Various reports, data and graphics are available within the framework of the Swiss Climate Change Scenarios. This information and data form the basis for adaptation to climate change in Switzerland. They enable scientifically sound decisions to be made for climate adaptation and climate mitigation. This overview is intended to help users select the products and data that are most suitable for their purposes.

Climate CH2025 video
The video outlines the key messages of the current Swiss climate scenarios.
Climate CH2025 web atlas
The Climate CH2025 web atlas contains a wide range of graphics and related data. Climate variables (such as temperature) are available for measuring stations, major regions or for the whole of Switzerland.
Climate CH2025 scientific report
The scientific report describes the methods and results of Climate CH2025 in detail. It is aimed at researchers and is available in English here.
Climate CH2025 datasets
The available data sets from Climate CH2025 include daily time series of meteorological variables at stations (DAILY-LOCAL) and on a high-resolution 1 km grid (DAILY-GRIDDED). These large data sets are primarily intended for further processing by computer models. The data are accessible via the Open Government Data Portal.
Overview of past and future changes in weather and climate phenomena
This overview shows if and how climate variables such as temperature, precipitation and wind, as well as phenomena such as hail and fog, have changed in the past. In addition, possible future trends and reasons for existing uncertainties are explained.
Opening event of Climate CH2025
On 4 November 2025, the results of Climate CH2025 were presented at ETH Zurich. The recording of the presentations and the panel discussion are available on the C2SM website.
Overview of previous Swiss Climate Change Scenarios
Work on national climate scenarios for Switzerland began in the early 2000s. Since 2014, MeteoSwiss has had a mandate from the Federal Council to regularly produce up-to-date climate scenarios based on the latest scientific findings. The reports and data from the three previous climate scenarios can be found here.
