solar variation cause mayor climate variation?
Sun has been proven to be constantly changing, it is not unreasonable to assume
that the long-term climate changes, such as the ice ages, are effects of
major, long-term solar activity variances. If the power flowing into the Sun is fluctuating, its associated 'space weather' pattern is also
fluctuating. The Sun creates its own 'weather' as it were, determined by the
intensity of the solar winds that flow out from it, resulting from the
energetic, electric reaction that lights up the Sun.
weather is contained within the solar-created environment called the
heliosphere. As the solar winds flows away from the Sun, they are electromagnetically
accelerated to speeds greater than a million kilometers per
hour. Near the interstellar medium app. ten billion kilometers distant,
the solar winds slow down.
The zone where this happens is called the " termination shock."
The point where the interstellar medium and solar wind pressures
come into balance, whereby the solar winds are stopped, is termed the "heliopause."
The final zone, further away, where the interstellar medium, moving in the opposite direction,
begins to slow and collide with the heliosphere, is termed the "bow shock."
This three-layer zone, far past the orbit of Pluto, is critical for our climate
on earth, because it is here where the interstellar cosmic background radiation,
consisting of immensely energetic protons, electrons, and ions (the cosmic rays)
becomes attenuated. The density of the termination shock, the heliopause, and
the bow shock determines the density of the cosmic-ray flux that penetrates this barrier. When the solar power activity is high, the barrier is more dense,
and correspondingly fewer cosmic rays get past the barrier. Inversely, when the
solar power activity is low,
the solar wind pressure is lower, the barrier is weaker, and penetrating
cosmic-ray flux is stronger.
Studies have revealed patterns of cyclical
variations in cosmic-ray flux that peak in synchronism with the deep glaciation
periods of 450, 300,
and 150 million years ago, and also with the modern glaciation period. However,
these periods of high cosmic ray flux are not the cause of the ice ages. They
are subsequent effects of the Sun going inactive so that the Heliosphere does
not exist during such times. As the result, the Earth receives the full, un-attenuated
impact of cosmic rays during the long periods of the cold, inactive Sun. We are
moving towards that presently, with the Heliosphere getting progressively
weaker. NASA's Ulysses spacecraft had measured a 30% drop over 10 years to 2009,
in the solar wind pressure that 'inflates' the Heliosphere. 30% is big for such
a short time. It is highly possible that in 3 to 4 decades of this trend
