Portrait of CC
The Cryospheric Commission (CC) monitoring networks was founded in 1893 as the glacier commission and is integrated within the Swiss Academy of Science (SCNAT) more precise within the Platform Geosciences. In relation to the changes caused by the incipient climate change it is the Commission’s task to observe the changes of the alpine cryosphere. Furthermore it is in charge of the supervision of all long-term national cryospheric monitoring networks. The commission works in close cooperation with the Swiss Snow, Ice and Permafrost Society (SIP).
Snow and ice embody fundamental environmental factors for the human being (climate, water supply, natural hazards, education and economy etc.). This is why the process of observing the alpine cryosphere is an important component within the overall monitoring of climate-related changes. Thanks to a resolution – which was requested by the Department of Home Affairs- of the Swiss Federal Council in 2008 it has been possible to safeguard the funding of long-term measurement series. Switzerland’s significant position in global climate observation is strengthened by this sustainable long-term funding back-up for various measuring series (especially of glaciers and permafrost). The funding is assured by the Global Climate Observing System (GCOS), MeteoSchweiz, the Federal Office for the Environment and the Swiss Academy of Sciences as well as the participating Universities and institutes for scientific research.

Die langjährigen Permafrostmessungen in den Schweizer Alpen zeigen für das hydrologische Jahr 2021 je nach Tiefe ein unterschiedliches Bild: Die kühleren Witterungsbedingungen führten zu einer Abnahme der Temperaturen nahe der Oberfläche sowie der Geschwindigkeit der Blockgletscher. In der Tiefe dagegen setzte sich die in den letzten zwei Jahrzehnten beobachtete Erwärmung fort. Dies berichtet das Schweizer Permafrost-Messnetz PERMOS.

The volume of Swiss glaciers decreased by almost 1 percent in 2021, in spite of plentiful snow in winter and a pretty cool summer. Despite considerable precipitation in summer, there was hardly any fresh snow in the Alps. All this shows the impact of climate change, reports the Cryospheric Commission (CC) of the Swiss Academy of Sciences.

Der Erwärmungstrend der letzten zwei Jahrzehnte im Permafrost in den Schweizer Alpen setzt sich auch im hydrologischen Jahr 2019/2020 fort und verstärkt sich. Dies zeigen mehr als 20 Jahre Messungen im Rahmen des Schweizer Permafrostmessnetzes PERMOS: Die Permafrosttemperaturen haben vielerorts Rekordwerte erreicht, ebenso die Mächtigkeit der Auftauschicht und die Geschwindigkeit der Blockgletscher.

The volume of Swiss glaciers continues to decline in summer 2020. Although it is not an extreme year, the decline remains significant and is drastically changing the image of the Alps. Since 1960, Swiss glaciers have lost so much water that Lake Constance could be filled with it, as reported by the Cryospheric Commission CC of the Swiss Academy of Sciences. At low altitudes, winter of 2019/20 was characterized by less snow than ever before.
