The original assertion of Copernicus linking cause and effect between axial inclination and the seasons is somewhat below what is accurate for 21st century purposes -

"To this circle, which goes through the middle of the signs, and to its plane, the equator and the earth's axis must be understood to have a variable inclination. For if they stayed at a constant angle, and were affected exclusively by the motion of the center, no inequality of days and nights would be observed. On the contrary,it day or the of equal daylight and darkness, or summer or winter, or whatever the character of the season, it would remain identical and unchanged."
Copernicus

In many respects,this 500 year old assertion is played out in many classrooms by way of a teacher explaining that a planet with no tilt (0 degree inclination) would have no seasons much like Copernicus suggested however a slight shift in perspective changes the way an observer views the matter.A planet with 0 degree inclination would effectively experience equatorial conditions at all latitudes rather than the old 'no tilt/no seasons' perspective thereby allowing one end of a spectrum to emerge.A planet with 90 degree inclination would have a polar climate such as the planet Uranus with a roughly 82 degree inclination thereby bookending the climate spectrum between equatorial and polar.

So,instead of axial 'tilting' towards and away from the Sun,a smoother explanation emerges by allowing inclination to determine planetary climate conditions balanced between polar and equatorial inputs while allowing seasonal changes to emerge from the separate surface turning motion to the central Sun even if that orbital turning motion is not rotation in a strict sense.

This is not a game,the 'fire and brimstone' crowd that so diminished Christianity has moved to empirical circles where they now act out the same scaremongering with 'global warming' and get in the way of genuine pollution controls.It is already criminal incompetence to deny cause and effect between the daily rotational cycle and the daily temperature cycle as per the unfortunate people in the late 17th century who lost the plot with watches. Irrespective of the nuisances who show up here and drown out a decent discussion there would have to be people with some talent and a sense that all journeys to discovery can be chaotic sometimes and getting used to the new clmate principles is all that and more.
