Top Climate Change Risks: Storm, Heat

Learn how climate change is affecting people in Illinois.
Then, check your local risk for heat, storm, fire, drought, and flood through 2050.

Typical Risks for Someone in Illinois

Compared to people in the United States, people in Illinois will experience especially increased risks from storm and heat due to climate change over the next 30 years.

The ClimateCheck Risk Rating is a 1-100 score that measures historical risk and increased exposure to risk with climate change, compared to everywhere in the U.S. (lower 48 states). A rating of 100 means risk is the highest for the U.S., while 1 means the risk is the lowest of anywhere in the U.S. Even with a risk rating of 1, climate change has both localized and large-scale effects that impact everyone on Earth.

For fire, the bar estimates the middle 50% of buildings and middle 50% of land area. For heat, drought, and storm, the bars represent the middle 50% of the population.

Storm Risk in Illinois with Climate Change

To measure storm risk, we look at the amount of precipitation that falls in storms, and how many times this happens per year. A storm is based on the top 2% of rainiest days per year for a location. Our risk rating is based on the amount of precipitation historically and the relative increase compared to the rest of the United States.

Historically, Bloomington experienced an average of 1.7 inches of rain about 9 times per year. In 2050, it is projected to experience an average of 2.1 inches of rain about 22 times per year.

Historically, Springfield experienced an average of 1.8 inches of rain about 9 times per year. In 2050, it is projected to experience an average of 2.4 inches of rain about 19 times per year.

Heat Risk in Illinois with Climate Change

An extremely hot day in Illinois is about 92ºF. This is based on historical maximum temperatures on the top 2% of days in an average year.

The frequency of very hot days is increasing. On average, someone in Illinois will experience about 42 extremely hot days in 2050.
A typical person in the U.S. will experience about 43 extremely hot days in 2050.

How Can We Adapt to a Changing Climate?



Mitigating climate change—by eliminating our emissions into the atmosphere and reducing our strain on the environment—and adapting to our changing planet are both vital to our well-being.

Understand Risks

Your level of risk depends on your city's capacity to adapt. Look up information on your city's characteristics and how they relate to preparedness for climate change: ND-GAIN Urban Adaptation Assessment.

Protect Homes and Communities


Check our free report for tips on protecting your home from hazards.

Green infrastructure is a category of nature-based solutions increasing precipitation. Find resources for individuals and municipalities through the EPA's Soak Up the Rain initiative.

Planting trees and vegetation helps reduce extreme heat in urban environments. Cool Pavements can also help urban heat islands. Search the Heat Island Community Actions Database to see what some municipalities have been doing to reduce extreme heat risk.
