Significance The Younger Dryas (YD) was an ∼1,300-y period of extreme climate that dramatically reversed the course global warming brought last Ice Age to a close. Understanding what mechanisms triggered and terminated this event remains enigmatic, but it is fundamental for gaining insights into inner workings Earth’s system. In study, we used combination well-dated speleothem ice-core records pinpoint timing its onsets terminations in various climatic regimes around world. We show YD...
Abstract. The full understanding of climate feedbacks responsible for the amplification deglaciations requires robust chronologies these transitions, but in case marine records, radiocarbon are possible only last glacial termination. Although assumed relationships between isotopic record and orbital parameters provide a first-order chronology terminations, an independent chronological control allows forcing response to be evaluated over multiple previous terminations. To assess this, we...
Abstract Palynological, sedimentological and stable isotopic analyses of carbonates organic matter performed on the El Portalet sequence (1802 m a.s.l., 42°48′00ʺN, 0°23′52ʺW) reflect paleoclimatic evolution vegetation history in central-western Spanish Pyrenees over last 30,000 yr, provide a high-resolution record for late glacial period. Our results confirm previous observations that deglaciation occurred earlier than northern European Alpine sites point to readvance from 22,500 18,000 cal...
During the period of instrumental records, North Atlantic Oscillation (NAO) has strongly influenced inter-annual precipitation variations in western Mediterranean, while some eastern parts basin have shown an anti-phase relationship and atmospheric pressure. Here we explore how NAO other circulation modes operated over longer timescales Medieval Climate Anomaly (MCA) Little Ice Age (LIA). High-resolution palaeolimnological evidence from opposite ends Mediterranean basin, supplemented by...
Abstract Millennial to submillennial marine oscillations that are linked with the North Atlantic's Heinrich events and Dansgaard–Oeschger cycles have been reported recently from Alboran Sea, revealing a close ocean-atmosphere coupling in Mediterranean region. We present high-resolution record of lithogenic fraction variability along IMAGES Core MD 95-2043 Sea we use infer fluctuations fluvial eolian inputs core site during periods rapid climate change, between 28,000 48,000 cal yr B.P....
A multiproxy study of sediment cores from Zoñar Lake (37°29′00″N, 4°41′22″W, 300 m a.s.l.) supported by 11 14 C AMS dates provides the first high-resolution centennial-scale reconstruction past humidity changes in southern Spain during last 4000 years. Arid periods occurred prior to 2.9 cal. kyr BP and 1.3—0.6 (`Mediaeval Climate Anomaly'). The most humid period 2.6—1.6 encompassing late Iron Age—Iberian Roman epochs. Two lower intensity between 0.8 0.6 (AD 1200—1400) about 400 yr (around AD...
The detailed analysis of the International Marine Past Global Changes Study core MD99‐2343 recovered from a sediment drift at 2391 m water depth north island Minorca illustrates effects climate variability on thermohaline circulation in western Mediterranean during last 12 kyr. Geochemical ratios associated with terrigenous input resulted identification four phases representing different climatic and deepwater overturning conditions Western Basin Holocene. Superimposed general trend, eight...
The oxygen isotope composition of speleothems is a widely used proxy for past climate change. Robust use this depends on understanding the relationship between precipitation and cave drip water δ18O. Here, we present first global analysis, based data from 163 sites, 39 caves five continents, showing that δ18O most similar to amount-weighted where mean annual temperature (MAT) < 10 °C. By contrast, seasonal climates with MAT > °C 16 °C, records recharge-weighted This implies (formed in near...
Abstract A sedimentological and geochemical study of the Lago Enol sequence (Cantabrian Mountains, northern Spain), together with detailed geomorphological mapping, provides a first record glacier evolution climate change over last 40 ka in Picos de Europa National Park. The retreated from its maximum extent prior to BP as demonstrated by onset proglacial lacustrine sedimentation two glaciated depressions: Comella hollow north (before BP) 38 BP). These results support previous evidence that...
Abstract The Central Ebro River Basin (NE Spain) is the most northern area of truly semi-arid Mediterranean climate in Europe and prehistoric human occupation there has been strongly influenced by this extreme environmental condition. Modern conditions single out region due to harsh environment, characterised highest absolute summer temperatures Basin. Bajo Aragón (SE Basin) was intensively populated during Early Holocene (9400–8200 cal yr BP) but settlements were abandoned abruptly at...
