Only the ice is eternal. The universe is in constant struggle between the powers of ice and fire. On Earth the fires sometimes go out, and the eternal ice wins again. 
Once upon a time, there was a supergiant star in the direction of the constellation Columba. A smaller star, dead, water-soaked to the core, fell into it. It was heated up, vaporizing the water, and causing a great explosion. The fragments of this smaller star were spewed out of the supergiant into interstellar space. The water condensed out into ice, forming giant ice blocks. A ring of this ice formed, as well as a small number of solar systems. This ring is known to us all as the Milky Way. 
This frigid cosmology is that of Hans Horbiger (1860 – 1931, image at top). It is known as Wel Welteislehre, the doctrine of Eternal Ice. In 1952, a German author, Elmar Brugg, explained the theory of eternal ice as establishing the connection between cosmic events and the cataclysms attributed to climate disturbances. Around this same time, a survey indicated Horbiger had at least one million followers. Immanuel Velikovsky himself is said to have been one of the believers in the theory of Eternal Ice. 
Cosmic events connected to the cataclysms of climate disturbances. The Sun enters a period of solar hibernation. The ice wins again. Unusual cold has hung over east central Illinois this past year. The local newspaper reported on December 2, 2014 that the Champaign-Urbana, Illinois region is on track to record one of its coldest years ever.  The winter of 2013-2014 was unremitting: There would be sub-zero cold, a slight warming followed by heavy snow, and then a return to sub-zero cold. There was scarcely any break from this pattern, such as a few sunny days with temperatures in the 30s. Then came a version of The Summer That Never Was. (In 1816, a solar hibernation, the Dalton Minimum, led to severe summer climate abnormalities and a dramatic drop in temperatures. ) Except for briefly in May 2014, where was summer here? Where were those hot days? They never came. And now, locally, the month of November 2014 has come in as “the fourth-coldest November in local weather history.” 
In this small cosmopolitan city, some are even secretly praying for just a little bit of that “global warming” they have heard so much about!
But instead of granting their sinful wish for just a tad more “global warming”, Mother Nature is predicted by The Farmer’s Almanac to be sending yet more record cold. The eastern half to two-thirds of the United States will experience “another cold one” this winter, forecasts The Farmer’s Almanac, which accurately forecast the cold winter of 2013-2014. “As solar activity continues to decline from a low peak, we expect temperatures in much of the nation to be below normal this winter…” 
The number of sunspots visible on the sun waxes and wanes with an approximate 11-year cycle.  And it just so happens that Jupiter orbits around the Sun once every 11.86 years.  Putting the two together, Hans Horbiger theorized that the eleven-year sunspot cycle is caused by Jupiter’s approximately eleven-year orbit of the Sun: the “sunspots” are caused by blocks of ice falling from Jupiter into the Sun. As Jupiter gets nearer to the Sun, there is an increase in falling iceblocks and hence there are more “sunspots.” 
There is a constant battle in outer space between ice and fire. Sooner or later the ice wins. Glacial periods on Earth are the norm, rather than the exception. And these glacial periods arrive relatively fast, when they come. Witness, for example, the Mastodons, whose remains are sometimes found intact but frozen. They disappeared from North America as part of a mass extinction presumed to have been due to a result of rapid climate change in North America. “Despite popular belief that North American mastodons were hunted to extinction by Ice Age humans, a new Canadian-led study is claiming that the prehistoric beasts simply froze to death.”  People laughed when nothing much seemed to happen at the dreaded end of the Mayan Long Count calendar in December 2012. But not long thereafter it began to be noticed that the winters had turned extremely cold.
