Beirut temperature rises amid concrete heat

The article addresses the phenomenon of urban heat islands in Beirut, which leads to a significant rise in temperatures in the city during the summer. Scientifically, it is explained as a result of the transformation of green spaces and city trees into layers of cement and asphalt, which absorb sunlight and re-emit the heat, making the city hotter even at night. This rise in temperatures increases dependence on air conditioning, leads to higher electricity consumption and cooling costs for households and institutions, and poses serious health risks—particularly for children, the elderly, and outdoor workers. The reduction of green spaces causes the city to lose natural means of climate moderation, worsening the problem. The article emphasizes that addressing this challenge requires urban solutions such as expanding green areas, planting trees along streets, and using reflective materials that minimize heat absorption. These measures aim to restore environmental balance and reduce the city’s heat despite ongoing urban expansion.
