Скачать или смотреть Why Is The Earth Rotating Faster Than Normal? Should You Be Worried?

It's been in the news recently that the Earth is rotating faster than normal, in fact some sources incorrectly state that the shortest day ever happened a few days ago. While it's true the Earth's rotation is over a millisecond shorter than normal, it's not as short at the 1.66ms difference seen last year.

There are all sorts of subtle global forces which affect the rotation of the Earth, not just the speed, but the location of the polar axis. And the effects of this are important for precision astronomy and navigation so there's a group that specifically tracks these effects
