Radiocarbon datings and paleobotanical information, including some of the pollen data reported in the previous article, are used to revise the periodization of Late Pleistocene sequences in northeast Siberia. They yield four climate‐stratigraphic units that correspond to cooling trends (glacial stages) and warming trends (interglacials). The revised chronology suggests that, despite some distinctive features in the vegetation of northeast Siberia, its Pleistocene evolution conformed to that of other parts of the Northern Hemisphere and was evidently subordinated to climate fluctuations of global scope.
