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 ...
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 ...
Microwave and other radio frequencies cause heating, and this can cause burns or eye damage if delivered in high intensity, [38] or hyperthermia as with any powerful heat source. Microwave ovens use this form of radiation, and have shielding to prevent it from leaking out and unintentionally heating nearby objects or people.
A new color-coded heat warning system relies on magenta to alert Americans to the most dangerous conditions they may see this summer. The National Weather Service and the Centers for Disease ...
In urban areas people are at an increased susceptibility to hyperthermia. This is due to a phenomenon called the urban heat island effect. [36] Since the 20th century in the United States, the north-central region (Ohio, Indiana, Illinois, Missouri, Iowa, and Nebraska) was the region with the highest morbidity resulting from hyperthermia.
An urban thermal plume describes rising air in the lower altitudes of the Earth's atmosphere caused by urban areas being warmer than surrounding areas. Over the past thirty years there has been increasing interest in what have been called urban heat islands (UHI), [1] but it is only since 2007 that thought has been given to the rising columns of warm air, or ‘thermal plumes’ that they produce.
The July 1995 Chicago heat wave led to 739 heat-related deaths in Chicago over a period of five days. [1] Most of the victims of the heat wave were elderly poor residents of the city, who did not have air conditioning , or had air conditioning but could not afford to turn it on, and did not open windows or sleep outside for fear of crime.

Increased urban land use and occupation alters the local thermal field resulting in the development of warmer regions known as urban heat islands (UHIs). [8] An urban heat island is a phenomenon where these surface temperature deviations and air in the lowest levels of the atmosphere are concentrated in urban areas and those immediately ...
