“…These results fit well with the relatively high lake levels at Ledro (Fig. 6), with the speleothem results from Corchia and Renella (Zanchetta et al, 2007b;Zhornyak et al, 2011), and with southern Alpine speleothems (Spötl et al, 2010). Southern and eastern Alpine speleothem records appear to register a humid period that is contemporaneous with the wettest phase identified at Corchia (i.e.…”

“…4). High winter precipitation is consistent with the increase in flood activity due to increased storminess in the region suggested by Zhornyak et al (2011), and is confirmed by a significant increase in winter precipitation between ca. 9500 and 7000 cal yr BP in the northern Aegean Sea (Kotthoff et al, 2008.…”

“…8900 and 7300 cal yr BP has been interpreted from speleothems recovered from Corchia Cave in the Apuan Alps (Zanchetta et al, 2007b) and from ca. 8200 to 7100 cal yr BP from Renella Cave, close to Corchia Cave (Zhornyak et al, 2011). The Renella record suggests that during the early to midHolocene, the region experienced very wet conditions associated to a substantial increase in flood activity (Zhornyak et al, 2011).…”

Lake-level records from Italy suggest that patterns of precipitation in the central Mediterranean during the Holocene were divided between the north and south, but a scarcity of reliable palaeoclimatic records in the north and central-southern Mediterranean means new evidence is needed to validate this hypothesis. We provide robust quantitative estimates of Holocene climate in the Mediterranean region using four high-resolution pollen records from northern (Lakes Ledro and Accesa) and southern (Lakes Trifoglietti and Pergusa) Italy. Multiple methods are used to provide an improved assessment of the palaeoclimatic reconstruction uncertainty. The multi-method approach uses the pollenbased weighted averaging, weighted-average partial leastsquares regression, modern analogue technique, and the nonmetric multidimensional scaling/generalized additive model methods. We use independent lake-level data to validate the precipitation reconstructions. Our results support a climatic partition between northern and southern Italy during the Holocene, confirming the hypothesis of opposing mid-Holocene summer precipitation regimes in the Mediterranean. The northern sites (Ledro, Accesa) are characterized by minima for summer precipitation and lake levels during the early to midHolocene, while the southern sites (Trifoglietti, Pergusa) are marked by maxima for precipitation and lake levels at the same time. Both pollen-inferred precipitation and lake levels indicate the opposite pattern during the late Holocene, a maximum in northern Italy and a minimum in southern Italy/Sicily. Summer temperatures show the same partitioning, with warm conditions in northern Italy and cool conditions in Sicily during the early/mid-Holocene, and a reversal during the late Holocene. Comparison with marine cores from the Aegean Sea suggests that climate trends and gradients observed in Italy show strong similarities with those recognized from the Aegean Sea, and more generally speaking in the eastern Mediterranean

Pollen-based quantitative estimates of seasonal precipitation from Lake Pergusa and lake-level data from\ud \ud Lake Preola in Sicily (southern Italy) allow three successive periods to be distinguished within the Holocene: an early\ud \ud Holocene period before ca. 9800 cal a BP with rather dry climate conditions in winter and summer, a mid-Holocene\ud \ud period between ca. 9800 and 4500 cal a BPwithmaximumwinter and summerwetness, and a lateHolocene period after\ud \ud 4500 cal a BP with declining winter and summer wetness. This evolution observed in the south-central Mediterranean\ud \ud shows strong similarities to that recognized in the eastern Mediterranean. But, it contrasts with that reconstructed in\ud \ud north-central Italy, where the mid-Holocene appears to be characterized by a winter (summer) precipitation maximum\ud \ud (minimum), while the late Holocene coincided with a decrease (increase) in winter (summer) precipitation. Maximum\ud \ud precipitation at ca. 10 000–4500 cal a BP may have resulted from (i) increased local convection in response to a\ud \ud Holocene insolation maximum at 10 000 cal a BP and then (ii) the gradual weakening of the Hadley cell activity, which\ud \ud allowed the winter rainy westerlies to reach the Mediterranean area more frequently. After 4500 cal a BP, changes in\ud \ud precipitation seasonality may reflect non-linear responses to orbitally driven insolation decrease in addition to seasonal\ud \ud and inter-hemispheric changes of insolatio
