Summary: The Qinghai-Tibet Plateau plays a significant role in global climate change and is an ideal laboratory for studying long-term scale climate change. The Nangqian Basin, located in the central-eastern part of the plateau, has a long continuous sedimentary sequence that provides valuable information for researching climate evolution.

Summary: This study investigates the bio-physical effects of transport infrastructure on alpine ecosystems through a case study of the Qinghai-Tibet railway and highway. The results indicate diverse changes in greenness, wetness, dryness, and heat across road sections. However, there is no clear biophysical gradient with distance from the transport lines. The study emphasizes the need for attention to direct damages to soil and vegetation by transport construction and the habitat disruption, biodiversity change, and road kills by transport operation.

Summary: This study summarizes the influence of the Westerlies on the hydroclimate of the Central Qinghai-Tibet Plateau during the Holocene. By examining circulation indices and developing a Westerlies effect index (WEI), the study identifies two types of Westerlies effect and assesses potential circulation mechanisms. The findings suggest that the Westerlies played a more prominent role in delivering moisture to the region than previously thought.

Summary: In this study, a vegetation map with a spatial resolution of 30 m was generated for the central Qinghai-Tibet Plateau using the random forest classification approach. The validation showed that the overall accuracy and Kappa coefficient were both high, indicating the accuracy of the predicted vegetation map. The results can provide valuable information for further permafrost studies.

Summary: By developing a permafrost-tailored InSAR approach, the study reconstructs seasonal and long-term deformation of permafrost and finds that ground deformation is mainly controlled by factors such as slope angle, with warm and ice-rich permafrost regions being more vulnerable to extensive long-term subsidence. Additionally, different types of permafrost regions exhibit varying deformation patterns.

Summary: This study explores the expansion and changes in urban fringes in the remote Qinghai-Tibet Plateau, using net primary production as a comprehensive measure. The analysis reveals that the expansion of urban fringes is closely related to population and economic growth, with population playing a more consistent role, while the impact of economic growth decreases in later stages of urbanization.

Summary: The study presents the first long-term direct measurement of CO2 flux over Qinghai lake, revealing that the ice-covered period absorbs more CO2 from the atmosphere compared to the ice-free period. Saline lakes on the Qinghai-Tibet Plateau were found to be a significant sink for CO2, accounting for approximately one third of the net carbon sink in the terrestrial ecosystems.

Summary: The study of Late Mesozoic sodic mafic rocks in Central Tibet reveals enrichment in incompatible elements similar to oceanic island basalt, possibly due to a two-stage mantle evolution in the northern Qiangtang. This suggests the presence of an inherited carbonated lithospheric mantle beneath the northern Qiangtang prior to continental collision. The conclusions will help understand the Cenozoic geology of the multi-terrane collision system and uplift mechanism of the Tibetan Plateau.

Summary: Understanding the growth process and dynamic mechanism of the Qiangtang terrane is crucial for comprehending the geological evolution of Central Tibet. New fission track data obtained in this study, combined with previous research, reveal the cooling stages and tectonic events experienced by the Qiangtang terrane. The results show a northward younging trend during the Late Cretaceous, indicating northward exhumation. The data also suggest that the Qiangtang terrane underwent three main cooling stages before becoming a primitive plateau.

Summary: Regional climates have changed due to global warming, causing increased cirrus circulation and altered precipitation patterns. This study focuses on the causes of the midsummer drought in the Hoh Xil region, highlighting the importance of water vapor transport and circulation structure. The findings contribute to understanding the impact of climate change on the Qinghai-Tibet Plateau and the mechanisms of climate change under global warming.

Summary: This study focuses on the long-term tracking of thermal anomalies prior to earthquakes in the Central and Eastern Qinghai-Tibet Plateau. By conducting comprehensive statistical analysis on microwave brightness temperature (MBT) anomalies, it is found that an NE trending MBT increase stripe appears prior to a significant number of earthquakes in the study area. These anomalies are closely associated with seismic events occurring in certain blocks and are spatially consistent with extensional faults and geothermal fields. Possible source mechanisms of the anomalies are explored through rock loading microwave observation experiments. The study suggests that the anomalies are likely caused by intensified extrusion of the Indian plate and increased crustal stress, indicating their significant potential as earthquake precursors in the region.

Summary: Research on Miocene K-rich mafic rocks in the Lhasa Terrane of the southern Tibetan Plateau suggests that the mantle source of these rocks may have been enriched not only by the subduction of the Neo-Tethyan oceanic slab, but also by additional materials. This indicates a more complex geochemical evolution process than previously thought.

Summary: Using Independent Component Analysis (ICA) on Sentinel-1 InSAR measurements, the study successfully isolates seasonal deformation related to freeze-thaw processes. It reveals a linear increase in seasonal deformation, indicating a rise in Equivalent Water Thickness in the active layer. This method allows for quantification of amplitude variability over large scales in permafrost regions, providing new insights into water mass balance.

Summary: The study analyzed 2,511 published low-temperature thermochronometric ages as a proxy for erosion in Central Asia, revealing a relationship between younger cooling ages in areas of high precipitation and older ages in areas sheltered from precipitation. Climate plays a key role in enhancing erosion in areas with significant precipitation, while tectonically active but arid areas preserve a record of older erosion.

Summary: Quantifying and identifying the mechanisms behind variability in East Asian dust production and transport is crucial for understanding future dust emissions. Previous records have limitations due to sediment winnowing and input of non-dust material. High-resolution flux measurements from the North Pacific reveal higher glacial dust fluxes in the late Pliocene-early Pleistocene compared to the late Pleistocene-Holocene, suggesting a decrease in dust transport to the North Pacific over the Quaternary. The proposed driving mechanisms challenge existing interpretations and provide a roadmap for future research.
