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 ...
Such differences in spatial distribution leave certain, localized neighborhood at risk for micro urban heat islands. [9] Socially vulnerable groups are known to live in more densely populated areas with little vegetation that in turn have higher threats to heat exposure and often have adapting to and mitigation their exposure.

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 Big Apple is one of many cities around the world that is impacted by the urban heat island effect, a phenomenon where urban areas are warmer than their surrounding suburbs.
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 ...
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 ...
Climate shelters are a place of refuge for populations that seek shelter from extreme climate events exacerbated by the effects of urban heat islands. They include cooling centers, but also encompass parks and other outdoor spaces designed to provide a harbor for cooler temperatures than surrounding areas. Several cities have designed programs ...
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.
