Swiss climate change scenarios
The climate of Switzerland is changing. The Climate Scenarios for Switzerland CH2018 describe how our climate could change up to the middle of this century and beyond. «Dry summers», «Heavy precipitation», «More hot days», and «Snow-Scarce Winters» are some of the expected consequences of unchecked climate change for Switzerland. The potential impact of globald efforts to mitigate climate change – and the extent to which climate change would still affect Switzerland – is shown by the scenario «When climate change mitigation takes hold». The Climate Scenarios combine simulations that use the latest climate models with observations of the trends thus far, providing the most accurate picture to date of our country's future climate. The Climate Scenarios CH2018 confirm the previously known trends (CH2011, CH2007). However, they present a substantially more detailed picture of the future Swiss climate.

Als neues Produkt der aktuellen Schweizer Klimaszenarien CH2018 gibt es nun Faktenblätter zum Klimawandel in den Kantonen. Die Faktenblätter enthalten Informationen zur vergangenen Klimaentwicklung und zur Klimazukunft jedes einzelnen Schweizer Kantons. Sie dienen als Wegweiser und zentrale Informationsquelle zur kantonal einheitlichen Verwendung der Klimaszenarien CH2018 und sollen die Kantone bei der Planung von Klimaanpassungsmassnahmen unterstützen. Viele weitere Grafiken zu verschiedenen Emissionsszenarien, Zeitperioden und Variablen für jeden Kanton sind auf dem jetzt erweiterten CH2018-Webatlas interaktiv dargestellt und als Download verfügbar.
Image: MeteoSchweizDie zahlreichen direkten und indirekten Auswirkungen auf Mensch und Umwelt, die sich aus den Klimaszenarien CH2018 für die Schweiz ableiten lassen, sollen genauer erforscht werden. Personen aus Forschung, öffentlicher Hand und Privatwirtschaft definierten dazu offene Fragen und konkrete Bedürfnisse. Zusammengefasst ist dies alles im Bericht «CH-Impacts. Klimaszenarien CH2018 und daraus abgeleitete Folgen für die Schweiz – wie weiter? Grundlagenbericht des Vorprojekts», den ProClim, BAFU, ETHZ, MeteoSchweiz, NCCS, Universität Bern, Universität Zürich und WSL publiziert haben.

Image: NCCSThe CH2018 Climate Change Scenarios show where and how climate change affects Switzerland and what global climate change mitigation efforts can do about it. The expected consequences of unchecked climate change for Switzerland include more hot days, dry summers, heavy precipitation and winters with little snow. However, global efforts to mitigate climate change could curb future climate change.

Die globale Klimaänderung beeinflusst das Klima auf verschiedenen räumlichen Skalen. Resultate dazu wurden in diversen internationalen (IPCC 2007), europäischen (WHO 2008) und auch nationalen Studien (CH2011, North et al. 2007, OcCC 2008, AWEL 2007) publiziert. Wie dieser Bericht zeigt, ist die Klimaänderung auch im Kanton Graubünden feststellbar. Die Auswirkungen sind vielfältig und lassen sich unter anderem anhand verschiedener Klimagrössen wie Temperatur, Niederschlag und Schnee nachweisen.
The climate of Switzerland is changing. The Swiss Climate Change Scenarios CH2011 provide a new assessment of how this climate may change over the 21st century. They are based on new generations of climate models with higher resolution, improved statistical methods, and an account of all recent relevant studies as well as the assessments by the Intergovernmental Panel on Climate Change (IPCC).

This report describes possible impacts of climate change and vulnerabilities of the environment, economy and society in Switzerland due to the emission of greenhouse gases that are to be expected up to the year 2050. The possible impacts as well as their gravity are discussed for the following fields: land ecosystems, agriculture, water management, health, energy, tourism, buildings and infrastructure, urban Switzerland and insurances. This report is available in English (PDF only), German (PDF only) and French.
