Answer:
Scientists measure the temperatures of cities in order to determine the habitability of these cities and the way in which the climate will affect certain types of construction and ultimately the quality of life of its inhabitants.
Thus, for example, cities such as Chicago or Minneapolis, with winters with sub-zero temperatures, have construction systems that favor heat conservation, thus promoting greater energy savings when heating rooms. Instead, hot cities like Miami or San Diego, on the other hand, build their buildings seeking to insulate the heat from the buildings, in order to keep the rooms temperate.
