Heatwaves increase across Europe
Heatwaves have become more common and severe in recent years. Cities experience higher temperatures than surrounding rural areas due to the urban heat island effect. This phenomenon makes daily life more difficult during summer months.
Role of trees in cooling cities
Trees create natural shade that lowers surface and air temperatures. Their leaves block sunlight and release moisture through transpiration. These processes help moderate local climates in built-up environments.
Current challenges in urban areas
Many European cities lack sufficient tree coverage. Paved surfaces and buildings absorb and retain heat. Without more vegetation, residents face greater health risks during extreme weather events.
Next steps for cities
Urban planners are considering increased tree planting programs. These efforts aim to expand shade coverage and improve resilience to heat. Additional data on long-term effectiveness is still needed.
