Summary: Glacial lake outburst floods (GLOFs) are a severe hazard in the Himalayas, primarily influenced by glacial lake expansion, volume increase, and climate change. A lack of systematic assessment and field surveys puts downstream residents at great risk. Comprehensive investigations are urgently needed to understand the relationships between lake expansion, dam conditions, and GLOF risk.

Summary: Glacier outburst floods pose a major hazard, but global analyses have shown a reduced frequency in recent decades. A Holocene palaeoflood record from the Rio Baker in Chile quantifies discharge and timing of glacier floods over millennial timescales, with highest flood frequencies occurring at 4.3-4.4 ka. The largest modern outburst flood recorded surpassed around 3810 m(3)/s in magnitude, indicating a decline in glacier flood magnitude over time.

Summary: The number and area of alpine lakes in Tien Shan are rapidly growing, mainly due to a warming climate and retreating glaciers. Glacial lakes continuously increased in size, while non-glacial lakes expanded intermittently. Proglacial lakes and extraglacial lakes showed the highest expansion rates among the four types of alpine lakes.

Summary: Glacier-associated hazards, particularly glacial lake outburst floods (GLOFs), pose a common and serious threat to high mountainous regions worldwide. This study focused on analyzing the dynamics and susceptibility of a selected glacial lake in the Satluj basin of the Western Himalayas using Landsat and Google earth imagery. The results show an increase in lake area and a high susceptibility index, indicating the potential for GLOFs. The study also assessed the impact on downstream areas and highlights the urgency to monitor and assess such lakes to mitigate the disastrous consequences.

Summary: The study revealed that in the Tama Koshi (Rongxer) basin, the total glacier area has decreased by 26.2 square kilometers over the past 56 years. From 2000 to 2016, glaciers experienced a continuous decrease in mass, with mean glacier surface elevation decreasing at a rate of -0.63 meters per year, and the mean glacier surface velocity slowing by approximately 25%.

Summary: Glacial lakes are rapidly growing in response to climate change and glacier retreat, posing a threat to mountain communities. Assessment of glacial lake development and flood impacts is crucial, as most glacial lakes are located at high elevations. Increasing lake size may lead to more frequent outbursts, causing socio-economic damages.

Summary: This study provides a detailed chronology of deglaciation and lake regression in the Cerro Benitez area near the Southern Patagonian Ice Field. The results show that the ice sheet locally thinned by at least 300 meters after a major glacial advance, and the ice-dammed lake experienced slow local regression followed by faster regression. The study also discusses the implications for megafaunal colonization in the area.

Summary: The Sikkim Himalayan glaciers and glacial lakes are experiencing the impact of climate change, leading to an increase in the total lake area, particularly in the Gurudongmar lake complex. Climate change and ongoing glacier retreat are the main factors contributing to the expansion of the lake areas, with changes in precipitation levels affecting the expansion velocity of the glacial lakes.

Summary: A comprehensive inventory of glacial lakes in the Indus River basin has been conducted using high-resolution Indian Remote Sensing satellite images, identifying 5335 glacial lakes with a total water spread area of 17395.03 +/- 1013.28 ha. The majority of lakes are smaller than 5 ha, situated at high altitudes of 4001-5000 m amsl, and concentrated in the Gilgit and Indus Upper subbasins.

Summary: This research investigates the impacts of climate change-induced Glacial Lake Outburst Floods (GLOFs) on agriculture in the Gilgit-Baltistan region of Pakistan. The study finds that farmers have suffered from the damage to their fertile land and crops caused by recent GLOFs, resulting in low crop yield and agricultural income. Current adaptation practices are inadequate to cope with the increasing climate risks, thus urgent support and interventions are needed to enhance the resilience of mountain communities to future GLOFs.

Summary: In this study, field surveys were conducted using UAV and USV technology, combined with satellite imagery data, to analyze the changes in glacial lake conditions before and after an integrated project in Jialong Co lake. The results showed that the engineering treatment effectively lowered the water level and improved the stability of the lake dam and moraine ridge, providing a scientific basis for glacial lake disaster mitigation measures.

Summary: Coastal dolphins and porpoises in Chilean Patagonia, such as the Chilean dolphin, the Peale's dolphin, and the Burmeister's porpoise, face a threat from rapid human development. To study these poorly known species, new tools are urgently needed. One potential method is medium-term monitoring, combining continuous recording with a long-term click detector. The combination of recording and detection devices proves to be a good alternative for studying these species in remote areas.

Summary: Glacier recession due to climate warming has led to the growth in size and number of glacial lakes, impacting water resources and glacier mass balance, as well as posing risks of glacial lake outburst floods. By creating a comprehensive inventory of glacial lakes in Peru, this study addresses knowledge gaps and provides reproducible methods for consistent monitoring in other mountainous regions. The inventory reveals that the majority of glacial lakes are detached from glaciers, with different dam types affecting lake size variations. This inventory serves as a crucial first step in understanding glacial lakes and assessing risks associated with glacial lake outburst floods.

Summary: This study examines GLOF events in glacierized areas of the Cordilleras of Peru and Bolivia using high-resolution satellite and aerial imagery, as well as documentary data. A total of 160 GLOF events from 151 individual sites are characterized and analyzed, tripling the number of previously reported events. The study provides important statistics on these events for regional GLOF hazard identification and assessment.

Summary: This study conducted year-round temperature and current measurements at depths of 58-392 m in Lago Grey, a 410 m deep glacial lake in Patagonia, to investigate the thermal structure and seasonal variations. The research revealed significant impacts of subglacial discharge on the lake's thermal condition, with the coldest temperatures observed below a depth of -100 m in mid-summer under the influence of glacial discharge. The data suggests that subglacial discharge and bathymetry play a key role in dictating mass loss and the retreat of lake-terminating glaciers.

Summary: This study compares supervised classification and manual digitization methods and finds that estimates of vegetation and bare sand areas in coastal sand dunes vary with image resolution and classification method. Supervised classification maps more extensive areas of bare sand and is more accurate than manual digitization, but has poor repeatability. Manual digitization has higher repeatability but relatively low agreement with field data. Increasing image resolution generally improves agreement with field data.

Summary: The aim of this study is to understand the present-day climatic control of the surface mass balance (SMB) of the Patagonian Icefields at interannual timescales, especially considering large-scale processes. We modeled the present-day glacioclimatic surface conditions for the southern Andes Cordillera and found that years of relatively high SMB are associated with the establishment of an anomalous low-pressure center near the Drake Passage, while years of relatively low SMB are associated with the opposite conditions. This study also highlights the Drake Passage as a key region that has the potential to influence the SMB variability of the Patagonian Icefields.
