Earth’s rotation is expected to speed up this year, resulting in shorter days. According to a new report, July 9, July 22, and August 5 will be the shortest days, with differences of around 1.51 milliseconds from average.
This acceleration is unusual, as Earth’s rotation has been slowing down due to the Moon’s gravitational pull over time. However, scientists believe several factors could contribute to this change. These include movements within the Earth’s core, redistribution of mass from melting glaciers, and El Nino and La Nina events.
Experts say that adjustments to global timekeeping might be necessary as a result of this acceleration. One possible solution is subtracting a leap second for the first time in 2029. The cause of this acceleration remains unclear, with most scientists believing it’s related to something inside the Earth rather than ocean or atmospheric models.
