Urban Heat Island Effects

CAP climate researchers and social scientists revealed that neighborhood vulnerability to extreme heat depends on the amount and location of soil, paved surfaces, and vegetation. They found that minority, low-income, and elderly residents are at greatest risk for exposure to high heat.

High summer temperatures and an abundance of asphalt surfaces in the Central Arizona-Phoenix LTER study area create conditions for urban heat islands.
