The freezing level in the tropical Andes, Peru: An indicator for present and future glacier extents: the freezing level in the tropical Andes

Schauwecker, Simone ; Rohrer, Mario ; Huggel, Christian ; Endries, Jason ; Montoya, Nilton ; Neukom, Raphael ; Perry, Baker ; Salzmann, Nadine ; Schwarb, Manfred ; Suarez, Wilson

In: Journal of Geophysical Research: Atmospheres, 2017, vol. 122, no. 10, p. 5172–5189

Along with air temperatures, the freezing level height (FLH) has risen over the last decades. The mass balance of tropical glaciers in Peru is highly sensitive to a rise in the FLH, mainly due to a decrease in accumulation and increase of energy for ablation caused by reduced albedo. Knowledge of future changes in the FLH is thus crucial to estimating changes in glacier extents. Since in situ...

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...
