Early–Middle Holocene Evolution of Lake Ice Cover Duration in Northeast China
Seasonal temperature reconstructions provide a critical approach for reconciling discrepancies between paleoclimate model simulations and proxy records. However, cold-season temperature variations remain poorly constrained due to the scarcity of robust cold-season temperature proxies. This study provides critical insights into lake ice-covered season temperature dynamics in Northeast China, a region where cold-season climate variability has remai…
Tracing sugarcane cultivation through the past two millennia using biomarkers in sediments of Huguangyan Maar Lake, South China
It is increasingly recognized that human activities-such as crop cultivation and biomass burning-have become dominant drivers of vegetation change, surpassing the influence of climate in many regions. However, the effects of human activities on vegetation change over the past two millennia remains unclear. Here, we present a biomarker record spanning the last two millennia from the Huguangyan Maar Lake in tropical China. The δ 13 C values of long…
Temperature variability in northeastern China over the Past 2000 Years
Holocene summer temperature record based on branched tetraethers in Northeast China
The temperature evolution during the Holocene shows conflicting patterns and yields the controversy regarding whether the Holocene followed a warming or cooling trend. Resolving this controversy is critical for understanding the underlying mechanisms of climate change and evaluating global warming on a longer timescale. Here we present a quantitative summer temperature reconstruction based on branched glycerol dialkyl glycerol tetraethers analyze…
The Sihailongwan Maar Lake, northeastern China as a candidate Global boundary Stratotype Section and Point for the Anthropocene series
Sihailongwan Maar Lake, located in Northeast China, is a candidate Global boundary Stratotype Section and Point (GSSP) for demarcation of the Anthropocene. The lake's varved sediments are formed by alternating allogenic atmospheric inputs and authigenic lake processes and store a record of environmental and human impacts at a continental-global scale. Varve counting and radiometric dating provided a precise annual-resolution sediment chronology f…
Plant-wax carbon isotopic evidence of Lateglacial and Holocene climate change from lake sediments in the Yin Mountains, inner Mongolia
Distribution and carbon isotopic composition of long-chain leaf wax n-alkanes from Holocene lake sediments in the Altai Mountains
N -Alkanes and compound carbon isotope records from Lake Yiheshariwusu in the Hulun Buir sandy land, northeastern China
The Hulun Buir sandy land in northern China is located at the northern limit region of the East Asian summer monsoon (EASM) and is therefore sensitive to the extension of the front of the rainfall belt. Here we report an n-alkane and compound-specific carbon isotope record from the Holocene sediments of Lake Yiheshariwusu in the middle of the Hulun Buir sandy land. The sediments contain a suite of n-alkanes with a strong odd over even carbon numb…
High-resolution geochemical record for the last 1100 yr from Lake Toson, northeastern Tibetan Plateau, and its climatic implications
Long-chain alkenone-inferred temperatures from the last deglaciation to the early Holocene recorded by annually laminated sediments of the maar lake Sihailongwan, northeastern China
Abrupt temperature changes during the last deglaciation are well recognized in Greenland ice cores and in deep-sea sediment records. On the continent of monsoonal Asia, however, only a few terrestrial temperature reconstructions extend to the Younger Dryas (YD). This hampers the understanding of how the Asian monsoon system responded to large-scale boundary changes in ice-sheet dynamics and reorganizations of atmospheric–oceanic circulation betwe…
High-resolution magnetic and palynological records of the last deglaciation and Holocene from Lake Xiarinur in the Hunshandake Sandy Land, Inner Mongolia
High-resolution mineral magnetic and pollen records from overlapping piston cores from Lake Xiarinur (42°37′N, 115°28′E) document detailed changes in environment and vegetation since the last deglaciation in the Hunshandake Sandy Land, Inner Mongolia. The formation of Lake Xiarinur commenced during the Bølling–Allerød warming, as reflected by an abrupt shift in sedimentary facies from eolian sands to lacustrine sediments at a core depth of 3.5 m …
A 1000-yr record of environmental change in NE China indicated by diatom assemblages from maar lake Erlongwan
Past environmental changes based on diatom relative abundances have been inferred from the maar Lake Erlongwan in northeast China. The limnology of Lake Erlongwan is affected by the strongly seasonal regional climate. The composition of diatom assemblages, in turn, responds to changes in the seasonal duration of ice cover in winter, water-column turnover in spring and autumn, and thermal stratification in summer. Statistical analysis of the sedim…
Palaeovegetation and palaeoclimate in low-latitude southern China during the Last Glacial Maximum
Seasonal temperature variability during the past 1600 years recorded in historical documents and varved lake sediment profiles from northeastern China
Seasonal temperature variability over longer timescales could offer new insights into understanding different forcing factors and response processes in the climate system. Here we report an alkenone-based temperature reconstruction for growing season over the past 1600 years from the varved sediment in Lake Sihailongwan, northeastern China. The most notable cold spells occurred during the periods ad 480–860, ad 1260–1300, ad 1510–1570 and ad 1800…

Reconstruction of climate and vegetation changes of Lake Bayanchagan (Inner Mongolia)
A high-resolution pollen and Pediastrum record, spanning 12,500 yr, is presented for Lake Bayanchagan , southern Inner Mongolia. Individual pollen taxa (PT-MAT) and the PFT affinity scores (PFT-MAT) were used for quantitative climatic reconstruction from pollen and algal data. Both techniques indicate that a cold and dry climate, similar to that of today, prevailed before 10,500 cal yr B.P. The wettest climate occurred between ∼10,500 and 6500 ca…
The ‘Mediaeval Warm Period’ drought recorded in Lake Huguangyan, tropical South China
The geochemistry of dated sediment cores from Lake Huguangyan (21°9′N, 110°17′E), tropical South China, reveals distinct stratigraphical patterns in total organic and inorganic carbon (TOC, TIC), biogenic silica (BS) and total nitrogen (TN) over the past 1400 years. In this hydrologically closed lake, TIC variations may re‘ ect changes in the precipitation/evaporation ratio, which controls the evaporative enrichment of carbonate. TOC, BS and TN i…
