Ice Age Solar variation  

- Enabling the Inevitable

Ice Age by Solar Winds

consequently, neither is the heliosphere
and with it the climate on the Earth

 

How solar variation cause mayor climate variation?

Since the 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.

The space 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 continuing that the Sun may go inactive with which the long-expected Ice Age begins.
