“…The basin experienced discontinuous lacustrine sediment accumulation during the Quaternary (Cavinato and Miccadei, 2000;Giaccio et al, 2012Giaccio et al, , 2013. Its location and the geological, stratigraphic and chronological framework were described in detail in previous studies (Giaccio et al, 2009(Giaccio et al, , 2012(Giaccio et al, , 2013Regattieri et al 2015Regattieri et al , 2016Zanchetta et al, 2017). Briefly, the Sulmona sedimentary succession is divided into three main unconformity-bounded lithostratigraphic units (SUL6, SUL5 and SUL4-3), composed of alluvial, fluvial and lacustrine sediments.…”

Among past interglacial periods, Marine Isotope Stage (MIS) 19 is particularly interesting because its orbital geometry is very similar to that of the present interglacial. Here we present a high-resolution (subcentennial) multiproxy record covering the ca. 790-770 ka interval, i.e. the interglacial MIS 19c and the ensuing glacial inception of MIS 19b, from a lacustrine sediment sequence retrieved from the Sulmona Basin (central Italy). The record has an independent chronology based on radiometric dating of six volcanic ash layers, and the resulting age model has a mean associated uncertainty of ± 2.6 kyr. Variations in sediment geochemistry and mineralogy are interpreted in terms of past hydrological and 2 temperature changes. Several millennial and sub-millennial events of reduced precipitation are well expressed. Comparisons with continental and marine records from the mid-latitude and sub-polar North Atlantic suggest a broad spatial expression for the observed events. Events occurring within the interglacial are not clearly associated with changes in marine proxies in the Iberian Margin, although similarities with the record from the sub-polar North Atlantic can be recognized and tentatively linked to changes in local hydrography having a downstream effect amplified by changes in atmospheric circulation. During the glacial inception, however, changes in the Sulmona record are coherent with changes in North Atlantic records, with drier events likely associated with meltwater-induced intervals of AMOC weakening. An event at ca. 785.6 ka may also reflect oceanic changes caused by freshwater discharges from residual ice-sheets and an outburst flood, similar to the 8.2 ka event in the Holocene.

“…We are aware that there are limitations in this, but it is necessary to understand more details about the 4.2 cal ka BP event. There are other proxies which can give potentially further important information, like lake-level changes (Magny et al, 2007(Magny et al, , 2011, and although discontinuous, isotopes on paleosols (Zanchetta et al, 2000(Zanchetta et al, , 2017 or paleofloods (Zielhofer and Faust, 2008). Although rare, dust records appear of particular relevance in informing about past circulation patterns and hydrological conditions (e.g., Zielhofer et al, 2017b).…”

Abstract. The Mediterranean region and the Levant have returned some of the clearest evidence of a climatically dry period occurring around 4200 years ago. However, some regional evidence are controversial and contradictory, and issues remain regarding timing, progression and regional articulation of this event. In this paper we review the evidence from selected proxies (sea-surface temperature, precipitation and temperature reconstructed from pollen, δ18O on speleothems, and δ18O on lacustrine carbonate) over the Mediterranean basin to infer possible regional climate patterns during the interval between 4.3 and 3.8 cal ka BP. The values and limitations of these proxies are discussed, and their potential for furnishing information on seasonality is also explored. Despite the chronological uncertainties, which are the main limitations for disentangling details of the climatic conditions, the data suggests that winter over the Mediterranean was drier condition, in addition to already dry summers. However, some exceptions to this prevail, – where wetter condition seems to have persisted – suggesting regional heterogeneity in climate patterns. Temperature data, even if sparse, also suggest a cooling anomaly, even if this is not uniform. The most common paradigm to interpret the precipitation regime in the Mediterranean – a North Atlantic Oscillation-like pattern – is not completely satisfactory to interpret the selected data.

“…Therefore, our hypothesis is that Valdocarros II was characterized by a warm and dry climate, similar to the present-day climate of the region. During cold periods, the degree of aridity is known to increase (Roucoux et al, 2006;Tzedakis et al, 2013;Zanchetta et al, 2017). Smaller snail species appear to survive adverse conditions, including cold ones, better than larger species (Ansart and Vernon, 2003).…”
