Urban environmental and social stresses Details

Question 1

Effects of urban areas on climate

Answer 1

-More intense storms(due to stronger convection above built up areas)

-Creation of “heat islands”(due to stronger heat retention and release as a result of fuel combustion in inner cities and absorption of heat by asphalt and concrete)
-Thicker cloud covers in summer(due to increased convection)
-Radiation fogs/smogs in winter(due to air pollution)
-Reduced visibility(due to industrial haze)

-Using public transport
-Using energy-efficient technologies(e.g. hybrid/electric cars)
