It's no wonder so many urbanites flee the cities on summer weekends. It really is hotter in the concrete jungle. Heat island effect refers to the ability of vast paved areas-city streets, rooftops, and sidewalks-to absorb and hold heat, making urban areas and the surrounding suburbs noticeably hotter than rural towns nearby. According to the Environmental Protection Agency (EPA), the temperature difference can be two to 10 degrees Fahrenheit. Not only uncomfortable, this phenomenon leads to greater energy demands, more air pollution, and illness related to heat and air quality.

No beach house? There are things that can be done about this sizzling problem, but most take community cooperation. Some ways to offset the heat island effect include installing vegetated green roofs or reflective, high-emissive cool roofs, and incorporating strategically located parks and trees in city planning.
