A definition of urban heat island is: "The relative warmth of a city compared with surrounding rural areas." [14]: 2926 This relative warmth is caused by "heat trapping due to land use, the configuration and design of the built environment, including street layout and building size, the heat-absorbing properties of urban building materials, reduced ventilation, reduced greenery and water ...
The common blackbird (Turdus merula) may be the first example of actual speciation by urban evolution, due to the urban heat island and food abundance the urban blackbird has become non-migratory in urban areas. The birds also sing higher and at different times, and they breed earlier than their rural counterparts which leads to sexual ...

Within most U.S. cities, people of color are more likely to live in areas of high Surface Urban Heat Island Intensity than white people in the same cities. According to a study by climatologist Angel Hsu and colleagues, "the average person of color lives in a census tract with higher SUHI intensity than non-Hispanic whites in all but 6 of the ...
According to the U.S. Environmental Protection Agency, the urban heat island effect raises temperatures in areas with dense concentrations of pavement, buildings and other surfaces that retain heat.
Tokyo as an example of an urban heat island. Cities with constructed surfaces and devegetation are typically warmer than adjacent countryside. This phenomenon is known as urban heat islands. For example Tokyo’s average September temperature has increased by almost 2 °C. over 100 years. This differential would increase in the summer months.
About 41 million people in the U.S. live in urban heat islands, where city topography elevates temperatures by at least 8 degrees Fahrenheit, according to an analysis published Wednesday by ...
Urban heat islands are areas with man-made infrastructure that contribute to increased temperatures. [23] [40] The average temperature during the day in cities can be 18–27 degrees Fahrenheit higher than in the surrounding rural regions. [23] This is an example of one type of UHI, surface heat islands. Surface heat islands encompass the area ...
