The Endless Winter of the Doomsday Years

Several supervolcanoes buried beneath the sea erupted day after day, sending enormous quantities of volcanic ash into the stratosphere. With little air circulation there, the ash blocked the sunlight.

Unable to penetrate the thick layer of volcanic ash, the sun's heat was completely shut out.

Within just a few days, global temperatures plunged.

Summer turned to winter.

From 40 degrees above zero, temperatures fell overnight to 10 below, 20 below, 50 below...

History would call it the Volcanic Winter.
