are regarded as something mysterious, illusive, something that had happened in the distant past,
too distant for anyone to tell us about them, which rumours have it, may be repeated far in the future,
of which it is said that they develop slowly over thousands of years.
Ironically, a rigorously developed scientific factor has contributed
significantly to this mysticism.
assumed for a time, and this quite recently, that Ice Ages develop as the consequence of several minor long-term cyclical variations of
the Earth's orbit around the Sun. Thus, they are deemed to develop extremely
slowly, as these cycles are measured in tens of thousands of
years, such as the cyclical shifting of the tilt of the spin-axis of the Earth by 2.4 degrees
of over a span of 41,000 years. And while this is happening, the orientation
of the spin-axis is changing in cycles spanning
26,000 years, which in conjunction with the shifting of the eccentricity of the Earth's orbit in
100,000 year cycles, varies the distribution of solar exposure across
various areas of the polar regions.

It was believed for a time that the effect of the
combination of these cycles has to be the cause for the ice ages, mainly for
the lack of any other causative mechanics. However, the ice age
theories that are related to these cycles, known as the Milankovitch cycles,
fail to consider that the cyclical shifting of the tilt and the orbit, only
affect the seasonal and hemispheric distribution of the solar heat received,
while the total amount of solar radiation received on Earth remains always the
same regardless of how the Earth is tilted and its orbit is shifted. As a
result of this fundamental fact becoming acknowledged, the theory has become obsolete.
enormously deep glaciation of the Ice Ages that piles up so much ice on land
that the ocean level drop 400 feet, simply cannot reasonably be
regarded to be the result of seasonal and hemispheric changes in solar heat
distribution across the planet. The big climate changes therefore, evidently, have a bigger cause.
these cyclical variations, named the Milankovitch cycles, do indeed account
for some variations of the hemispheric and seasonal distribution of the incoming
solar radiation, the orbital variations however do not affect the total solar
energy received (see Ice
Age Precursors Part 2.) This means that other factors are involved that force the
known massive Ice Age cooling of the Earth by which ice sheets pile up more
than 10,000 feet deep over most of the landmasses of the Earth above the 40
degree latitudes, whereby the ocean level drops by more than 400 feet. Big factors
are required to cause these enormously big effects by which the Earth
becomes 30 to 50 times colder than it had been during the Little Ice Age in
factor that is big enough to cause the enormous climate fluctuations that the
ice core samples tell us of, is the Sun itself. With the Sun going inactive
below an input threshold level, a whopping 70% reduction in solar
energy emitted would result that would be a sufficient cause for these big
effects to occur.
tragedy of the mechanistic Ice Age myth is similar in nature to that of
Ptolemy's epicycles that were used to explain known and measurable
astronomical phenomena within the framework of prescribed assumptions. It took
astronomy well over a thousand years to liberate itself from the epicycles and
gain a correct perception. The prescribed assumption of the invariable-Sun has
the same imprisoning effect on the modern Ice Age theories. The still-ruling
scientific tragedy keeps the real Ice Age dynamics locked behind a closed
astronomy, where the epicycle results came close, but never matched the real
evidence, so do the computed epicycles of orbital mechanistics approximate the
observed evidence, but fail to match it.
for a larger image
to the computed exposures to the Sun, the last Ice Age should not have
happened as the mean average was way above the current exposure level.
Likewise we should have been in a new Ice Age for a long time already,
according to the computed exposure values. By the same token, the start of the
last interglacial started 10,000 years before the computed cause. This does
not happen in the real world. The slight approximation that exists, indicates
that the orbital variations are not the cause of the Ice Ages, but are
themselves effects of the very-large electrodynamics cycles that cause the Ice
Ages. Thus, for a realistic view, the electrodynamics factors need to be
considered for gaining and understanding of the Ice Ages.
