What's the Point of a Doomsday Clock?

Imagine a giant clock that counts down to the end of the world. That's what the Doomsday Clock is, like a warning sign for our planet. It helps scientists and leaders know if we're getting closer or farther from a big disaster, like nuclear war or climate change. The clock ticks forward when things get worse and moves backward when they get better.
