International audience Past analogs for our present interglacial have been sought for better understanding of our present and future climate. Marine Isotope Stage 11 (MIS 11) has long been considered to be a good candidate and has gained increasing attention in recent studies of marine and terrestrial records. In the Chinese loess–paleosol sequences, S4 soil, interpreted as equivalent to MIS 11, yields a very precise terrestrial paleoclimate record of environmental changes that prevailed during this period. In this study, two high-resolution terrestrial mollusc records from the Loess Plateau have been analyzed to characterize climate variability during the periods of MIS 12–10. The changes in environment and climate, indicated by the variations in abundance of land mollusc species, are thus documented. Our mollusc results show that the L5 loess, equivalent of MIS 12, developed under relatively cold and dry conditions. Climate during this period was not as severe as indicated in the marine isotopic records. An episode of warmer and more humid condition occurred at the middle stage of the MIS 12, reflecting a summer monsoon strengthened during the glacial interval. A similar scenario has been observed in the middle part of MIS 10.
