The clock's current setting.

The Doomsday Clock is a device maintained by the Bulletin of the Atomic Scientists at the University of Chicago which is used to indicate the threat of a nuclear, biological, or environmental disaster. It is a clock face, where midnight represents a nuclear war or an environmental catastrophe, and noon represents world peace. It has been "operational" since 1947 when it first appeared on the cover of the Bulletin, where it has appeared ever since. It has changed 24 times since 1947, moving forwards 16 times whilst moving backwards 8 times. The lowest time it reached was 11:43, following the Soviet Union's collapse. It was previously closest to midnight during 1953, after the US and the USSR tested their thermonuclear weapons, where it read 11:58.[1]


Graph of the changes to the Doomsday Clock time since 1947. Note: The lower the graph becomes, the higher the probability of catastrophe is deemed to be.

In recent times, the clock has been changing for the worse, albeit slowly. On January 22, 2015, it was set "3 minutes to midnight", due to "unchecked climate change, global nuclear weapons modernizations, and outsized nuclear weapons arsenals", and the failure of "international leaders" to do anything about it.[2] In January 2017, it was set "2.5 minutes to midnight", due to Donald Trump.[3] The clock changed in January 2018, when it was again set "2 minutes to midnight" — a level unseen since 1953 — mostly due to Donald Trump once more.[4] The Bulletin of the Atomic Scientists said it saw an increase in dangers to humanity, from climate change to nuclear warfare.[5] On January 23rd, 2020, the clock was set 100 seconds to midnight, the closest the clock had ever been to midnight.[6] The clock's time was reaffirmed on January 27th, 2021, consequently the clock is still 100 seconds to midnight.[7]

The worst part regarding all of this is that nobody seems to acknowledge nor care about these solemn warnings.

A different kind of clock, counting towards a different kind of doom
It would be a stronger world, a stronger loving world, to die in.
