This study explores how rocks on glacier surfaces originating from rockfalls help measure erosion rates using a chemical marker called 10Be. By analyzing data from 31 glaciers we found that erosion rates vary widely but can be accurately estimated and reveal links to rock exposure, glacier movement, and climate effects. Comparing 10Be erosion rates to other exhumation rates shows cases of balance, slower erosion, or faster erosion, offering insights into the complex drivers of rockwall erosion.

Permafrost dynamics at Aiguille du Midi in the French Alps was investigated using Automated Electrical Resistivity Tomography (A-ERT) during four years. A-ERT reveals seasonal and multi-year permafrost changes. Temperatures estimated using resistivity measurements provide a good agreement with measured temperature in borehole in frozen zone. Variations in active layer thickness across different faces were observed, along with a slight decrease in permafrost resistivity suggesting warming.

Quantitative knowledge of water availability on high mountain rock slopes is very limited. We use a numerical model and field measurements to estimate the water balance at a steep rock wall site. We show that snowmelt is the main source of water at elevations >3600 m and that snowpack hydrology and sublimation are key factors. The new information presented here can be used to improve the understanding of thermal, hydrogeological, and mechanical processes on steep mountain rock slopes.

Climate change impacts all parts of the cryosphere but most importantly the smaller ice bodies like ice aprons (IAs). This study is the first attempt on a regional scale to assess the impacts of the changing climate on these small but very important ice bodies. Our study shows that IAs have consistently lost mass over the past decades. The effects of climate variables, particularly temperature and precipitation and topographic factors, were analysed on the loss of IA area.

More frequent rockfalls in high alpine environments due to climate change are a growing threat to mountaineers. This hazard is particularly important on the classic route up Mont Blanc. Our results show that rockfalls are most frequent during snowmelt periods and the warmest hours of the day, and that mountaineers do not adapt to the local rockfall hazard when planning their ascent. Disseminating the knowledge acquired from our study caused management measures to be implemented for the route.

We studied how water moves through fractured rock walls in a high mountain area in the Alps. Using sensors and tracers over two years, in a high-altitude site, we tracked where the water came from and when it flowed. Most of it came from melting snow, but some came from rain and older ice. The results show that heat and water flow can speed up the melting of frozen ground, which may affect mountain stability. This helps us understand how climate change influences these fragile environments.

The reactivity of local to regional hydrosystems to global changes remains understated in East African climate models. By reconstructing a chronicle of seasonal floods and droughts from a lacustrine sedimentary core, this paper highlights the impact of El Niño anomalies in the Awash River valley (Ethiopia). Studying regional hydrosystem feedbacks to global atmospheric anomalies is essential for better comprehending and mitigating the effects of global warming in extreme environments.

This paper is a multi-authored study documenting the possible existence of permafrost in permanently monitored rockslides in Norway for the first time by combining a multitude of field data, including geophysical surveys in rock walls. The paper discusses the possible role of thermal regime and rockslide movement, and it evaluates the possible impact of atmospheric warming on rockslide dynamics in Norwegian mountains.

Short summary
Ice aprons are little-known ice masses on steep Alpine rock faces. They are also paleo-environmental archives as their ice is several thousand years old. A special corer has been developed to sample the ice before analysing it.
