Youngest Toba eruption was a supervolcano eruption that occurred around 74,000 years ago[1] at the site of present-day Lake Toba in Sumatra, Indonesia. It is one of the Earth's largest known explosive eruptions. The Toba catastrophe theory holds that this event caused a severe global volcanic winter of six to ten years and contributed to a 1,000-year-long cooling episode, leading to a genetic bottleneck in humans.[2][3]"
The sky will fall!!!
