Earth is spinning too fast — the consequences for timekeeping may be unprecedented

Science Earth is spinning too fast — the consequences for timekeeping may be unprecedented The answer could come from deep below. Our home planet is in a hurry. On June 29, 2022, Earth completed the shortest day since scientists started keeping records in the 1960s, pulling off a full rotation 1.59 milliseconds faster than usual. Terrestrial haste is a trend. In 2020, the planet recorded the 28 shortest days on record, and it kept spinning rapidly into 2021 and 2022. Before scientists could even verify that record-setting day time of June 29, our world almost outdid itself: It blazed through July 26, 2022, 1.50 milliseconds ahead of schedule. We will likely see more record-short days as Earth continues to accelerate, says Judah Levine, a professor at the University of Colorado-Boulder …
