65 Million Years ago, an asteroid impact caused a cascade of catastrophes that led to the downfall of the dinosaurs, but what would happen if the same size space rock struck near the same spot again? How would modern humans cope with a hailstorm of falling rocks and debris, mega tsunamis, out of control fires, blast-furnace temperatures, and a destroyed ozone layer? In the wake of worldwide destruction, who would survive...and who would perish?

Ocean currents control the climate around the world. When they suddenly stop, it unleashes an endless cascade of weather disasters, including blizzards, superstorms, wildfires, widespread drought, and rapid sea level rise. No place on earth is spared from this climate catastrophe that threatens to end human civilization.
