Understanding Urban Heat Islands

Consider the following passage:

In the exploration of climate change and its impact on urban areas, researchers have identified that cities are often heat islands, significantly warmer than their rural surroundings. This phenomenon occurs due to the extensive use of concrete and asphalt, which absorb and retain heat. As cities expand, they trap heat with their buildings, vehicles, and industrial activities, which exacerbates the effects of global warming. Furthermore, heightened temperatures can lead to a myriad of health concerns, including increased rates of respiratory illnesses and heat-related ailments. Urban planners are encouraged to incorporate green spaces and sustainable materials in their designs to mitigate these effects.
