In Chelsea, cooling an urban heat island one block at a time
As cities increasingly face longer and more intense hot weather, some are undertaking efforts like the heat-fighting Cool Block project in Chelsea, Massachusetts. More shade-producing trees are being planted and dark asphalt and heat-reflecting concrete are being replaced by white or gray concrete or other materials that reduce heat emanating from sidewalks and roadways. White roof surfaces are being installed over darker surfaces that hold heat. Larger U.S. cities — including Phoenix, Philadelphia and New York — are making strides in developing “cool corridors” that use a variety of techniques to battle the urban heat-island effect. Experts like Fulton Schools Assistant Professor Ariane Middel, an urban climatologist, are advising communities on these efforts to help ensure sound science and engineering principles are guiding these endeavors.
