Michael Dickison at the Herald has a great article on the Apocalypse.
The top 5 scenarios for the end of the world as we know it
Remember Independence Day? Astrophysicist Craig Kasnov recently announced that three very large, fast-moving objects were approaching Earth. Though largely discounted by others, the SETI (Search for Extraterrestrial Intelligence) researcher Kasnov said the “flying saucers” were tens of kilometres long and would arrive mid-December.
How to prepare: Some say you should head to the French Pyrenees, from where you may be beamed up and rescued.
2) Natural disaster
Supervolcanoes cause mass extinction. The most recent occurred in New Zealand about 26,000 years ago, while a likely site for the next eruption is Yellowstone National Park, in the United States.
How to prepare: Leave the Pacific’s Ring of Fire, preferably for equatorial Africa, where humans survived the last volcanic winter.
3) Nuclear attack
Surviving the initial horror of thermonuclear war is just the beginning. A nuclear winter will follow as debris, smoke and soot block sunlight for weeks or even years, and then there’s radiation sickness, lawlessness and the breakdown of civilisation to worry about.
How to prepare: For a quick end, stand outside as the bombs fall. Otherwise, build an underground bunker with enough supplies, guns, clothing, etc, to survive in the Mad Max-style post-apocalyptic wasteland.
4) The god of war cometh
Bolon Yokte, a Mayan deity, is prophesied to return to Earth in 2012, although key passages on a stone tablet containing the prophesy have eroded away.
The god may cause huge chaos and upheaval – or bestow upon people the energy to take an evolutionary step.
How to prepare: Only human sacrifice can save us now.
Biblical messianic prophesies suggest a Second Coming of Jesus, possibly including resurrection of the dead. Armageddon is often associated with such an event.
How to prepare: Watch Supernatural from series three onwards. And pray a lot.
The entire article is hilarious.
