Warmer winters and a hotter Gulf of Mexico could be contributing to more tornadoes in Illinois, experts say
Illinois saw more tornadoes than any other state in 2023. Byron Hurley experienced that reality firsthand after three tornadoes touched down near his Chatham home in central Illinois last year.
“My house got hit on May 7. May 14 was a nasty supercell that hit Chatham,” Hurley said. “We also got some large hail on July 23. I rode that storm out in my car, taking cover at a drop-off area at a church just outside Chatham.”
According to Matthew Elliott, a meteorologist at the National Oceanic and Atmospheric Administration, Illinois experienced 118 tornadoes last year — the third most in its history. The numbers have not yet been finalized, Elliott said, but are unlikely to change.
The number of tornadoes in any state fluctuates significantly from year to year, said Jeff Frame, a professor of climate, meteorology and atmospheric sciences at the University of Illinois. According to Frame, the biggest component is the state’s number of “outbreaks.”
The Glossary of Meteorology, published in 2000, describes a tornado outbreak as multiple tornado occurrences caused by the same weather event.
The third biggest tornado outbreak on record in Illinois occurred March 31, 2023, with 36 tornadoes in one day. The second largest outbreak was 50 years ago in 1974. Frame said most years with high numbers of tornadoes see at least one tornado outbreak.
“Weather patterns in 2022 were not conducive to a lot of thunderstorms and tornadoes,” Frame said. “But in 2023, they were helped along by a couple of big events, starting with a large tornado outbreak across the U.S.”
The 2023 numbers were a significant increase from the 34 tornadoes recorded in Illinois in 2022. Nationwide, NOAA preliminarily confirmed 1,269 tornadoes in 2023.
Studies have also found climate change may be affecting tornado patterns. Victor Gensini, a professor at Northern Illinois University, said climate change can affect the conditions necessary to create tornadoes.
Tornadoes need instability –– warm moist air near the ground with cooler temperatures higher up –– and wind shear –– a change in wind speed or direction –– to form. Instability is more potent in the warm seasons, and shear is usually stronger in the winter.

As winters get warmer, Gensini said, there can be more instability and more shear –– leading to more winter tornadoes.
“It kind of has been a good example of what to expect with a warming climate with a much warmer winter, a much earlier start to spring, in a much faster start to tornado season,” Gensini said. “But we’re not sure if that’s a climate change signal or if that’s a signal of just weather or climate variability.”
According to Elliott, data has been inconsistent on the impact of climate change on tornadoes. But, he said, the times of year and the locations of tornadoes seem to be changing.
Walker Ashley, a professor of Earth, atmosphere and environment at Northern Illinois University, said increasing temperatures in the Gulf of Mexico may be affecting the number of tornadoes in states to its north –– including Illinois.
A hotter Gulf increases low-level moisture, which creates conditions ripe for tornadoes, Ashley said
“If the Gulf of Mexico is heating up under climate change, and we’ve seen it’s running hot, that increases your moisture and your instability,” Ashley said. “It makes sense the eastern part of the United States would heat up.”
Still, researchers cautioned against holding climate change entirely responsible for changing weather patterns in Illinois.
Technologies used to detect and predict tornadoes have adapted significantly over the last few decades, and are likely to have affected the number of tornadoes observed and recorded in Illinois –– especially since the state’s tornadoes tend to be low in intensity.
According to the National Weather Service, nearly 37% of tornadoes in northern Illinois from 1950 to 2017 were EF0 — the lowest intensity a tornado can be. Only 2% were classified as “violent.”
Out of the 22 days with tornado activity in 2023, four days caused injuries, two days saw property damage, and there were no days with crop damage, according to NOAA.

Hurley said the tornadoes that passed by his home in Chatham only caused tree damage. A conservationist who does storm chasing in his free time, Hurley said he followed multiple other tornadoes in Illinois last year, including one that started near Loami, 10 miles west of Chatham, on Aug. 6.
“I saw the beginning. … I had a great view of the wall cloud and bowl funnel near Loami but only got to see it briefly before falling too far behind,” Hurley said. “On Aug. 6, I got hailed on in Taylorville as well. It was a wild year, that’s for sure.”
Taylorville is about 30 miles southwest of Chatham.
Frame added that metropolitan areas throughout Illinois have also expanded in the past couple of decades. While lower-level tornadoes in rural areas may have gone undetected in the past, cellphones and population sprawl make them harder to miss in the 21st century.
“What we’re able to do is detect a lot more of these tornadoes with more spotters, better reporting technology, cellphones and internet, and better radar technology,” Frame said. “In 1960 you’re just never going to see those reports, because the technology and the infrastructure wasn’t there.”
While experts remain conflicted about the impacts of climate change on the number of tornadoes, they said Illinois residents should remain on high alert.
“It’s been an active year,” Gensini said. “I think we all need to be anticipating more of these tornado disasters. And that’s regardless of what’s happening with the frequency of climate change. Climate change is playing a role, an important role, but it’s not the only role.”

Bears stadium deal should not include lawmaker perks or raise property taxes
Publicly funded stadium deals can involve questionable incentives for politicians. The megaprojects bill in Illinois would drive up neighbors’ property taxes.
Any deal between Illinois and the Chicago Bears for a new stadium must avoid giveaways to lawmakers and property tax increases for others.
The Bears own the former Arlington Park Racecourse in Arlington Heights and have said they’re also considering Northwest Indiana for a stadium development. A bill in the Illinois General Assembly would offer property tax breaks to such “megaprojects.”
Agreements for publicly funded stadiums in other cities often have included luxury suites and free tickets for lawmakers. Local officials in Kansas City have been criticized for getting access to tickets and suites during ongoing stadium negotiations. Officials in Arizona have repeatedly used free access to publicly funded stadiums to host guests.
A bill in Ohio would prohibit state lawmakers from knowingly accepting free or discounted tickets to pro sports events. The proposal comes amid negotiations with the Cleveland Browns over public funding for a new stadium.
Offering free admission and luxury suites to lawmakers who make decisions about publicly funding stadiums creates a clear conflict of interest.
From a taxpayer perspective, such perks can divert public resources if lawmakers have an incentive to offer a team or other megaproject a tax break when that revenue could go toward broadly shared public benefits. From a free-market standpoint, these arrangements distort competition by subsidizing select teams and projects rather than encouraging municipalities to make themselves attractive for private investment.
Illinois legislators should ensure that any stadium agreement with the Bears does not include free tickets or luxury accommodations for lawmakers.
Perks for politicians are only half the story. The proposed incentive package in Springfield, HB 910 House Amendment 1, would be devastating for taxpayers.
Much of the current discussion revolves around the massive property tax reductions the bill would provide for so-called megaprojects as an attempt to spur economic development.
While negotiating targeted tax incentives is bad policy to begin with, the legislation would make Illinois’ property tax crisis even worse for other taxpayers. Although approved megaprojects would pay steeply discounted property taxes, a clause in the bill allows a taxing body to count the cash value of the megaproject in its total assessed value.
In other words, taxing bodies can still increase taxes as if the project were paying normal tax rates, generating increased revenue, but the project would not pay those higher taxes. Neighboring businesses, homeowners and renters would pay more to make up for the team’s discount.
Here is some of what’s in the bill, which has passed out of committee and could be called for a full House vote any time:
- To qualify, a project must have at least $500 million in eligible costs, which can include the property purchase and can be retroactive up to five years before the megaproject certificate is issued. The project must be completed within seven to 10 years, but that can be extended by five years. The site must be operated for at least 20 years; the tax incentive would last at least 23 years and up to 40 years.
- The megaproject’s assessment would be frozen so that its property tax bill is calculated on the “base year” of the project, meaning the value of the property before any improvements, such as a stadium.
- However, for purposes of issuing bonds and property tax extension limitation calculations, the taxing body could use the current fair cash value of the property. In other words, new development, which is generally exempt from Property Tax Extension Limitation Laws, would allow for the levy to grow beyond the limited rate, which other taxpayers will have to cover.
The bill’s “incentive agreement” allows for separate payments from the megaproject entity, such as the Bears, or an alternative source, to affected taxing bodies in addition to property taxes bill. The payment amount would be negotiated with taxing bodies.
Illinoisans already pay the highest property taxes in the nation. Homeowners in Arlington Heights pay average annual property taxes of more than $8,000. HB910 would make it even worse. One simple solution is to strike this language from the bill:
“Projects to be valued at fair cash value for purposes of bonded indebtedness and limitations on property tax extensions. Projects to which an assessment freeze applies pursuant to this Division shall be valued at their fair cash value for purposes of calculating a municipality’s general obligation bond limits and a taxing district’s limitation on tax extensions.”
Removing that language would ensure that businesses, homeowners and renters in the megaproject area would not face higher property taxes because of an incentive agreement.

“Renewable energy alone won’t make our energy systems more just. The production, distribution, and consumption of energy are connected to many ethical issues. For example, even renewable energy projects can pollute environments or displace people. My recent research examines these ethical challenges and asks what a just transition might look like. I’ve also published work on climate ethics, trophy hunting lions, urban park design, interdisciplinary research, and dinosaur films. My most popular course is PHI 236: Values and the Environment, but I also teach many topics in moral, social-political, and environmental philosophy. I’m also a proud affiliate of the Women’s, Gender, and Sexuality Studies Program (WGSS).”
What are your proudest accomplishments during your time at Illinois State?
“I was awarded an American Council of Learned Societies’ fellowship for my work on energy democracy this year. I was nominated by our university for a Carnegie Fellowship in 2024. I was also very honored to receive a College of Arts and Sciences (CAS) Excellence Award for Outstanding Teaching in 2021. But I’m always the proudest when I hear about the success of my former students. I love getting emails about their new careers or their graduate studies in all kinds of fields: law, environmental work, and, of course, philosophy.”
What’s your favorite thing about Illinois State or the College of Arts and Sciences?
“I do my best research in conversation with students and colleagues in different fields. Our students and faculty are so talented. They’re often working on amazing projects. I learn so much from them. They encourage me to explore new research questions I wouldn’t have thought of on my own. Environmental problems are inherently interdisciplinary. I’m very grateful that CAS supports interdisciplinary work and programs, such as WGSS, Environmental Systems Science and Sustainability, and Civic Engagement. Philosophy lends itself so well to interdisciplinary relationships since there are philosophical questions at the heart of every field.”
Department of Philosophy Chair Christopher Horvath on Godoy:
“Dr. Eric Godoy is an innovative, student‑centered educator whose inclusive and interdisciplinary pedagogy consistently elevates the department’s instructional standards. He is deeply committed to creating learning environments that empower students from diverse backgrounds to engage meaningfully with complex philosophical issues. His leadership in curriculum development has made him one of the department’s most forward‑thinking educators. Complementing his teaching excellence, his research provides practical, ethically grounded solutions to energy‑policy conflicts and will shape national conversations about democratic participation in a just transition away from fossil fuels.”
