An effective climate factor is the Cosmic Ray density
really determines our climate when the 'solar forcing', represented the Milankovitch
Cycles, is too weak to have a major effect as the ice core data indicates? Changes
in cosmic ray density that affects cloud forming and thereby the cooling of the
Earth, have large effects on the climate of the Earth, but these are still only
precursor fringe events in comparison with the hung climate change when the Sun
goes cold and dim, by which the next Ice Age begins.
seen large temperature changes occurring over short timeframes that are neither
statistically predictable, nor mechanistically predictable, but whould be normal
phenomena when the Sun goes inactive and looses 70% of its radiated energy.

14,700 years ago, the Ice Age deep freeze has been interrupted with an enormous
warm spell. In the brief span of only 50 years the climate warmed up by a
whopping 22 degrees. Then, a few decades later, just as abruptly, the climate
reverted back towards Ice Age conditions for another 3000 years until it warmed up
again, just as abruptly, to usher in the current interglacial period. We are
talking about huge changes here that could not possibly have happened if the Sun
had remained a constant factor. Of course we know now that the Sun isn't a
history of climate
Sun's activity decreased in the 1600s so that the sunspots almost disappeared
for 30 years, the Earth went through a little Ice Age (a half a degree
cooling against today, and one and a half degree cooling in respect to the medieval optimum at around 1000 AD,
wich we haven't
even come close to again since that time).
ionize the atmosphere, increasing cloudiness that reflects sunlight back into
space, and the combined effect is reducing the greenhouse effect that is 97% caused by water vapor.
Both factors, acting together, cause global cooling. Without the greenhouse, the Earth would be a
frozen snowball. The cosmic-ray intensity determines both factors. However, by
being an electrically powered system, instead of just fluctuating, the Sun can
also turn off and revert to residual heat, when the electric input density falls
below a minimal threshold. That's what we see happening many times during the
ice ages. It happens every 1470 years, when Sun becomes powered actively for a
brief period and then turns off again.
