Doomsday Clock moves to 85 seconds to midnight due to nuclear and climate threats

Summarized by NextFin AI
  • The Doomsday Clock has been moved forward to 85 seconds to midnight, the closest it has ever been, highlighting a world on the brink of multiple existential crises.
  • The expiration of the New START Treaty and the rise of AI in military systems are primary drivers for this advancement, indicating a potential return to an unconstrained nuclear arms race.
  • The spread of generative AI and deepfake technology has eroded trust in the information ecosystem, complicating international diplomacy on critical issues like climate change.
  • The movement of the clock signals systemic risk in global markets, with increased defense spending overshadowing green energy transitions, amidst climate instability and resource scarcity.

NextFin News - In a stark warning to global leaders and the public, the Bulletin of the Atomic Scientists announced on Tuesday, January 27, 2026, that the hands of the Doomsday Clock have been moved forward to 85 seconds to midnight. This adjustment marks the closest the symbolic clock has ever been to a theoretical global apocalypse, surpassing the previous record of 89 seconds set just one year ago. The decision, finalized by the Bulletin’s Science and Security Board in consultation with its Board of Sponsors—which includes eight Nobel laureates—was unveiled at the Keller Center in Chicago, home to the University of Chicago Harris School of Public Policy.

The 2026 update highlights a world teetering on the edge of multiple existential crises. According to the Bulletin of the Atomic Scientists, the primary drivers for this four-second advancement include the imminent expiration of the New START Treaty between the United States and Russia, the rapid integration of artificial intelligence into military systems, and the continued failure of nations to meet climate change mitigation targets. Alexandra Bell, President and CEO of the Bulletin, stated during the announcement that "every second counts and our time is running out," emphasizing that the current geopolitical climate is more precarious than even the height of the Cold War.

The most immediate threat cited by the board is the collapse of the nuclear arms control framework. The New START Treaty, the last remaining agreement limiting the nuclear arsenals of the world’s two largest nuclear powers, is set to expire on February 5, 2026. With no replacement in sight and diplomatic channels increasingly strained, experts warn of a return to an unconstrained nuclear arms race. Daniel Holz, a professor at the University of Chicago and chair of the Science and Security Board, noted that for the first time in over half a century, there will be no legal barriers preventing a massive expansion of nuclear stockpiles. This vacuum is exacerbated by the "neo-imperialist" rhetoric and aggressive posturing observed in Russia, China, and the United States, where nationalistic interests are increasingly prioritized over collective security.

Beyond traditional warfare, the rise of "information Armageddon" has become a critical factor in the clock’s movement. The uncontrolled spread of generative AI and deepfake technology has eroded the global information ecosystem, making it difficult for populations to distinguish fact from fiction. Nobel Peace Prize laureate Maria Ressa highlighted that this predatory technology profits from division and spreads lies faster than truth, fundamentally undermining the trust required for international diplomacy. When facts are no longer a shared reality, the ability of states to negotiate on climate change or nuclear non-proliferation is severely compromised.

From a financial and economic perspective, the movement of the Doomsday Clock serves as a high-level indicator of systemic risk. The militarization of space and the pursuit of costly missile defense systems, such as the proposed "Golden Dome" project, signal a shift in global capital toward defense spending at the expense of green energy transitions and social infrastructure. Data from recent climate reports suggest that despite record-breaking heatwaves and floods in 2025, global carbon emissions have not yet reached the downward trajectory required to avoid the most catastrophic effects of warming. The intersection of climate instability and resource scarcity is expected to further fuel regional conflicts, creating a feedback loop of instability that threatens global market resilience.

Looking forward, the trend suggests a world moving toward a "winner-takes-all" great power competition. The fragmentation of global trade and the rise of protectionist tariffs are likely to complicate the international cooperation needed to regulate emerging technologies like AI. If the New START Treaty is allowed to lapse without a framework for future dialogue, the probability of a miscalculation leading to nuclear escalation will reach unprecedented levels. However, the Bulletin maintains that the clock is a call to action rather than a prophecy of doom. Reversing the hands will require a fundamental shift back toward multilateralism, the renewal of arms control transparency, and a global commitment to regulating the digital frontier before it further destabilizes human governance.
