So, let's hear more about this story.
Famous group of experts have warned that the world is the closest it has ever been to disaster.
They've set the doomsday clock at 85 seconds to midnight.
The doomsday clock was developed by an organisation called the Bulletin
of Atomic Scientists to warn about dangerous technologies and risks in the world.
Doomsday means the end of the world or a time when something very bad will happen.
The idea is that the closer the Doomsday Clock is to midnight, the closer humanity is to being destroyed.
The Doomsday Clock was set up in 1947 as a way to track the risk of nuclear war.
Scientists now consider other threats like climate change and artificial intelligence and update the clock every year.
Scientists move the clock forward four seconds on Tuesday, indicating that the risk of disaster is getting worse.
Let's have our first headline from The Independent, a British news website.
