GPS/SLR Secular Polar Drift (Glacial-Rebound Driven)
mechanism
The Earth's poles are drifting, but the reason is melting ice rebounding, not the planet's core coming loose.
Who they are
The slow, measured wandering of Earth's poles as tracked by precise satellite positioning.
What they do
It's the documented small drift of the poles over recent decades.
How it works
High-precision space measurements (GPS and satellite laser ranging) show only about 31.5 inches of pole shift since 1993, caused by the ground slowly rebounding after ancient glaciers melted and by density differences deep in the Earth — not by the core physically decoupling.
Why it matters
It provides the mainstream, evidence-backed explanation that rules out dramatic 'the crust is slipping' catastrophe claims.
The engine's record — word for word
High-precision space geodesy (GPS, Satellite Laser Ranging) shows only 31.5 inches of secular polar shift since 1993, driven by post-glacial viscoelastic rebound and mantle density anomalies — not core mechanical decoupling. [TIER GEOPHYSICS-PEER-REVIEW; Apex (a)] [Report #103 (ECDO)]
