Temperature-related impacts from anthropogenic climate change are likely to affect the county in several ways. Increased average temperatures, along with more frequent extreme heat days and waves, will likely exacerbate existing high temperatures in developed areas that experience the phenomenon known as the urban heat island effect (UHIE). In built-up areas, vegetation is sparse, and roofs and pavement dominate the landscape, absorbing and retaining heat during daytime hours and releasing heat at night. Other human activities that contribute to the UHIE include combustion-engine vehicles and air conditioning. To help curb the UHIE in developed areas, the County will need to incorporate “green” and “cool” infrastructure into new and existing development. Examples of green infrastructure include trees and climate-appropriate landscaping for increased shade and reduced surface area of pavement. Ventura County will also need to incorporate cool pavement and cool roofs in new and existing development while also planting more shade trees in parking lots.
