Summary: Two distinct variabilities of the East Asian summer monsoon (EASM) on orbital timescales are observed, with strong correlations found between mineral assemblages and reflectance spectra. The differences in spectral signatures between sediments in the south Bohai Sea and other proxies may suggest an integrated forcing of solar insolation and ice-sheet evolution in the late Quaternary. The EASM record in the Bohai Sea helps fill the gap in understanding EASM variability on orbital timescales, highlighting the importance of studying diverse proxies for a comprehensive understanding.

Summary: The variability of the South Asian summer monsoon (SASM) is primarily influenced by high-latitude summer insolation in the Northern Hemisphere, rather than local insolation. Remote insolation has a negative impact on SASM variability. It affects the SASM by influencing the position of the South Asian high.

Summary: In this study, sensitivity experiments were conducted in a climate model to investigate the impacts of insolation changes on the East Asian winter monsoon and Australian summer monsoon during the early and middle Holocene. The results showed that the East Asian winter monsoon is enhanced due to local insolation changes, while the Australian summer monsoon is enhanced due to remote forcing from both the Northern Hemisphere low latitude and Southern Hemisphere high latitude.

Summary: Based on a geological record from the Nima Basin, it is shown that the South Asian monsoon (SAM) had advanced to the central Tibetan Plateau at least 27.3 million years ago, and intensified around 25.8 million years ago. These findings suggest that the monsoon changes were driven by the uplift of the plateau and astronomical factors.

Summary: This study investigates the hydrological cycle in Northern China during the Pliocene using a continuous cyclostratigraphic record. The results show that the hydrological cycling in the region was controlled by long and short orbital eccentricity. The expansion of the Antarctic ice sheet and the orbital configuration around 4.2-4.4 Ma may have contributed to the strengthening of the East Asian summer monsoon.

Summary: This study aims to distinguish the contributions of short-term climatic fluctuations and long-term tectonic forcing to Late-Quaternary fluvial incision by measuring Cl-36 concentrations in Jurassic limestones. The results show that fluvial incision is influenced by both climatic fluctuations and resistant lithologies. Gorges connected to glaciers exhibit a significant response to climatic variations, while disconnected gorges are in agreement with long-term tectonic forcing.

Summary: This study calibrated the astronomical time scale of an Upper Triassic lake sediment succession at St. Audrie's Bay (UK) using statistical tuning approaches, and successfully correlated it with reference sections in the Newark Basin (USA) and Jameson Land Basin (Greenland). The reconstructed lake level changes at St. Audrie's Bay were in-phase with those in the Newark Basin but in anti-phase with those in the Jameson Land Basin, supported by paleoclimate modeling. These hydrological changes in the basins were paced by a 1.8 million-year cyclicity, representing the fingerprint of chaotic behavior of the Solar System.

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: 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: We derived a record of abyssal ventilation spanning 4.7 million years and evaluated its linkage to Antarctic bottom water (AABW) formation by analyzing marine ferromanganese nodules from the eastern Pacific. Our findings showed a relative weakness in abyssal ventilation during the early Pliocene, with a persistent intensification from 3.4 million years ago. We identified seven episodes of AABW formation collapse since the late Pliocene, coinciding with key stages of Northern Hemisphere glaciation, indicating a possible link between the collapse events and global glaciation.

Summary: The study reveals a consistent sedimentary magnetic mineral assemblage dominated by pseudo-single-domain magnetite (Fe3O4) in surficial sediments in the western Pacific, although the ratio of detrital and biogenic magnetite particles varies between different sites. The measured magnetic parameters, including coercivity, show a general correlation with sedimentary redox conditions, with the coercivities obtained by mathematical unmixing exhibiting a stronger linkage and explaining about a quarter of variance of redox changes. These findings confirm the potential of magnetic properties in tracing abyssal redox changes in the western Pacific, while emphasizing the need for further investigation into the complex magnetic-redox relationships.

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.

Summary: The cause of ice-age cycles is still not fully understood, and studying the timing and magnitude of mountain glaciations can provide valuable insights. This study presents new dating results from the Niqingqu Valley in the Tibetan Plateau, showing multiple glacial activities prior to the Penultimate Glacial Maximum. The findings suggest that low atmospheric CO2 content and reduced summer solar insolation/high summer-monsoon precipitation played a role in these glacial fluctuations.

Summary: Through sediment records from Lake Nanyi in the lower Yangtze, we found that anthropogenic fire activity played a dominant role in the region, and the temporal pattern of fire activity was asynchronous from east to west. Archaeological evidence suggests an inverse relationship between agricultural and population levels and fire intensity during the mid-Holocene, with fire intensity being influenced by the diversity of landscape types associated with pre-historic subsistence patterns. Overall, changes in regional water-level delayed the transition from hunting-gathering to agriculture in the lower Yangtze region.

Summary: This paper argues that sessile barnacles are an excellent proxy for palaeoenvironmental reconstructions. The shells of barnacles consist of diagenetically stable low-magnesium calcite and record short-term variations. Analyses of several Western Mediterranean barnacle-rich deposits demonstrate the utility of barnacles as proxies for water depth, distance from the coastline, and hydrodynamic conditions. Moreover, the stable isotope ratios of barnacle shells can provide detailed palaeoenvironmental information.

Summary: The Late Ordovician mass extinction occurred during an ice age, with maximum ice coverage and a substantial drop in global sea level. This led to the exposure or shallowing of shallow tropical shelf environments. The study suggests that the burial rate of nutrient phosphorus (P) on shelves was minimal during this glacial period, leading to excess bioavailable P entering the open ocean and stimulating phytoplankton production, which in turn lowered oxygen concentrations.
