Lacustrine sediments are ideal archives for deciphering terrestrial climatic changes. Since sediment records from lakes often reflect a mixture of global, regional and local signals, it is necessary to combine multiproxy data sets from lakes in different regions to exhibit the larger-scale climatic evolution including the recognition of regional differences. Such an approach is presented in this paper for the reconstruction of Holocene climate in Europe. Difficulties arise from correlation problems and dating uncertainties as well as from the fact that lake records from key regions like Siberia are rare and that not all sediment profiles cover the whole time window. A basic requirement for climate reconstruction from lake sediments is a reliable time scale in calendar years derived from varve counting. Therefore, the network of lake sediment archives presented here is grouped around two of the best dated records, Lake Gosciaz, Poland, and Holzmaar/Meerfelder Maar in the Eifel, Germany. Tie-point for these records is the Late Glacial/Holocene boundary with an almost perfect agreement in dating. The main characteristic of the Holocene climate evolution, a temperature maximum during the Atlanticum, is well documented in both records and most of the other regions described. In contrast, the warmest part of the Holocene in Siberia appears to be slightly earlier during the Boreal. Despite a general trend of climatic deterioration interpreted from all records, changing patterns of maritime influences and continentality have been detected besides an increasing influence of man during the last ~3000 years.
