Lys Glacier Rapid Retreat, Italy

Lys Glacier drains south from Lyskamm in the Monta Rosa Group of Italy.  This glacier has a long history of observations that have indicated two short term advances in the 20th century 1912-21 and 1973-85 amidst a broader retreat.  The net change for the 1915-2004 interval was a 600 meter retreat (Smiraglia et al, 2006). They also noted a 10% area extent loss from 1975-2003, and since the glacier was …

Lobbia Glacier Retreat, Italy and World War I relic exposure

The summer of 2012 was a warm one in the Italian Alps. This has led to large losses in glacier volume and exceptional surface melting. One example of this has been the exposure via melting of a considerable amount of World War I relics. One location noted has been the Ago Di Nardis Glacier in the Trentino Mountains, where artillery ammunition is observed Image from Maffei Glauco / Trentino Italian …

Careser Glacier Breaking Up, Italy

The last year with a significant positive balance on the glacier was 1977, in the majority of years since 1980 the glacier has had no accumulation zone, which equates to an accumulation area ratio of zero (Carturan and Seppi, 2007). This translates to a glacier with no income of snow, but still plenty of losses via melting, which means the glacier cannot survive, and of course will drive the retreat …

Dosde Glacier, Italy retreat and separation

Dosdè Glacier in the Dosdè-Piazzi Group of the Italian Alps has been the focus of research by the University of Milan Department of Geography in the last decade to both chronicle its retreat, examine the causes, and evaluate the impacts and potential mitigation steps. In 1954 there was a Dosdè Est, Dosdè Centrale and Dosdè Ovest glaciers with respective areas of 1.2 and 0.8 and 0.9 square kilometers. By 2003 …
