The Middle East (ME) spans the transition between a temperate Mediterranean climate in Levant to hyper-arid sub-tropical deserts southern part of Arabian Peninsula (AP), with complex alpine topography northeast feeding Euphrates and Tigris rivers which support life Southeastern Fertile Crescent (FC). Climate projections predict severe drying several parts ME response global warming, making it important understand controls hydro-climate perturbations region. Here we discuss 23 speleothem...
Abstract The variability of the northern westerlies has been considered as one key elements for modern and past climate evolution. Their multiscale behavior underlying control mechanisms, however, are incompletely understood, owing to complex dynamics Atlantic sea-level pressures. Here, we present a multi-annually resolved record westerly drift over 6,500 years from Italy. In combination with more than 20 other westerly-sensitive records, our results depict non-stationary westerly-affected...
Abstract. Reconstructing the spatio-temporal dynamics of glaciations and permafrost largely relies on surface deposits is therefore a challenge for every glacial period older than last due to erosion. Consequently, remain poorly constrained worldwide before ca. 30 ka. Since speleothems (carbonate cave deposits) form from drip water generally indicate absence an ice sheet permafrost, we evaluate how speleothem growth phases defined by U series dates align with past glacial–interglacial...
Understanding the dynamics between East Asian summer (EASM) and winter monsoon (EAWM) is needed to predict their variability under future global warming scenarios. Here, we investigate relationship EASM EAWM as well mechanisms driving during last 10,000 years by stacking marine terrestrial (non-speleothem) proxy records from realm. This provides a regional independent signal for both monsoonal systems. The respective was subsequently analysed using linear regression model. We find that phase...
Abstract The impact of volcanic and solar forcings on multi-decadal climate change during the Holocene remains unclear. Here, we analysed stable isotopes fluid inclusions in a stalagmite to investigate hydroclimate responses Northwest Pacific region. Our data, covering active volcanism period mid-Holocene, showed that start large eruption clusters tends coincide with an onset or ongoing cooling phase. one largest eruptions Holocene, likely at Kikai caldera, is recorded as amplified scale...
Abstract High-resolution paleoclimate data on stable isotopes in a stalagmite were coupled to glycerol dialkyl tetraethers (GDGTs). The Indian Summer Monsoon (ISM) transitioned from limited rainfall during the Last Glacial Maximum (LGM) intense precipitation early Holocene (22 6 ka). This was associated with changes growth, abundance of branched (br) and isoprenoid (iso) GDGTs, as well δ 18 O, 13 C, Sr/Ca GDGT-derived signals providing both temperature moisture information. reconstructed...
Polarity reversals of the geomagnetic field have occurred through billions years Earth history and were first revealed in early 20th century. Almost a century later, details transitional behavior during excursions remain poorly known. Here, we present multidecadally resolved excursion record from radioisotopically dated Chinese stalagmite at 107-91 thousand before with age precision several decades. The duration directional oscillations ranged centuries 106-103 to millennia 98-92 present,...
We present a monthly dataset (AD 2002–2005) of rare earth elements (REEs) recorded in Porites coral, which were obtained from the Weizhou Island (WZI), Beibu Gulf, northwest South China Sea (SCS). This offshore coral shows strong seasonal cycle REE/Ca ratios, with enriched REEs (total REEs, 100~140 ppb) winter and depleted (40~60 summer. Since influence river discharge is limited to mouth, its contribution dissolved negligible for area WZI. Given similar pattern Ba/Ca, we suggest that...
The tufa deposits in the Kurkur–Dungul area, southern Egypt, date from marine isotope stage (MIS) 11 to MIS 1. Springs across region were active during glacial periods (with sea-level below –50 m), reflecting changed atmospheric circulation over Indian Ocean, as well peak interglacial periods. During times of low sea-level, reduced Indonesian throughflow promoted formation an Ocean Warm Pool, and anomalous rainfall on its western margin. We suggest that Egypt lies at intersection westerly...
Previous paleoclimatic studies by Asian cave records have shown that variability in the summer monsoons is well correlated with local insolation, North Atlantic climate, and Greenland stadial-interstadial cycles on millennial to orbital time-scales. However, it remains unclear whether a similar agreement exists short timescales. With 230Th dates precision as good ±62 years, we present decadal-resolved δ18O record covering 30.0–22.7 thousand years ago (ka) from stalagmite of Son La Province,...
Abstract Precisely dated high‐resolution speleothems may record past typhoon events, however, the state of art cave monitoring is a prerequisite to identify suitable stalagmites for reconstruction such events. With this motivation, we examined isotopic composition (δ 18 O and d‐excess values) rainfall, outside river, drip water, an underground river in Xianyun system, located southeastern China. Monthly bi‐monthly environmental conditions was conducted 1 year, from December 2018 2019,...
