Summary: This study presents a new sand dune accumulation record in the southeast Qilian Mountains, which provides insights into the late glacial and Holocene moisture variation. The results show that the climate was dry during the late glacial and early Holocene, peaked in the middle Holocene, and then became relatively dry in the late Holocene. The regional comparison suggests that the moisture variation pattern in the NE Tibetan Plateau is likely influenced by the changes in East Asian summer monsoon precipitation.

Summary: This study aims to understand the impact of extreme climate change on terrestrial ecosystems, focusing on the Inner Mongolian Plateau. Using vegetation index and meteorological data from 1982 to 2020, changes in vegetation patterns and extreme climate were identified in three ecological zones. Correlation analysis and geographical detector were used to quantify the effects of extreme climate on vegetation. The results show that forest, steppe, and desert steppe areas experienced significant increases in annual vegetation index. Extreme temperature intensity and frequency had a major impact on forest vegetation, while extreme precipitation intensity and frequency were more important for desert steppe vegetation. The response of vegetation to extreme temperature had a lag of at least three months, while extreme precipitation exhibited a two-month time lag. This study improves our understanding of extreme climate-vegetation interactions and provides support for disaster mitigation and ecological understanding of the Inner Mongolian Plateau.

Summary: Lakes over the inner Tibetan Plateau are sensitive to environmental and climate changes. This study examines a lacustrine section from a sandy shoreline in Dawa Co using luminescence and radiocarbon dating methods. The results show that quartz optically stimulated luminescence (OSL) dating yields younger ages than post-infrared IRSL (pIRIR) dating of K-feldspar fraction due to anomalous fading of quartz OSL signals. The AMS C-14 age of charcoal sample confirms the reliability of pIRIR225 dates and underestimation of quartz OSL ages. The study also suggests that Dawa Co experienced a significant highstand in the early Holocene.

Summary: Arid climate disasters cause significant losses and development pressures on the Mongolia Plateau, which is a sensitive and representative region in the transition zone between arid and semi-arid climates. The Chinese government's policies implemented since 1980 have had some impact on the livelihood activities of farmers and herdsmen households, but more measures are needed. This study constructs a research framework for disaster vulnerability assessment and proposes a model for assessing the vulnerability of farmers and herdsmen households to arid climate disasters. It identifies the main influencing factors on vulnerability and suggests a mixed livelihood model involving the government and farmers and herdsmen to promote active and planned adaptation behavior.

Summary: The ecosystem health risk assessment of lake basins is crucial for the sustainable development of ecosystems in arid regions. This study adopts a coupled model to calculate the Ecosystem Health Index (EHI) and finds that the basin's EHI has decreased from a healthy state to a sub-healthy state between 1990 and 2020. The decline in Driver and Impact health indices is identified as the primary reason for the decrease in EHI.

Summary: After conducting comprehensive research on stratigraphy, sedimentology, and geomorphology, it was found that the Sunite Deflation Basin is a giant shell-like deflation basin located between the Otindag Sandy Land and the Tunggur Platform. With an area of over 8000 km2 and a volume of -393 km3, it is the second largest deflation basin in the world and the largest in Asia. Preliminary estimates suggest that it releases about 216 km3 of dust, which can be deposited up to -5.8 meters thick in the downwind loess area near Chifeng in Northeast China.

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: The interaction between the East Asian summer monsoon and the mid-latitude Westerlies in the transition zone of the northern Tibetan Plateau has a significant impact on the moisture evolution in mid-latitude Asia. This study reveals that the precipitation variability of the Westerlies dominates the lake level changes in Toson Lake, in contrast to the records from the northeastern Tibetan Plateau and northern China. The results also indicate that the moisture transport to Central Asia is modulated by the see-saw of the North Atlantic Oscillation and the anticyclonic circulation over Mongolia, rather than directly influenced by the East Asian summer monsoon.

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.
