Summary: We studied the quality characteristics, chemical, mineral and isotope composition of nephrite, diopsidite and rodingite of the Nyrdvomenshor nephrite deposit in the Polar Urals. We used various techniques to analyze the samples and found that the nephrite was of substandard quality due to the presence of uvarovite and cracking. The formation of nephrite involved metamorphism, metasomatism, and the increased contribution of crustal fluid.

Summary: This article discusses the characteristics of gold-sulfide-quartz and gold-sulfide ore occurrences in the Manitanyrd region of the Polar Urals. The ore occurrences are found in NE-trending shear zones and share common geological structures. The mineral and chemical composition analysis reveals that they belong to the same mineral type, pyrite-arsenopyrite, with variable ratios. The formation of these occurrences can be attributed to a single hydrothermal system.

Summary: This study reveals that the expansion of Siberian larch into the tundra of the Polar Urals is spatially heterogeneous and influenced by environmental factors such as topography and snow cover. Trees tend to cluster in areas with convex surfaces and their locations are linked to snow distribution. As the climate warms, trees have expanded uphill and high snow depth areas have shifted upward, creating favorable conditions for recent tree growth.

Summary: Southern Andean glaciers have a significant impact on global sea-level rise. However, limited mass balance estimates prior to 2000 hinder our understanding of glacier mass changes over time. Using historical imagery and elevation data, we estimated the geodetic mass balance of the Northern Patagonian Icefield and the Southern Patagonian Icefield. Our findings indicate an acceleration of ice loss in the 21st century compared to the 1976/1979-2000 period, highlighting the importance of this study.

Summary: The 2007-19 glaciological mass balance series of Mera Glacier in the Everest Region, East Nepal, was reanalyzed using geodetic measurements. The results show that Mera Glacier has been losing mass at a rate of 0.41 meters per year, in general agreement with regional averages for the central Himalaya.

Summary: A study on the Kamchatka Peninsula in the Russian Far East reveals that glaciers have been retreating at an accelerated rate since the start of the 21st century. The analysis of satellite data shows that the average annual glacier mass change in the study period was -0.46 meters, with an acceleration in mass loss over time. This change is attributed to the rise in summer temperatures and a decline in winter precipitation in the region.

Summary: The diatom oxygen isotope composition from Lake Bolshoye Shchuchye in Arctic Russia is analyzed to understand the hydrological and climate dynamics. The study reveals that the diatom oxygen isotope record is associated with changes in summer insolation and Northern Hemisphere temperature. Short-term variations in the record are attributed to variations in snow melt and influx. This is the first study to identify such drastic centennial-scale hydrological changes in Holocene diatom oxygen isotopes.

Summary: The mineralization and sulfur isotopic composition of sulfides in gold-palladium ores in olivine clinopyroxenites from the Dzelyatyshor massif are controlled by the igneous layering of rocks, which affects the variability in mineral chemistry and ore component concentrations. The replacement of primary rock-forming minerals by secondary minerals at lower temperatures is a characteristic trend for pyroxenites, influencing the formation of native gold in parageneses with PGM and sulfides and the sulfur isotopic composition of sulfides.

Summary: The study presents new mass balance data of Austre Gronfjordbreen glacier, showing its sensitivity to climate change. Through measurements, reconstructions, and modeling, it was found that the glacier mass balance is highly sensitive to temperature changes, while the impact of precipitation changes is relatively small.

Summary: A study on the Muz Taw Glacier in the Sawir Mountains reveals significant surface lowering and negative geodetic mass changes over the past three years, mainly influenced by factors such as altitude and ice thickness. Further high-resolution surveys are necessary to gain insight into mass balance processes and mechanisms.

Summary: This study investigates the resilience of very small glaciers and ice patches in the southeastern European Alps under extreme snowfall events. The research findings show an increase of over 10% in ice volume on 14 ice bodies in the region from 2006 to 2018, primarily influenced by extreme winter snow accumulations in the 2000s. Despite expected summer warming in the future, modifying storm tracks and the increased frequency of extreme snowfall events during winter are crucial for ensuring the resilience of small glacial remnants in maritime alpine sectors.

Summary: Alternaria fungi dominate the grain microbiota in many regions of the world, with a high attention on the detection of mycotoxin-producing species. The study found a prevalence of DNA from Alternaria sect. Alternaria fungi over Alternaria sect. Infectoriae in wheat, and a frequent co-occurrence of at least two Alternaria mycotoxins in 62% of grain samples, with the combination of TEN and TeA being the most common. The levels of mycotoxins varied in different cereals and geographic regions, with a discussion on the impact of weather conditions on fungal contamination.

Summary: This study presented the first inventory of dust emission sources in Central Asia and northwestern China based on MODIS imagery data from 2003 to 2012. It found that dust point sources were unevenly distributed, with the highest frequency occurring in specific regions like the Taklimakan desert and the Aralkum. Dust emissions peaked in different seasons in different regions, such as in spring in China and eastern Kazakhstan, and in summer in Central Asia and western Kazakhstan.

Summary: Mountainous regions are globally important but monitoring is currently uneven. To address this gap, the development of a global reference network of long-term environmental and socioeconomic monitoring-mountain observatories is needed. Principles and ways of connecting existing initiatives, supporting emerging areas, and developing new mountain observatory networks have been proposed.

Summary: Recent studies show that climate change may exacerbate nitrogen and phosphorus loss from farms and farmland, leading to worsened freshwater eutrophication. This study investigates the relative importance of climate and land use drivers in nine study catchments in Europe and Turkey. The findings suggest that land use changes have a larger impact on nutrient concentrations and loads compared to climate change alone. However, in Beysehir Lake in Turkey, climate change poses a greater threat to the freshwater ecosystem than nutrient usage. Further research is needed to accurately simulate extreme flow and water quality and understand the response of aquatic ecosystems to reductions in N and P.

Summary: Dust is a crucial component of the Earth's climate system, impacting the global radiation budget and hydrological cycle. However, the interaction between aerosols, clouds, and energy budgets remains uncertain in climate models. Geological records of dust accumulation offer a potential way to study historical hydroclimate changes. This study focuses on the Arabian Peninsula and Western Asia, which are major contributors of dust to the atmosphere. By analyzing published data, the researchers create a map of dust source activation frequency (DSAF) and identify three preferential dust source areas. The findings provide a better understanding of the sources of continental dust and improve our knowledge of past rainfall climate in water-stressed regions.

Summary: Climate change is having a significant impact on mountain environments globally. Due to limited environmental data and lack of interdisciplinary consensus on observation priorities, the concept of Essential Mountain Climate Variables (EMCVs) has been proposed as a way to improve the utility of mountainous environmental data for scientific research and environmental decision-making.
