Watch Doomsday: 10 Ways the World Will End

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.

Rogue aliens launch a surprise attack on Earth, destroying cities, destroying world governments and unleashing a deadly virus.

Earth is pulled out of its orbit, sending it on a collision course with the sun and triggering massive hurricanes, sandstorms and a deadly heatwave.

For the first time in human history, a volcanic hyper eruption blows through the surface of the Earth. Explosive shock waves tear apart buildings, molten rock slam into cities, and a deafening sound circles the globe. A bad day for Planet Earth gets worse as volcanic gas blocks out sunlight, food chains collapse, and epic famine threatens the very future of mankind.

The most powerful blast of cosmic radiation in the Universe is just seconds from slamming into Planet Earth. When a gamma ray burst from two colliding stars hits the atmosphere, the deadly radiation delivers agonizing death and immediately wipes out half the planet.

World War 3 breaks out and a nuclear nightmare becomes reality as thousands of hydrogen bombs destroy the world’s greatest cities. A deadly fallout of ash and debris creates a Nuclear Winter, plunging the planet into a sudden Ice Age. Crops fail worldwide and mass starvation drives humanity to the brink of extinction.

When Earth gets hit by a deadly Solar Storm a massive chunk of the Sun our planet's electrical system turns into a smoking ruin. How does modern civilization cope without power?

There are twice as many rogue planets as stars in the galaxy. So what might happen if a ringed planet the size of Neptune were on a collision course with Earth? Within a period of just four hours, as people flee in panic, the gravity from the rogue planet would tear apart the Moon.

Human civilization is under attack from a catastrophic--but unseen--threat from space. A supermassive black hole is moving toward Earth at almost the speed of light. As this celestial killer approaches our planet, its enormous gravitational forces trigger earthquakes, volcanic eruptions, and tsunamis larger than any the world has ever seen.

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.
