Summary: A surging glacier was discovered on the Zangser Kangri ice field in the Central Tibetan Plateau, with evidence showing the surge event started between late 2012 and early 2014. The glacier may have surged in the 1970s as well, and has maintained a slightly positive mass balance since 1999, potentially due to its location on the southern edge of mass balance anomaly on the Tibetan Plateau. The characteristics of relatively balanced mass condition, large size, and shallow slope may be associated with glacier surges in the Central and Northern Tibetan Plateau.

Summary: Photogrammetric reconstructions of the Aldegondabreen glacier on Svalbard using archival terrestrial photographs from 1910 and 1911 show a significant volume loss over the last century. The rate of volume loss remains relatively stable, but the rate of elevation change is increasing, indicating potential rapid disappearance of the glacier in the next few decades. If representative of the region, these findings suggest significant ice loss for low elevation glaciers in western Svalbard over the 1900s.

Summary: A long-series mass balance study of Laohugou Glacier No. 12 shows a continuous decline in glacier mass from 1980 to 2020, primarily due to accelerated melting caused by rising air temperature, with a significant impact from incoming shortwave radiation.

Summary: In recent decades, climate change has caused significant impacts on human life, such as global warming, glacier melting, extreme weather, and rising sea levels. Remote sensing technology has played a crucial role in studying and monitoring glaciers. This study analyzed 4817 literature works related to glacier mass balance based on remote sensing technology from 1990 to 2021, revealing the major countries, research institutions, hotspots, and frontiers in this field. The research findings provide valuable insights for future studies and highlight the importance of improving data quality and merging multiple methods for precise and long-term monitoring of glacier mass changes.

Summary: Using the SPHY model and LANDSAT satellite data, researchers reconstructed the runoff components and glacier mass balance in the Niyang River basin. The results showed that rainfall runoff was the dominant contributor to total runoff, followed by snowmelt runoff, glacier melt runoff, and baseflow. The NRB experienced a severe loss in glacier mass balance, with the northern region experiencing greater loss compared to the southern region.

Summary: This study examines the annual balance of eight alpine glaciers from 1961 to 2018 and finds that the glaciers have experienced a negative balance, with a more significant decrease in balance from 1991 to 2018. By improving the calculation method and considering May-September temperatures, the study accurately predicts the annual balance of the glaciers. The research also reveals that temperatures in the Alps have already increased by approximately 3 degrees Celsius since 1880, indicating a rapid shrinkage of the glaciers if temperatures continue to rise.

Summary: This study reveals that the mass balance of glaciers is highly dependent on elevation and exhibits vertical heterogeneity. The middle-elevation zone is identified as the sensitive zone for glacier mass balance, with a core region of gain and loss transformation. The cold phases of La Niña and North Atlantic Oscillation have a significant impact on the mass balance, causing loss in certain elevation intervals.

Summary: This paper analyzes the changes in glacier mass balance in the Tien Shan Mountains and its impact on regional water resources. The results show that the glacier mass balance is decreasing overall, influenced by rising temperatures and changes in precipitation. The contribution of glacier runoff to river runoff varies among rivers but shows an increasing trend.

Summary: This study assesses the glacier change status in Shyok basin, East Karakoram, finding that most glaciers are stable but the percentage of retreating glaciers has increased since 2000. Climatic studies also indicate a warming trend and decreased snowfall in the region. Overall, there is no evidence of a Karakoram or climatic anomaly in the Eastern parts of Karakoram.

Summary: This study introduces a physically-based model for the evolution of supraglacial debris in the Global Glacier Evolution Model, using the Caucasus as an example. The future evolution of glaciers in the region is assessed under different scenarios, highlighting the importance of limiting climate warming. The inclusion of debris cover in modeling improves the representation of glacier geometry locally.

Summary: This study uses a distributed coupled snowpack and ice surface energy and mass balance model to simulate the past and future climate change of the Italian glacier Furkeleferner. The results show that during the last Little Ice Age, the glacier's area was 2.8 times larger than today, indicating a 2.5K colder climate. Furthermore, a future temperature increase of +2K would result in the complete loss of the glacier.

Summary: This study analyzed the elevation change, ice flux divergence, and surface mass balance of glaciers in the West Kunlun Mountains. Results showed that the overall thickness change of the glacier in the region is almost zero, indicating a positive mass balance. The ice flux divergence was more significant on the ice tongue, and glacier surging was found to be the main reason for the decline of the two monitored glaciers.

Summary: Global glaciers are rapidly declining due to climate change, with the glaciers in Scandinavia and Iceland projected to lose a significant percentage of their volume by 2100. The model predicts losses between 67% and 90% for Scandinavian glaciers and between 43% and 85% for Icelandic glaciers under different emission scenarios. The model's sensitivity to past climate data products and future climate projections is found to be small.

Summary: This study examines glaciological mass-balance time series and climate descriptors using machine learning methods for clustering. The analysis reveals a coherent mass-balance trend and a latitudinal bias in monitoring programs. Glacier classification based on climate delivers three clusters, indicating climate-based regimes. Surface mass balance shows sensitivity to temperature, with fluctuations over time and a non-stationary behavior. These findings provide insights into glacier-climate relationships for observational and analytical strategies.
