Pellicciotti, F., J. Helbing, A. Rivera, V. Favier, J. Corripio, J. Araos, J. Sicart, M Carenzo (2008) : "A study of the energy balance and melt regime on Juncal Norte Glacier, semi-arid Andes of central Chile, using melt models of different complexity" Hydrological Processes , 22, 3980 - 3997.

We use meteorological data from two automatic weather stations (AWS) on Juncal Norte Glacier, central Chile, to investigate theglacier–climate interaction and to test ablation models of different complexity. The semi-arid Central Andes are characterized by dry summers, with precipitation close to...


Rivera, A., F. Bown, C. Acuña, F. Ordenes (2008) : "Chilean glaciers as indicators of climate change" Terra Glacialis, 11, 193-207.

This work presents a summary of Chile’s present glacial environment and its most significant recent variations. Though the behaviour of some glaciers may be driven by non-climatic factors, the majority of them experienced a linear shrinkage and a generalized thinning as a result of both an increa...

Volcán Villarrica (39º25' 12" S, 71º56'27" W; 2847ma.s.l.) is an active ice-capped volcano located in the Chilean lake district. The surface energy balance and glacier frontal variations have been monitored for several years, using automatic weather stations and satellite imagery. In recent field...


Bown, F., A. Rivera & C. Acuña (2008) : "Recent glaciers variations at the Aconcagua basin, central Chilean Andes" Annals of Glaciology, 48, 43-48.

The majority of glaciers in central Chile have receded in recent decades, from >50m to only a few meters per year, mainly in response to an increase in the 0°C isotherm altitude. The Aconcagua river basin (33° S) is one of the major glaciated basins in central Chile, with 121km2 of ice in ...

Darkening Peaks: Glacier Retreat, Science and Society, University of California Press, USA, 126-135.

The Central Dry Andes form a high mountain barrier dividing Chile and Argentina between around latitude 31º and 35º S. They run north - south, reaching the highest elevations in the Southern Hemisphere: Aconcagua is 6,954 m a.s.l., while many other peaks rise over 6,000 m. Their slopes descend ab...

Part I: Global overview and outlook. Part II: Glacier changes around the world" In: UNEP: Global outlook for ice & snow, 115 - 152.

Glaciers and ice caps reached their Holocene (the past 10 000 years) maximum extent in most mountain ranges throughout the world towards the end of the Little Ice Age, between the 17th and mid-19th century. Over the past hundred years a trend of dramatic shrinking is apparent over the entire glob...
