The Doomsday Clock was started in 1947 by the Bulletin of Atomic Scientists at the University of Chicago. The clock represents how far humanity is from destroying itself with midnight representing destruction. It was originally developed during the nuclear threat and minutes have been added and taken away based on political factors throughout the world. Environment and technology along with nuclear threats are now factored into movement of the clock. On 1/17/07 the clock was moved from seven minutes to five minutes. Who do we have to thank for the time change- the usual suspects the U.S., Russia, Iran and North Korea as well as any number of terrorist groups trying to get their hands on a bomb. We also have climate change to thank. Robots do not pose a great threat to humanity…yet.
