How hard is it (apart from the usual nuisances who reply) to determine
what role rotational inclination (tilt) actually plays and that it
does not cause the seasons ? .

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.

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 -

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?.

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 ?.
