<!--!introduction!--> The mechanisms leading to the emergence of strong 100,000-year ice age cycles at the end of the Middle Pleistocene Transition (MPT), ~670-800 ka, encompassing Marine Isotope Stage (MIS) 19, 18 and 17, are still not fully understood. This period is associated with anomalously warm North Atlantic sea surface temperatures enhancing moisture production and transport to northern hemisphere ice-sheets. However, the most relevant processes explaining the progressive ice accumulation during the end of MPT remain unclear yet, partly due to the poor knowledge of the Eurasian environments and atmospheric climate. New marine-terrestrial climatic records from the IODP Site U1385 (south-west Iberian margin) and their comparison with loess records from the Chinese Plateau reveal a nearly synchronous, long-term warming and wetting trend in the two subtropical regions from MIS 19 to 17. Mediterranean forest cover and winter precipitation were stronger during the MIS 18 glacial compared to the MIS ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ...
