This week’s On The Radio segment discusses how humidity has increased significantly during all seasons in all parts of Iowa since 1971.
Transcript: Humidity in the state of Iowa has increased significantly since 1971, according to the 2017 Iowa Climate Statement released last month.
This is the Iowa Environmental Focus.
Absolute humidity, usually measured by dew point temperature, has increased significantly in all parts of Iowa during all seasons. The largest increase was found in Dubuque with a 23 percent increase in springtime humidity from 1971 to 2017.
The statement’s lead co-authors Gene Takle, director of Iowa State’s Climate Science Program and professor of geological & atmospheric sciences at ISU, and Betsy Stone, associate professor of chemical and biochemical engineering at the University of Iowa, warned that increasing humidity makes conditions more favorable for increased rainfall, extreme rain events, mold and mosquitoes.
High humidity also presents health concerns for Iowans. More humid air along with rising temperatures can make conditions dangerous for manual laborers and individuals sensitive to heat exhaustion and heat stroke.
Titled, It’s Not Just the Heat, It’s the Humidity!, the statement ends with a call for Iowans to do more to mitigate the effects of climate change through improving energy efficiency, cutting emissions and advancing renewable energies.
