Paris and Amsterdam Heatwaves Challenge Active Urban Lifestyles

A recent heatwave pushed temperatures above 35 °C in Paris and Amsterdam, testing the cities' bike‑friendly cultures. Despite the extreme heat, residents continued to jog, cycle and walk along the Seine and canals, but public transport systems struggled without air‑conditioning, prompting concerns that prolonged high temperatures could force commuters indoors and increase car use. Experts warn that if days of 38‑40 °C become common, the health risks of outdoor activity may outweigh the environmental benefits of walking and cycling, threatening the low‑carbon urban models both cities have built. The situation highlights the need for climate‑controlled public infrastructure to sustain active, low‑emission lifestyles in a warming climate.
