| Summary: | The interglacials of the last 800,000 years are all warm periods comparable to the current interglacial, called the Holocene. However, their intensity, duration, variability and regional expression are different as the result of different astronomical and greenhouse gases forcing. The work presented here focuses on the regional expression of these interglacials in southwestern Europe, and it is based on recent studies using pollen from Iberian margin sedimentary sequences that enables a direct comparison of atmospheric and marine processes. This work highlights the diversity of these interglacials in southwestern Europe in terms of duration as well as vegetation and climatic variability, in particular in southwestern Iberia where changes in precipitation play an important role. This work additionally allows discussing mechanisms involved in glacial inception during orbital analogs of the current interglacial (i.e. marine isotopic stages 19c and 11c). info:eu-repo/semantics/publishedVersion
