The Earth’s rotation speed is increasing, with scientists predicting that in 2025, the planet will experience three days shorter than average by as much as half a millisecond.
According to data from the International Earth Rotation and Reference Systems Service (IERS), the three shortest days this year are expected to be July 9, July 22, and August 5. These dates coincide with when the Moon is furthest from the equator, which impacts the speed of the Earth’s rotation.
In the past five years, the Earth’s rotation has shown a trend of increasing speeds, with scientists noticing that it’s now more likely to see days during the summer as being shorter than usual. This trend is expected to continue in 2025.
The cause of this acceleration is still unknown and is believed to be related to internal factors within the Earth, such as ocean and atmospheric models not being able to explain the phenomenon. However, scientists agree that the planet’s rotation will eventually slow down due to natural processes like polar ice melt, but the current trend is a sign that things are changing rapidly.
As our planet continues to evolve, it’s essential to stay informed about these changes to better understand our world and its complexities.
