Be my guest.using the same graphic what do you change to have the
geographical axis line up with the Solar radiation/Orbital shadow (SR/
OS) boundary while keeping rotational orientation fixed to Polaris -

http://www.astronomy.org/programs/se...flashlight.gif

The modification to Copernican reasoning based on the pseudo-dynamic
of variable axial tilt is now far more important than the Keplerian
orbital refinement,specifically in order to split global climate from
hemispherical weather patterns (seasons).With all the grave concerns
about climate,the unusual situation is that we do not even have an
accurate explanation for the seasons and that is probably the only
conclusion that can be drawn at present.

To alter the SR/OS boundary is an enormous challenge in itself
therefore to make variable axial tilt align with the SR/OS boundary at
the Equinoxes is a waste of time even if it still is proposed as a
pseudo-dynamic. Who wants to help humanity understand the difference
between global climate and hemispherical weather patterns with the
help of modern imaging and the correct astronomical mechanism for
climate and the seasons ?.

That's right,you would rather show each other pretty pictures and
pretend that astronomy is all about magnification.

Seasons occur on the Earth because of the tilt of the Earth's axis.
Because the Earth's spin is not exactly aligned with the Earth's
orbit around the sun, the Sun sometimes shines directly over the
northern hemisphere, and other times shines directly over the southern
hemisphere. For instance, the sun reaches its most northerly position
(the tropic of cancer) on June 21. This is called the "summer
solstice." If you were standing on the tropic of cancer on June 21,
the sun would be directly overhead at noon. This is the first day of
summer in the northern hemisphere, and the first day of winter in the
southern hemisphere. Because the sun is shining more directly in the
north than in the south, the weather is warmer in the north in June.
In December, the opposite happens. The sun is over the tropic of
Capricorn, and is shining directly at the southern hemisphere. So
December is summer in Australia and Brazil, but winter in America,
Europe, and Asia.

Some people believe that summer is when the Earth is closest to the
sun. This is not true. In fact, the Earth is farthest from the sun in
early July,


The challenge is actually a waste of time when you know the answer
and the cause for cyclical hemispherical weather patterns is certainly
not variable inclination of the Earth as the following graphic would
have it -

http://www.astronomy.org/programs/se...flashlight.gif

All this fuss over climate imbalances and global warming and I have
yet to see a correct explanation for what causes cyclical weather
patterns in the hemispheres and all encompassed by global climate and
the motions of the Earth.The price of your observational convenience
based on celestial sphere geometry and your magnification hobby is the
inability to work with the axial and orbital motions of the Earth as
they apply to climatology and so much else.

Seasons occur because of the majestic motions of the
Earth,specifically the change in the Orbital shadow/Solar radiation
boundary against rotational orientation.Of course,this majesty is
availible to astronomers while variable axial tilt is for those who
know no better,at least with 21st century imaging and data.

The motions of Earth and its orbital position from the Sun dictate
the background for global climate and what makes existence
possible,in fact most people are astronomers by living by the daily
and annual cycle of the Earth.For you magnification folk,you probably
notice that people are interested in astronomy through climatology and
are paying closer attention to the planet after being bombarded for
decades with huge sweeping statement about the universe.

Google news is full of astronomical content even though astronomers
are absent from the discussion.

http://news.google.com/nwshp?ie=UTF-...ncl=1114966083

Your reaction is expected just as Sam's standard stock reply is and
the theorists poor attempt to argue for a variable tilting Earth.What
is not expected,but hoped for,is a courageous person who has enough
sense to see where astronomy and climatology mesh and make the
neccessary modifications to suit 21st century concerns.

That's the first day of *astronomical* summer/winter. There are meteorological
definitions of the seasons too. Since they depend on the weather, the dates
of the start of the meteorological seasons vary with both place and year.

That's during winter in the southern hemisphere.

There is no challenge... This is the way the seasons work.- Hide quoted text -

Here are the temperature bands which set the conditions for global
climate -

http://www.climateprediction.net/ima...ges/annual.gif

The oscillation of those temperature bands over the course of an
annual orbit of the Earth depend on how long a location spends in
solar radiation or in the orbital shadow as the main component.

Hemispherical weather patterns or the seasons as you know them are a
distinct hemispherical subset of global climate insofar as weather
conditions of temperature,precipitation and the nature of the
precipitation (rain,snow) atre due to the conditions set by the
orbital cycle of the Earth .

You do not try to explain hemispherical weather patterns directly
through the motions of the Earth (hence your variable axial tilting
Earth),what you do is explain global climate using the orbital motion
and path of the Earth and determine that the SR/OS boundary alters
against rotational orientation.

Right now you have a bunch of guys fixated on CO2 levels and making a
good job of scaring people with future predictions,these same people
do not even explain the known cyclical hemispherical weather
patterns( seasons) for the Earth correctly or rather use a pseudo-
dynamic of variable axial tilt to do the job that the Earth's orbital
motion does.

At the bottom of it all was the late 17th century analemmatic fudge
introduced by celestial sphere geometers to destroy heliocentric
reasoning and the Equation of Time principles which correlate the
total length of the natural daily cycle with the human devised
principle of the 24 hour cycle.

http://imagine.gsfc.nasa.gov/docs/as...s/980116c.html

The Equation of Time has nothing whatsoever to do with hemispherical
daylight/darkness asymmetry,the seasons or variable axial tilt as the
above explanation would have it but it is almost totally a consequence
of the longitudinal change in the SR/OS boundary in accordance with
Keplerian orbital geometry.To get people to recognise the change in
that boundary would be a major achievement for climatology let alone
astronomy.

There is no sense here that anything is wrong with a variable axially
tilting Earth,not the slightest sign of recognition that there is a
productive way to split global climate from hemispherical weather
patterns (seasons) and explain the former astronomically and allow the
latter to exist as a meteorological prediction convenience.

I am well familiar with the politics of all this and have nothing to
say about what will occur as the 'theoretical' excesses of the last
century are set aside for the new agenda of climate 'predictions' and
all its dire warnings.My policy is making people aware of the
terrestrial consequences of the motions of the Earth and how the
cycles makes existence possible,cycles that you lot spent centuries
ignoring for the convenience of celestial sphere geometry and
observational predictions based on the calendar system.Considering
that in all the years promoting the system where clocks keep in sync
with axial rotation in 24 hours/360 degrees reflecting the daily
rotational cycle of the Earth via the human devised Equation of Time
principles that I have yet to see one person affirm it,makes the
appreciation of the more intricate astronomical/climatological
material less likely now than ever.
