Scientists,in describing the cause of seasonal change,are focusing on
the wrong orientation for common sense dictates that the axial tilt is
fixed as does not change -

Assuming people would actually like to know what causes seasonal
changes from a global rather than a hemispherical perspective,the
answer lies in the changing orbital orientation to the Sun.
Equatorial orientation or hemispherical variations in the Sun's
altitude is a chronic symptom of that awful maneuvering by 18tyh
century cataloguers.
At other times you could all sit back and pretend not to see but it
really,really does not take much to see how orbital motion and
orientation changes against a fixed axial orientation.If you are so
dumb that you imagine a non existent axial tilt component to the
orbital plane as an explantion for seasonal changes then be my guest
because although the variation is orbital orientation is initially
tricky to become famaliar with it becomes an easy and comfortable
explanation after a while.
Your empirical explanation,otoh,sticks out like a sore thumb.
