1)Temperature differences between US cities and their surrounding rural areas: Albany - 22 degrees hotter Cleveland - 21 degrees hotter Tucson - 16 degrees hotter 2) I used Oklahoma City for this exercise. It is up to 15 degrees hotter in the city than in nearby rural areas. These two pictures show the reasons for this difference. The materials used to construct these buildings are made from heat absorbing substances such as asphalt, tar and concrete. These have a low albedo and high heat storing capacity. Thus they absorb heat and re-emit it and therefore maximize the UHI. 3)My policies measures focus on the three countermeasures against UHI: 1.Reduction of Anthropogenic heat emissions: *Subsidize efficiency energy consuming equipment, houses, buildings and urban areas *Facilitate the diffusion of low emission vehicles *Encourage use of public transportation *Encouraging the use of new energy. 2. Improvement of Urban Surface *Construction of urban parks *Promotion of tree-planting. 3.Improvement of urban structure: *Facilitate an urban heat emission treatment system. *Facilitate the development of less environmental burden cities. 4)No policies in my area of residence focus on reducing UHI due to the fact it is a very rural area .
