Scientists have reported that the Earth"s rotation has accelerated, with days recorded as being 1.3 to 1.51 milliseconds shorter than the standard 24 hours on July 9, July 22, and August 5, 2025. This unexpected phenomenon raises concerns about potential global disasters.
While the exact reasons for the acceleration remain unclear, researchers suggest factors such as atmospheric changes, glacier melting, shifts in the planet"s core, and the weakening of the magnetic field could be contributing. If this trend continues, the consequences could be dire, potentially shortening days to just two hours, as depicted in Alex Foster"s novel "Circular Motion."
The implications of a faster rotation are alarming. Increased centrifugal force could distort ocean levels, leading to severe flooding in equatorial regions and shallower Arctic waters. Additionally, the acceleration may heighten tectonic plate movements, resulting in a higher risk of earthquakes. Hurricanes could also gain strength due to an enhanced Coriolis effect, while reduced daylight hours threaten to disrupt human circadian rhythms and satellite operations, impacting global communications and economies.
Despite these concerning possibilities, experts like Professor Duncan Agnew caution that significant acceleration of the Earth"s rotation is unlikely, noting no historical precedents for such a rapid change. In fact, the Earth"s rotation has been gradually slowing over billions of years, with a day lasting around 19 hours a billion years ago. As previously reported, the situation remains a topic of intense scientific scrutiny.
