“…4) as shown by the progressive decrease in natural forest species and the increase in xerophytes such as Artemisia. This agrees with previous 15 paleoclimatic studies in the western Mediterranean, which document a progressive aridification trend since ~7000 cal yr BP (Carrión et al, 2002;Fletcher and Sánchez Goñi, 2008;Jalut et al, 2009;Carrión et al, 2010;Anderson et al, 2011;Jiménez-Moreno et al, 2012. Jiménez- Moreno et al ( , 2015 suggested that semidesert expansion and Mediterranean forest decline during the late Holocene in this area could be explained by decreasing summer insolation (Laskar et al, 2004;Fig.…”

“…This suggests that higher fire activity at this time could have been related to the presence of abundant fuel load (Daniau et al, 2007;Linstädter and Zielhofer, 2010;Jiménez-Moreno et al, 2013b). Nevertheless, two different records in Sierra de Cazorla show a reverse trend in fire activity during this period (Carrión et al, 2001b;Carrión et al, 2002), which may be due to different characteristics in fire regimes related with precipitation (Linstädter and Zielhofer, 2010;Jiménez-Moreno et al, 2013b). For example, in typically arid and semiarid environments in the Mediterranean area fuel load limits fire regimes.…”

“…Pinus dominates the AP pollen sum throughout much of the Holocene in the Sierra Nevada region and this is the reason we pay special attention to this pollen taxa. Pinus nigra and Pinus sylvestris occur at present in the Sierra Nevada oromediterranean vegetation belt, between 1600-2100 m asl (Carrión et al, 2002) and 1600-2200 m asl (Castro et al, 2004), respectively. Pollen sedimentation studies show that in locations where Pinus is present, its percentage is approximately 50-60% of the total pollen sum (Andrade et al, 1994).…”

“…Martín-Puertas 2008; Morellón et al, 2011;Currás et al, 2012;Corella et al, 2013). Most of the Holocene paleoclimate reconstructions in the southern Iberian Peninsula come from lake and peat deposits at low and montane altitudes, as well as from marine cores (Carrión, 2002;Carrión et al, 2001aCarrión et al, , 2001bCarrión et al, , 2003Carrión et al, , 2007Carrión et al, , 2010Martín-Puertas et al, 2008, 2010Nieto-Moreno et al 2011;Jiménez-Moreno et al, 2015). Studies at higher elevations are scarcer and mostly come from lake and peat bog sedimentary deposits from the Sierra Nevada range (Anderson et al, 2011;Jiménez-Moreno and Anderson, 2012;García-Alix et al, 2012Jiménez-Moreno et al, 2013b).…”

Highlights1. We studied a late Holocene vegetation and fire record from southern Spain.2. A long-term aridification trend is observed, interrupted by shorter-scale variability.3. This study shows humidity changes during the last 4500 yr, related to NAO changes and solar variability. AbstractHigh-resolution pollen analysis, charcoal, non-pollen palynomorphs and magnetic susceptibility have been analyzed in the sediment record of a peat bog in Sierra Nevada in southern Iberia. The study of these proxies provided the reconstruction of vegetation, 2 climate, fire and human activity of the last ~4500 cal yr BP. A progressive trend towards aridification during the late Holocene is observed in this record. This trend is interrupted by millennial-and centennial-scale variability of relatively more humid and arid periods. Arid conditions are recorded between ~4000 to 3100 cal yr BP, being characterized by a decline in arboreal pollen and with a spike in magnetic susceptibility. This is followed by a relatively humid period from ~3100 to 1600 cal yr BP, coinciding partially with the Iberian-Roman Humid Period, and is indicated by the increase of

“…The latitudinal amplitude of this middle zone could have been larger during phases of climate cooling weaker than the 8 cal ka BP event. In southern Spain, this event has been recorded as lake level oscillation such as Lake Siles-Jaen (Carrión, 2002) and Laguna de Medina level drops (Reed et al, 2001), close to the coast of Cadiz (Fig. 1).…”

Sea level and clima te changes archived in various coastal environments during the last part of the last glacial and present interglacial periods are investigated by interpolating available geomorphology, sedimentology, palaeontology and geochronology data. The coastal response to these changes depended on the environment and geographic location. Changes of sea level during the rising, transgressive phase are well recorded in the sedimentary filling of the estuaries, whereas during the phase of highstand they are best recorded in beach-barrier environments. The postglacial rise of sea level took place in two phases: a rapid rise until 6500 cal BP, and a second phase of near stability with minor oscillations of metric magnitude. Regarding climate changes, there is no record of changing temperatures in the coastal zones of southern Spain, although there is in precipitation and wind intensityjvelocity. After 7-5 cal ka BP, the general climatic trend towards aridity was punctuated by several short-lived (centennial) episodes of increased aridity that occurred with a millennial cycle, often coincident with Bond cool events and, in sorne cases, with decreases of sea surface temperatures. The absence of human in ter ventio n in vegetation composition until 2000 BP suggests that most environmental coastal shifts were climatically driven,

As the largest alpine wetland and peat deposition area in China, the Zoige wetland is climatically sensitive. The organic matter (OM) in peat stores copious environmental information. Here we report new data on the organic geochemistry of a 4.5 m peat profile HY2014 from southern Zoige wetland. Based on closely spaced accelerator mass spectrometry (AMS) 14C dating, we established a high‐resolution geochronological framework beginning at 14,057 a BP. Moreover, we estimated the sedimentation flux of TOC and TN (SFs) and their influencing factors. Before 10,916 a BP, the lake shrunk and peat began to develop under cold and dry conditions, and SFs were at their lowest values due to low productivity. More OM originated from hydrophyte and marsh plants. From 10,916 to 3050 a BP, peat was widely and well developed, and the climate was warm and humid, despite a cooling and drying trend. The HY2014 profile experienced an optimum climate during 10,916 − 6000 a BP, when SFs had the highest values that benefited from high productivity, and OM mainly originated from terrestrial plants. After 3050 a BP, the climate was the coldest and driest. The high SFs over the past 2000 a BP were mainly resulted from the low decomposition rate. The plant community, primary productivity, and decomposition rate were closely linked with the temporal variation of SFs. The environment change was mainly controlled by summer solar insolation, and the Zoige wetland was significantly influenced by the Indian summer monsoon.
