ANALYSIS OF VARIATIONS<br />
This chapter presents data and information collected during the 2008 surveys. The dynamic<br />
phase of each glacier is evaluated on the basis of the last available survey.<br />
Variations versus 2007<br />
All 47 glaciers, when compared with their 2007 data, are in a shrinking phase, with a net prevalence<br />
(80,8%) of strong and moderate decrements. The tendency of the last years is confirmed<br />
and 2008 is the 4th consecutive year in which 100% of sampled glaciers were reported in a<br />
decrement phase when compared against their previous survey.<br />
The statistical analysis highlights the negative peak of the Ortles–Cevedale Sector, with 4 strong<br />
decrements and 7 moderate decrements.<br />
