Ice ages are digital events. Nothing else makes sense. Nothing changes gradually here, on the climate landscape, as the benthic climate records from deep sea sediments tell us. Shown here are the last four Ice Age cycles.
The ice core records tell us essentially the same story. The climate recorded in ice cores flips radically between glacial states and interglacial states in an on-off fashion.
The ice core records tell us that the deeply cold glaciation climate, which had been the norm for the last 400,000 years, had been interrupted periodically with warm interglacial periods of short duration, with sharp transitions between them, and a contrast so great that we are looking at two totally different environments, similar to a lamp being turned on in a room, or off. The archaic theory of the Milankovich cycles cannot produce these phenomena.
The archaic theory supposes that minute cyclical variations of the orbit of the Earth around the Sun, and its shifting spin axis, in combination, affects the amount of solar radiation received on earth. While this is true, the cyclical variations only affect seasonal and hemispheric distribution.
The theory ignores that the total energy received from the Sun remains the same,no matter how far the spin axis is tilted, or is oriented, or the eccentricity of the Earth's orbit varies.
The archaic theory becomes discredited by the evidence that ice ages are not hemispheric phenomena, but global phenomena occurring simultaneously in the North and in the South. When an Ice Age begins, the entire planet goes into a deep-freeze mode.
Only dramatic changes in the operation of the Sun can cause the enormous climate differentials between interglacial and glacial climates, that we have records of.
Actually the term 'enormous' is too small a term to describe the difference. Ice core records tell us that the difference from interglacial climates to glaciation climates adds up to 70% less solar radiation emitted by the Sun.
In turn, the 70% weaker Sun gives us 80% less precipitation. Much of the Earth becomes a desert when this happens. But how can the Sun change so enormously in one single step with a sharp transition between the states?
The answer is rooted in the Primer Fields that focus high-density plasma unto the Sun.
When the input plasma density drops below the needed level for the Primer Fields to be maintained, the Primer Fields vanish as if they had never existed. In this case the Sun looses its high-density plasma shell around it, with the result that less energy is being produced by the Sun.
Without Primer Fields, the Sun goes into a state of hibernation, as it were. While the plasma streams still flow past the Sun, the reduced plasma-density reduces the solar radiation by potentially 70%.
Ironically, the hibernating Sun emits dramatically larger volumes of solar cosmic-ray flux, even while it's radiated energy is 70% weaker. This is so, because the hibernating Sun is no longer surrounded by the dense shell of plasma that it presently has in its high-powered mode, which blocks a large portion of the solar cosmic-ray flux. When this shielding plasma shell no longer exists, the full volume of the Sun's cosmic-ray emissions will then be felt on Earth. Ironically, the full volume of solar cosmic-ray flux is larger coming from the hibernating Sun, than is the attenuated volume coming from the high powered Sun, as we have it today.
And this is precisely what we see evidence of in ice core samples from Antarctica in the form of Berillium-10 ratios. Beryllium-10 is a radioactive isotope that is exclusively produced by cosmic-ray interaction with the Earth atmosphere.
The plotted ratios of historic Beryllium-10 in ice, which stands therefore as a proxy for cosmic-ray flux, tells us that the cosmic-ray volume coming from the Sun was significantly larger all the way through the last glaciation period, than during the interglacial periods before and after. Only a hibernating Sun can produce these large ratios.
Also note: The extreme cold temperatures plotted above, which define the period of the last Ice Age, coincide precisely with the startup and ending of the very high Beryllium-10 ratios. In addition, the large spikes prior to the interglacial periods, mark the startup of the Primer Fields for the Sun. Once the startup succeeds, the Beryllium ratio quickly diminishes, because then the shell of plasma surrounding the Sun is re-established that attenuates the cosmic-ray flux and enables the high-power Sun.
The plotted Beryllium ratios are extraordinary evidence that ice ages are caused by the Sun going into hibernation. The hibernation ends when the Primer Fields are re-established. Being re-established, the Primer Fields put the Sun back into its high-powered state, with which the interglacial period begins. An in-between state is not possible. The transitions between these two states are radical transitions, rather than slow transitions spanning thousands of years as it is widely believed outside the realm of Plasma Astrophysics.
The reality that we face, which this evidence points to, is that the Sun flips between two radically contrasting power-states; the high-power state that gives it its present surface temperature of 5,800 degrees (Kelvin), and the hibernation state. The hibernation state is a type of universal default state for stars without Primer Fields. The default state corresponds to surface temperature in the 3,000 to 4,000 degrees range.
The vast majority of the stars in our galaxy operate in the 3-4,000 degrees range. One might regard these 'low' temperatures as a type of universal default for stars that have no Primer Fields.
More than 70% of the stars of our galaxy operate in the default range of temperatures. Most of these 'default' stars are the slightly smaller red-dwarf stars. Nevertheless, some giant stars, and super-giant stars, likewise operate in the low-temperature default range, which spans from the mid-K range into the M range. The precise default surface temperature that our Sun will revert to in its hibernation state, cannot be determined.
We only know for certain that the climate-cooling on the Earth during the previous hibernation state of the Sun, was 40 times more massive than the cooling had been that caused the Little Ice Age in the 1600s.
What this means is hard to imagine. History books tell us that the Little Ice Age was a period of harsh climates, of crop failures, mass starvation, and population decline. We have no previously experienced reference available for what a 40-times colder world is like, but which we have to prepare for, and must have ready when the phase shift to the hibernating Sun happens, potentially in the 2050s.
One way to do this, would be to create a new world with indoors agriculture, afloat across the equatorial seas. That's a huge task. Fortunately it can be accomplished with automated industrial production. But are we ready to tackle the enormous task, or even to consider the project?
We have the materials, technologies, and energy resources on hand to do this. But will we do it?
To do the project is not even being considered. And it won't be considered until society stops its mental hibernation. That's where the blocking factor lies by which society is self doomed.
It is time to wake up and break the doom. The Ice Age is already near, as near as the 2050s, and it looms big - far bigger than it is imagined. Get ready and discover what we can do as human beings, and do it.
