Earth science: Is it true that the earth's core might have stopped rotating? If so, what are the consequences?

​

Also, how is it that magnetic poles move, and can become inverted? And besides messing up with compasses, what would be the consequences of such a big move?

​

Finally, we don't hear about the ozone layer much anymore. What's going on with that? is it fully healed?

According to one recent paper the Earth's core might have stopped moving relative to the surface, which is to say it's still rotating as fast as the surface is. From an outside perspective, essentially the core is going from rotating slightly faster than the surface to slightly slower. Per the paper, this happens pretty regularly and won't do much.
