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.

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.

On 16 August 2024, a cascading glacial lake outburst flood destroyed Thame Village, Nepal. An upstream glacial lake formed in the late 2000s overtopped triggering a downstream lake breach. Combined release of ~770,000 m³ with peak discharge >800 m³/s reached the village within 22–25 min. Losses exceeded 6.18 million USD. Small, rapidly evolving lakes pose often overlooked GLOF risks in a warming climate.

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.

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 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.

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.

Short summary
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 by about 44% and showed ice-cliff collapse and a short-lived advance. The study shows that sudden lake drainage can rapidly change glacier behaviour, with implications for how lake-terminating glaciers evolve after outburst floods.
