Earth's rotation slowing after record-short days, scientists predict

By PulseAugur Editorial · [1 sources] ·

Earth's rotation, which recently accelerated leading to record-short days, appears to be slowing down again. The shortest day of 2026 is predicted for July 26, measuring approximately 0.65 milliseconds shorter than a standard 24-hour day. This follows a trend of unusually rapid rotation observed since 2020, with 2025 recording a day 1.37 milliseconds shorter. Scientists attribute these fluctuations to various factors, including lunar orbits, tidal forces, and internal Earth movements, with some research also linking the gradual slowdown to climate change.
