“…In a sediment core from the Western Mediterranean Sea, nalkane based temperature estimates showed a maximum at about 125 ka (Kandiano et al, 2014), suggesting that the humid period was accompanied with a warm event in this area. In the C and O isotope data from a stalagmite from Southern France, Couchoud et al (2009) detected fluctuations of warm/wet and cold/dry periods, with increased rainfall amount at 127.9-126.3, 125.3-123.8 and 123.1-122.4 ka, as shown also in Fig. 11.…”

“…Fewer than a dozen speleothem C and O isotope records represent at least a part of the LIG in Europe (Linge et al, 2001;Holzkämper et al, 2004;Drysdale et al, 2005;Muñoz-García et al, 2007;Meyer et al, 2008;Couchoud et al 2009;Boch et al, 2011;Genty et al, 2013;Regattieri et al, 2014;Moseley et al, 2015), and only a few of them cover more than 10 ka including peak interglacial conditions as well as the glacial inception (Drysdale et al, 2005;Meyer et al, 2008;Drysdale et al, 2009;Moseley et al, 2015;Vansteenberge et al, 2016).

“…As discussed above, low δ 13 C values indicate increased humidity, and the same (with relative increase of winter precipitation) is assumed for the low δD values (see above). Regional humidity proxies are provided for the period by the carbon isotope compositions of the Han-9 stalagmite (Hansur-Lesse Cave, Vansteenberge et al, 2016) and the BDinf stalagmite (Bourgeois-Delaunay Cave, Couchoud et al, 2009) that can serve as independent test records.

“…Compared to earlier periods, stalagmites from the last interglacial (LIG) are rather frequent and can be studied in sufficient numbers (Govin et al, 2015). Stable C and O isotope records, for instance, from European caves' carbonate deposits are available from Belgium (Vansteenberge et al, 2016), the Alps (Austria; Meyer et al 2008, Boch et al, 2011Moseley et al 2015), the Massif Central (France; Couchoud et al 2009), and the Apuane Alps (Italy; Drysdale et al, 2005;2007). These records have been dated by the U-Th series dating method providing numerical ages, making them valuable for paleoclimate studies on the LIG, although their geochemical compositions have not been evaluated in detail as yet (Govin et al, 2015).…”

Highlights Stable isotope compositions of a last interglacial (LIG) stalagmite, Central Europe  A sequence of climate change events during the LIG for European speleothems  Hydrogen isotope data of inclusion water reveal a major event at about 125 ± 2 ka  Temperature and winter precipitation changes around the Mediterranean at 125 ± 2 ka ABSTRACT Studies on the last interglacial (LIG) can provide information on how our environment behaved in a period of slightly higher global temperatures at about 125 ± 4 ka, even if it is not the best analogue for the Holocene. The available LIG climate proxy records are usually better preserved and can be studied at a higher resolution than those of the preceding interglacials, allowing detailed comparisons. This paper presents complex stable hydrogen, carbon and oxygen isotope records obtained for carbonate (δ 13 Baradla data indicate enhanced aridity and seasonality for a part of GS26, with the relative dominance of summer precipitation and Mediterranean moisture contribution. Following the GS26 event, the effect of long-term global cooling becomes dominant in the Baradla isotope records and leads to glacial inception at about 109 ka.

“…The speleothem records covering the Eemian and early Weichselian in Europe have provided detailed paleoclimate reconstructions . Several speleothem stable isotope proxies from Europe record optimum climatic conditions during the Eemian (Meyer et al, 2008;Couchoud et al, 2009) and D/O climate events during the early Weichselian (Bar-Matthews et al, 1999;Drysdale et al, 2007;Boch et al, 2011). Yet so far, all records covering that time period are located in southern Europe (Italy, southern France, Levant) or the Alps.…”

Paleoclimate in continental northwestern Europe during the Eemian and early Weichselian (125–97 ka): insights from a Belgian speleothem

Abstract. The last interglacial serves as an excellent time interval for studying climate dynamics during past warm periods. Speleothems have been successfully used for reconstructing the paleoclimate of last interglacial continental Europe. However, all previously investigated speleothems are restricted to southern Europe or the Alps, leaving large parts of northwestern Europe undocumented. To better understand regional climate changes over the past, a larger spatial coverage of European last interglacial continental records is essential, and speleothems, because of their ability to obtain excellent chronologies, can provide a major contribution. Here, we present new, high-resolution data from a stalagmite (Han-9) obtained from the Han-sur-Lesse Cave in Belgium. Han-9 formed between 125.3 and ∼ 97 ka, with interruptions of growth occurring at 117.3-112.9 and 106.6-103.6 ka. The speleothem was investigated for its growth, morphology and stable isotope (δ 13 C and δ 18 O) composition. The speleothem started growing relatively late within the last interglacial, at 125.3 ka, as other European continental archives suggest that Eemian optimum conditions were already present during that time. It appears that the initiation of Han-9 growth is caused by an increase in moisture availability, linked to wetter conditions around 125.3 ka. The δ 13 C and δ 18 O proxies indicate a period of relatively stable conditions after 125.3 ka; however, at 120 ka the speleothem δ 18 O registered the first signs of regionally changing climate conditions, being a modification of ocean source δ 18 O linked to an increase in ice volume towards the Marine Isotope Stage (MIS) 5e-5d transition. At 117.5 ka, drastic vegetation changes are recorded by Han-9 δ 13 C immediately followed by a cessation of speleothem growth at 117.3 ka, suggesting a transition to significantly dryer conditions. The Han-9 record covering the early Weichselian displays larger amplitudes in both isotope proxies and changes in stalagmite morphology, evidencing increased variability compared to the Eemian. Stadials that appear to be analogous to those in Greenland are recognized in Han-9, and the chronology is consistent with other European (speleothem) records. Greenland Stadial 25 is reflected as a cold/dry period within Han-9 stable isotope proxies, and the second interruption in speleothem growth occurs simultaneously with Greenland Stadial 24.

Offset timing of climate oscillations during the last two glacial‐interglacial transitions connected with large‐scale freshwater perturbation

Th-dated speleothem timescale to ODP976 suggests glacial conditions in the Northeast Atlantic region were terminated abruptly and interglacial warmth was reached in less than a millennium. The early-MIS5e cooling and freshening at ODP976 coincided with similar changes at North Atlantic sites suggesting this was a basin-wide event. By analogy with T1, we argue that this was a YD-type event that was shifted into the early stages of the last interglacial period. This scenario is consistent with evidence from northern North Atlantic and Nordic Sea sites that the continuing disintegration of the large Saalian Stage (MIS6) ice sheet in Eurasia delayed the advection of warm North Atlantic waters and full-strength convective overturn until later stages of MIS5e.
