Summary: Research has reconstructed the environmental equilibrium-line altitude (ELA) in the European Alps based on climate records and model projections. It is projected that the environmental ELA will continue to rise in the future, potentially leading to further glacier melting.

Summary: To reconstruct the past Arctic temperature variations, the authors screened 1116 tree-ring width and density records and applied four detrending functions. They selected 338-396 records that showed significant correlations with instrumental temperature data and combined them into a proxy record. The reconstruction explained 45-57% of the instrumental temperature variance since 1950, and the estimated Arctic warming amplitudes were consistent with temperature anomaly datasets.

Summary: Mountain ecosystems are undergoing significant changes in plant distribution due to human activities. The range dynamics of mountain plants show large variability, with some species expanding, shifting, or shrinking their range. A study of 1,479 species in the European Alps over the past 30 years found that red-listed species experienced a rapid range contraction and were unable to track climate warming. In contrast, aliens quickly expanded upslope while keeping their rear margins almost still. The findings suggest that conservation efforts should prioritize low-elevation areas where red-listed natives and aliens coexist.

Summary: Douglas-fir, a non-native tree species, has the potential to replace Norway spruce in Slovenian forests due to its better volume growth, wood quality, and tolerance to drought. It shows a higher radial growth response to climatic conditions and is more resistant to extreme drought events.

Summary: This work reviews the challenges and advancements in stable isotope investigation, highlighting cellulose as a preferred material for paleoclimatic studies and the difficulties in cellulose isotope analysis. Recent development of automated isotope analysis methods based on high temperature pyrolysis of cellulose shows promise, especially in analyzing the combined isotope delta C-13 and delta O-18. The role of delta H-2 values and new methods for hydrogen isotope analysis are still to be explored.

Summary: By utilizing satellite remote-sensing data and a deep-learning model, we have successfully simulated the evolution of glaciers in the European Alps and found that by 2050, the ice loss will exceed one-third of the current ice volume.

Summary: The mass budget of southern Patagonian glaciers is heavily affected by surface ablation, with an average point surface mass balance of -16.3 m water equivalent (w.e.) yr -1 between 1996 and 2020. The analysis found that the mean annual temperature has increased at a rate of 0.28C decade -1 over the study period. The largest contribution to the surface energy balance was the sensible heat flux.

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: The study shows widespread greening trends in the above-treeline ecosystems of the European Alps, influenced mainly by changes in land cover and biomass, with minimal impact from human disturbances. Spatial variability in greening at the regional scale is primarily influenced by slope orientation and local topography, with identified hotspots of sparse vegetation cover experiencing delayed snow melt and green-up dates in recent years. This ongoing greening primarily reflects the high responsiveness of sparsely vegetated ecosystems to improving habitat conditions above the treeline.

Summary: The study developed tree-ring width and C-13 chronologies for juniper trees in northwest Tajikistan, finding that precipitation significantly affects tree growth and isotope enrichment. The stable carbon isotopes in tree rings provide powerful evidence of climatic signals and can be used to investigate inter-annual variations in climate. The need for more detailed studies on tree growth responses to changing climate and tree-ring isotopes is highlighted to understand source water variations in the juniper tree forest.

Summary: European beech forests play a crucial role in providing ecosystem goods and services. The projected climate change of this century will significantly impact the vitality of these forests, especially in southeast Europe. By analyzing long-term monitoring data from Croatia, it was found that defoliation (DEF) showed an increasing trend from 1996 to 2017, while annual defoliation change (Delta DEF) did not show a significant trend. The results suggest that previous year drought has a strong influence on Delta DEF, while climate conditions have a weak or insignificant effect on DEF.

Summary: In the context of climate change, rock glaciers serve as important water resources due to ice melting and being water reservoirs. However, there is limited knowledge about the hydrology of these high-altitude accumulations. This study developed a conceptual model to understand the hydro-chemical processes in active rock glaciers. The study analyzed isotopic and physico-chemical characteristics of rock glacier outflows in the Swiss Alps, finding higher ion content and electrical conductivity in water from active rock glaciers compared to non-rock glacier sources.

Summary: Glacier mass loss in the southeastern Tibetan Plateau has accelerated due to increased warming, with the majority of the loss occurring during the monsoon months. Changes in precipitation amount and ratio have played a significant role in the mass loss, with increased solid precipitation in spring mitigating the loss. However, prolonged exposure to warmer temperatures has unsustainably intensified ice melt and catchment discharge, raising concerns for long-term water supply and hazards in the region.

Summary: The study suggests that the glacier advance in the European Alps during the Last Glacial Maximum was related to subsurface warming and driven by heavy snowfall late in the year, likely sourced from the Mediterranean Sea. These results indicate that heavy snowfall during autumn and early winter was the main factor influencing glacier growth during this period of the Last Glacial Maximum in the European Alps.

Summary: An integrated approach combining dendrometric and dendrogeomorphological analysis, geotechnical monitoring, and numerical modeling was used to study the surface displacements and triggering factors of a reactivating landslide in a forested DSGSD area in Valtellina, Italy. The study found that surface displacement signals spread from the upper to middle and lowest portions of the landslide, with correspondences between precipitation and tree-ring eccentricity. Topographic monitoring networks in 2016 revealed different displacement ranges in different portions of the landslide, with inclinometric probes confirming multiple sliding surfaces. A numerical stress-strain model provided comprehensive information on slope dynamics and controlling factors.

Summary: Landslide inventories are essential for extrapolating the spatial distribution of landslides, while the production of landslide hazard maps requires a deeper understanding of the temporal distribution of landslide activity. Historical maps and archive documents serve as important sources of data, but are often overlooked due to the need for interpretation across disciplines.

Summary: The study found that trees are highly sensitive to early summer temperatures, with recent temperature increase leading to a significant growth rate increase in trees. However, soils only show an incipient response to climate warming, likely due to their resilience towards changing environmental conditions and various factors influencing soil development.

Summary: The study analyzed tree-ring carbon and oxygen stable isotopes at three sites in Tuscany, Italy, to determine the extent to which they can serve as proxies for mass wasting processes. The results showed impairments in photosynthesis at the landslide site, with trees on the landslide exhibiting reduced photosynthetic capacity since 1993. However, since 2000, trees on the landslide showed trends of higher average maximum net photosynthesis during periods of landslide activity. The research confirms the possibility of reconstructing mass-wasting processes on forested slopes by considering physiological conditions recorded by stable isotopes in tree rings.
