Extreme heat isn’t a more serious challenge only for U.S. Sun Belt cites anymore. Cities in regions with typically cooler climates are now seeing temperatures increase more severely than in the past. The problem will have more dramatic impacts in those once more temperate regions because infrastructure in those areas isn’t designed to withstand the rising heat, says Mikhail Chester, a professor in the School of Sustainable Engineering and the Built Environment, part of the Fulton Schools. But an equally big threat from heat exposure is to people, he adds. Chester advocates for both more resilient infrastructure systems and also those that can diminish the consequences when heat leads to the failure of those systems.
