Q: (Gaby) TES (The Ethical Skeptic) has a hypothesis based on these blobs and posits that Earth's core and mantle dynamics drive periodic rotational instabilities, leading to true polar wander events.

Exothermic Core-Mantle Decoupling - Dzhanibekov Oscillation (ECDO) Theory]
A: Partly involved, yes.
Q: (Gaby) He claims that a weakening of the core mantle magnetic coupling causes heat from the Earth's core into the mantle, excluding these blobs. This makes the rest of the mantle denser than the blobs, contributing to:
- Loss of current influence in the position of our geographic North Pole
- Increase in sea surface temperature and in the Earth's axis of rotation
- Shift in the planet's rotation around its maximum axis (the denser mantle)
- Increasing the chances of a True Polar Wander event with an axis of gyroscopic moment based upon the African blob.
A: Very close!
