Dendrochronological research in the Alps takes place since the 1940s, but until recent years a Holocene tree-ring chronology based on Alpine samples has been missed. The new Eastern-Alpine Conifer Chronology (EACC, from 7109 B.C. to A.D. 2002) discussed here is with its length of more than 9000 years the second longest tree-ring chronology in the world. Based on the EACC, new results were obtained regarding Holocene glacier and tree-line variability in the Alps. These dendrochronological results indicate that on average the early and middle Holocene (until about 4000 years BP) was significantly warmer than the late Holocene. To date, dendroclimatological temperature reconstructions for the Alps cover the last some 1000 years. The reconstructed temperature evolution is in accordance with the known environmental evolution, particularly with the glacier history.
