Urban Heat Island
An Urban Heat Island (UHI) is a phenomenon where urban areas experience higher temperatures than their rural surroundings. This occurs due to factors like buildings, roads, and concrete surfaces that absorb and retain heat more than natural landscapes. Additionally, reduced vegetation limits cooling through shade and evapotranspiration. As a result, cities can be several degrees warmer, especially at night. This increased temperature can affect energy consumption, air quality, and health. Mitigating UHI effects can involve planting trees, installing green roofs, and using reflective materials to help keep urban areas cooler.

An urban heat island (UHI) is a phenomenon where urban areas experience significantly higher temperatures than their rural surroundings. This occurs due to factors like dense buildings, concrete surfaces, and limited greenery, which absorb and retain heat. Additionally, human activities contribute to the heat through energy use and vehicles. As a result, cities can be several degrees warmer, especially at night, leading to discomfort, increased energy consumption for cooling, and heightened air pollution. Addressing UHI through green spaces and reflective materials can help mitigate these effects and improve urban livability.
