'Doomsday Clock' moves closer to midnight amid threats of climate change, nuclear war, pandemics, AI

A science-oriented advocacy group says the Earth is moving closer to destruction. The Bulletin of the Atomic Scientists said Tuesday that they've moved their “Doomsday Clock” to 89 seconds to midnight, the closest it has ever been, because of worsening threats ranging from nuclear war to climate change to pandemics and artificial intelligence. The clock had stood at 90 seconds to midnight for the past two years. The advocacy group began to use a clock in 1947 to symbolize the potential and likelihood of people doing something to end humanity.
