The International Symposium "The future of the glaciers: from the past to the next 100 years" was held in Torino (Italy) from 18 to 21 September, 2014 for celebrating the centenary of the Bulletin of the Italian Glaciological Committee. The "Bulletin", published as Geografia Fisica e Dinamica Quaternaria (GFDQ), is currently in its third series. The topics of the meeting were focused on glacier mass balance, monitoring and observation, glacier geophysics, glaciological hazard, climate driven glacial change, glacier hydrology, periglacial/permafrost processes, and snow processes. A selection of the papers presented at the Symposium is published in this volume. The centennial CGI activity represents the base of knowledge for prosecuting and improving Italian glaciological researches and for satisfying the increasing need for validated and reliable data for developing quantitative models of glaciers response to climatic warming.

In this study, we present a snapshot of Italian glaciers that outlines the hydrological years of 2006 and 2007 and was derived from the interpretation of high-resolution orthophotographs. The results are freely available and downloadable on the website of the Italian Glaciological Committee (http://www.glaciologia.it/). Considering that glacial resources are suffering the effects of an extreme degree of ongoing climate warming, glacier monitoring requires homogeneous and accurate contemporary surveying approaches to realize the effective management of multi-temporal glacier inventories in GIS environments. Furthermore, the diffuse and rapid withdrawal of glaciers requires the use of multi-temporal, repeatedly updated data acquired with the same instruments during the same time interval. In this work, the data collected were organized and processed using the orographic setting of the Alps (International Standardized Mountain Subdivision of the Alps, ISMSA-SOIUSA) rather than local and regional administrative boundaries within which glaciers are placed (regions and provinces). The conducted survey allowed us to evaluate the distribution of Italian glaciers (969 including the two small Apennine glacierets of Calderone in the Gran Sasso Massif), which covered an area of 387.4 km2 ± 2%. The most glaciated mountain group is the Ortles, with 134 glaciers covering an area of 76.5 km2, whereas the Alpi Marittime hosts only one small glacier (0,041 km2). New data, which until now have never been published in Italian inventories, refer to the extension of the glacial debris cover (> 46 km2, equivalent to 12% of the whole glaciated surface in 2006-2007). Debris cover was outlined on 614 glaciers, corresponding to 63% of all surveyed glacial units. The comparison of our data with those recorded in the first systematic glacier inventory of the Italian Alps (CGI 1959-1962) shows that in 2006- 2007, 181 glaciers were completely extinct, 470 glaciers remained unitary, and 171 bodies were fractionated to generate 243 new glaciers. As a consequence of recent glacial retreat and the induced fractionation of glacial bodies, the total number of glaciers increased (+ 147 glaciers), whereas the surface decreased by ca. 140 km2 (-27%). This work represents a breakthrough in the availability of glaciological data from the Italian Alps collected over a very short time period. This study will also satisfy the rising demand of open source availability of environmental data pertaining to mountainous regions. Source
