United States. NASA published a study that analyzes the impact of warming in the different states of the nation, in which it was found that cities with large buildings or waterproofed by asphalt generate higher temperatures than those with vegetation as the predominant element.
Asphalt cities record temperatures 1.9 degrees higher than those of vegetation. In the winter, the phenomenon, which is identified as a "heat wave", produces an increase of more than 1.5 degrees.
The US agency assures that the study is based on the land use component, ruling out that the results are based on greenhouse gas emissions.
Wikipedia defines the "heat island" effect as an urban situation, of heat accumulation by the immense mass of concrete, and other heat-absorbing materials; and atmospheric that occurs in situations of stability by the action of a thermal anticyclone.
The study was published in Environmental Research Letters, and also presents a report on how the effect of urban heat is regulated thanks to existing plants in urban areas.
