(CNN) Earth’s inner core may have stopped turning and could go into reverse, study suggests.
This is baloney. The cited study, Multidecadal variation of the Earth’s inner-core rotation, claims no such thing. Quoting from the abstract,
Differential rotation of Earth’s inner core relative to the mantle is thought to occur under the effects of the geodynamo on core dynamics and gravitational core–mantle coupling.
The word in red is omitted. CNN, you could have used “relative.”
The difference in the speeds of rotation of the inner core and the mantle, regardless of direction, is about that of a near-frozen inchworm. If you were looking at it, you would see nothing.
How much must be lost in translation?
