The Doomsday Clock Is Now 85 Seconds to Midnight. Here’s What That Means

In a sobering announcement that has sent shockwaves across the global scientific and political landscape, the Doomsday Clock has been advanced to 85 seconds before midnight—marking the closest humanity has ever stood to the symbolic brink of global catastrophe. This grim milestone was revealed by the Bulletin of the Atomic Scientists’ Science and Security Board (SABS), the esteemed group of experts entrusted with the annual adjustment of the clock’s hands. Their decision reflects a convergence of escalating existential threats: the persistent specter of nuclear warfare, the unchecked rise of artificial intelligence, the intensifying climate crisis, and the resurgence of biosecurity risks—all compounded by the erosion of international cooperation and the rise of nationalistic autocracies.

The Doomsday Clock, conceived in 1947 during the height of the Cold War, has long served as a metaphorical barometer of humanity’s proximity to self-inflicted annihilation. Midnight on the clock represents the moment when the Earth becomes uninhabitable, a fate that now looms nearer than ever. Last year, the clock was set to 89 seconds to midnight, a stark warning that progress in addressing global challenges—ranging from nuclear risk and climate change to disruptive technologies and disinformation—was insufficient. “Every second of delay in reversing course,” the SABS warned, “increases the likelihood of a global disaster.”

Yet, rather than heeding this clarion call, the world’s major powers have doubled down on aggressive and nationalist agendas. The United States, Russia, China, and others have deepened their rivalries, undermining the very international trust and cooperation needed to mitigate existential risks. “The dangerous trends in nuclear risk, climate change, disruptive technologies like AI, and biosecurity are accompanied by another frightening development: the rise of nationalistic autocracies in countries around the world,” said SABS president Daniel Holz. “Our greatest challenges require international trust and cooperation, and a world splintering into ‘us versus them’ will leave all of humanity more vulnerable.”

The SABS report paints a bleak picture of a world where hard-won global understandings are unraveling, accelerating a winner-takes-all great power competition. This fragmentation is eroding the international cooperation essential to reducing the risks of nuclear war, climate change, the misuse of biotechnology, and the potential threat of artificial intelligence. “Far too many leaders have grown complacent and indifferent, in many cases adopting rhetoric and policies that accelerate rather than mitigate these existential risks,” the organization stated.

Despite the dire prognosis, the Doomsday Clock also serves as a reminder that there is still time to act. The SABS outlined several pathways to pull humanity back from the brink. The United States and Russia, for instance, could resume talks to limit their nuclear arsenals, while multilateral agreements and national regulations could curb the potential misuse of artificial intelligence in creating biological threats. The U.S. Congress could incentivize and invest in rapid reductions in fossil fuel use, while the United States, Russia, and China could initiate dialogues to establish guidelines for integrating AI into their militaries, particularly in nuclear command and control systems.

“National leaders, particularly those of the United States, Russia, and China, must take the lead in finding a way out of the abyss,” the experts concluded. “Citizens must insist that they do so.” This call to action underscores the urgency of the moment: the clock is ticking, and the world stands at a crossroads. The choices made in the coming years will determine whether humanity can avert catastrophe or hurtle toward the midnight hour.
