Recent events that have brought the Doomsday Clock into the news include escalating tensions between nuclear-armed nations, the continued impact of climate change, and the rapid advancement of disruptive technologies such as artificial intelligence and cyber warfare. These factors have contributed to the ongoing existential risks to humanity, prompting the Bulletin of the Atomic Scientists to maintain the Doomsday Clock at 90 seconds to midnight for the second consecutive year.
The Doomsday Clock, created in 1947, is a symbolic representation of the likelihood of a man-made global catastrophe. It is maintained by the members of the Bulletin of the Atomic Scientists and serves as a metaphor for the threats posed by unchecked scientific and technological development. The Clock's minute hand, which moves closer to or further from midnight, signifies the perceived level of danger to humanity. The decision to adjust the position of the Doomsday Clock is made annually by the Bulletin's Science and Security Board in consultation with its Board of Sponsors, which includes 13 Nobel laureates.
