Global-scale hydrological response to future glacier mass loss

Huss, Matthias ; Hock, Regine

In: Nature Climate Change, 2018, vol. 8, no. 2, p. 135–140

Worldwide glacier retreat and associated future runoff changes raise major concerns over the sustainability of global water resources1,2,3,4, but global-scale assessments of glacier decline and the resulting hydrological consequences are scarce5,6. Here we compute global glacier runoff changes for 56 large-scale glacierized drainage basins to 2100 and analyse the glacial impact on streamflow....

A new model for global glacier change and sea-level rise

Huss, Matthias ; Hock, Regine

In: Cryospheric Sciences, 2015, p. 54

The anticipated retreat of glaciers around the globe will pose far-reaching challenges to the management of fresh water resources and significantly contribute to sea-level rise within the coming decades. Here, we present a new model for calculating the twenty-first century mass changes of all glaciers on Earth outside the ice sheets. The Global Glacier Evolution Model (GloGEM) includes mass loss...

Variations in Alaska tidewater glacier frontal ablation, 1985–2013

McNabb, R. W. ; Hock, Regine ; Huss, Matthias

In: Journal of Geophysical Research: Earth Surface, 2015, vol. 120, no. 1, p. 2014JF003276

Our incomplete knowledge of the proportion of mass loss due to frontal ablation (the sum of ice loss through calving and submarine melt) from tidewater glaciers outside of the Greenland and Antarctic ice sheets has been cited as a major hindrance to accurate predictions of global sea level rise. We present a 28 year record (1985–2013) of frontal ablation for 27 Alaska tidewater glaciers...

Runaway thinning of the low-elevation Yakutat Glacier, Alaska, and its sensitivity to climate change

Trüssel, Barbara L. ; Truffer, Martin ; Hock, Regine ; Motyka, Roman J. ; Huss, Matthias ; Zhang, Jing

In: Journal of Glaciology, 2015, vol. 61, no. 225, p. 65 - 75

Lake-calving Yakutat Glacier in southeast Alaska, USA, is undergoing rapid thinning and terminus retreat. We use a simplified glacier model to evaluate its future mass loss. In a first step we compute glacier-wide mass change with a surface mass-balance model, and add a mass loss component due to ice flux through the calving front. We then use an empirical elevation change curve to adjust for...

100-year mass changes in the Swiss Alps linked to the Atlantic multidecadal oscillation

Huss, Matthias ; Hock, Regine ; Bauder, Andreas ; Funk, Martin

In: Geophysical Research Letters, 2010, vol. 37, p. L10501

Thirty new 100-year records of glacier surface mass balance, accumulation and melt in the Swiss Alps are presented. The time series are based on a comprehensive set of field data and distributed modeling and provide insights into the glacier-climate linkage. Considerable mass loss over the 20th century is evident for all glaciers, but rates differ strongly. Glacier mass loss shows multidecadal...
