Randomized trial assesses urban heat exposure in Swiss cities, highlighting rising risks with climate change.

The aim is to assess urban heat exposure in five Swiss cities under current and future climate scenarios.
Evaluated urban and rural heat exposure in Basel, Bern, Geneva, Lausanne, and Zurich.
Calculated temperature-based indices using the MeteoSwiss heat warning framework.
Analyzed future heat scenarios under three Global Warming Levels (GWLs).
Projected heat exposure will increase as global warming levels rise.
In a 3°C warmer world, cities are expected to experience three to four heatwaves per year.
Heatwaves in urban areas will last two to four days longer and reach higher warning levels than in rural areas.

Senoner et al. (2026) studied this question.
