People continue to die from heat-related health issues in Arizona’s hotter regions, says Ariane Middel, an associate professor in the School of Computing and Augmented Intelligence, part of the Fulton Schools.  Middel, who uses various metrics to track extreme heat that go beyond simply air temperature, says more research is needed to understand the long-term impacts of extreme heat and air pollution. She points out that towns and cities often do not have sufficient resources to adequately shield people from high summer temperatures and says more cooperative connections between communities are needed to help provide better protection from extreme hot weather.
