A new study suggests that changes in inner core rotation rate might be linked to ever so slight changes in the length of a day. This is not enough time to have an extra cup of tea in the morning, these are really, really tiny changes. We're talking about changes which are maybe a tenth of a millisecond in the lengthof a day. So they're tiny, tiny fractions. And maybe 30 years ago, the inner core was just moving an ever so slightly different speed to the rocky layers of the earth. That's the big takeaway. It does have some side effects though, and it has effects when we think about things that maybe were a bit more used to thinking about like
