The Doomsday Clock isn't "accurate" in a precise, predictive sense; it's a symbolic metaphor by the Bulletin of the Atomic Scientists to warn about existential threats like nuclear war and climate change, acting more like a "diagnosis" of global risks than a crystal ball, with its setting based on expert judgment rather than a scientific formula. While some call it alarmist or political, its value lies in sparking crucial public dialogue and policy discussions on dangerous technologies and global threats, according to its operators.
While the clock being close to midnight might make it seem that the world is headed toward a global catastrophe, this result isn't considered inevitable. The Doomsday Clock is not a typical clock because it can also move backward, so there is still time to change the countdown to midnight.
It is now 89 seconds to midnight.
When the Doomsday Clock hits midnight, it symbolizes humanity reaching the point of "global catastrophe," meaning civilization as we know it ends due to self-inflicted threats like nuclear war, climate collapse, or disruptive technologies, though it's a metaphor, not a prediction, meant to spur action by showing we've crossed a critical threshold. It signifies a point of no return where the lights go out and we've essentially destroyed the world with our own dangerous tech, according to the Bulletin of the Atomic Scientists.
In short: The Bulletin of the Atomic Scientists moved the symbolic Doomsday Clock to 89 seconds before midnight, the closest in its history, citing unchecked nuclear modernization, worsening climate inaction, and the rise of AI and disinformation.
The Doomsday Clock is set once a year by the Bulletin of the Atomic Scientists.
The clock calculates the aging of blood and other tissues by tracking methylation, a natural process that chemically alters DNA over time. By comparing chronological age to the blood's biological age, the scientists used the clock to predict each person's life expectancy.
Clocks may have to skip a second — called a "negative leap second" — around 2029, a study in the journal Nature said Wednesday. "This is an unprecedented situation and a big deal," said study lead author Duncan Agnew, a geophysicist at the Scripps Institution of Oceanography at the University of California, San Diego.
Until recently, the closest it had ever been set was at two minutes to midnight—first in 1953, when the U.S. and Soviet Union both tested thermonuclear weapons, and then in 2018, citing “a breakdown in the international order” of nuclear actors, as well as the continuing lack of action on climate change.
He stated that it is inconsistent and not based on any objective indicators of security, using as an example its being farther from midnight in 1962 during the Cuban Missile Crisis than in the "far calmer 2007".
The Cuban Missile Crisis of October 1962 was a direct and dangerous confrontation between the United States and the Soviet Union during the Cold War and was the moment when the two superpowers came closest to nuclear conflict.
89 Seconds to Midnight: Doomsday Clock Time Set for 2025 January 28, 2025. Announced today, the Bulletin of the Atomic Scientists' Doomsday Clock has been set to 89 seconds to midnight.
It basically is an app where you feed in all your health information, personal information, social information — any fact about you — and it promises to tell you your death date." Ethicist Art Caplan discusses the potential accuracy of a death clock app and the need for related health counseling.
DC counts it as one, so yes. DC Crises Events usually contain something that, going forward, will alter the DC Universe from then on. Doomsday Clock fits this as Manhattan undoes the damage he initially did by moving Alan Scott's Lantern back into reach.
The Bulletin of Atomic Scientists maintains a metaphorical clock, called The Doomsday Clock, but it doesn't tell time. The placement of the minute hand on the clock instead represents how close humanity is to self-inflicted destruction from unchecked advances in science and technology.
The threat levels — and threats themselves — have evolved
The Bulletin has repositioned the clock hands 26 times since 1947. It first moved — from seven to three minutes before midnight — in 1949, after the Soviet Union successfully tested its first atomic bomb.
When the Doomsday Clock strikes midnight, that's it. The lights are out, and no one is coming to turn them back on. “When the clock is at midnight, that means there's been some sort of nuclear exchange or catastrophic climate change that's wiped out humanity,” Bulletin president and CEO Rachel Bronson told CNN.
A haunting symbol born from regret, the Doomsday Clock was created in 1947 by the same brilliant minds who developed the atomic bomb. Albert Einstein, J. Robert Oppenheimer, and their fellow Manhattan Project scientists designed this warning system to alert humanity to the dangers they had unleashed.
Immediate impact of the Chernobyl accident. The accident caused the largest uncontrolled radioactive release into the environment ever recorded for any civilian operation, and large quantities of radioactive substances were released into the air for about 10 days.
On April 13, 2029 (which happens to be Friday the 13th), something unsettling will happen. A decent-sized asteroid, the 1,100-foot-wide Apophis, will pass so close to Earth it'll be visible in the sky from certain places. Crucially, the giant rock will not strike our humble planet.
We don't feel it because everything spins together, a motion that has lasted for 4.5 billion years. NASA says there's almost no chance Earth will stop spinning in the next few billion years.
A 300m-wide asteroid will not hit the Earth in 2036, US astronomers say. It was thought there was a one-in-200,000 chance that it could strike on 13 April 2036, but revised calculations have now ruled this out. Instead, Nasa scientists said it would not get closer than 31,000km as it flies past on this date.
Life expectancy (LE) in the U.S. is forecasted to increase from 78.3 years in 2022 to 79.9 years in 2035 and to 80.4 years in 2050 for all sexes combined.
The free website called Death Clock analyses personal data such as age, body mass index, diet, exercise levels, and smoking habits to predict the date of your demise as well as how you will die.
Differences in Adult Lifespan by Month of Birth. We find a similar relationship between month of birth and lifespan in both of our Northern Hemisphere countries. Adults born in autumn (October–December) live longer than those born in spring (April–June).
