Hot Time in the City: Heat Waves

A UCLA study confirms what many city residents know first-hand to be true: the heat island effect can make cities uncomfortably hot. Conducted by geography professor Dennis Lettenmaier and published in the journal Environmental Research Letters, the study reveals that, since 1973, prolonged periods of extreme heat have affected cities across the globe. “You have heat being stored in buildings and in asphalt, concrete and other building materials, and they don’t cool down as quickly as they would outside of the urban area. This effect was likely exacerbated by decreasing wind in most of the urban areas,” said Lettenmaier.
