fraction in the Clock's history, Lawrence Krauss, one of the scientists from the Bulletin, warned that political leaders must make decisions based on facts, and those facts "must be taken into account if the future of humanity is to be preserved." In an announcement from the Bulletin about the status of the Clock, they went as far to call for action from "wise" public officials and "wise" citizens to make an attempt to steer human life away from catastrophe while humans still can. On January 24, 2018, scientists moved the clock to two minutes to midnight, based on threats greatest in the nuclear realm. The scientists said, of recent moves by North Korea under Kim Jong-un and the administration of Donald Trump in the U.S.: "Hyperbolic rhetoric and provocative actions by both sides have increased the possibility of nuclear war by accident or miscalculation". The clock was left unchanged in 2019 due to the twin threats of nuclear weapons and climate change, and the problem of those threats being "exacerbated this past year by the increased use of information warfare to undermine democracy around the world, amplifying risk from these and other threats and putting the future of civilization in extraordinary danger." On January 23, 2020, the Clock was moved to 100 seconds (1 minute, 40 seconds) before midnight. The Bulletins executive chairman, Jerry Brown, said "the dangerous rivalry and hostility among the superpowers increases the likelihood of nuclear blunder... Climate change just compounds the crisis". The "100 seconds to midnight" setting remained unchanged in 2021 and 2022. On January 24, 2023, the Clock was moved to 90 seconds (1 minute, 30 seconds) before midnight, meaning that the Clock's current setting is the closest it has ever been to midnight since its inception in 1947. This adjustment was largely attributed to the risk of nuclear escalation that arose from the 2022 Russian invasion of Ukraine. Other reasons that were cited included climate change, biological threats such as COVID-19, and risks associated with disinformation and disruptive technologies. Reception The Doomsday Clock has become a universally recognized metaphor according to The Two-Way, an NPR blog. According to the Bulletin, the Clock attracts more daily visitors to the Bulletin's site than any other feature. Anders Sandberg of the Future of Humanity Institute has stated that the "grab bag of threats" currently mixed together by the Clock can induce paralysis. People may be more
