Seasonality of C 4 plant growth and carbonate precipitation in the Chinese Loess Plateau may cause positive carbon isotope anomalies in pedogenic carbonates
Carbon isotope analysis of pedogenic carbonate (δ 13 C Carb ) and soil organic matter (δ 13 C TOC ) is widely applied in reconstructions of terrestrial paleovegetation. The δ 13 C of different archives is considered well matched and equally reflects the proportion of C 3 /C 4 plant biomass covering the soil profile. However, modern soil and paleosol sequences provide substantial evidence that δ 13 C Carb and δ 13 C TOC do not always match, raisin…
Mineral magnetic properties of loess–paleosol couplets of northern Serbia over the last 1.0 Ma
We conducted the first detailed mineral magnetic investigation of more than nine loess–paleosol couplets of the composite Titel-Stari Slankamen loess section in Serbia, which provides one of the longest and most complete terrestrial record of paleoclimatic changes in Europe since ~1.0 Ma. The results show that the ferrimagnetic mineral assemblage of the loess units is dominated by partially oxidized multidomain (MD) and pseudo-single domain (PSD)…
Modulation of the relationship between summer temperatures in the Qinghai–Tibetan Plateau and Arctic over the past millennium by external forcings
The Qinghai–Tibetan Plateau and Arctic both have an important influence on global climate, but the correlation between climate variations in these two regions remains unclear. Here we reconstructed and compared the summer temperature anomalies over the past 1,120 yr (900–2019 CE) in the Qinghai–Tibetan Plateau and Arctic. The temperature correlation during the past millennium in these two regions has a distinct centennial variation caused by volc…
Onset and maturation of Asian summer monsoon precipitation reconstructed from intra-annual tree-ring oxygen isotopes from the southeastern Tibetan Plateau
We present a long-term seasonal tree ring cellulose oxygen isotope (δ 18 O c ) time series created by analyzing four segments (S1, S2, S3, and S4) per year during the period of 1951–2009 from southeastern Tibetan Plateau. This intraseasonal δ 18 O c reveals the onset and mature phase of the summer monsoon precipitation in this region. Analysis indicates that the δ 18 O c of S1 has the strongest correlation with precipitation during the regional m…
Paleowind directions from the magnetic fabric of loess deposits in the western Chinese Loess Plateau and implications for dust provenance
The aeolian loess-paleosol sequences in the Chinese Loess Plateau (CLP) are an excellent archive of variations in atmospheric circulation in the geological past. However, there is no consensus regarding the roles of the East Asian winter monsoon and westerly winds in transporting the dust responsible for loess deposition during glacial and interstadial periods. We conducted detailed measurements of the anisotropy of magnetic susceptibility (AMS) …

Synchronous multi-decadal climate variability of the whole Pacific areas revealed in tree rings since 1567
Oceanic and atmospheric patterns play a crucial role in modulating climate variability from interannual to multi-decadal timescales by causing large-scale co-varying climate changes. The brevity of the existing instrumental records hinders the ability to recognize climate patterns before the industrial era, which can be alleviated using proxies. Unfortunately, proxy based reconstructions of oceanic and atmospheric modes of the past millennia ofte…
Geochemical and grain-size evidence for the provenance of loess deposits in the Central Shandong Mountains region, northern China
Widespread loess deposits in the Central Shandong Mountains yield valuable paleoclimatic records for this currently semi-humid monsoonal region of northern China. The grain-size distribution and major element composition for bulk samples and two grain-size fractions ( 2 /Al 2 O 3 and K 2 O/Al 2 O 3 for the
Spatial and temporal changes of prehistoric human land use in the Wei River valley, northern China
Agricultural land use has been established as the dominant prehistoric human activity in early cultural centers for thousands of years. However, because of lack of data, there is still considerable debate about the amount and spatial distribution of prehistoric land use across the world. Quantitative reconstruction of it on the basis of human activity records, for example, archaeological data, is the key to resolving the issue. Here, we focus on …
Danube loess stratigraphy — Towards a pan-European loess stratigraphic model
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…

Medium or Message? Predicting Dimensions of Political Sophistication
This investigation examines the theoretical linkage between patterns of mass media news use and various dimensions of political sophistication through three empirical models of comparison. A between-medium model traces the cognitive effects to the form of media; a between-content model isolates effects attributable to content type; and a cross-medium model explores the possibility that the effects of one medium may be mediated by use of another m…
Ice-Volume Forcing of East Asian Winter Monsoon Variations in the Past 800,000 Years
Particle-size measurements of some typical loess-soil samples taken in different localities of the Chinese Loess Plateau demonstrate that the grain size ratio of 10 μm (%) can be used as an indicator of variations in intensity of the East Asian winter monsoon winds. Grain-size curves of the Baoji and Weinan sections show that this proxy indicator is very sensitive to loess-soil alterations. Analytical results also suggest that during soil-forming…
