===Monitoring glacial changes over time===
PERMOS (The Swiss Permafrost Monitoring Network) is an operational monitoring service, and its main goal is to create long-term scientific documentation of the permafrost changes in the Swiss Alps. To accurately represent the current conditions of the Alps, the network records permafrost temperatures and thermal changes in boreholes, the bottom temperature of the snow cover, ground surface temperature, and the development of snow cover. The network additionally takes air photos periodically from selected areas. These monitoring strategies continue to develop as new research and data are recorded over time.<ref>PERMOS monitoring((www.permos.ch/downloads/permos00-02.pdf.))</ref> The glaciers in the Swiss Alps have lost around half their volume during the last 90–120 years.<ref>{{cite journal |last1=Huss |first1=M. |title=Extrapolating glacier mass balance to the mountain-range scale: the European Alps 1900–2100 |journal=[[The Cryosphere]] |date=6 July 2012 |volume=6 |issue=4 |pages=713–727 |doi=10.5194/tc-6-713-2012 |bibcode=2012TCry....6..713H |quote=Total ice volume change since 1900 is −96 ± 13 km3|doi-access=free }}</ref><ref>{{cite journal |last1=Mannerfelt |first1=Erik Schytt |last2=Dehecq |first2=Amaury |last3=Hugonnet |first3=Romain |last4=Hodel |first4=Elias |last5=Huss |first5=Matthias |last6=Bauder |first6=Andreas |last7=Farinotti |first7=Daniel |title=Halving of Swiss glacier volume since 1931 observed from terrestrial image photogrammetry |journal=[[The Cryosphere]] |date=22 August 2022 |volume=16 |issue=8 |pages=3249–3268 |doi=10.5194/tc-16-3249-2022 |bibcode=2022TCry...16.3249S |quote=This translates to a halving of glacier volume|doi-access=free }}</ref>
