From Midwest Flooding Risk Increases Due to Warming Atmosphere

How could the warming atmosphere's increased moisture risk affect Chicago?

Possible What happens if… A possibility worth considering, not a forecast.

Increased moisture risk may raise municipal costs for Chicago's public buildings The warming atmosphere increases moisture and heavy rainfall events across the Midwest, putting buildings in Chicago at risk of water damage and mold growth. This has already been observed in Chicago Public Schools (CPS), where schools like John H. Kinzie Elementary School required environmental testing and remediation after mold was discovered. The resulting damp conditions and mold exposure pose public health risks to students and staff, and the necessary proactive monitoring, repairs, and remediation efforts place a strain on municipal resources and operational continuity for Chicago.

The facts so far

As reported. Each one links to where it comes from.

  • Illinois had a 15% increase in rainfall between 1895 and 2019.chicagotribune.com
  • The heaviest 1% of rainfall events in the Midwest became 42% wetter from 1958 to 2016.chicagotribune.com
  • The ideal range for indoor humidity levels, according to the U.S. Environmental Protection Agency, is closer to 30%-50%.chicagotribune.com
  • The Chicago Teachers Union reported that six school buildings, plus Kinzie, have experienced mold since the beginning of the school year.chicagotribune.com

Why it matters

The stakes for Chicago involve maintaining safe and functional public infrastructure and protecting the health of its youngest residents. Mold exposure can cause short- and long-term health issues in children, including worsening asthma and respiratory infections. The need for proactive environmental inspections and remediation places a continuous financial and operational burden on the city's public services and school district.

This issue is part of a larger, documented trend across the Midwest. Scientists do not expect the problems posed by more intense rainfall to go away, and the region is expected to see future increases of about 40% by the end of the century in the extreme 1% of rainfall events. This trend affects various public and private entities across the region, including school districts and municipal facilities.

What we don't know yet

  • What level of funding is required for CPS to proactively manage moisture and mold across all its facilities?
  • How will Chicago Public Schools adapt its operational schedules to mitigate risks during periods of prolonged heat and high humidity?

What would change this answer

The city mandates stricter building codes regarding moisture and ventilation in public structures.This would increase the certainty of municipal investment in infrastructure upgrades, potentially mitigating future costs.
The frequency of extreme rainfall events decreases.The immediate pressure on school buildings and municipal resources related to water damage and mold would likely decrease.
