Donald Trump caused a Doomsday Clock symbolising the threat of apocalypse to move closer to midnight yesterday.
The new 'time', two and a half minutes to midnight, is the closest the planet has been to an apocalypse since 1953 - mainly due to the threat of climate change or nuclear warfare.
Now, in light of the change, millions of people have been trending explaining how to survive a nuclear attack, and some of the best tips for surviving a nuclear attack have been revealed.

PACK AN EMERGENCY SUPPLY KIT
The pair advises packing an emergency supply kit containing water and non-perishable food items.
When a nuclear bomb goes off, it sends out radiation that can ruin your mobile phone and laptop, so preparing battery-powered radios for communication is essential.
Experts expect electronic devices thousands of miles away could be affected by the electromagnetic pulse sent out by a bomb.
FIND A SHELTER
Shelters are the next important safety step.
'There's a difference between a blast shelter and a fall-out shelter,' says Gregory Brown.
For the blast, it is important to get as much concrete between you and the blast as possible.
In a house, go to the basement, and in a high-rise, get to the middle of the building away from windows.
For the fall-out it's important to have thick walls and a thick roof, he says, and in a house it is a good idea to blockade all the windows.
It takes radioactive materials two weeks to decay, so stock up on two weeks' worth of food and water.
But if you are outside and know the blast is coming, you might have time to get to a better shelter, but first you should get on the ground with your hands behind your head and brace yourself.
Never look at the blast, because it can cause you to go blind temporarily.
