Default Satellite views of orbital orientation

The deviation between axial and orbital orientations are presently
almost at their maximum and minimum as terrestial longitudes passing
through the line denoting the orbital orientation of the Earth mesh
with each other at dawn and dusk while at noon,the deviation is at its
maximum of 23 and a half degrees.

The event is annually unique insofar as the relationship between axial
and orbital motions are asymmetrical from Mar to Sept as compared to
Sept to Mar,not from a hemispherical view but from a true global view.

The slight adjustment to viewing changing orbital orientation against
fixed axial orientation rids genuine investigators of the really
embarrassing view of viewing cyclical seasonal norms from variable
axial tilt against the Sun or orbital plane involving hemispherical
Earth descriptions.

It is time for astronomers to help people appreceate the astronomical
mechanism for cyclical seasonal climate variations using a 21st century
view rather than the erroneous hemispherical view .It is one thing to
express concern for climate imbalances with working principles which
take account of climate bands which straddle the Equator and move to
the poles from temperate to Artic,it is quite another to split the
globe into seperate hemispheres and try and work with climate change
that way.

The Equionox alignment is enjoyable but that luxury should be set aside
for the working principles which emerge from taking it in terms of a
global view rather than a hemispherical split in seasons.Nobody is
going to claim priority for that is not the point,it is a matter of
making the effort to help frame global climate imbalances in an
accurate framework involving the best of human reasoning whether
astronomical or terrestial.
