Reply to comment by grishno 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
What’s there to be skeptical about? The core used to be slightly superrotating, ie. rotating a bit faster than the rest of the planet, now it has slowed down a bit and rotating at about the same rate as everything else, and it seems to be natural variation.
