“…The coherency of the Bond et al (2001) marine signal with complementary records from marine sediments (Christl et al, 2003;St-Onge et al, 2003;Poore et al, 2004;Jiang et al, 2005), lacustrine settings (Björck et al, 1991;Magny, 1993;Verschuren et al, 2000;Snowball and Sandgren, 2002;Hu et al, 2003;Lim et al, 2005), speleothems (Neff et al, 2001;Niggemann et al, 2003;Fleitmann et al, 2003;Mangini et al, 2005;Wang et al, 2005), polar ice sheets (Stuiver et al, 1997;Laj et al, 2000), Alaskan glaciers (Wiles et al, 2004), bogs (Chambers et al, 1999;Blaauw et al, 2004;Xu et al, 2006), intensity of monsoonal or wet/dry cycles (Hodell et al, 2001;Wang et al, 2001;Cruz et al, 2005;Gupta et al, 2005) and pollen records (Viau et al, 2002;Willard et al, 2005), suggests that we are indeed dealing with a global record of climate. The ultimate driver was likely the variable solar activity, the more so that the CO 2 levels during this entire time span were relatively flat (Figure 55), at the "pre-industrial" levels of ≈270 ±10 ppm (Indermühle et al, 1999).…”

Abstract. In recent years the variability of the cosmic ray flux has become one of the main issues interpreting cosmogenic elements and especially their connection with climate. In this review, an interdisciplinary team of scientists brings together our knowledge of the evolution and modulation of the cosmic ray flux from its origin in the Milky Way, during its propagation through the heliosphere, up to its interaction with the Earth's magnetosphere, resulting, finally, in the production of cosmogenic isotopes in the Earth' atmosphere. The interpretation of the cosmogenic isotopes and the cosmic ray -cloud connection are also intensively discussed. Finally, we discuss some open questions.

“…Later Magny (1993) detected a correspondence between atmospheric 14 C variations and lake-level changes. Short-term 14 C variations may result from variations in solar radiation which may induce climatic changes (van Geel et al 1996;Beer et al 1999;Björk et al 2001;Bond et al 2001;Blaauw et al 2004). However, the relationship between climate and solar activity is not linear and is still a matter of discussion (Muscheler et al 2004;Ponyavin 2004;Solanki et al 2004).…”

Lake-sediment records were used to reconstruct human impact on the landscape around Lago Lucone (45 • 33 N, 10 • 29 E, 249 m a.s.l.), a former lake in the western amphitheatre system of the Lago di Garda. Presence of prehistoric human populations is attested by pile-dwelling settlements from the Early-Middle Bronze Age, with one settlement at a distance of only 100 m from the coring site. Pollen, plant-macrofossil and microscopic charcoal analyses were applied to a 250 cm sediment core with four dates providing the time control. A mixed oak forest that was important during the Early-Middle Holocene was cleared and replaced by open vegetation during the Bronze Age (∼2000-1100 b.c.) when open lands were estimated to have covered more than 60% of the total relevant pollen-source area. During a phase of high human impact, independent climatic proxies suggest warm and dry climatic conditions. Later, ca. 1100 b.c., palaeobotanical evidence indicates a sharp decrease in human pressure in the Lago Lucone area. The comparison with other sedimentary palaeocultural records shows that the period 1300-1100 b.c. was characterised by general declines of agricultural activities both south and north of the Alps. These declines have been previously attributed to a change towards wetter and colder climatic conditions in and around the Alps. However, the decline in human impact around Lago Lucone cannot be exclusively attributed to climatic variation. Therefore other V. Valsecchi ( ) · W. Tinner · W. Finsinger · B. Ammann

“…For example, the hydrological conditions strongly control the occurrence and relative abundance of different testate amoeba species on peatlands (Charman et al, 2000). By analysing testate amoebae community changes over a peat profile, it is possible to quantitatively and qualitatively reconstruct changing mire surface wetness (Booth et al, 2004;Lamentowicz et al, 2008;Sillasoo et al, 2007).…”

Mid- and late Holocene dust deposition in western Europe: the Misten peat bog (Hautes Fagnes – Belgium)

Abstract. Dust deposition in southern Belgium is estimated from the geochemical signature of an ombrotrophic peatland. The rare earth elements (REE) and lithogenic elements concentrations, as well as Nd isotopes, were determined by HR-ICP-MS and MC-ICP-MS, respectively, along an ∼ 6 m peat section covering 5300 yr, from 2000 to 7300 cal BP, dated by the 14 C method. Changes in REE concentration in the peat correlate with those of Ti, Al, Sc and Zr that are lithogenic conservative elements, suggesting that REE are immobile in the studied peat bogs and can be used as tracers of dust deposition. Peat humification and testate amoebae were used to evaluate hydroclimatic conditions. The range of dust deposition varied from 0.03 to 4.0 g m −2 yr −1 . The highest dust fluxes were observed from 2750 to 2550 cal BP and from 5150 to 4750 cal BP, and correspond to cold periods. The εNd values show a large variability from −13 to −5, identifying three major sources of dusts: local soils, distal volcanic and desert particles.
