Experts have observed that Earth's rotation is speeding up, making some days slightly shorter than the standard 24 hours.

Earth is spinning faster than ever, and the result is a shortening of the length of our days. Since 2020, each year has brought records for the shortest day ever, with Earth’s spin accelerating ...

In recent years, the Earth’s rotation has been speeding up due to dynamics in the planet’s liquid outer core. This increase presented the possibility that scientists might soon have delete a ...

While the Earth’s rotation changes over cosmic timescales, it also fluctuates on daily ones. We all know that a day lasts 24 hours, or 86,400 seconds, but that’s not perfectly accurate.

Fotheringham spoke of the importance of the fact of rotation in regard to such practical matters as the alternation of day and night, the march of the seasons, the tides, and the measurement of time.

Global warming caused by climate change is shifting how quickly the Earth's rotation is speeding up and affecting the time we keep, according to a study published Wednesday.

Climate change is causing so much polar ice melt that it's slowing down Earth's rotation and it will alter how we measure time in the future.

But that rotation is not constant; it can change ever so slightly, depending on what’s happening on Earth’s surface and in its molten core.

Melting polar ice is changing the Earth's rotation and affecting how we measure time: Study Coordinated Universal Time (UTC) may lose a second for the first time.
