The length of an Earth day is changing, and you probably haven't noticed. Not by minutes or even seconds, but by tiny fractions of a second. The main reason is the Moon, whose gravity raises tides in ...

Climate change is lengthening our days because rising sea levels slow Earth's rotation. Researchers from the University of Vienna and ETH Zurich now show that the current increase in day length—1.33 ...

Scientists may have solved why the length of Earth’s day changes by a few milliseconds over decades. Subtle shifts in the inner core appear to tug on the mantle, revealing a surprisingly dynamic world ...
