Cool Roofs Take on Heated Cities

The summer heat has peaked, and blistering temperatures are especially noticeable on scorching city streets. Known as the “urban heat island effect,” this phenomenon labels the way urban environments trap more heat than nearby suburban and rural areas. As a result, increased energy demands and air pollution are often anticipated, yet unavoidable.

“All the concrete and the blacktop warms up faster,” says Lauren Nash, a meteorologist with the National Weather Service. “So it keeps the city hotter and it stays hotter longer.”
