The 24^th Swiss Climate Summer School is focusing on the theme “Climate Variability across Space and Time”. This theme has been chosen due to its paramount importance in terms of both scientific challenges and pressing societal concerns. Always with a focus on understanding system processes from observational and model perspectives, understanding sources of uncertainty, and implications for predictability and predictions, the specific topics include:

• Climate variability across time from the past to the present
• Climate variability across space from boundary layer processes to planetary scales
• Sources of uncertainty, seasonal to decadal predictability
• Implications for weather and climate predictions

This summer school addresses Early Career Researchers with a background in climate, engineering, environmental, economic, social and geosciences, among others. In addition to keynote lectures from internationally renowned experts and extensive time for discussions and poster sessions, two half days will be spent with workshops in smaller groups and hands-on practical work. An excursion will lead us to a scenic place with glaciers in the mountains. All Summer School participants are expected to present a poster of their research.
