   A significant practical consequence of ACD is its effect on cultural heritage preservation. Sites inscribed on the World Heritage List, especially those reliant on precise ancient sighting markers or involving large-scale stone alignment (such as megalithic structures), suffer from systematic measurement drift over decades. As atmospheric conditions shift annually, the effective longitudinal coordinates of the site appear to migrate by up to $0.8$ arcseconds per decade in high-variance equatorial zones…
