Geochronological Ice Ages, periods, eras
Earlier, we considered the biblical and astrophysical End of the World, which did not take place in 1492 and is assumed to be 5.5 billion years later, respectively.
The trouble, however, today is that a disastrous situation for civilization can actually ripen very soon for a completely different reason, that is, long before the astrophysical End of the World. This can be caused by natural evolution and the struggle of the species of Darwinian natural selection for existence.
This is evidenced by the WHO forecast of the possibility of a new virulent virus emerging by 2050 with a mortality rate of up to 35%.
Planet Earth has three main models of the temperature existence of its surface in geological history:
1. The "greenhouse" option, when tropical temperatures extend to both poles and there are no ice sheets at all;
2. The variant of a "refrigerator", when there is some permanent ice, although its length and thickness on the Earth's surface varies greatly;
3. A variant of the "snowball". Snowball Earth, in which the entire surface of the planet is completely frozen and presented as endless blocks of ice and snow, many kilometers thick.
Snowball Earth Model
Specifically, now the Earth is in the "refrigerator" version: its poles are covered with an ice shell, which includes the sea ice of the Arctic and the Antarctic ice sheet.
Thus, there is a so-called "temperature swing" or "temperature pendulum": the Earth's surface is completely covered with ice and snow, then completely free of them, constantly moving from one extreme to another through the state of the "refrigerator".
This process is regulated between three variants of the Earth's surface temperature existence by Milankovitch's long cosmic astrophysical cycles, first described by the author in 1941 (Milankovitch, Milutin. 1941. Canon of Insolation and the Ice Age Problem. Belgrade: Zavod za Udz̆benike i Nastavna Sredstva. ISBN 978- 86-17-06619-0 .; Astronomical Theory of Climate Change).

This temperature pendulum swings very slowly. Geologists distinguish the following four great Ice Ages in the geochronological history of the Earth:
- Early Proterozoic - 2.5 ÷ 2.2 billion years BC;
- Late Proterozoic - 900 ÷ 590 million years BC;
- Paleozoic - 380 ÷ 200 million years BC;
- Cenozoic - 65 million years BC - Until now.
Each such large Ice Age, in turn, is divided into smaller Ice and Interglacial Ages (including Small Ice Ages), and each such Period is divided into even smaller geological Ages.
Temperature cycles have a direct effect on the flora and fauna that live on the Earth's surface. This mechanism of climate-temperature influence has been named by Darwin's "natural selection" after Charles Darwin, the scientist who discovered it.
The Milankovitch Cosmic Cycle is the cause of the periodic occurrence of Ice Age, Periods and Epochs, on Earth. In turn, this means that natural Darwinian selection takes place on the basis of Milutin Milankovich's climatic law. In each such Ice Age, Period and Epoch, almost all flora and fauna on the surface of the Earth always perished.
The past geochronological history of the Earth can be found by studying an ice core, for example, Vostok station in Antarctica:
