Materials to fight urban climate change

Local climate change and in particular, the urban heat island, is the more documented phenomenon of climate change. It deals with the development of higher ambient temperatures in the dense areas of cities suffering from high anthropogenic heat release, compared to the temperature of the surrounding suburban or rural areas. Actually, there are available measurements for about 400 cities around the world. Heat island exists at any latitude and may be present during the day or night period, depending on the local thermal balance.
