precession

This is due to what is known as "precession;" a slow movement of the axis upon which the earth rotates.

Does the precession of the equinoxes have any effect upon the seasons or upon the climate of different parts of the earth?

Will the precession ever bring back the right ascensions and declinations to be again what they now are?

This slow movement forward of the goal-post is called precession—the precession of the equinoxes.
