Summary: This paper studies the relationships and influential factors of landslides in the densely distributed Chinese Loess Plateau (CLP). It finds that the area-volume relationship of landslides follows a power law trend and that the majority of landslides are long run-out landslides. The size of landslides increases with an increase in hypsometric integral, and factors such as loess thickness, human activities, and slope have both positive and negative effects on landslides in the CLP. The study also suggests that landslide risk will increase with climate change.

Summary: The loess sequences of the Chinese Loess Plateau provide a comprehensive paleoclimatic archive for the Neogene-Quaternary period. Geochronology data reveal spatial variability in sediment provenance across the plateau, with at least three distinct provenance zones recognized. This challenges the traditional view that attributes Quaternary loess primarily to deserts north and west of the plateau, suggesting a more significant role of fluvial processes and precipitation in dust production. The nonuniformity in sediment provenance raises questions about the validity of using CLP-derived paleoclimate information for regional interpretations.

Summary: This study investigated the sources of sediments in different areas of the Chinese Loess Plateau (CLP) using SEM and material modal composite analysis. The results show that the formation of loess particles is related to differential weathering and precipitation mediated dissolution. The changes in hornblende concentrations provide evidence for sediment provenance in the deserts north and west of CLP. Understanding sediment sources is crucial for tracing Asian monsoon evolution and may challenge the interpretation of the monsoon mechanism.

Summary: Previous studies suggest that the northeastern Tibetan Plateau is the major source area for the Chinese Loess Plateau. However, the origin of the eastern CLP and the relationship between loess and proximal river sediments have never been systematically studied, which hinders our understanding of the surface process between source and sink.

Summary: The study focused on groundwater recharge in hillslopes on the Chinese Loess Plateau, finding that recharge is primarily facilitated by soil matrix flow and rates are lower than on flat landscapes. Recharge rates ranged from 24.5 to 33.8 mm yr(-1), accounting for 4%-7% of long-term precipitation. Groundwater recharges were mainly controlled by soil texture and land use changes, with little impact from climatic differences between watersheds.

Summary: The research focused on the Australasian microtektites in the Chinese Loess Plateau revealed potential microtektites but ultimately did not discover any, suggesting that microtektites are not widespread stratigraphic markers in the CLP. The study also confirmed that microtektites in this strewn field were preferentially deposited at the downrange of the impactor trajectory.

Summary: Understanding the mechanical behavior of compacted loess is crucial for construction on the Loess Plateau. Through a series of tests, including compression tests, shear tests, and scanning electron microscope imaging, the variations in compressibility, shear strength, and microstructure of compacted loess at different dry densities and water contents were investigated. The relationship between pore microscopic indicators and mechanical parameters was analyzed through statistical analysis. The results showed that the compression coefficient decreases with increasing dry density and cohesion and internal friction angle decrease with increasing water content. The structure of compacted loess evolves from overhead-mosaic-flocculation with increasing compactness and saturation.

Summary: In this study, it was found that nearly 80% of the study area in the Chinese Loess Plateau has undergone greening, with human land use management rather than rainfall being the main driver for rapid vegetation change. Urban expansion was identified as the primary driver for rapid vegetation browning. Additionally, GDP growth was found to promote both browning and greening, demonstrating sustainable development in the region. These findings highlight the complex relationship between human activities and vegetation dynamics in the Loess Plateau.

Summary: Loess deposits in southeastern China are important for paleoclimate reconstruction. Luminescence dating of a loess-paleosol sequence in northern Jiangsu Province using SAR-OSL and pIRIR protocols revealed accurate ages up to -70 ka, confirming Last Glaciation deposition. However, beyond 70 ka, quartz ages are underestimated while pIRIR ages are likely overestimated, highlighting the challenges of dating methods for older samples.

Summary: This study presents a new approach to determine the provenance of eolian sediments from the Chinese Loess Plateau. By using a multi-proxy (zircon, monazite, and rutile) U/Th-Pb geochronology approach, the researchers found spatial variability in sediment provenance and its potential relationship with westerly/northwesterly winds. These findings have important implications for the study of the provenance of eolian deposits worldwide.

Summary: In this study, loess records and climate simulation results were used to compare the climate differences between MIS-9 and MIS-11 in China and central Asia. The results showed that MIS-9 was relatively wetter in southern central Asia due to higher insolation and that both insolation and greenhouse gases contributed to slightly higher precipitation and evaporation in northern China during MIS-9 compared to MIS-11. Additionally, the higher insolation and greenhouse gas concentration during MIS-9 generated an anomalous atmospheric circulation pattern similar to the negative phase of the North Atlantic Oscillation, favoring precipitation increase in southern central Asia.

Summary: The study presents an extensive dataset of Holocene seasonal temperatures reconstructed using pollen records in the Northern Hemisphere. The results show that both summer and winter temperatures warmed in the early to mid-Holocene and cooled thereafter, with variations across different regions. The early Holocene warming trend is consistent with model simulations, but the cooling in winter season is not well reproduced by climate models.

Summary: The loess-paleosol sequences in the Chinese Loess Plateau are an important terrestrial paleoclimate record, but there is still limited quantitative understanding of the response of paleosol development to different climate and environmental factors. This study used combined soil-climate models to investigate the sensitivity of paleosol development to various soil forming factors and the influence of ice sheets and astronomical forcing during interglacials over the past 500,000 years. The results show that precipitation, dust addition, and evapotranspiration are the dominant factors controlling interglacial paleosol formation, and their importance varies between interglacials and for different soil properties. The simulated paleosols mainly result from the joint effect of precession and ice sheets via their control on local climate and show qualitative agreement with observations.

Summary: Research has found that the injection of Meltwater Pulse 1A into the North Atlantic weakened the Atlantic Meridional Overturning Circulation and caused severe winter temperature drop in the Northern Hemisphere. This extreme cooling triggered the BOlling warming event and led to the recovery of the Atlantic Meridional Overturning Circulation.

Summary: The upper sandy loess unit L9 on the Chinese Loess Plateau represents aeolian deposition under conditions of extreme aridification, but the forcing mechanism is still controversial. Paleomagnetic studies show that in the eastern CLP, the coarsest part of L9 is remagnetized and has a normal geomagnetic polarity, while in the western CLP, it records a primary reverse polarity. This spatially inconsistent magnetization pattern is mainly due to different magnetic carriers in the two regions (hematite in the west and magnetite in the east), suggesting different dust provenance. This spatial contrast is attributed to the episodic uplift of the northeastern Tibetan Plateau, which also caused extreme aridification of the East Asian interior at approximately 900 ka.

Summary: Typical patterns of Late Pleistocene loess-paleosol units are preserved in Novo Orahovo brickyard, Northern Serbia. Preliminary luminescence chronology supports the chronostratigraphic interpretations of global isotopic marine climate reconstructions. Magnetic susceptibility and sedimentological evidence show general similarities with marine oxygen-isotope stratigraphy. These records provide new insights into dust accumulation regimes over the eastern side of the Backa loess plateau and offer new paleoenvironmental information for the region. They represent an important step towards establishing a catena from the thin loess-like sediments of the Banat foothills in the east to the thicker and seemingly more complete loess sections of the southeastern and central Carpathian Basin. Grain-size data from the loess record of Novo Orahovo explain the regional differentiation in dust deposition.

Summary: The North Atlantic jet stream has a significant impact on the climate of the North Atlantic-European region, particularly in winter. Recent observations have shown that the winter jet stream has strengthened over the past 140 years, and this trend has deviated from natural variability. Researchers have discovered that the appearance of the North Atlantic warming hole, caused by anthropogenic forcing, is the most likely explanation for this anomalous trend. Continued global warming may further strengthen the jet stream in the future.

Summary: Widespread and frequent droughts have affected most parts of Europe over recent years. The onset of the drying trend in southern Europe occurred around the 1850s, and anthropogenic warming has enhanced the strength of land-atmosphere coupling and exacerbated the widespread drying trend since then. This persistent drying trend in southern Europe is likely the result of warming and close coupling between soil moisture and atmospheric temperature.
