Abstract

The European Alps is a region very sensitive to Dryas (YD) marked the end of the Palaeolithic painclimatic change (Beniston & Jungo 2002), and it is terso A better insight into the climate evolution of the important to extend the existing climate records as far SE European Alps from the Last Glacial Maximum back in rime as possible to detect any anthropogenic would greatly improve our understanding of Alpine climate signals. At present, there is a large set of history. Rere we present an exceptional c. 17 kyr palaeoclimate and climate data from the CentraI and speleothemr ecord from the southeasternm argin of the Western Alps, but a fragmentary record from the ltalian Alps. Eastern Alps (cf. Davis et al. 2003 and references therein). A stalagmite record from northem ltaly (McDermott et al. 1999) suggested that the CentraI. . Alps had a similar Rolocene climatic evolution as the Samplmg and analytlcal procedures JUTa Mountains and the French Alps. The eastern sec- G h. l tI ' tor of the ltalta..ne oAglrpasp ltes at the boundary between the lca se mg CentraI and Southern European climate regions as The 27-cm-high, candle-shaped, stalagmite SVI was defined by pollen data (Davis et al. 2003) and, there- sampled in Grotta Savi, a cave located at 441 m a.s.l. fore, may show different climate evolution with north of Trieste (4S03ios"N, 13°S3'10"E) (Fig. l). respect to the CentraI and Western Alps.
