Abstract The Holocene temperature conundrum, the discrepancy between proxy-based global cooling and simulated annual warming trends, remains controversial. Meanwhile, reconstructions simulations show inconsistent spatial patterns of terrestrial changes. Here we report alkenone records to address over mid-latitude Eurasia. In contrast with long-term trends in warm season temperatures northeastern China, from southwestern Siberia are characterized by colder conditions before ~6,000 years ago,...
Abstract The Chinese loess-paleosol sequences provide important archives for studying paleoenvironmental changes. However, the lack of independent and accurate time scales hinders study between loess other records. Asian stalagmite δ18O records indicate synchronous patterns paleoprecipitation over large geographic regions. record hydrogen isotopic composition plant wax (δDwax) in is also controlled by rainwater δD. Both share a common origin. linear relationship rainfall δD variance provides...
The carbon isotope values (δ13C) of aquatic plants are great significance for recognizing cycles and tracing environmental changes in lakes. Yet, the influence δ13C their utilizing sources (especially case CO2 separated from HCO3– water) on differences have never been evaluated, which is mainly due to lack investigations lake water. In this study, we used a newly developed fast-response automated gas equilibrator real-time concentration determination dissolved surface bottom water Lake...
Abstract A detailed uplift history of the Tibetan Plateau is essential for disentangling proposed geodynamical models and assessing its impacts on climate biodiversity. However, when how plateau formed remains highly controversial. Here, we present unusual geochemical indicators marine signatures in Cenozoic terrestrial strata Qaidam Basin, northern Plateau, with strong implications basin altitude. Our investigations across reveal typical alkenones anomalously high carbonate carbon isotopic...
Organic compounds could be adsorbed and even occluded within the macromolecular structures of kerogen. Studies concerning thermal evolution adsorbed/occluded hydrocarbons inside kerogens will helpful in understanding its structural characteristics features estimating effectiveness fractions. In this work, have been released from a low-matured kerogen upper Permian Lucaogou formation Santanghu Basin, northwest China, pyrolysis residues by solvent extraction oxidative treatment, respectively....
Hydrogen safety remains a paramount concern in pipeline transportation. Once hydrogen leaks and ignites, it quickly escalates into jet fire incident. The substantial thermal radiation released poses significant risks of explosion. Therefore, studying the characteristics fires developing accurate prediction models are crucial for establishing relevant standards. To address oversimplified consideration weighted coefficients models, this study investigated by carrying out experiments numerical...
The chronology of geological records in lacustrine, peatland and marine sediments for the late glacial depends mainly on 14C dating technology, which provides basic database global paleoclimate research. However, reservoir correction always challenges accuracy terrestrial uncertainty associated with carbon effect becomes critical high resolution studies. Here, based hypothesis synchronization precipitation isotopes, we verify identify a series in-phase points isotopes (IPPIs) between...
Precipitation isotopic composition variations that are directly recorded in geological samples play an important role understanding past hydroclimatic changes. In arid regions, the hydrogen isotopes of leaf wax (δDwax) loess sections can provide records summer precipitation isotopes. However, previous studies have primarily focused on orbital scale, and there was still a lack clear shorter timescales their implications for climate change. this study, we report centennial-resolution δDwax...
Abstract Contrasting moisture evolutions between westerlies‐dominated Central Asia and monsoonal since the mid‐Holocene have been widely recognized. Yet, inconsistent hydrological records over early Holocene from both regions hamper our understanding of hydroclimatic changes associated mechanisms. Here we present isotopic biomarker (alkenone) three Chinese lakes located at to address a possible meltwater role in lake water budget. Our results show occurrence particularly depleted values with...
