The statement released Wednesday says the World Meteorological Organization identified July as the hottest month in more than 140 years of record-keeping.

The scientists say the atmosphere and Earth’s surface are warming at an unprecedented rate, and by midcentury temperatures in Iowa will exceed 90 degrees Fahrenheit for 67 days per year, compared with the average of 23 days in recent decades.

Peter Thorne, director of the University of Iowa Environmental Health Sciences Research Center, said adaptations will include expanded disaster preparedness, increased energy use, and curtailment of outdoor work and recreation during times of extreme heat.

The University of Iowa Center for Global and Regional Environmental Research has released annual climate statements since 2011. They are vetted by Iowa’s top experts and are intended to place climate change research into an Iowa-specific context and encourage preparedness.
