Scientists from Arizona State University (USA) have just published a study in which they affirm that the custom of painting the roofs of houses white to combat the warming caused by the expansion of large cities modifies the regional hydroclimate, reducing rainfall.
The research, which has been released in Environmental Research Letters , reveals that although increasing the reflectivity of buildings with white roofs is an effective way to reduce the higher average temperatures caused by the growth of cities, combating the effect heat island In the cities, the rain regime is also modified , which could be detrimental. "The truly sustainable development will have to consider the impacts that extend beyond the average temperature", concludes Matei Georgescu, co-author of the work.
