The idea of 'no tilt/no seasons' is derived by a hypothesis from
Copernicus himself but the modified view replaces that view with
practical observations based on planetary comparisons where the cause
of the seasons is actually the orbital motion of the Earth and the
isolation of that motion and its characteristics.
If the earth had no rotational inclination (tilt), it's orbital motion around the sun would *not* produce variable seasons. That's why a tilt (to the orbital plane) is a necessary condition for seasons to occur. Copernicus was right, no tilt-no seasons.
A planet can have either Equatorial conditions such as the Earth or
polar conditions like Uranus based on what degree of 'tilt' exists but
of itself 'tilt' cannot cause the seasons,that dynamic is strictly the
specific way a planet orbits the Sun.The role of 'tilt' is therefore
restricted to seasonal characteristics and completely at variance with
the view of 'axial tilt to the orbital plane' or some such variation
of that theme -
Guess what, practically everyone here knows that it requires a combination of a fixed (in space) axial tilt (to the orbital plane) *combined* with the orbital motion of the earth during the course of a year, to produce the seasons. You must be the last one here to discover this.

I am not throwing good information after the 'climate change' mob whio
live and operate of a hyper fuss basis while not having any sense of
what causes basic temperature fluctuations of the day/night cycle due
to daily rotation or the seasonal cycle via orbital dynamics.
Is there any sane person,who can simply work out the reasons which
distinguish Earth from Uranus in terms of 'tilt' comparisons thereby
determining what role rotational inclination actually serves?.
I guess everyone here must be sane, because we all know how to make an accurate comparison between the earth's rotational axis and that of Uranus. If Uranus were a terrestrial planet, it would have very extreme seasons during an orbit of the sun because of the extreme tilt to it's orbital plane. There really is a connection between tilt (rotational inclination) and a planet's orbital plane. After all, the tilt angle has to be measured in reference to something. The orbital plane is that reference.

For all the fuss over 'global warming' and whether temperature spikes
are due to human or natural influences,until scientists explain the
basic seasonal temperature fluctuations correctly via astronomy and
planetary dynamics,they are being absolutely ridiculous in attempting
to correlate carbon dioxide with minor variations in temperature.
How intelligent do you need to be to understand what 'tilt' actually
does ?.
Apparently at least as intelligent as you, but there are many here who are much more so. That's why they understand much more than you do about orbital mechanics.
Here's that nagging question again. Why does the earth's rotational axis remain fixed in space towards the star Polaris? Why not some other direction or star? Have you made any attempt to look it up?
