Hitzeinseleffekte

Hitzeinseleffekte, often translated as urban heat island effects, describe the phenomenon where metropolitan areas are significantly warmer than their surrounding rural areas. This temperature difference is primarily caused by human activities and the built environment. Materials like concrete, asphalt, and buildings absorb and retain more solar radiation than natural landscapes with vegetation and soil. Additionally, waste heat generated by vehicles, industrial processes, and air conditioning systems contributes to the elevated temperatures. The lack of green spaces and water bodies in cities further exacerbates the effect by reducing natural cooling through evapotranspiration. Hitzeinseleffekte can lead to increased energy consumption for cooling, elevated air pollution levels as heat accelerates chemical reactions, and adverse health impacts for residents, particularly during heatwaves. Mitigation strategies include increasing urban greenery, implementing cool pavement and roofing materials, and improving building energy efficiency.
