Projected effects of temperature changes on the Italian Western Tauri glaciers (Eastern Alps)
ABSTRACT A linear model was used to investigate the behaviour of the Italian Western Tauri glaciers as a result of temperature changes projected for the 21st century. The model estimates the temperature variations once the glacier snout length variations are known and vice versa: it estimates the gl...
