Doomsday clock moved to 85 seconds to midnight

The Doomsday Clock has been adjusted to its closest position ever to midnight, signaling heightened global risks. The Bulletin of the Atomic Scientists announced this update, emphasizing threats from nuclear weapons, artificial intelligence, biosecurity, and climate change. Experts urge immediate action from world leaders to mitigate these dangers.

The Doomsday Clock, a symbolic gauge of humanity's proximity to global catastrophe, now stands at 85 seconds to midnight. This marks the nearest it has ever been to the symbolic hour of doom since its inception nearly 80 years ago. The adjustment was made by the Bulletin of the Atomic Scientists’ Science and Security Board (SABS), the panel of experts responsible for annual updates to the clock's position.

Created in 1947 amid Cold War tensions, the clock serves as a warning about existential threats. This year's setting reflects escalating concerns identified by the SABS. They pointed to the growing threat of nuclear weapons, disruptive technologies like artificial intelligence, multiple biosecurity issues, and the ongoing climate crisis as key factors pushing the hands closer to midnight.

The board's statement underscores a troubling trend: catastrophic risks are on the rise while international cooperation appears to be waning. "Swift action is needed from global leaders to correct course," the announcement emphasized, calling for renewed efforts to address these interconnected dangers.

This update comes at a time when geopolitical tensions and technological advancements amplify uncertainties. The clock's position is not just a metaphor but a call to vigilance, reminding policymakers and the public of the fragile balance maintaining global stability.

Since 2007, the end of daylight saving time has come the Sunday before U.S. elections in November, putting Election Day two days after the time change. Research links the fall switch to short‑term upticks in depression and shifts in road safety; studies of turnout show small, context‑dependent effects.

Nobel Peace Prize laureate and Rappler CEO Maria Ressa will speak at the Bulletin of the Atomic Scientists' announcement of the 2026 Doomsday Clock on January 27. The clock symbolizes how close humanity is to catastrophe from risks like nuclear threats, climate change, and disruptive technologies. In 2025, it was set at 89 seconds to midnight.

Physicists at UCLA have devised a straightforward method to create ultra-precise nuclear clocks using minimal amounts of rare thorium, borrowing a technique from jewelry making. By electroplating thorium onto steel, the team achieved results comparable to years of complex crystal fabrication but with 1,000 times less material. This advance could enable reliable timekeeping in GPS-denied environments like deep space and submarines.

A new analysis in Geophysical Research Letters shows Earth warming at ~0.36°C per decade since 2014—about double the prior rate of 0.18°C per decade—with 98% confidence after accounting for natural factors. Led by Stefan Rahmstorf, the study warns the Paris Agreement's 1.5°C limit could be breached by 2028, amid debates over short-term trends and data uncertainties.
