What extreme heat means for cities today
Europe’s cities are heating up fast, with urban areas becoming risk hotspots as heatwaves grow more frequent and intense. Across Europe, exposure to heatwaves jumped by 57% in just one decade, and without urgent adaptation, annual fatalities could rise from today’s 2,700 to as many as 50,000 by 2050. Urban heat islands can make cities up to 9°C warmer than surrounding areas, disproportionately affecting the elderly, low-income, and marginalized communities. Without urgent adaptation, rising urban temperatures could take a heavy toll on labour, GDP, and human life.
