Abstract Suggestions that the duration of the Eemian interglacial was about 11,000 yr, based on annually laminated sediment sequences in Germany, have been challenged in favor of a much longer interval. However, biostratigraphic evidence demonstrates why the Eemian sequences at Grande Pile and Ribains cannot be reliably used for alignment with the marine sequence, as applied by Kukla et al. (2002, this issue) to estimate the duration of this interglacial. The long chronology they propose would imply not just coniferous but, for up to 5000 yr, fully temperate forest in central France coexisting with treeless heath and steppe tundra conditions in northwestern Europe, an unlikely climatic and ecological scenario. The proposal that the Eemian Interglacial in western Europe lasted for 17,000 or even 23,000 yr is rejected. A duration of no more than 13,000 yr is preferred, at least for sites north of the Alps and Pyrenees. The duration of temperate conditions in the Mediterranean region is less certain.
