The Bulletin of the Atomic Scientists announced on January 28 that the Doomsday Clock has been set to 89 seconds to midnight, marking its closest approach to symbolic apocalypse. This adjustment reflects concerns over insufficient progress in addressing existential risks threatening humanity.
Daniel Holz, a professor at the University of Chicago and chair of the Science and Security Board of the Bulletin, stated, “The world has not made sufficient progress on existential risks threatening all of humanity. In setting the clock closer to midnight, we send a stark signal.” He further emphasized, “Every second of delay in reversing course increases the probability of global disaster.”
For 75 years, the Bulletin has used this metaphorical clock to signify how close humankind is to potential catastrophe. The hands have shifted based on actions taken—or not taken—regarding threats such as climate change and nuclear conflict. The last adjustment occurred in 2023 when it was set at a minute and a half to midnight.
Holz warned during a news conference, “Because the world is already perilously close to the precipice, any move towards midnight should be taken as an indication of extreme danger and an unmistakable warning.”
The Bulletin was established by Manhattan Project scientists after World War II. Its iconic Doomsday Clock was created in 1947 by artist Martyl Langsdorf. Today, it resides at the Keller Center within the University of Chicago’s Harris School of Public Policy.
This year's decision cites several factors: inadequate responses to climate change impacts; global nuclear arms movements; increased use of generative AI for disinformation and military purposes; and lack of preparedness for emerging pathogens. Additionally mentioned was U.S. President Trump's withdrawal from international climate and health agreements.
Despite these warnings, Juan Manuel Santos, chair of The Council of Elders and former president of Colombia, reassured that action can still be taken: “There is still time to make the right choices to turn back the hands of the Doomsday Clock.” He added an urging reminder from his country: “‘Cada segunda cuenta’—every second counts. Let us use each one wisely.”
