Astronomers,amateur or otherwise.

There are actual images of the Earth from space which show a more
complicated explanation for variations in daylight/darkness throughout
the year -

The present explanations using graphics from Solstice to Equinox based
on variable 'axial tilt' are almost monstrous where the rotational
orientation of the Earth 'straightens' up to split the circle of
illumination -

It is absolutely disconcerting to come across a people calling
themselves astronomers who can'y adjust to information pouring in from
images of Uranus and the Earth from space,animation and graphics to
demonstrate how a location will behave orbitally as it orbits the Sun
and quite apart from axial rotation.

All these fine people working on climate modelling and it is useless
if they can't even explain variations in daylight/darkness let alone
the seasonal weather patterns attached to them.I have no idea what is
needed to break this drowsy condition where nothing is being done,not
for any sake of urgency but that the actual explanation for the
seasons is absolutely enjoyable after a small initial effort.

It is a 100% geometric certainty that a location on Earth turns
through 360 degrees with respect to the central Sun over the course
of an annual orbit and replacing the pseudo-dynamic of variable tilt
and its absence of any 360 degree feature.If this modification of
Copernican reasoning does not happen then astronomy is truly finished
for generations .
