Temperatures of 28°C in mid-September, a heatwave in June and new records for January: Switzerland is getting hotter and its climate is changing.

French-language Swiss public broadcaster, RTS, has comparedExternal link historical monthly temperatures of over 900 weather stations in Europe – and the results are striking.

In most stations, temperatures are currently getting closer to what was recorded in the 20th century at places further south. For example, Geneva is similar to northern Italy, Paris to Toulouse and London to the region around Bordeaux in France.

This is a logical conclusion, given that current average temperatures in Switzerland are almost three degrees higher than pre-industrial levels.

Faced with the speed of warming, flora is struggling to adapt.“Spruce trees have a lifespan of over 100 years. Temperatures are changing too quickly, which means that during their lifetime they will suffer, and their health will deteriorate,” says Rebetez. These trees could eventually become rare in Switzerland.
