Future retreat of Great Aletsch Glacier

Jouvet, Guillaume ; Huss, Matthias

In: Journal of Glaciology, 2019, vol. 65, no. 253, p. 869–872

We model the future evolution of the largest glacier of the European Alps – Great Aletsch Glacier, Switzerland – during the 21st century. For that purpose we use a detailed three-dimensional model, which combines full Stokes ice dynamics and surface mass balance forced with the most recent climate projections (CH2018), as well as with climate data of the last decades. As a result, all...

GlacierMIP – A model intercomparison of global-scale glacier mass-balance models and projections

Hock, Regine ; Bliss, Andrew ; Marzeion, Ben ; Giesen, Rianne H. ; Hirabayashi, Yukiko ; Huss, Matthias ; Radić, Valentina ; Slangen, Aimée B. A.

In: Journal of Glaciology, 2019, vol. 65, no. 251, p. 453–467

Global-scale 21st-century glacier mass change projections from six published global glacier models are systematically compared as part of the Glacier Model Intercomparison Project. In total 214 projections of annual glacier mass and area forced by 25 General Circulation Models (GCMs) and four Representative Concentration Pathways (RCP) emission scenarios and aggregated into 19 glacier ...

Disappearing world heritage glaciers as a keystone of nature conservation in a changing climate

Bosson, J.‐B. ; Huss, Matthias ; Osipova, E.

In: Earth’s Future, 2019, vol. 7, no. 4, p. 469–479

Since 1972, the United Nations Educational, Scientific and Cultural Organization (UNESCO) World Heritage Convention aims to identify and protect sites of Outstanding Universal Value for future generations. However, growing impacts of climate change are of the utmost concern for the integrity of many sites. Here, we inventory the glaciers present in natural World Heritage sites for the first...

Calibrated ice thickness estimate for all glaciers in Austria

Helfricht, Kay ; Huss, Matthias ; Fischer, Andrea ; Otto, Jan-Christoph

In: Frontiers in Earth Science, 2019, vol. 7, p. -

Knowledge on ice thickness distribution and total ice volume is a prerequisite for computing future glacier change for both glaciological and hydrological applications. Various ice thickness estimation methods have been developed but regional differences in fundamental model parameters are substantial. Parameters calibrated with measured data at specific points in time and space can vary when...

Modelling the future evolution of glaciers in the European Alps under the EURO-CORDEX RCM ensemble

Zekollari, Harry ; Huss, Matthias ; Farinotti, Daniel

In: The Cryosphere, 2019, vol. 13, no. 4, p. 1125–1146

Glaciers in the European Alps play an important role in the hydrological cycle, act as a source for hydroelectricity and have a large touristic importance. The future evolution of these glaciers is driven by surface mass balance and ice flow processes, of which the latter is to date not included explicitly in regional glacier projections for the Alps. Here, we model the future evolution of...

A consensus estimate for the ice thickness distribution of all glaciers on Earth

Farinotti, Daniel ; Huss, Matthias ; Fürst, Johannes J. ; Landmann, Johannes ; Machguth, Horst ; Maussion, Fabien ; Pandit, Ankur

In: Nature Geoscience, 2019, vol. 12, no. 3, p. 168–173

Knowledge of the ice thickness distribution of the world’s glaciers is a fundamental prerequisite for a range of studies. Projections of future glacier change, estimates of the available freshwater resources or assessments of potential sea-level rise all need glacier ice thickness to be accurately constrained. Previous estimates of global glacier volumes are mostly based on scaling...

Analysis of temporal and spatial variations in hydrometeorological elements in the Yarkant River Basin, China

Wei, Ren-juan ; Peng, Liang ; Liang, Chuan ; Haemmig, Christoph ; Huss, Matthias ; Mu, Zhen-xia ; He, Ying

In: Journal of Water and Climate Change, 2019, vol. 10, no. 1, p. 167–180

Yarkant River is a tributary of Tarim River in China, and the basin lacks observational data. To investigate past climatic variations and predict future climate changes, precipitation, air temperature and runoff data from Kaqun hydrological station are analysed at monthly and seasonal scales using detrended fluctuation analysis (DFA). Results show that DFA scaling exponents of monthly...

Change detection of bare-ice albedo in the Swiss Alps

Naegeli, Kathrin ; Huss, Matthias ; Hoelzle, Martin

In: The Cryosphere, 2019, vol. 13, no. 1, p. 397–412

Albedo feedback is an important driver of glacier melt over bare-ice surfaces. Light- absorbing impurities strongly enhance glacier melt rates but their abundance, composition and variations in space and time are subject to considerable uncertainties and ongoing scientific debates. In this study, we assess the temporal evolution of shortwave broadband albedo derived from 15 end-of-summer...

The role of glacier retreat for Swiss hydropower production

Schaefli, Bettina ; Manso, Pedro ; Fischerc, Mauro ; Huss, Matthias ; Farinotti, Daniel

In: Renewable Energy, 2019, vol. 132, p. 615–627

High elevation or high latitude hydropower production (HP) strongly relies on water resources that are influenced by glacier melt and are thus highly sensitive to climate warming. Despite of the wide-spread glacier retreat since the development of HP infrastructure in the 20th century, little quantitative information is available about the role of glacier mass loss for HP. In this paper, we...
