Document Summary
5% of land cover in north american cities are parking spaces. Parking lots on a sunny day can increase ambient air temperature by up to 4 c. Increases air temps contributes to the uhi (urban heat island) phenomenon and intensity of heat waves. Uhi impacts health conditions of affected population and increases energy consumption in these areas. Uhi is a phenomenon of increases latent temperatures in urban areas compared to. Due to a higher density of low albedo (reflecting surface) surfaces, impervious surfaces, surrounding rural areas buildings, cars, and people. Short wave radiation cannot escape urban areas as easily and becomes trapped, increasing latent energy in the system. million in annual ecological services can be attributed to the urban forest in toronto. Improved air quality (reduction of pm and pollutants) Carbon sequestration (carbon is removed from the atmosphere and held in a solid form)
