Abstract Extra-tropical circulation systems impede poleward moisture advection by the Indian Summer Monsoon. In this context, Himalayan range is believed to insulate south Asian from extra-tropical influences and delineate northern extent of Monsoon in central Asia. Paleoclimatic evidence, however, suggests increased availability Early Holocene north which attributed an intensification Nevertheless, mechanisms leading a surpassing maximum summer monsoonal influence remain unknown. Here we...
Abstract. Varved lake sediments provide climatic records with seasonal to annual resolution and low associated age uncertainty. Robust detailed comparison of well-dated annually laminated sediment is crucial for reconstructing abrupt regionally time-transgressive changes as well validation spatial temporal trajectories past changes. The VARved DAtabase (VARDA) presented here the first data compilation varve chronologies palaeoclimatic proxy records. current version 1.0 allows published from...
In slowly deforming tectonic settings (e.g., European Alps), large earthquakes occur too infrequently to be adequately represented in instrumental and historical records. This leads uncertainties inaccuracies of seismic hazard estimations. To extend the record, lacustrine paleoseismologists usually resort sedimentary archive lakes where can recorded as mass-transport deposits associated turbidites. The imprint shaking is generally more subtle poorly understood small (<2 km2) with...
Abstract Subaqueous paleoseismic studies used soft sediment deformation structures (SSDS) to discern the shaking strength of past earthquakes, as degree SSDS related Kelvin Helmholtz Instability evolves from disturbed lamination and folds intraclast breccia with higher peak ground accelerations (PGA). We lack comparative different types earthquakes seismogenic sources comprehend how these factors modulate earthquake‐induced deformation. Here, we compile records seven earthquake‐triggered 10...
Imaging techniques, such as micro-X-ray fluorescence (&#181;-XRF), are critical tools for paleoenvironmental reconstructions. Recent advances in two-dimensional (2D) mapping enable detailed spatial and temporal analyses of paleoclimate archives, providing unprecedented insights into past environmental changes. However, generating high-resolution geochemical maps often requires tradeoffs between measurement time data quality. Limited exposure times per pixel result low counts frequent...
Aquatic macrophytes from a lacustrine environment are highly prone to reservoir effect, resulting in an overestimation of age. This is often caused by the incorporation dissolved carbon (CO 2 and HCO 3 – ) through photosynthesis lake waters that have different 14 C activity than atmosphere. The atmosphere-water disparity produced mixing between water body its terrestrial surroundings, process temporal variations. Thus, only comprehensive understanding budget over time enables reliable...
The sediment profile from Lake Gościąż in central Poland comprises a continuous, seasonally resolved and exceptionally well‐preserved archive of the Younger Dryas (YD) climate variation. This provides unique opportunity for detailed investigation lake system responses during periods rapid cooling (YD onset) warming termination). new varve record presented here spans 1662 years late Allerød (AL) to early Preboreal (PB). Microscopic counting an independent chronology with YD duration...
Abstract Understanding how large river systems will respond to an invigorated hydrological cycle as simulated under higher global temperatures is a pressing issue. Insights can be gained from studying past wetter-than-present intervals, such the North African Humid Period during early Holocene Epoch (~11–6 thousand years ago). Here we present 1,500-year-long annually laminated (varved) offshore sediment record that tracks seasonal discharge of Nile River Period. The reveals mobilization...
Abstract Reading the sediment record in terms of past climates is challenging since linking climate change to associated responses sedimentary systems not always straightforward. Here we analyze erosional response landscapes on Tibetan Plateau interglacial forcing. Using theory dynamical Holocene time series geochemical proxies, derive a model that accurately simulates observed proxy variation three lake records. The suggests millennial variations composition reflect self‐organization abrupt...
Abstract. The Varved Sediments Database (VARDA) was launched in 2020 and aimed to establish a community database for annually resolved chronological archives with their associated high-resolution proxy records. This resource would support reproducibility through accessible data the paleoclimate modelling communities. In this paper, VARDA has been extended by dataset of European tephra geochemical metadata enable synchronisation varve records during Last Glacial–Interglacial Transition (LGIT;...
Abstract. Varved lake sediments provide long climatic records with high temporal resolution and low associated age uncertainty. Robust detailed comparison of well-dated annually laminated sediment is crucial for reconstructing abrupt regionally time-transgressive changes as well validation spatial trajectories past changes.

The Mediterranean region is recognized as a climate change hotspot, where temperatures increase faster than the global average. Modelling experiments suggest that such rapid and drastic changes will induce droughts extreme rainfall events in this vulnerable region. Records of past climatic are useful to determine speed mode regional responses sensitivities. We examine here response southern European hydroclimate large-scale oceanic disturbances during Younger Dryas (YD) interval (e.g., 14-11...
