Global temperatures are rising. This is especially felt in urban areas due to the urban heat island (UHI) effect, where temperatures can be 10oF (5.5oC) higher than the surrounding countryside. This phenomenon is due to several factors that combine to alter the local microclimate of an urban area. However, several techniques can be employed by landscape architects to help combat the local rise in temperatures, saving money, reducing global warming, and making a more pleasant environment to…

Extreme heat is the number-one weather-related cause of death in the United States, according to the Centers for Disease Control and Prevention, and extreme heat can also harm infrastructure as well as the overall economy. What if it were possible to make cities cooler—that is, actually lower urban temperatures to improve the quality of life—with more-resilient development?

Urban heat islands threaten our health, our ability to reduce our carbon output and the...

Heat islands are urban areas that can have higher temperatures than surrounding rural areas with more greenery. Heat islands are caused by several factors,…

Are you aware of heat islands and urban heat island effect? Learn about the heat Islands and its causes. Also appreciate construction materials which contribute to the heat island formation and learn how smog formation encapsulates green house gases. Usually, urban lands (cities) have a mean temperature 8 to 10 degrees more than the surrounding rural areas. This makes a temperature difference, thus creating the effect called a "heat island" or more specifically an "urban heat island." The…
