The news should be that the core does not really rotate faster. Does it matter if it's one extra degree every million years? Some tectonic plate may move by that distance over the same time.
Um, yes it does matter. You do realize that businesses get sued because they don't fulfill six-nines availibility? A change in rate of 10^-6 is extremely important, especially in the geomagnetic fields where the rotation of the inner core needs to be precisely measured.
