Urban Heat Island Effect: European Cities Face Extreme Heat

As heatwaves grip Europe, the urban heat island (UHI) effect is making cities unbearably hot. Temperatures in cities can be up to 15°C higher than in rural areas.

Health Impacts: A study in Portugal showed an 18.9% increase in hospital admissions during heatwaves. The elderly and children are most vulnerable.

Causes: Asphalt and cement absorb and emit heat. Tall buildings and pollution exacerbate the effect.

Social Inequalities: Poorer areas have less green space and worse housing conditions, worsening the impacts.

Solutions: Green roofs, planting trees, and better water management can help. However, reducing emissions is essential.
