Over the last 12 years, Houston grew by 20%, or 300,000 inhabitants. During that time, the night time temperature increased about 0.8°C. Over a hundred-year period, that would translate to a whopping 7°C increase.
看看人口快速增长的城市，像德克萨斯州的休斯顿，我们会看到城市热岛效应的真正影响。在过去12年间，休斯顿的人口增长了20%，或者说30万居民。在这段时间内，夜间温度上升了大约0.8℃。照此推算，经过100年，温度就会惊人地上升7℃。
