To make sound decisions in the face of climate change, government agencies, policymakers and private stakeholders require suitable information on local to regional scales. In Switzerland, development change scenarios is strongly linked adaptation strategy Confederation. The current for Switzerland CH2018 - released form six user-oriented products were result an intensive collaboration between academia administration under umbrella National Centre Climate Services (NCCS), accounting user needs stakeholder dialogues from beginning. A rigorous scientific concept ensured consistency throughout various analysis steps EURO-CORDEX projections a common procedure how extract robust results deal with associated uncertainties. main show that Switzerland's will dry summers, heavy precipitation, more hot days snow-scarce winters. Approximately half these changes could be alleviated by mid-century through strong global mitigation efforts. comprehensive communication rolled out distilled specific measures increase their uptake them actionable. narrative approach four fictitious persons was used communicate key messages general public. Three years after release, have proven indispensable basis users downstream applications. Potential extensions updates has been identified since then shape planning next scenario generation Switzerland.
