Europe is experiencing increasingly frequent and intense heatwaves, impacting millions. Despite record-breaking temperatures, air conditioning remains surprisingly uncommon in European homes. While approximately 90% of US homes have AC, Europe’s rate is closer to 20%. Most Europeans are relying on fans, ice packs, and cool showers to cope with the heat. Factors contributing to this disparity include building design prioritizing natural ventilation, higher energy costs, and cultural preferences. The situation raises questions about adapting infrastructure to address the growing threat of extreme heat events linked to climate change.
