Summary: This study evaluated bacterial diversity and community structure in glacial soil and meltwater runoff at the frontier of Baishui Glacier No.1 using high throughput sequencing. The results showed that bacterial diversity was higher in soil compared to water, with soil samples having a more similar taxonomic composition influenced by ecological parameters. The relative abundance of bacterial phyla varied greatly between soil and water samples, with Proteobacteria dominating in water runoff and Acidobacteria, Actinobacteria, and Bacteroidetes dominating in soil. Environmental factors played a significant role in determining bacterial community structures in this ecosystem.

Summary: The Baishui River Glacier No. 1 has been continuously retreating over the past 70 years, with both its area and reserves decreasing annually. The findings indicate a strong correlation between glacier retreat and climate change, highlighting the importance of monitoring glacier mass balance as a sensitive indicator of climate-glacier interactions.

Summary: This study collected continuous observational data from the Baishui River Glacier No.1 using an automated real-time monitoring platform, and analyzed the seasonal changes in glacier movement and surface mass balance. The results showed seasonal variations in glacier movement and surface mass balance, which were influenced by air temperature and snowfall.

Summary: The unprecedented COVID-19 outbreak had a significant impact on various aspects of the world. One major effect was the reduction of air pollutants in cities worldwide in 2020. This study analyzed snow pit samples from Urumqi Glacier No. 1 in Xinjiang, China and found a decrease in anthropogenically induced soluble ions in the snow between 2019 and 2020, while they increased from 2018 to 2019. Analysis of air pollutant concentrations in major cities and towns in Xinjiang showed that the decrease in NO2 concentration corresponded to mobility restrictions, while SO2, CO, and PM2.5 concentrations did not consistently change.

Summary: The dynamic response of glaciers to atmospheric changes varies spatially and temporally, influenced by factors such as hydrothermal conditions, geometric controls, and seasonal and spatial variations. The Baishui River Glacier No.1 has been shrinking continuously with decreasing velocities from 2012 to 2019, showing higher speeds during the monsoon period. Dynamic variability decreased towards the glacier terminus and increased towards the upper reaches along a longitudinal axis.

Summary: The melting behavior of glaciers on and around the Tibetan Plateau is strongly influenced by their albedo. This study investigated the Qiangtang No. 1 Glacier located in the central Tibetan Plateau during the melting seasons from 2013 to 2015. The research found that dust played a more significant role in the glacier melting than black carbon.

Summary: The study investigated the distribution of light-absorbing impurities (LAIs) in Urumqi Glacier No.1 and their impact on albedo reduction and radiative forcing. Results showed that black carbon (BC) was the main factor causing snow melting, while dust was the main factor accelerating glacier melt. LAIs accumulated at lower altitudes of the glacier, affecting the albedo and radiative forcing of different types of snow and ice surfaces.

Summary: This study investigated snow leopard prey preference in the Kangchenjunga Conservation Area of eastern Nepal, finding that snow leopards show a higher preference for domestic livestock over wild prey due to the smaller available biomass of wild prey in the region. Recommendations include improving livestock insurance, enhancing livestock guarding, building predator-proof corrals, engaging locals in snow leopard conservation efforts, and promoting ecotourism.

Summary: The study showed that in the Yulong Snow Mountain region, the concentrations of elements such as aluminum, manganese, iron, zinc, and arsenic were relatively high in snow, river water, and groundwater. River and lake water near human settlements were affected by anthropogenic activities, while groundwater around Mt. Yulong remains uncontaminated.

Summary: Glaciers in the Himalayan region are receding rapidly and releasing legacy pollutants, such as mercury. This study conducted continuous monitoring and sampling in the Rongbuk Glacier-fed basin and found that mercury concentrations were mainly influenced by suspended particulate matter and showed diurnal variations. The annual export fluxes of total mercury and methyl mercury were estimated, and it was noted that the export of mercury from meltwater runoff in the Himalayas may increase in the future.

Summary: This study explores the changes in the ice volumes of Urumqi Glacier No. 1 and its impact on glacier runoff. The results show that under different climate scenarios, the glacier's area and ice volume will continue to decline, with the east branch disappearing by the end of the century. Additionally, the runoff will increase and then decrease over time.

Summary: On September 5, 2022, a magnitude 6.8 earthquake occurred in Luding county, Sichuan province, China, causing changes in the movement of glaciers in the Mt. Gongga area. Using satellite data and radar technology, the study analyzed the preseismic and postseismic surface velocities of the glaciers. The results showed that the earthquake directly caused an increase in glacier flow velocity, which returned to a stable state after more than 70 days.

Summary: Samples of meltwater and snow from Mount Everest's Khumbu Glacier were found to contain forever chemicals known as PFAS, indicating high-altitude chemical contamination on the mountain. PFAS compounds were detected at various sampling sites on the mountain, suggesting a widespread presence and the need for further research on water quality in the Everest area and the glacier watershed.

Summary: This study presents the cold-season glacier surface energy balance (SEB) result at high altitudes on Mt. Qomolangma based on in-situ observation from October 2007 to January 2008. The results show that strong winds and deficient clouds during the observational period led to a substantial sensible heat transport toward the glacier surface and an increase in longwave radiative loss. The clouds' shading effect surpassed its greenhouse effect and resulted in a decrease in incident solar radiation.
