Earth shifted on its axis5/4/2023 Climate Change Has Now Invisibly Shifted Earth’s Axis, New Data Reveal In each of these, the magnetic poles of Earth shifted by approximately 55° – from a large shift in the crust. Between approximately 790 and 810 million years ago, when the supercontinent Rodinia existed, two geologically-rapid phases of true polar wander may have occurred. A characteristic rate of true polar wander is 1° or less per million years. Research shows that during the last 200 million years a total true polar wander of some 30° has occurred, but that no super-rapid shifts in Earth’s pole were found during this period. However, in what is known as true polar wander, the solid Earth can rotate with respect to a fixed spin axis. ![]() There is evidence of precession and changes in axial tilt, but this change is on much longer time-scales and does not involve relative motion of the spin axis with respect to the planet.

This article is about the hypothesis of pole shift in its historical context.
