Key messages

The 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.
