Direction of the Earth's axis tilt in the x-y ecliptic plane?

Dear oh dear oh dear,

This business of axial tilt causing summers and winters sounds great ,
even Copernicus held to the belief, but unfortunately it is incorrect .

Keep axial orientation fixed and forget about the celestial
sphere,North poles and Solstices.

The change in orbital orientation is due to the orbital motion of the
Earth,no big surprise or difficulty with that.

Keep things local and you have a global view of seasonal changes based
on climate bands straddling the Equator from tropical to temperate to
Artic.Split the Earth into hemispheres and retain the dumb notion of
variable axial tilt against the Sun or orbital plane and remain part
of destructive group of people who are hindering the effort to
understand climate imbalances.

Keep trying with the material because you will eventually come round
to the correct astronomical mechanism for cyclical seasoinal changes or
go insane trying to give the Earth a variable axial tilt when it has
none,neither to the Sun or Obital plane.This is important so make sure
you get it right.

It would be much more productive in general and insightful for all of
us if you would spend your time in taking a serious crack at writing
this accurate description that you claim is so clear to you.

Take some responsibilty.

Do you clearly understand why it is not a good idea to split the Earth
into two hemispheres when describing the astronomical mechanism for
cyclical seasonal variations -

The cataloguers of the 17th century broke several working astronomical
principles to get terrestial longitudes to fit into the sidereal Ra/Dec
system ,a great convenience for optical astronomers but prove to be
lethal to the working principles of climatology and the pressing need
to come to grips with climate imbalances from cyclical seasonal norms.

If people insist in retaining variable axial tilt or indeed variable
Equatorial orientation to the Sun as a hemispherical means to explain
seasonal variations ,you can forget expressing concerns for the
enviroment and concern for future generations because of our actions.If
you cannot figure out the astronomical basics of what is fixed and what
is moving,in this case changing orbital orientation against fixed axial
orientation,then we are in a worse state than even I imagined.I refuse
to believe people would believe in a hemispherical Earth mechanism for
seasonal changes even though they currectly promote it.

So no, you're not really interested in authoring a clear, concise
definition of your universe. You'd rather stroke your ego into
grandeur by whining that you have a uniquely clear perception,
bemoaning the dearth of reason to back you up.

Do you clearly understand why it is not a good idea to complain that
something you supposedly understand so well has not been explained,
yet refuse to do so yourself?

Worthless posts, waste of time for us, and life on you.

Considering what is at stake and that the contemporary majority view
is based on non existent variable axial tilt to the Sun/Orbital
plane,I still have to find genuine people who are embarrassed enough to
call into question the stupid working principles that take the name of
astronomy and astronomical methods.

Tomorrow you will wake up as a guy who celebrates a system based on a
hemispherical Earth, a system where the Sun bobs up and down against
the Equator -

The actual mechanism for seasonal changes is on a different level to
the simpleminded 17th century cartoon creations you and your
colleagues adhere to and without a proper appreceation of how to assign
priority to the respective motions and orientations,all your concerns
for climate imbalances will be as phony as the stupid working
principles you adhere to.

I do not insult you,you use hemispherical Earth working principles so
you insult yourselves.

The only way for this sequence to happen would be if the north tilt were
backward (opposite the direction of movement around the sun) at the
vernal equinox and, of course, toward the direction of orbital motion
at the autumnal equinox. Dave

Thanks for your patience, Dave. My reasoning route is more circuitous
and unnecessarily complicated. I have read the simplier explanation
that you recite, which dates back to the ancient Greeks, and have seen
diagrams of the Earth's orbit illustrating it. But somehow, I was
having some problems visualizing the relationship between the orbital
direction and tilt, "in the field" so to speak, while standing facing
south on the vernal equinox.

Now only if there was a very bright star conveniently positioned at the
North Ecliptic Pole and that was visible during the daytime. -

P.S. - With the more generalized NEP-NCP solution, I can now go to
school sun parties on any given day and at noon, with some confidence,
say to the kids - "We are tilted that'a there way." -
