Abstract. Estimated external radiative forcings, model results, and proxy-based climate reconstructions have been used over the past several decades to improve our understanding of mechanisms underlying observed variability change millennium. Here, recent set temperature at continental-scale generated by PAGES 2k project a collection state-of-the-art simulations driven realistic forcings are jointly analysed. The first aim is estimate consistency between results for each region time...
Abstract. We have constructed a regional tree-ring cellulose oxygen isotope (δ18O) record for the northern Indian sub-continent based on two new records from India and central Nepal three published northwestern India, western Bhutan. The spans common interval 1743 to 2008 CE. Correlation analysis reveals that is significantly negatively correlated with climatic indices: all rainfall (AIR; r = −0.5, p < 0.001, n 138), monsoon index (IMI; −0.45, 51) intensity of monsoonal circulation (r...
Abstract The South Asian summer monsoon (SASM) is a major atmospheric synoptic climate system affecting nearly quarter of the human population. Climate proxy data derived from tree rings, ice cores, speleothems and other sources can all contribute to an understanding SASM variability prior instrumental period. Here, we develop optimal information extraction (OIE) method, which use reconstruct index (SASMI) over last millennium using 15 tree-ring chronologies. record generated significantly...
Abstract. The dominant modes of variability precipitation for the whole China over past millennium and mechanism governing their spatial structure remain unclear. This is mainly due to insufficient high-resolution proxy records in western China. Numerous tree-ring chronologies have recently been archived publicly available databases through PAGES2k activities, these provide an opportunity refine field reconstructions Based on 479 records, including 371 width chronologies, a isotope...
Sea ice is a highly dynamic and productive environment that includes diverse array of psychrophilic prokaryotic eukaryotic taxa distinct from the underlying water column. Because sea has only been extensive on Earth since mid-Eocene, it hypothesized bacteria adapted to inhabit have traits acquired through horizontal gene transfer (HGT). Here we compared genomes bacterium Psychroflexus torquis ATCC 700755T, associated with both Antarctic Arctic ice, its closely related nonpsychrophilic sister...
Abstract Identifying the position of Current Warm Period (CWP) in context long‐term climatic trend is vital for understanding impact human activity on climate change. Reconstructions summer temperature and precipitation eight subregions China over past 22,000 years show that CWP these are all lower than Early to Middle Holocene. The timing Holocene peaks northern (including Northwest China, North Northeast China) mainly determined by orbital forcing. Greenhouse gas forcing land ice‐sheet...
We developed two tree ring-width chronologies (Qilian juniper, Sabina przewalskii Kom.) for the inland Heihe River Basin in arid northwest China using a large number of tree-ring samples (217 samples/92 trees) with accurate information about pith offsets based on Regional Curve Standardization (RCS) and standard dendrochronological (STD) methodologies. Two 1422-year reconstructions annual (August–July) streamflow upstream region are presented. The STD RCS account 53.4% 57.2% actual variance...

Proteorhodopsins (PRs) are commonly found in marine prokaryotes and allow microbes to use light as an energy source. In recent studies, it was reported that PR stimulates growth survival under nutrient-limited conditions. this study, we tested the effect of nutrient salinity stress on extremely psychrophilic sea-ice bacterial species Psychroflexus torquis, which possesses PR. We demonstrated for first time light-stimulated occurs conditions rather than limitation elevated is related...

Abstract. Global drylands encompassing hyper-arid, arid, semiarid, and dry subhumid areas cover about 41% of the earth's terrestrial surface are home to more than a third world's population.

Abstract Changes in climate during the Roman Warm Period (RWP, 1–250 CE) and Late Antique Little Ice Age (LALIA, 536–660 play a critical role early societal evolution, but differences between these two periods possible causes of changes remain poorly explored.

Monsoon precipitation in China influences the livelihoods of approximately two-thirds its population, making an understanding regional patterns and long-term variability essential for improving future forecasts. However, relatively short span instrumental records limited skill climate models simulating hinder our ability to uncover driving mechanisms behind historical monsoon changes. To address these gaps, this study integrates multiproxy reconstructions with model simulations assimilate...
The Qinghai-Tibet Plateau has experienced rapid warming over the past six decades, resulting in more frequent extreme weather events with significant impacts on human health. This trend, along improved infrastructure and transportation, spurred a rise summer tourism, boosting local economies yet exposing visitors residents to high risks of public However, relationship between historical variability THW index health under combined influence external forcing factors internal climate remains...
Abstract The intensification of Northern Hemisphere Glaciation (iNHG) with the onset glacial‐interglacial cycles at ∼2.7 Ma had a profound impact on global climate system. However, there have been few systemic assessments response orbital‐scale East Asian summer monsoon (EASM) variability to iNHG, partly due controversies regarding interpretation dominant orbital rhythms EASM. Here, we present grain size and other proxy records from mainly silt‐sized lacustrine‐fluvial deposits in northern...
