In the middle of the last century glaciers of Antarctica and Greenland have been thoroughly investigated. For these purposes the ice cores have been extracted from deep wells. These studies have shown, that for many thousands of years the climate is gradually cooling down. Periodically, once in 100–120 thousand years, the temperature rises sharply by about 10°C. This contradicts the fact, that the Earth's orbit decreases, as it follows from the theory #.2. The climate should become warmer. The climate has really become warmer in recent years, but it is connected, most likely, with the activity of civilization, and not with the orbit change. Gradual and constant cooling of the climate for many millennia is most likely due to a faster "burnout" of the Sun compared to a decrease of orbits.

It is known, that marine sediments are located even on the highest world peaks. From which it follows, that the surface of the "young" Earth has been more even, and it was covered completely or almost completely by the ocean. Initially, the life on Earth originated in the ocean. Mainland has been formed, probably, later. Conditions for life on the land first appeared on the poles. Then, as the climate grew cooler, the life spread from poles to the middle latitudes and then to the equator. Further cooling of the planet led to the formation and proliferation of ice caps at the poles, decrease of the world ocean level and land surface increase. The warm shallow seas were on the Earth in the period of small polar glaciers or their absence. The gradual transition of a significant part of the water from liquid state – into ice and moving to the poles led to bogging and complete drying of ancient seas. If all Antarctica and Greenland glaciers melted, all ancient seas would be in their place.

The expanding Antarctica glacier gradually displaced all living things to the shores. Less and less land, suitable for life, remained on this continent. All its inhabitants had to look for food in the ocean. There was a many-thousand-year process of changing species: land animals turned into marine inhabitants. Only those species of the polar continent inhabitants survived, which had adapted to live in water. Apparently, the mammals appeared in the ocean in this way: whales, dolphins, etc.

The ice age

Studies of ice cores, extracted from the wells of Antarctica and Greenland, allow determining the duration and the end of the last ice age. The graphs shows the results of the study of ice cores at the Russian polar station “Vostok” ^[1]

Graphs of studies of ice cores ^[2]

The top graph shows a change of deuterium content in the ice. This isotopic study was conducted throughout the cylindrical ice cores and provided the most detailed data. Other studies were conducted in interval 2.5 m and were more approximate. Reduction of deuterium content in the ice corresponds to a temperature decrease. The graph shows, that between the temperature maximum about 130 thousand years ago and its minimum about 12 thousand years ago, there was a steady temperature decrease, which sometimes was alternated with short warming.

On the Dome Concord 75° sl a glacier age was determined as 890 thousand years old, by the ice cores with the total length of 3270 m. Although the researchers believe this data was very approximate. The speed of cooling can be determined from the graphs. During 120 thousand years the temperature decreased by ~ 10°C. The last ice age ended 10-12 thousand years ago. By the end of the ice age the Earth has been so cool so, that the glaciers occupied, presumably, the fourth part of the continents. Glaciers themselves contribute to their spreading, by reflecting the sunlight and cooling the surrounding air.

In the Ice age a map of the Earth was somewhat different. The global sea level was lower, because a significant portion of the water was in the ice. The continents had a wider coastal zone, but a considerable part of them was under the ice and was not suitable for life. There were some islands in the Ice Age, which we can see now on the maps as shallow waters.

In the Ice Age lot of mammoths and other animals lived in cold climatic zones. They lived in the large parts of North America and Euro-Asia and were well adapted to the cold climate.

Ice Age ended, when climate warmed suddenly.

Great flood

From times of the Old Testament, people heard about the Great flood, however, very few people trusted this legend, because it was absolutely not clear, where such mass of water has come from and where it has disappeared. It is logical to assume, that the Great flood was the end of the Ice Age.

When it was?

1. The graphs of Antarctic ice cores study show, that the abrupt warming occurred about 12 thousand years ago (see the upper graph).

About a same time, a global sea level rose by ~70 m, to the current level of 0 m.

2. Around the same period, as some researchers believe, the mass death of mammoths occurred.

3. Probably, the flood has caused the death of the previous civilization. Plato, who lived around 400 BC, states, that Atlantis perished 9.5 thousand years ago. If we add our 2000 years, then 9.5 + 0.4 + 2 = 11.9 thousand years ago.

4. Edgar Cayce, in the reading 5750-1 dated November 12, 1933, stated: "From time as counted in the present we would turn back to 10,600 years before the Prince of Peace came into the land of promise, and find a civilization being disturbed by corruption from within to such measures that the elements join in bringing devastation to a stiffnecked and adulterous people."^[3] 10,600 years before Christ 1933 will be 12.533, rounded to 12.5 thousand years.

These four independent coincidences give reasons to believe, that date is approximately right. Cayce indicates the fall of morality as the cause. However, there must be a physical mechanism of the past global catastrophe.

Various versions can be assumed as the explanation of abrupt climate warming. The most probable reason of the climate warming may be periodic passages of a large celestial body near the Earth, for example, a long-periodic comet. Arising between them a gravity force can be the cause of displacement of the Earth concerning poles and fluctuation of axis. As a consequence, the cold zones could be shifted to warmer latitudes and continental glaciers have melted. Glaciers are "refrigerators" of the Earth. Reduction of glaciers has given way to the global climate warming on the planet.
