Doomsday Clock: Humanity Still 100 Seconds from Midnight
The Doomsday Clock remains at its direst setting amid nuclear and climate threats, warning that global catastrophe is perilously close without urgent action.
The Doomsday Clock, a globally recognized symbol of existential risk, remains set at 100 seconds to midnight, conveying an urgent message: humanity stands perilously close to self-annihilation. This symbolic clock, managed since 1947 by the Bulletin of the Atomic Scientists, is a measure of how near we are—as a species—to a global catastrophe driven by our own actions.
In recent years, a convergence of dangers—nuclear tensions, unchecked climate change, the rise of disinformation, and the emergence of destabilizing technologies—has prompted the scientists to keep the clock at its closest-ever position to midnight. As political will fails to match the scale of these challenges, the clock’s dire setting serves as a stark call to action for policymakers, scientists, and citizens alike.
Understanding the Doomsday Clock
Since its debut on the cover of the Bulletin in 1947, the Doomsday Clock has been a barometer of global risk related to nuclear weapons, climate change, and emerging technological threats. Every January, the Bulletin’s Science and Security Board evaluates world events and determines whether to move the clock’s hands closer to, or farther from, midnight—the metaphorical hour of irreversible catastrophe.
- Midnight represents the onset of global disaster—be it nuclear war, environmental collapse, or catastrophic misuse of technology.
- Movement toward midnight indicates rising risk and an unstable international environment.
- Movement away from midnight reflects effective risk mitigation and multilateral cooperation.
The clock has long captured public imagination, acting as both a warning and a call to action as the world navigates an ever-evolving threat landscape.
Why Remain at 100 Seconds to Midnight?
In the most recent resetting, the Bulletin of the Atomic Scientists decided to keep the clock at 100 seconds to midnight—the closest the clock has ever been to global catastrophe. The decision was not made lightly. Instead, it stemmed from a sobering analysis of interlinked risks that, if left unchecked, could spell disaster for civilization.
Above all, the Board cited two existential threats:
- Nuclear weapons proliferation and instability.
- Inadequate response to accelerating climate change.
Each of these dangers has grown more acute, compounded further by the disruptive force of emerging technologies and a breakdown in reliable information systems worldwide.
Nuclear Risk: Age-Old Threats Renewed
Nuclear weapons, and the unstable geopolitical relationships governing their use, remain at the heart of the Doomsday Clock’s setting. Recent years have witnessed:
- Escalating tension between nuclear-armed states, including the United States, Russia, China, and regional actors like North Korea and Iran.
- Disintegration of long-standing arms control agreements, such as the Intermediate-Range Nuclear Forces Treaty, increasing the risk of inadvertent conflict or miscalculation.
- The rise of new technologies that could destabilize deterrence, such as hypersonic missiles and space-based weaponry.
- Lack of progress—or actual regression—in nuclear disarmament efforts.
What others are reading
These dynamics create a volatile global environment where misunderstandings or even technical failures could spark catastrophic conflict. As former California Governor Jerry Brown, executive chair of the Bulletin’s board, implored: “Wake up, America! Wake up, world! We have to do more … We can still pull back from the brink.”
Climate Change: An Escalating Global Crisis
While nuclear weapons pose an immediate existential threat, climate change is a slow-moving, but relentless, crisis that compounds global instability. The Bulletin’s decision to hold the clock at 100 seconds to midnight was heavily influenced by:
- Continuing increases in greenhouse gas emissions despite scientific warnings and international agreements.
- Escalating extreme weather events, from wildfires to floods, hurricanes, and devastating droughts.
- Political inertia and even reversal of progress, with major nations insufficiently honoring climate accords or withdrawing altogether.
- Insufficient investments in renewable energy, adaptation strategies, and climate resilience measures.
Climate change does not only threaten planetary habitability, but also acts as a force multiplier for conflict, migration, resource shortages, and economic instability.
Emerging Threats: Technology, Misinformation, and the Weaponization of Space
Beyond the familiar specters of nuclear war and environmental collapse, the modern era introduces an array of new dangers that increase humanity’s peril.
Disinformation and Information Warfare
The deliberate spread of disinformation has become a core concern for the Science and Security Board. In an age of social media and digitally networked societies, the dissemination of fake news and propaganda can:
- Sow chaos and mistrust among populations.
- Undermine democratic institutions and science-based policymaking.
- Stir conflict between nations, eroding diplomatic solutions to global problems.
This “infodemic” limits society’s ability to respond rationally and collectively to existential threats.
Unregulated Technological Advances
Advances in science and engineering hold the promise of great benefit—but also pose significant risks when unregulated or poorly understood. Current areas of particular concern include:
- Gene editing: Breakthroughs like CRISPR offer hope in medicine and agriculture but raise fears about unintended consequences, ethics, and bioweaponization.
- Autonomous weapons: AI-controlled systems lower the threshold for conflict and may act unpredictably in high-stress scenarios.
- Cyber-attacks: Increasing reliance on digital infrastructure exposes societies to catastrophic failures and manipulation.
Without meaningful oversight and global governance, these technologies could introduce risks on par with those of nuclear arms.
The New Arms Race: Weaponizing Space
The Bulletin’s experts highlight the dangerous trend of militarizing outer space—a new arena for great-power rivalry:
- Development and testing of antisatellite weapons by the United States, Russia, China, and India threaten to spark a space arms race.
- The destruction of satellites could cripple communications, navigation, and early warning systems vital to modern life and global stability.
As retired Air Force General Robert Latiff observed, these developments increase the chances for miscalculation and catastrophic escalation in an increasingly complex security environment.
The Role of Political Will: Stalled Progress and Missed Opportunities
Ultimately, the dire setting of the clock reflects the world’s ongoing failure to adequately address these mounting dangers. The Board notes several critical points:
- International treaties and multilateral frameworks have weakened or collapsed, from nuclear arms agreements to climate compacts.
- Global leadership has remained paralyzed by division, nationalism, and short-term thinking.
- Progress on risk reduction, whether through diplomacy, scientific collaboration, or public mobilization, has been insufficient to meaningfully move the world farther from disaster.
Yet, as the scientists emphasize, it is not too late to act. The clock’s proximity to midnight is not a foregone conclusion—it is a summons to collective responsibility and renewed action.
What Can Be Done? Steps Back from the Brink
Despite the grim prognosis, the Bulletin maintains hope that humanity can pull back from the brink. The following steps are repeatedly emphasized:
- Revitalize arms control: Renew and expand nuclear agreements, promote disarmament, and invest in diplomatic engagement among nuclear powers.
- Accelerate climate action: Aggressively reduce emissions, rejoin or strengthen climate treaties, invest in adaptation, and speed clean energy innovation.
- Strengthen global governance: Build institutions to manage emerging technology risks, promote international norms, and prepare robust regulatory frameworks.
- Combat disinformation: Safeguard the integrity of science, defend information ecosystems, and promote responsible civic engagement.
- Promote science-based policy: Anchor national and international decisions in transparent, peer-reviewed science and the best available evidence.
- Engage the global public: Educate and inspire action at all levels of society, urging every individual to be an agent of positive change.
The Doomsday Clock thus serves not only as a warning, but as a blueprint for resilience, adaptation, and hope—provided there is political courage and public willingness to act.
