| Abstract: | The three problems composing the astronomical theory of paleoclimate have been solved in a new way. Two of them (changes in the orbital motion of the Earth and its insolation) have confirmed the results of previous research. In the third problem (a change in the rotational motion of the Earth), the obtained oscillations of the Earth’s rotation axis have an amplitude seven–eight times higher than the earlier estimated one. They lead to changes in insolation, which explain the paleoclimatic fluctuation. The changes in insolation and its structure for 200 kyr are considered. It is shown that the Late Pleistocene key events in West Siberia, for example, the last glaciations and warming between them, coincide with the extremes of insolation. The insolation periods of paleoclimatic changes and their characteristics are given. |
