Urban Heat Island
城市热岛效应
The exponential growth of urban areas has produced what is called the “Urban Heat Island” effect. 城市化的发展导致“城市热岛效应”. The temperature in the air above Urban Heat Islands can be as much as 12°F hotter than surrounding suburbs. 城市中的气温明显高于外围郊区的气温. ¾ Higher air-conditioning costs & greater consumption of energy.空调&其它人工热源消耗 ¾ Excess heat & increase energy production ⇒ causing air pollution & impact on global warming. 过度的能源消耗造成大气污染 & 温室效应.
