I've never paid much attention to the Doomsday clock, but they're saying its been reset to the closest time its ever been to midnight. Apparently, when it hits midnight, it's total world obliteration. As it stands, the Doomsday clock is 90 seconds to midnight!
The Doomsday clock has been moved in hopes that the world will unite and take action with the many concerns plaguing the planet right now.
