Reply to comment by Cobra800089 in What are the forces on Earth’s Inner Core that change its speed? by BayRunner
thanks. i must have mis-read recent news articles that stated that the core had reversed its spin and was now spinning in the opposite direction. this implied to me that the field reversal must have already happened in short order and so we would have seen the effects of that weakening here on the surface.

There is a difference between the inner and outer core. The inner core is approximately solid while the outer core is liquid and is the region that produces the geodynamo. The geomagnetic reversals are more related to the fluid motion in the outer core than the rotation (and/or differential rotation) of the inner core.

I'm not going to blame you, the media coverage on this has been atrocious. Willfully misleading I'd say

one expects sensationalism out of the National Enquirer, but not from so many of the more (formerly) respected outlets that covered this story. everyone's out for click-bait it seems.
