Extreme Heatwave Takes Toll on Swiss Infrastructure and Environment
The ongoing heatwave is causing widespread disruption across Switzerland, leading to rail infrastructure problems, forcing the River Aare to a new temperature record, and accelerating the melting of alpine glaciers.

Key Takeaways
- Switzerland is warming at twice the pace of the global average.
- More than 1,100 Swiss glaciers have disappeared completely since the early 1970s.
- Extreme heat causes steel rails to expand, risking track deformation and points failure.
