That's silly.  Think about it.  If the seasonal
change is uniform, then you'll be swapping same
for same, with no resulting difference.

No swapping is necesary for seasonal change Greg,
even with no tilt, Earth would still have seasons,
but without the eliptical orbit, Earth would not.

Well, that's true enough.  But they would be just

about opposite to what we have now (hottest during
our winter and coolest during our summer), and the
size of the variation would be miniscule, maybe a
couple of degrees average variation over the year
for a given location.



the tilt does "enhance it", but it is not the cause".
the orbit is the cause, the tilt is the enhancement.

Nope.  The major component of the seasons is caused
by the tilt.  Do the energy balance calculation, James.


'Tilt' is nothing more than axial rotation,if there were no axial
rotation there would be no ' tilt' therefore axial 'tilt' is not a
thing in itself In fact,the more accurate term is rotational
orientation,the fact that the Eatth spins, points in one direction in
space and causes day and night covers the limits of axial rotation but
somehow you give it a magic property to cause seasonal variations in
daylight/darkness.

The real point of this thread is what action causes the seasonal
differences in daylight and darkness,you say 'tilt' and the real
answer is a seperate motion attached to the orbital motion of the
Earth,a simple 360 degree motion a location has as it swings around
the central Sun.

I am delighted to see you place so much on 'tilt' but thgat is as far
as it goes



















Incorrect.  The length of daylight hours and angle
of incidence of the sun's rays at any given place
on the plaent is an effect of the tilt.

nope,
that is the effect for the seasonal swap.
not the seasons themselves.
again, you need to remove the dang tilt and think
instead of just a "read only memory" use.

I've done both, James.  That's what comes of reading to
understand rather than to entertain.

LOL
You have not checked it out enough without reading Greg.
LOL

Without the eliptical orbit the seasons would be gone
even with the tilt left.

Well, you're definitely wrong on this point, as the
calculations would show you.  That you are of a fixed
mindset regarding it only highlights your characteristic
denial of inconvenient (to you) facts.

Hey James, why do suppose it is that people using
photovoltaic cells to produce elecricity take care
to aim their solar panels so that they are
perpendicular to the Sun's rays?- Hide quoted text -
