Summary: By reconstructing high-resolution local δO-18(sw) and sea surface temperature (SST) values in the southern Andaman Sea, this study reveals that the maximum Indian Ocean Monsoon (IOM) precipitation during the early Holocene migrated meridionally from the tropics to the subtropics before moving southward again after 5.0 ka. This shift is likely in response to the northward migration of the Intertropical Convergence Zone (ITCZ) and changes in El Nino Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD) activities.

Summary: This study examines the correlation between hydroclimatic change and vegetation history in the Xixi Basin, eastern China, during the late Pleistocene to early Holocene. The analysis reveals warm/dry and cold/wet climatic patterns that are consistent with palaeoclimatic records in the middle Yangtze region. These patterns are related to the migration of the Meiyu Front modulated by the El Nino-Southern Oscillation (ENSO) activities.

Summary: Summer rainfall in western North American deserts is vital for water budgets, sustaining ecosystems but also causing floods and erosion. By analyzing palaeoclimate records from the Grand Canyon, researchers found evidence of an intensification of the summer monsoon during the Early Holocene, leading to increased subsurface infiltration. This study highlights the potential impact of future precipitation changes on groundwater recharge in arid regions.

Summary: This study examines the response characteristics of East Asian summer monsoon (EASM) precipitation to abrupt climatic events during the early to middle Holocene transition. The results suggest that weak monsoon events recorded in North China were related to the 8.2 ka event in the North Atlantic region, possibly caused by the collapse of the Atlantic Meridional Overturning Circulation (AMOC) and the southward shift of the intertropical convergence zone (ITCZ).

Summary: This study investigates the effects of differences in climate base state on processes associated with the present-day South Asian monsoon simulations. The results show that the pattern of South Asian monsoon precipitation is similar in the two models, but the monsoon-ENSO teleconnections are weaker in E3SMv2 due to cooler tropical SSTs and lower ENSO amplitude.

Summary: This study investigates the development of peatlands in the Napahai wetland in southwestern China. The results show that peat formation occurred around 13.3 thousand years ago and continued until 7.2 thousand years ago, with a weakening trend in the Middle to Late Holocene. Comparison with other monsoon intensity and related hydroclimatic records suggests a correspondence between the development of Napahai peatland and changes in Indian summer monsoon intensity and summer insolation.

Summary: The deposition of organic carbon (OC) in terrestrial water bodies is an important carbon sink in the global carbon cycle, but the response mechanism of organic carbon accumulation rate (OCAR) to various climate processes is still unclear. In this study, a continuous sediment record from Beihai Wetland in southwest China was analyzed to establish the temporal variation of OCAR and evaluate its potential responses to climatic and environmental processes. The study found that the OCAR was relatively stable and low during the early Holocene due to the predominant contributions of detrital influx and low terrestrial organic matters. However, the intensification of the summer monsoon and increased regional precipitation resulted in extremely low OCAR in the mid-Holocene. The abrupt retreat of the Indian Summer Monsoon (ISM) led to the development of the current wetland from a lake-like system, and the extremely low sedimentary accumulation rate (SAR) contributed significantly to the identified low OCAR values. The wetland progressively developed following further retreat of the ISM, resulting in the highest OCAR levels during the Holocene. However, in the last 700 years, there was a rapid decline in OCAR due to intensified regional human activities. The increase in OCAR during the late Holocene was proposed to be a response to large-scale climate changes, specifically the variation of the ISM.

Summary: Aeolian deposits in central Alaska provide a well-preserved record of paleoenvironmental change since the deglacial period. These deposits also contain some of North America's oldest archaeological sites, making this region crucial for understanding human migration into high latitudes and the Americas. The study examines the influence of climate on early human groups and finds that temperature fluctuations were not the main driver of environmental or archaeological change over time.

Summary: The study shows that the wetland evolution in the Sanjiang Plain has been significantly influenced by the East Asian summer monsoon circulation. A transition from a shallow-water lake to a wetland occurred around 4.5 ka BP, coinciding with a decline in the strength of the monsoon. The wetland development over the past 4.5 ka BP has been closely linked to variations in the East Asian summer monsoon.

Summary: A wide-spread terrestrialization process in the Sanjiang Plain during the Holocene is reconstructed using high-resolution palynological and lithological data. The process began with the formation of a paleolake surrounded by broadleaved forests, followed by the initiation of a wetland dominated by Cyperaceae and Poaceae. Transition to a peatland occurred after the extinction of the paleolake, with alternating dry intervals and wet stages along with weakened and strengthened East Asian summer monsoon, respectively.

Summary: This study reconstructs the distribution, ages, and sedimentary process of fluvial terraces in a tectonically active area and monsoonal environment in the headwaters of the Yangtze River. It reveals the response of the river to differential tectonic and extreme climate events and suggests that tectonic activity controls the spatial scale and geomorphic characteristics of the terraces, while climate fluctuations determine valley filling, river incision, and terrace formation.

Summary: The Tibetan Plateau's landform is shaped by the interaction of surface erosion and tectonic uplift. The Lhasa River drainage underwent two rapid denudation stages in the late Oligocene-middle Miocene, both related to the uplift of the Gangdese Mountains and increased Asian summer monsoon precipitation. Subsequently, the denudation rate decreased rapidly, leading to a gradual decrease in relief in the central Gangdese region.

Summary: The study indicates that runoff and sediment flux in the Beiluo River on the Chinese Loess Plateau have been influenced by climate change and anthropogenic land cover changes since the mid-Holocene. Climate change is the dominant factor affecting runoff evolution, while land-use change has a more significant impact on sediment load, especially since 5000 BCE.

Summary: The seismic profiles in the southern Junggar foreland basin provide the first record of migrating conglomerate-sandstone transitions (CSTs) and allow for the quantification of their migration history. Linear regression analysis reveals that the CSTs migrated northward at different rates over time, likely due to variations in crustal shortening. Temporal deviations in the CST positions suggest secondary impacts from climatic change.

Summary: Despite recent advances in mapping and dating alluvial fans, quantifying surface features in remote sensing data remains a challenge. This study successfully quantified alluvial fan surface roughness using high-resolution remote sensing data, establishing a relation between backscatter intensity and in-situ age. The results show that the method can effectively distinguish alluvial fans and estimate their ages. Additionally, the study highlights the importance of insolation weathering in controlling surface roughness in the Dead Sea area.

Summary: This study examines extreme rainfall and flooding over the eastern Tibetan Plateau (TP) and establishes the link between large-scale synoptic environment, mesoscale process, and regional flood hydrology. The results show that the transitional pattern form Asian summer monsoons to midlatitude systems is the most frequent synoptic condition for flooding, and the interplay between complex terrains and moisture transport determines the contrasting flood characteristics. The study also highlights the interaction of complex terrains and nocturnal low level jets as the key mesoscale ingredients in dictating a pronounced diurnal cycle of extreme rainfall.

Summary: A magnitude 7.4 earthquake occurred in the northern Qinghai-Tibet Plateau on May 22, 2021. The earthquake was characterized by predominantly left-lateral strike-slip faulting, along with normal faulting within the Bayan Har Block. The surface rupture extended in a NWW direction for approximately 160 km along the Jiangcuo Fault, a poorly known young fault. Detailed mapping revealed various features on the surface rupture, including left-lateral offsets, tensional cracks, compressional mole tracks, and widespread sand liquefaction. The study suggests that the sub-faults, including the Jiangcuo Fault, could be part of the East Kunlun Fault system, serving as a broad and dispersive northern boundary of the Bayan Har Block.

Summary: The detailed evolution of valley-damming by glaciers on the southeastern Tibetan Plateau, including the large Gega paleolake, is reconstructed based on observed sediment sequences, and optically stimulated luminescence (OSL) dating. At least three river-blocking episodes and consequent phases of lacustrine development in the Gega and Jiedexiu dammed lakes have occurred since the local last glacial maximum (LGM). These events were likely triggered by changes in the extent and thickness of glaciers caused by rapid climatic changes.
