One day in the next couple of years, everyone in the world will lose a second of their time. Exactly when that will happen is being influenced by humans, according to a new study, as melting polar ice alters the Earth’s rotation and changes time itself.
The hours and minutes that dictate our days are determined by Earth’s rotation. But that rotation is not constant; it can change ever so slightly, depending on what’s happening on Earth’s surface and in its molten core.
These nearly imperceptible changes occasionally mean the world’s clocks need to be adjusted by a “leap second,” which may sound tiny but can have a big impact on computing systems.
Plenty of seconds have been added over the years. But after a long trend of slowing, the Earth’s rotation is now speeding up because of changes in its core. For the first time ever, a second will need to be taken off.
“A negative leap second has never been added or tested, so the problems it could create are without precedent,” Patrizia Tavella, a member of the Time Department at the International Bureau of Weights and Measures in France, wrote in an article accompanying the study.
But exactly when this will happen is being influenced by global warming, according to the study published Wednesday in the journal Nature. Melting polar ice is delaying the leap second by three years, pushing it from 2026 to 2029, the report found.
“Part of figuring out what is going to happen in global timekeeping … is dependent on understanding what is happening with the global warming effect,” said Duncan Agnew, professor of geophysics at the University of California San Diego and the study’s author.

The 2020s have brought a degree of chaos not seen in decades. A pandemic was followed by a full-scale war in Europe; both sent food and fuel prices surging. Extreme weather events have shown that climate change is beginning to bite. The phrase “unprecedented times” soon sounded too common.
This all affected the global standards of living. One measure of this, the United Nations’ Human Development Index (HDI), fell in 2020 for the first time since its launch. It fell again in 2021. The HDI is one of the most widely used measures of countries’ development, after the Gross Domestic Product (GDP). It is not complete, though. It does not account for economic inequality, for example, or disparities between ethnicities and genders.
The latest figures show that the global HDI is rising again, but progress has been slow and uneven. It seems the long-term trend appears to have suffered a permanent setback since the pandemic. This setback will deeply affect the world’s poorest.
Yet there are reasons for hope. The chaos of the 2020s has also shown that governments can collaborate on some big issues. During the pandemic, vaccines were developed, produced and distributed at remarkable speed, saving an estimated 20 million lives in their first year alone. At the 28th United Nations Climate Change Conference (COP28) in 2023 the world proved that it could agree on a deal to tackle climate change (even if fulfilling it is another matter). More of that will be needed to overcome the setbacks from the start of the decade.
