Reply to comment by james_randolph in Earth's inner core may be slowing down, but “Nothing cataclysmic is happening,” says Hrvoje Tkalcic, a geophysicist at Australian National University. “The inner core is now more in sync with the rest of the planet than a decade ago when it was spinning a bit faster.” by clayt6

It might be slower a decade from now, and then the fact that it's slower than the rest will make it speed back up again. It's likely just a slow oscillation between faster and slower as the moving liquid outer core stops it from ever being truly in sync.
