Earth to Spin Faster, Resulting in Shorter Days in July and August
The Earth is going to spin a tiny bit faster on certain days in July and August, making those days a bit shorter.
It's like the Earth is giving itself a little boost!
This is unusual because Earth usually slows down.
Scientists think things inside the Earth, melting ice, and even the weather might be causing it.
It could mean that we might have to take a second off our clocks in the future!
Earth's rotation is expected to speed up in July and August, resulting in shorter days.
July 9, July 22, and August 5 are predicted to be the shortest days.
The shorter days will be measured in milliseconds.
Factors like Earth's core, melting glaciers, El Niño/La Niña, and the moon might influence the rotation.
The faster rotation could lead to subtracting a leap second in 2029.
