Doomsday: 10 Ways the World Will End

How humans might cope with falling rocks and debris, tsunamis, furnace-like temperatures, and fires in the aftermath of a killer asteroid; 65 million years ago, an asteroid led to the downfall of the dinosaurs.

As it approaches Earth, a black hole would trigger earthquakes, volcanic eruptions and tsunamis.

If a rogue planet was on a collision course with Earth, its gravity would tear apart the Moon, stir up supersonic winds, trigger earthquakes, and pull the Earth to pieces.

A solar storm turns Earth's electrical system into a smoking ruin, and modern civilization must cope without power.

During a nuclear war, hydrogen bombs destroy the world's greatest cities; a fallout of ash and debris creates a nuclear winter, plunging the planet into an ice age; crops fail and mass starvation drives humanity to the brink of extinction.

A gamma-ray burst from two colliding stars hits the atmosphere, wiping out half of the population on Earth, while the other half faces a slow death from ultraviolet radiation and starvation.

After a volcanic hyper eruption blows through the surface of the Earth, molten rock slams into cities, shock waves bring down buildings, volcanic gas blocks out sunlight, food chains collapse, and a famine threatens the future of humankind.

A scenario in which Earth is pulled out of its orbit, sending it on a collision course with the sun and triggering massive hurricanes, sandstorms and a deadly heat wave.

A deep sea disaster unleashes a cascade of weather catastrophes, including blizzards, super storms, wildfires, drought, and rapid sea-level rise.
