Abstract
The analysis of many long continental records is done for revelation of the presence or absence of the 400-kyr paleoclimatic periodicity. The loess-soil sediment records of East Europe (Russia, Ukraine) and Asia (West Siberia, Tajikistan, China) are investigated. The data on the Pleistocene environmental changes from the lake Baikal sediment cores, Antarctic (Dome C) ice core and some other data are investigated too. It is shown that: a) the reliable empirical data on the Pleistocene 400-kyr paleoclimatic cyclicity presence are absent; b) the reports about the presence of the 400-kyr periodicity in paleoclimatic continental records are or erroneous, or not related with the eccentricity variations.
