How close are we to the end of the world? Check the Doomsday Clock
The Doomsday Clock has been a symbol of global tension since 1947. The Bulletin of the Atomic Scientists monitors nuclear proliferation and climate change, adjusting the time to midnight to reflect how close we are to the end of the world. Since its introduction, the clock has been adjusted 22 times and it currently sits at two and a half minutes to midnight.
