Chilevisión – Cities that change the climate

Do cities modify the climate? Sure, then. Note that cities cover two point seven percent of the planet’s surface, but are home to more than half of the world’s population. In Latin America, that proportion increases to 75 percent and in Chile, to 80 percent. Cities not only emit eighty percent of greenhouse gases, but also impact hydrology, relief, flora, fauna, and also the climate. Thus arises the urban climate, a product of the Impe, of the soils, humidity decreases, the ability to absorb heat is lost, the parameters of temperature, circulation, and intensity of winds are modified, in short. The main characteristic of the urban climate is the heat island, that is to say the difference between the temperature of the city and its rural surroundings. In a city, the temperature can be between two and up to ten degrees higher than outside it. Now, within the city there are also differences, according to the presence or not of vegetation. An example is Santiago, huh? Expression of inequity in this matter. Because while, for example, Lo Espejo, Renca, El Bosque, the percentage of vegetation that covers parks and squares does not exceed twenty-seven percent, there are communes like Las Condes, and Providencia, in which the vegetation covers more than seventy. Anyway, it’s the urban climate, you know what else? I become better in the field. Yes, no stuff. I want to go home.
