Scientific communities are facing a unique phenomenon – a drastic reduction in the duration of the day, which calls into question previous understandings of planetary dynamics. Experts from the International Council for Rotation and Reference Systems have documented an exceptional case of acceleration in Earth's rotation.
On July 9 and 22, as well as on August 5, 2025, the daily duration has decreased by an impressive 1.51 milliseconds. This result is the shortest measured period since 2020, surpassing even the previous record from July 2024.
According to scientists, the causes may lie in internal planetary processes that remain outside the scope of traditional oceanic and atmospheric models.
An additional factor could be the specific positioning of the Moon relative to the Earth's equator, which contributes to unusual fluctuations in the planet's rotation.
Expert forecasts indicate that if this trend continues, there is a high probability that the first "negative leap second" will be introduced by 2029. Duncan Agnew from Scripps Institution emphasizes that although rare, such a phenomenon does not represent a catastrophic scenario, but rather an interesting scientific case.
