Short summary
Coarse spatial resolutions reduce computational costs but poorly resolve complex topographies. Our simulations of an alpine ice field at 50 m to 2 km resolution show similar ice areas, yet much higher volumes at coarser resolutions. Resolutions of 300 m and finer accurately capture topographically constrained flow, while coarse resolutions flatten mountain slopes and peaks, affecting ice velocities, thickness, and thermal regimes which emphasizes the need for sufficiently high-resolution models.

Glaciers are key to understanding climate change, reflecting historical variability. Using glacier models on the computer, we reconstructed European Alps glaciers during the Little Ice Age, with a total ice volume of 283 ± 42 cubic kilometres. Also, the study determines equilibrium line altitudes (ELAs) for over 4000 glaciers, showing patterns influenced by temperature, precipitation, and solar radiation. After all, we introduce a new ELA correction approach based on solar incidence.

This study uses state-of-the-art computer simulations to better constrain the Greenland-Ice-Sheet's evolution over the past 24,000 years. By comparing model results with geological data, it reveals when and why the ice sheet grew and shrank, helping to improve future predictions of sea level rise and climate change.

Short summary
Electron spin resonance (ESR) thermochronometry can be used to determine rock temperature changes, which occur as rocks move towards Earth's surface in response to uplift and surface erosion. We use samples from a known-temperature borehole to validate the method, by constraining the thermal sensitivity of quartz ESR signals in the laboratory. Whilst we are able to recover temperature successfully with the Al-centre signals, the Ti-centre signals overestimate the borehole temperature.

Short summary
Terrestrial radar observations were used to investigate flow speed changes at Eqalorutsit Kangilliit Sermiat, a marine-terminating glacier in Greenland. The velocity varied on both daily and multi-day timescales, showing that the glacier speeds up markedly when meltwater or lake drainage increases basal water pressure. Usually speed changes move downstream with time towards the glacier front, but during multi-day speed-up events they start at the front and travel upstream.

Short summary
We estimate the thickness of a large glacier in the Himalaya, using recently available thickness measurements and a computational model which uses higher-order physics to match estimated thickness with satellite-observed velocity. Our velocity inversion achieves similar accuracy to leading thickness estimates, while thickness-constrained inversions show increased accuracy, but limited interpolative power. We make recommendations for future measurement locations and for choosing model parameters.

We present the testing and implementation of a calving framework for simulating the evolution of glacier fronts in grounded glacier tongues. The approach is coupled with a level set method to track changes in the glacier front over time and with an eigen-calving law that allows calving to respond to ice flow and stress conditions. The framework is evaluated using a synthetic glacier domain and, when applied to marine-terminating glaciers in Svalbard, reproduces observed calving front patterns.

Ice thickness near Greenland’s coast is still poorly measured, yet it is vital for predicting sea level rise. We flew a helicopter ice-penetrating radar over three outlet glaciers in southern Greenland and mapped the glacier bed where basal reflections were clear. We measured ice up to about 340 meters thick, with reliable penetration typically to about 300 meters, providing new constraints that can improve regional bed maps.

Short summary
As mountain glaciers are retreating, they are becoming increasingly debris-covered. We want to better understand how these glaciers respond to a changing climate. For this purpose, we present a new model that simulates transport of debris within and on the glacier. Our key findings are that short-term changes have a low impact, while long-term warming can lead to fast collapse of the glacier tongue after a phase of thinning, where the observed expansion and thickening of debris cover occurs.

Short summary
The properties of the permafrost ground depend on its temperature and composition. We used temperature data from 29 boreholes in Switzerland to study how heat moves through different types of mountain permafrost landforms, supporting a physically meaningful interpretation of thermal properties in terms of ice content, water saturation, and porosity. Understanding changes is important because they can affect how stable mountain slopes are and how easy it is to build things in mountain areas.

The OSLThermo and ESRThermo MATLAB libraries simulate how luminescence signals in feldspar and electron spin resonance signals in quartz minerals accumulate and fade over time, enabling reconstruction of recent rock cooling and surface temperature changes. By sharing these tools openly, we hope to promote collaboration, reproducibility, and broader use and development of these ultra-low-temperature thermochronology methods.

Sediments carried by rivers can damage infrastructure, affect ecosystems, and alter landscapes, yet it is often unclear where these sediments come from, especially in regions hidden beneath ice. We developed a simple way to trace their origins by shining X-rays on crushed rocks and sediments. The resulting X-ray signals act like fingerprints that can be matched to source rocks, revealing where sediments come from and allowing us to map erosion across landscapes.

The work shows detailed reconstructions of the glaciers in the Valsugana area (south-eastern Alps) during the Last Glacial Maximum (LGM) and is supported by robust evidence and new exposure datings. These are the first ages for the internal sector of the south-eastern Alps. Local glaciers not connected with the major ice network were used for the calculation of their equilibrium line altitude. This let us estimate LGM palaeoprecipitation and compare it to Alpine palaeoclimatological models.

Rock glaciers are bodies of frozen ground found in mountain regions. They move downslope and are mainly studied at the surface. Here, we analyze deformation data from a rock glacier borehole, providing continuous data for almost eight years. The data shows that the acceleration in the summer movement happens in the uppermost layer, while long-term movement is mostly occurring in a deeper layer. This is important for the interpretation of surface movements, which are used as climate indicators.

The extent to which Greenland's peripheral glaciers and ice caps current and future ice loss rates are unprecedented within the Holocene is poorly understood. This study connects the maximum ice extent of the Late Holocene with present and future glacier evolution in the Nuussuaq Peninsula (central western Greenland). By > 2050 glacier mass loss may have doubled in rate compared to the Late Holocene to the present, highlighting significant impacts of anthropogenic climate change.

We report flow speed variations near the front of a tidewater glacier in Greenland. Ice flow near the glacier front is crucial for the mass loss of the Greenland ice sheet, but in situ data are hard to obtain. Our unique in situ GPS data revealed fine details of short-term speed variations associated with melting, ocean tides, and rain. The results are important for understanding the response of tidewater glaciers to changing environments, such as warming, more frequent rain, and ice thinning.

Avalanches contribute to increasing the accumulation on mountain glaciers by redistributing snow from surrounding mountains slopes. Here we quantified the contribution of avalanches to the mass balance of Argentière Glacier in the French Alps, by combining satellite and field observations to model the glacier dynamics. We show that the contribution of avalanches locally increases the accumulation by 60–70 % and that accounting for this effect results in less ice loss by the end of the century.

We present a series of experiments conducted for the Last Glacial Maximum (~21 ka) over Europe using the regional climate Weather Research and Forecasting model (WRF) at convection-permitting resolutions. The model, with new developments better suited to paleo-studies, agrees well with pollen-based climate reconstructions. This agreement is improved when considering different sources of uncertainty. The effect of convection-permitting resolutions is also assessed.

Short summary
During glacial times in Switzerland, glaciers of the Alps excavated valleys in low-lying regions that were later filled with sediment or water. How glaciers eroded these valleys is not well understood because erosion occurred near ice margins where ice moved slowly and was present for short times. Erosion is linked to the speed of ice and to water flowing under it. Here we present a model that estimates the location of water channels beneath the ice and links these locations to zones of erosion.

This paper presents a two-dimensional subglacial sediment transport model that evolves a sediment layer in response to subglacial sediment transport conditions. The model captures sediment transport in supply- and transport-limited regimes across a glacier's bed and considers both the creation and transport of sediment. Model outputs show how the spatial distribution of sediment and water below a glacier can impact the glacier's discharge of sediment and erosion of bedrock.

Surface melt is a major factor driving glacier movement. Using satellite images, we have tracked the movements of 38 glaciers in the Pamirs over 7 years, capturing their responses to rapid meteorological changes with unprecedented resolution. We show that in spring, glacier accelerations propagate upglacier, while in autumn, they propagate downglacier – all resulting from changes in meltwater input. This provides critical insights into the interplay between surface melt and glacier movement.

We characterized short-lived episodes of ice mélange weakening (IMW) at the front of three major Greenland outlet glaciers. Through a continuous detection at the front of Kangerdlugssuaq Glacier during the June-to-September period from 2018 to 2021, we found that 87 % of the IMW episodes occurred prior to a large-scale calving event. Using a simple model for ice mélange motion, we further characterized the IMW process as self-sustained through the existence of an IMW–calving feedback.

Glacial and non-glacial processes have left a strong imprint on the landscape of the European Alps, but further research is needed to better understand their long-term effects. We apply a new technique combining two methods for bedrock surface dating to calculate post-glacier erosion rates next to a Swiss glacier. Interestingly, the results suggest non-glacial erosion rates are higher than previously thought, but glacial erosion remains the most influential on landscape evolution.

We developed a novel automated method for the detection and the quantification of ocean waves generated by glacier calving. This method was applied to data recorded with a terrestrial radar interferometer at Eqip Sermia, Greenland. Results show a high calving activity at the glacier front sector ending in deep water linked with more frequent meltwater plumes. This suggests that rising subglacial meltwater plumes strongly affect glacier calving in deep water, but weakly in shallow water.

The cooling climate of the last few million years leading into the ice ages has been linked to increasing erosion rates by glaciers. One of the ways to measure this is through mineral cooling ages. In this paper, we investigate potential bias in these data and the methods used to analyse them. We find that the data are not themselves biased but that appropriate methods must be used. Past studies have used appropriate methods and are sound in methodology.

Short summary
Debris-covered glaciers have a greater extent than their debris-free counterparts due to insulation from the debris cover. However, the transient response to climate change remains poorly understood. We use a numerical model that couples ice dynamics and debris transport and varies the climate signal. We find that debris cover delays the transient response, especially for the extent. However, adding cryokarst features near the terminus greatly enhances the response.

Editorial statement
The paper by Leger et al. presents a large-scale reconstruction of glacial sediment transport in the Alps, offering both novel insights and a versatile computational framework for investigating glacial processes at Quaternary time scales. The study's relevance spans paleo-glacier dynamics, sediment transport, and landscape evolution in alpine environments, making it highly valuable to geomorphologists, glacial geologists, and sedimentologists, as well as applied sectors. The developed model has the potential to unlock numerous key research questions relating to past and present glacier behavior.

Short summary
This study reconstructs for the first time the transport-pathways of sediments by glaciers during the last glaciation of the European Alps, 24000 years ago. This helps us understand how the European Alps were shaped by past glaciations and helps us better constrain the mechanisms of iceflow, glacier erosion and the movement of large sediment masses by ice. This breakthrough is achieved by coupling a smart particle-tracking algorithm to a machine-learning-enhanced glacier evolution model.
