This is part of why we need to change the way we build our cities. Vast stretches of wide roads and massive parking lots soak up a lot of heat. Tram lines can have grass between the rails. Pedestrian paths can be built with lighter colors. Cycling pathes take up less space and allow for green space. Building up instead of out keeps cities smaller and more contained, even providing shade on streets.
Less asphalt also mean rainwater run off is less of an issue. Rain water collects dirt, garbage, salt, oils, tire/brake dust, and increases in temperature as it runs along hot road surfaces towards sewers. These all impact local streams and lakes by poisoning the water and disruprting natural temperature regulations (many eggs use water temperature to determine if it is time to hatch and if food will be available when they hatch).
