The Doomsday Clock symbolises how close humanity is to global catastrophe, providing a visual representation of existential risk. Managed by the Bulletin of the Atomic Scientists, this clock reflects threats from nuclear weapons, climate change, and emerging technologies. The closer the clock is to midnight, the greater the perceived danger to global safety.

Doomsday Clock

Updated annually, its time is set by a team of scientists and experts who evaluate worldwide events and trends. First introduced in 1947, the clock has since become a recognised measure of global security concerns. By highlighting critical issues, it aims to encourage action and awareness about the challenges facing humanity and the planet.

Understanding its significance offers valuable insight into modern global risks.

What Is the Doomsday Clock

Today, the Doomsday Clock is a powerful symbol set up in 1947, highlighting the peril of truly existential global disasters. This clock was first created during the nuclear face-off between the US and the USSR, emphasizing the role of nuclear danger in shaping our world. The Bulletin of the Atomic Scientists, an organization of dedicated researchers and experts, is responsible for this symbolic countdown.

It draws on the metaphor of “minutes to midnight” to describe how close humanity is to annihilation. Midnight symbolizes a hypothetical moment of total global destruction. The clock’s position is moved each year in late January, based on the most pressing global risks at the time. Since its establishment, it has made 26 changes.

These alterations are a direct result of changes in geopolitics, emerging technologies, and environmental concerns. The clock was moved to its closest time of 89 seconds to midnight in January 2023. This troubling development is a testament to the increasing dangers of nuclear proliferation and the climate crisis.

In 1953, 2018, and 2020, we were as little as 2 minutes to midnight. The combined threats of thermonuclear weapon testing and rapid, dangerous climate change moved us back to the brink. The most distant position ever was 17 minutes to midnight in 1991. This was all happening in the wake of the end of the Cold War and the signing of various arms reduction treaties.

The breaking of the Berlin Wall had a tremendous impact on the subsequent changes in the clock's time. Moreover, nuclear developments in India and Pakistan have significantly coloured and influenced these shifts. Though widely misinterpreted, the Doomsday Clock is not a prediction - it serves as an unmistakable warning.

Now, more than ever, the clock serves as an urgent reminder that we need to work together internationally to overcome these existential threats. Its cultural impact extends to music, with doomsday clock references like Iron Maiden’s “2 Minutes to Midnight.

Origins of the Doomsday Clock

The Doomsday Clock was first set in 1947. In 1949, Hyman Goldsmith, co-founder of the Bulletin of the Atomic Scientists, invited artist Martyl Langsdorf to create the cover art for the June edition. Langsdorf created a very basic clock face with its hands showing 7 minutes until midnight. That powerful imagery helped convey what I think was the very real, tangible threat of nuclear danger in the early Cold War years.

This was more than just artwork; it was an evocative image that illustrated humanity’s narrow escape from self-annihilation, shaped by the political and technological landscape of the time. During its initial years, the Clock emphasized a growing threat from nuclear weapons as the major concern, reflecting the insights of leading physicists.

On 26th November 1991, this radical editorial made waves. It was a brave announcement that the East-West nuclear arms race was over, ending 40 years of tension. That same year, the Clock was adjusted to 17 minutes to midnight. This was the most time away from global catastrophe it had ever been.

The optimism of the era radiated from those words. Soundbites such as “[t]he myth of monolithic communism has been shattered” succinctly summed up a world transformed by the end of the Cold War. Over the years, the Clock’s focus expanded to include the rising threats of climate change and dangerous technologies.

By 2019, it was business as usual. This standstill brought into sharper focus the multiplying dangers of nuclear weapons, climate change, and the increasing peril of the information age. These issues were identified as mutually exacerbating, compounding risks and perilously endangering global stability.

By 2023, the Clock stood at a worrisome 2 minutes to midnight. This moment was a stark reminder of ongoing nuclear rivalries and other growing dangers. The Bulletin’s deepening alarm stemmed from a deteriorating world picture in the social and natural sciences, highlighting the urgent need for international dialogue and disarmament initiatives.

How the Doomsday Clock Works

The Doomsday Clock is a visual, metaphorical, symbolic tool meant to illustrate by how far humanity is from a global catastrophe. Their science and security board enforces it. This board features some of the foremost authorities in the fields of nuclear science, climate science and global security.

The clock is not a scientific tool, but rather a symbolic measure of humanity’s distance to existential threats. Since its establishment in 1947, it has been moved 25 times to account for increasing and decreasing peril around the globe. At first, the acute focus was on nuclear weapons, which created an unparalleled threat in the wake of World War II.

In the intervening decades, the scope has broadened to address the deepening threat of climate change, biological hazards, and geopolitical instability. The clock’s changes are measured in seconds, highlighting the severity and immediacy of the threats at hand.

For example, in January 2023, it was moved to 90 seconds to midnight—the closest it has ever been. In comparison, the furthest setting was 17 minutes in 1991, a sign of hope following the conclusion of the Cold War. These adjustments are not forecasts, but rather a call to action, designed to spur immediate and decisive action by world leaders and policymakers.

The decisions are made on a 90% consensus basis amongst the board, highlighting their collaborative and diligent decision making process. More than just a metaphor, the clock represents the Bulletin’s long-standing fear that humanity is on the brink of extinction.

Second, it focuses on the erosion of global norms and institutions that might stave off disaster. By highlighting urgent matters such as climate change policies and nuclear disarmament, the clock calls for an international reaction to these threats. It is meant to encourage public understanding and action to reduce the threat of nuclear war and conflict.

Key Events Influencing the Clock

The Doomsday Clock illustrates the complex ways in which various issues affect our overall global security. Its place moves up or down depending on the tectonic geopolitical and technological plate movements. Perhaps the most important influence has been the pressure on U.S.-Russia relations.

Combined, these four nations possess nearly 90 percent of the world’s nuclear weapons. Deteriorating diplomacy like the 2019 collapse of the Intermediate Nuclear Forces Treaty exacerbates the situation. This treaty was one of the cornerstones of Cold War stability, placing limits on these destabilizing medium-range missiles.

It’s hard to overstate what its dissolution means for arms control efforts. Since its creation in 1947, the Bulletin of the Atomic Scientists has adjusted the clock 26 times, a process guided by their evaluation of existential threats. In 1990, the clock was set to two and a half minutes to midnight, representing a period of relative safety following the end of the Cold War.

The situation has worsened over time. By 2023, the clock was moved to 89 seconds to midnight, the closest humanity has come to potential catastrophe in its history. This reflects growing concerns not only about nuclear risks but about emerging challenges like climate change and disruptive technologies.

The COVID-19 pandemic, which presented an ideal moment to galvanize international action towards improved preparedness, instead exposed the frailty of global collaboration. Such crises serve as a stark reminder of how today’s threats are more connected than ever before. The clock is still a powerful symbol, a call to action for all of us to work together to reduce these risks.

Implications of Reaching Midnight

The Doomsday Clock serves as a metaphorical measure of how close the human race is to wiping itself out. By setting its metaphorical clock at 100 seconds to midnight, it conveys an all-time-high level of concern regarding global security. This position was created in January of 2020, reflecting the urgent need for action from international agencies and leaders alike.

The Clock addresses pressing global issues, including climate change and the accelerating development of increasingly powerful and dangerous technologies. These technologies, such as synthetic biology and artificial intelligence, pose a nuclear threat that could lead to catastrophic disruptions. The Bulletin’s Science and Security Board has issued a clarion tone of urgency about these existential threats, emphasizing the prime responsibility of political leaders to base their decisions on solid scientific evidence and factual analysis.

Historically, the Clock’s location has changed to symbolize the state of international security. In 1991, the Doomsday Clock made its most significant shift from midnight, advancing 17 minutes after the Cold War ended and the Strategic Arms Reduction Treaty was signed. This represented a major step forward in the international disarmament movement.

Today's proximity to midnight underscores the world’s leaders' inability or unwillingness to adequately address the nuclear risk and climate change challenges on the horizon. The Bulletin has long warned that failure to act on nuclear proliferation could lead to catastrophic destruction for humanity.

Critics, such as Keith Payne, argue that the Clock may overstate the impact of certain developments, like arms control treaties, on global security. Yet, advocates like Lawrence Krauss continue to highlight its importance, insisting that its warnings must inform action to protect future generations.

Perhaps most strikingly, the average age of the Bulletin’s membership is under 35, highlighting the increasing concern among younger generations regarding the possibility of reaching midnight and the associated consequences for civilization.

Location and Visibility of the Clock

The Doomsday Clock has thus evolved from a tangible object into a symbol that is deeply entrenched in contemporary culture. This iconic Clock made its original debut in the Bulletin of the Atomic Scientists back in 1947, where it represented the urgent need for international dialogue on nuclear risk. Today, it is prominently displayed on the Bulletin’s website as part of its logo. The Bulletin ceased printing its paper edition in 2009, but the Clock's legacy continues.

Since then, the Clock has established itself as a potent digital symbol of the world’s continuing global risks, particularly the nuclear danger posed by major powers. Its strong online presence makes it easily accessible and attractive to many people, underscoring its value as an advocacy tool for building awareness about catastrophic disruptions.

Each year, the Clock’s position is recalibrated, with public announcements typically occurring in late January. This event marks a historic moment, shining a spotlight on urgent global challenges. In January 2025, it was moved to 89 seconds to midnight — the closest it has ever been, highlighting the extreme danger we face from current affairs related to nuclear arsenals.

The maximum time from midnight was 17 minutes in 1991, a testament to hope following the end of the Cold War. These amendments are a testament to how quickly the global threat landscape changes. Our nuclear risks and climate change are more real than ever and are mainstays.

Cultural references continue to increase its prominence. The Clock is central to the plot of Alan Moore and Dave Gibbons’s graphic novel, Watchmen. It represents humanity’s fragile existence in a disordered universe.

In a 2017 episode of Doctor Who titled “The Pyramid at the End of the World,” the Monks dramatically changed all the clocks to three minutes before midnight. This bold move underscored the episode’s lasting cultural influence. Together, these examples illustrate how the Clock transcends its scientific origins to become a compelling metaphor for the challenges humanity faces in the nuclear age.

Significance of the Doomsday Clock Today

Today, the Doomsday Clock stands as a striking reminder of humanity’s shared obligation to confront existential global challenges. Now at 89 seconds to midnight, it represents the nearest approach to disaster — in all its forms — since the clock’s establishment in 1947. This change underscores the deteriorating nuclear landscape, exacerbated by rising political tensions and emerging technologies, particularly the nuclear threat posed by nations like North Korea.

In late 2022, Russian President Vladimir Putin upped the ante—a new nuclear doctrine raised the threshold for a nuclear strike. This decision sent a clear and deeply alarming message to the international community. Such developments make painfully clear the need for continual vigilance and cooperation among world leaders, echoing the sentiments of many physicists and scientists who advocate for disarmament.

The clock, which is kept by the Bulletin of the Atomic Scientists, is a deeply symbolic and well-known marker of global fragility. It has only been reset 26 times since its introduction. Each change marks a step into the more dangerous reality the world has presented us, reflecting the potential for catastrophic disruptions if we fail to act.

Its aim isn’t just to calculate risk -  it’s to motivate change. The clock’s proximity to midnight is intended as a call to action, urging nations to prioritise diplomacy, reduce nuclear stockpiles, and address other existential threats. The midnight metaphor as global catastrophe underscores the need for all of us to take dramatic action, now, toward building a safer, more secure world.

There is no doubt that the Doomsday Clock has a global impact that reaches far beyond its American origins. Indeed, more than 50 percent of the Bulletin’s online readership comes from outside the United States. This shows its global relevance, bringing people from all different communities together around recognizing this threat that we all share, especially in light of current affairs.

The clock serves as a warning about the perils of rapid, unregulated technological change and the escalation of geopolitical tension. It’s meant to be a stark warning, but a call to action for all nations to address the nuclear danger and work collaboratively to avert disaster.

Conclusion

The Doomsday Clock, like the dystopia it foretells, is a heavy, but necessary, reminder of the choices facing humanity. It is not a measure of time but a reflection of the dangers we are imposing on the public and the need to fix those dangers. From climate change to today’s nuclear threats, the clock serves as a reminder that we all share the responsibility. Its hands inch toward midnight every time we overlook available solutions and stray from the path of collaboration.

This symbol is a call to understand, act, and change. It urges each person, leader, and community to embrace science, diplomacy, and innovation. Every small step can add up to great change when we come together.

Get the latest info, spread the word, and help us fight for a better future. The clock’s message is simple: the future isn’t set. What we do today determines what we’ll see tomorrow.
