Original Note:
The inner core rotates in the same direction as the rest of Earth, but cycles between going slightly faster or slower (<1° difference/yr) every ~35 years. This natural cycle is only known through precise geophysical study; it does not cause noticeable changes at the surface. https://www.nature.com/articles/s41561-022-01112-z https://www.washingtonpost.com/science/2023/01/23/earth-core-slowing/
