Media Advisory: U of A experts from range of disciplines available as Arizona heat season arrives early
TUCSON, Ariz. — Tucson just recorded its warmest winter in history – zero frost days, breaking a record dating to 2018. This week, the city faces an extreme heat warning, with forecasts approaching what would be an all-time record high for the month of March. In 2023, extreme heat in Arizona claimed more than 900 lives and triggered more than 4,000 emergency department visits in a single year – more than hurricanes, floods and tornadoes combined.
The third annual Southern Arizona Heat Summit, held in February, brought together different stakeholders to work through how to shade streets, protect outdoor workers and keep vulnerable residents safe during power outages. That collaboration has already produced a heat action roadmap and a worker heat protection ordinance in Tucson.
With Arizona Heat Awareness Week and the start of the extreme heat season approaching, University of Arizona experts from a variety of disciplines are available to speak about extreme heat.
