Short summary
Glaciers in the Karakoram are changing but older maps often miss small ice bodies and blur the edges where ice is covered by rock. We made a clearer map by combining detailed satellite images, height information, surface temperature, computer-assisted mapping, and careful human checking. The new map shows about 13,900 glaciers and reveals that much rock-covered ice is concentrated on a small number of very large glaciers. This work helps people better understand water, risk, and mountain change.

On 16 Dec 2024, a frozen Himalayan glacial lake burst following rockfalls, triggering an "ice tsunami" and flash flood—the first well-documented winter glacial lake outburst flood (GLOF). As warming destabilizes slopes and weakens ice, such winter floods may increase. We urge heightened public awareness and call for future GLOF risk assessments and early-warning systems to include lake-ice condition as a key monitoring parameter under safety protocols.

After a glacial lake outburst flood in 2020, Jinwu Glacier in southeastern Tibet lost contact with its lake. Using satellite images, we found that the glacier front slowed strongly after a delay, while higher parts changed less and likely shifted toward more compressed flow. These results show that sudden loss of lake influence can alter glacier dynamics and future evolution.

Glaciers that end in lakes are changing rapidly in the mountains of Asia. We created the first long-term record of these glaciers and their lakes from 1990 to 2022 by analyzing satellite images. Our results show that many glaciers are shrinking while their lakes are growing. These changes matter because they affect water supply, flood risks, and mountain landscapes. This dataset offers new knowledge to support research and planning for climate change impacts.

An integrated approach comprising a field survey, remote sensing, and hydrodynamic modeling was applied to investigate the Rijieco Glacial Lake Outburst Flood (GLOF) in 1991. The flood caused devastating ecological consequences, like sedimentation and the expansion of an inland lake, which has not yet recovered after three decades. The results help understand the ecological impacts of outburst floods on the Tibetan inland lake system and make future flood hazard assessments more robust.

This paper quantifies the thinning and surface mass balance of two neighbouring debris-covered glaciers in the southeastern Tibetan Plateau during different seasons, based on high spatio-temporal resolution UAV-derived (unpiloted aerial
vehicle) data and in situ observations. Through a comparison approach and high-precision results, we identify that the glacier dynamic and debris thickness are strongly related to the future fate of the debris-covered glaciers in this region.

In this study, first we generated inventories which allowed us to systematically detect glacier change patterns in the Karakoram range. We found that, by the 2020s, there were approximately 10 500 glaciers in the Karakoram mountains covering an area of 22 510.73 km2, of which ~ 10.2 % is covered by debris. During the past 30 years (from 1990 to 2020), the total glacier cover area in Karakoram remained relatively stable, with a slight increase in area of 23.5 km2.

The China–Pakistan Economic Corridor plays a vital role in foreign trade and faces threats from water shortage and water-related hazards. An up-to-date glacial lake dataset with critical parameters is basic for water resource and flood risk research, which is absent from the corridor. This study created a glacial lake dataset in 2020 from Landsat and Sentinel images from 1990–2000, using a threshold-based mapping method. Our dataset has the potential to be widely applied.

Ice cliffs are believed to be important contributors to the melt of debris-covered glaciers, but this has rarely been quantified as the cliffs can disappear or rapidly expand within a few weeks. We used photogrammetry techniques to quantify the weekly evolution and melt of four cliffs. We found that their behaviour and melt during the monsoon is strongly controlled by supraglacial debris, streams and ponds, thus providing valuable insights on the melt and evolution of debris-covered glaciers.

We present a new approach for modelling debris area and thickness evolution. We implement the module into a combined mass-balance ice-flow model, and we apply it using different climate scenarios to project the future evolution of all glaciers in High Mountain Asia. We show that glacier geometry, volume, and flow velocity evolve differently when modelling explicitly debris cover compared to glacier evolution without the debris-cover module, demonstrating the importance of accounting for debris.

The monsoon is important for the shrinking and growing of glaciers in the Himalaya during summer. We calculate the melt of seven glaciers in the region using a complex glacier melt model and weather data. We find that monsoonal weather affects glaciers that are covered with a layer of rocky debris and glaciers without such a layer in different ways. It is important to take so-called turbulent fluxes into account. This knowledge is vital for predicting the future of the Himalayan glaciers.

On 22 March 2021, a ~ 50 Mm 3 ice-rock avalanche occurred from 6500 m a.s.l. in the Sedongpu basin, southeastern Tibet. It caused temporary blockage of the Yarlung Tsangpo river, a major tributary of the Brahmaputra. We utilize field investigations, high-resolution satellite imagery, seismic records, and meteorological data to analyse the evolution of the 2021 event and its impact, discuss potential drivers, and briefly reflect on implications for the sustainable development of the region.

We characterized the multi-decadal geomorphic changes of a low-angle valley glacier in the East Kunlun Mountains and assessed the detachment hazard influence. The observations reveal a slow surge-like dynamic pattern of the glacier tongue. The maximum runout distances of two endmember avalanche scenarios were presented. This study provides a reference to evaluate the runout hazards of low-angle mountain glaciers prone to detachment.

Short summary
Slope failures exist in many paraglacial regions and are the main manifestation of the interaction between debris-covered glaciers and slopes. We mapped paraglacial slope failures (PSFs) along the Hailuogou Glacier (HLG), Mt. Gongga, southeastern Tibetan Plateau. We argue that the formation, evolution, and current status of these typical PSFs are generally related to glacier history and paraglacial geomorphological adjustments, and influenced by the fluctuation of climate conditions.
Slope failures exist in many paraglacial regions and are the main manifestation of the...
