The author educated in history and specialized in design engineering happened to start working with the themes of ancient glaciation, when he studied migration of the ethnic groups in the process of thawing the Eurasian glacier during the Golocene in context of the common work on Slavonic-Russian ethnonimics.

Therefore, we consider the proposed views to be not more than a hypothesis. Our method of study, our weapon is using the visual Cainozoic glacial fluctuation graphs displayed to time scale line according to initial data of the eminent specialists in glaciology and founding the theory without contradictions, if pos-sible, which explains regularity of ancient glaciations reflected on such graphs. The data of the academician Moskvitin (Anthropogene) and the American glaciologist Andrews (Pliocene) was assumed as a basis of the graphs. The dates are for reference and in need of revision.

The 1st and the 2nd graphs of the table 1 display changing of the Cainozoic glacial periods to the shape of rectangle, the 3rd and the 4th graphs the same fluctuations to the shape of sinusoids. There are 8 periods in all. The graphs show the Pliocene glacial period is very large, glaciation and inter-glaciation last for about 1,6 million years each. In the early Pleistocene glaciation and interglaciation go on for about 500 thousand years each, then they cut down to 200 thousand years, later on in the middle Pleistocene the train of glaciations and interglaciations passes being 100 thousand years each, and in the late Pleistocene the half-periods approximately halve each time, cutting gradually down to 22-18 thousand years.
Besides, the traditional question «why do glaciation change regularly for interglaciation» we can ask now why do the glacial fluctuation periods about 80 times reduce their duration in the Cainozoy, what is the reason for such glacial process?
According to our conception the reason for changing the Cainozoic glacial phases consists in sharp change of the oceanic currents, and first of all the Gulf Stream and the Kuroshio, when a glacier reaches its critical maximum (in case glaciation changes for interglaciation) or its critical minimum mass(in case interglaciation changes for a new glaciation). Crust buckling up and down in the Bering region and the same out of phase (and out of synchronism) in the near-greenland space play the lea-ding part in that process. As we think very slow crust buckling up and the same slow buckling down in those regions can be accelerated by the catastrophic faults of the lithosphere seams in the regions of the North-Atlantic rift and its branches or the Aleutian-Kmchatka trenches in conformity with the phase of glacial process. Then the edges of lithosphere slabs are buckling sharply up or down in one or the other of the mentioned regions having exceeded shearing stress from the vertical forces the corres-ponding resistance limit for the connecting material which binds the edges of lithosphere seam.
Our mechanism of glacial fluctuation has something in common with the Layel-Dan hypothesis of the XIX century, who saw the reason of changing the glacial and the interglacial phases in change of the Gulf Stream direction as well, but we consider the vertical land motions from the point of view of a new mobilism theory — theory of lithosphere slabs being a remarkable discovery in geology of the second half of the XX century which naturally was unknown for Layel and Dan.
Thus, we see the reason for coming every new Cainizoic glaciation in thawing the Greenland ice-shield below the minimum critical mark. As a result of ice thawing the crust seek to straighten its buckling down existed before, to rise up. Stress will exceed the resistance limit in the lithosphere seam of the North-Atlantic rift region in the certain phase, a catastrophic fault will open and the near-greenland crust region will rush sharply up, this way decreasing width of the Denmark, the Davis and the other straits of the Canadian Arctic Islands. The surface and the deep currents existing there will be cut off, water outflow from the Arctic to the Atlantic Ocean will reduce sharply. Backwater will be formed in the Arctic Ocean, and the dynamic wave can arise in the Greenland Sea being a strong stream which will search where to go out and rush into the North Sea along the line of least resistance and pass the La Manche towards the Atlantic Ocean. Naturally, those stream will gush so as to cross the Gulf Stream, turn it in the latitudinal direction and drive it off to the south for a long thousands of years. Having the lithosphere seam fault in the dynamics, crust pressure in the mantle magmatic stratum will change in this region, it will decrease sharply and a sad fate of Atlantida can overtake the low-lying regions of Britain, Ireland, Holland and a number of the other low-lying lands of Western Europe. The same occurs in every glacial cycle. Atlantida (Madeyrida perhaps united with Canareida by land) renews approximately in the middle of each glaciation when the level of the World Ocean decreases considerably, and, that’s more important, the north-western part of the Eurasian slab goes jerkily down into the ocean deeper and deeper under heaviness of glacier with the periodic lithosphere seam faults as well. And then the catastrophe goes back, having thawed mainland ice approximately in the 1st third of every interglaciation: South Britain, Netherlands etc. rise jerkily from the ocean, and Atlantida and the part of the Mediterranean region come down into the oceanic gulf with rumble and crash of earthquakes, with the flashes of volcanic eruptions. Certainly, at the same time land buckles slowly and smoothly up or down having slacked or increased its glacial load.
Let’s return to the moment of the beginning of a new glaciation. When the Gulf Stream goes away from the Arctic Ocean (AO) from the shores of the North America in the form of arc which doesn’t reach the Faeroes to the shores of Spain and further to the Tropical Atlantics, the water level in the AO will begin to fall down and the Kuroshio will rush into it with high speed through the Bering Strait raising the water level in it up to the level of the World Ocean. The climate of Antarctica with the frosts impossible now will set already during the first winter in North Atlantics deprived of heat of the Gulf Stream, the continuous severe snowstorms and blizzards, the Greenland, the North, the Norwegian, the Baltic and the Barents seas unfreezing now will freeze at once. His Magesty New Glacial Period will set to the north-west of Eurasia and in the North America for a long thousands of years (for 12-15 thousand years according to our estimation).
The damp subtropics will come to the North-East Asia and Alaska, having set total supremacy of the warm Kuroshio in the north part of the Pacific Ocean (PO) and in the east part of the AO (inclu-ding in the sea of Okhotsk, the Bering, the Chukchi, the East Syberian, the Laptev and the Beaufort seas). At the same time, the glaciers thick enough can be formed on the mountains of Chukotka, Alaska, Yakutia and Kamchatka owing to the low level cryosphere typical for the near-polar regions and increasing humidity of air, but there will be very warm on the valleys and the lowlands. We pro-pose to consider the present climatic condition of the North-East Asia including Yakutia as the peculiar glacial period changing naturally for the mild, but also peculiar interglaciation being in the opposite phase to the West-Eurasian and the North-American glacial period. Its peculiarity consists in the fact that it’s very cold during the cold period but the glaciers aren’t available owing to dryness and very warm in the mild period, but the mountain glaciers grow on because of intense increase of humidity.
Having turned to the south, the Gulf Stream will do away with or push aside the cold Canary Current and bring abundant precipitation to Spain and the Sahara. There will set the climate called pluvial, i.e. a rainy period. Though, it’s not very stable and simple in the Sahara as the data of the field climatology shows.
In our time the phases of the glacial period will change back in 12-15 thousand years as mentioned. The West-Eurasian-North-American glacier grown on up to enormous dimensions will build up huge pressure in the crust and the mantle which will influence on all the crust through astenosphere by the Pascal’s law including the Bering region. Crust buckling down to the west of Eurasia and in the North America will have as natural consequence its buckling up in the Bering region. The level of the World Ocean will go down at the end of the glacial period, and dryness of atmosphere will increase. The mountain glaciers of Chukotka and Alaska which before the moment prevent by its heaviness from buckling up and blocking the Bering Strait will begin apparently to thaw at the final stage of dvelop-ment of the process. The above will lead to the fact that the strait bed will begin to rise slowly generating tangential stress in the lithosphere seam of the Aleutian Trench. Having exceeded the resistance limit of seam, it will give a fault in the most strained section, Beringia will rush sharply up, and the Bering Strait will stop existing. It will renew, having thawed the Great West Glacier, but till then the route for the Kuroshio to the AO will be closed, the water level will begin falling in it, and the Gulf Stream will be «forced» to rush into the AO raising its level. A new interglaciation will begin. Some thousands of years shelf and sea ice will thaw, then mainland ice of the North-West Eurasia and the North America will thaw thousands of years as well. The Greenland glacial shield will thaw the last down to a new minimum critical mass. According to our opinion the level of minimum critical mass determines strength of the lithosphere seam in the north section of the Central Atlantic Rift. It will become gradually warm again, having reformed ordinarily the oceanic currents in the North-West Eurasia and the North America, the arid climate of the greatest desert in the world will set again in the Sahara, the pole of cold will return anew to Yakutia, and Kolyma and Chukotka stop being the health resorts.
The proposed conception possesses certain logical harmony, can be corroborated and proved scientifically using geology, paleoclimatology, paleontology, paleobotany and paleozoology. If you look attentively at the map of the Bering region given in the book «Winters of Our Planet» M. Mir, 1982, fig.150, p.252 (trans. from Engl.), you’ll see that ice by the shores of Chukotka, the Eastern Siberia to the Taimyr Peninsula and also the north Alaska isn’t available at all during maximum glaciation of the last glacial period. All the north Europe is under ice as well as all the north-west Asia, all the northern part of the North America, the greatest part of the area of water of the AO and the northern part of the Atlantic Ocean along the line of Labrador, Greenland, Iceland, the Faeroes, Ireland, Britain. At the same time ice isn’t available in the AO to the east of the Taimyr Peninsula along Chukotka and Alaska right up to the Victoria Island to the north of Canada and almost up to the very North Pole. Why? You see in our time at the end of Golocene the heaviest ice is just in those parts even during summertime. We have an answer: warm water of Kuroshio which then being a strong stream came in the AO through the Bering Strait and heated the AO in the Bering region during the Ostashovsky glaciation as well as the other ones. And the situation in the North Atlantics shows clearly that at the same time the Gulf Stream turned to the south forming the great arc and didn’t reach Greenland, Iceland and the Faeroes. Only the hopelessly blind people can’t see the fact. Analysis of the map (fig.150) shows that the hypothesis of autofluctuating Cainozoic glacial process stated in the given work has a reliable foundation, and the hypotheses orientating toward changing of albedo, the hotbed effect, the sun and the space cycles etc. have auxiliary importance. They play their part, but just their part. Any changes of the oceanic currents and first of all the Gulf Stream and the Kuroshio proceeding from buckling down of terrestrial surface and the faults of the lithosphere seams by turns in the Bering and the Greenland regions play first fiddle in the Great Cainozoic Glaciations. The direct evidences that such faults and sharp buckling up and down of the parts of land aren’t a fiction but a reality which can be checked, aren’t available. The scale of time is colossal, geological. And those rifts and trenches are deeply. The indirect evidence is some information of Platon about Atlantida, about the circumstances because of which that mysterious insular country is lost. We hold fast on Atlantida and think that time and onward development of science will confirm our considerations.
