Phoenix Is Trying to Beat the Heat

Phoenix is trying to beat the heat by turning its black asphalt streets gray. This special sealing reflects, rather than absorbs, all that hot desert sun. Cities are warming at twice the global average because buildings and pavement absorb in trap so much heat. The city is creating 100 cool corridors, planting hundreds of trees whose shade can drop the ambian air tempe by 30 to forty degrees compared to full sun.
