Since 2011, researchers and educators at nearly every college and university in Iowa have produced annual statements to communicate in plain language the state of climate science and the impacts of climate change on Iowans.
The video above shows the 2021 Climate Statement read aloud by those who worked on it. They warn about extreme temperatures, floods, droughts and extreme storms.
The presenters also share what can be done to help prevent some climate disasters. This includes changing infrastructure to accommodate for extreme weather patterns.
In 1991, scientists accurately predicted climate change would lead to a warmer and wetter Midwest in the spring and summer. Now, 5-day heat wave temperatures in Iowa are anticipated to increase around 7° F in an average year and 13° F once per decade, in comparison to the late 20th century.
The impact of these findings go beyond weather patterns, degraded public infrastructure is one major ways everyday life will be altered by the new climate. In 2018, a group of climate scientists and researchers from across the state focused the Iowa Climate Statement on infrastructure to emphasize their concerns. In the statement, they explain how daily total rainfall is expected to double in intensity by 2025.
Flooding along Iowa’s eastern and western borders in 2019 alone resulted in $1.6 billion in damages, according to the Des Moines Register. “…This type of flooding in this region is expected to become even more likely in the future if we do not take immediate actions to cut greenhouse gas emissions,” said University of Iowa Researcher Wei Zhang.
Scientists recommend buildings be designed to withstand heavier rain by integrating rain screens, large gutters and downspouts. For the hot summer greater insulation, improved ventilation, planting of shade trees and more are needed.
Since 2011, the Center for Global and Regional Environmental Research has co-produced an annual Iowa Climate Statement to explain the impact of climate change on Iowa. Released in early October early, nearly every Iowa college and university has agreed to the statement.
The UI Center for Global and Regional Environmental Research is excited to announce the revival and reimagination of our EnvIowa podcast. This weekly podcast will feature 10- to 20-minute interviews with Iowa environmental experts, mainly our own member scientists.
While these researchers are certainly well versed in the complicated jargon of their disciplines, our interviews aim to make their ideas accessible to a general audience. Questions focus not only on the research itself, but how the experts believe it can be applied to solve environmental challenges.
Today’s installment features an interview recorded January 28 with Dr. Silvia Secchi, an interdisciplinary economist and geographer at the University of Iowa. Listen to learn more about Dr. Secchi’s fascinating research on human/environmental interactions in the Mississippi River watershed and how agriculture in particular plays a role within the larger system.
The Iowa Climate Statement video has officially been uploaded to our website. You can watch the video again here, or access it at any time under the Iowa Climate Statement tab.
The statement, released on September 18, warns Iowans and Midwesterners of sobering extreme heat projections for the region. Based on the most up‐to‐date scientific sources, the statement makes clear the urgency of preparing for dangerously hot summers in the coming decades.

The Iowa Climate Statement 2019: Dangerous Heat Events to Become More Frequent and Severe was released yesterday at press conferences in Des Moines and Cedar Rapids.
Yesterday, at the Cedar Rapids Press Conference, Dr. Jerry Schnoor was asked what he would say to individuals that do not currently see climate change as a major issue.
This year’s statement warns Iowans and Midwesterners of sobering extreme heat projections for the region. Based on the most up-to-date scientific sources, the statement makes clear the urgency of preparing for dangerously hot summers in coming decades. The statement describes some of the sobering impacts of hotter heat waves and more hot days. The 9th annual Iowa Climate Statement was endorsed by a record 216 science faculty, researchers and educators from 38 Iowa colleges and universities.

Just weeks after July 2019 became the hottest month on record, 212 faculty and researchers from 38 Iowa colleges and universities endorsed the 2019 Iowa Climate Statement: Dangerous Heat Events to Become More Frequent and Severe.
The UI Center for Global and Regional Environmental Research has released annual climate statements since 2011. These statements, vetted by hundreds of Iowa’s top experts, place pivotal climate change research into an Iowa-specific context, encouraging preparedness and resilience in the face of the climate crisis.
In their relatively short residence on Earth, humans have survived several dramatic climate change events, albeit with more natural causes than at present. They have endured man-made environmental challenges, like deforestation, as well.
So could the key to modern climate adaptation lie in the triumphs and mistakes of ancient civilizations? Matthew Hill, associate professor of anthropology at the University of Iowa, sees potential.
“I think that you can use the past—carefully—to see patterns, see how certain strategies were attempted to deal with these environmental changes and see whether they have failed or succeeded,” Hill said. “I see it as one helpful guidepost to how people have responded to similar changes.”
Anthropology, broadly, is the study of human cultures. Hill primarily focuses on human interactions with the environment. As an archaeologist, he spends a lot of time studying ancient peoples and their technologies—specifically, how indigenous hunters interacted with animal populations in North America.
Hill describes his research on ancient North American peoples and animals.
One of his earliest studies involved North American bison. They sustained native populations in the Great Plains for tens of thousands of years but declined rapidly once Europeans joined the hunt. Hill sought to understand the differences in strategy and mindset that led to dramatically different outcomes for bison before and after colonization.
About half of Hill’s recent research focuses on modern humans, too. With an interdisciplinary team of Iowa researchers, he is studying the social and environmental positions of wood-burning stove users in rural India.
“We’re trying to understand how these women are coping and adapting to a changing environment, one in which there’s deforestation and one in which governments and international organizations are targeting their way of life for change,” he said.
Hill discusses his research on biomass burning in rural India.
Adaptation is the common thread throughout Hill’s projects. In both past and present peoples, he has examined a number of successful and failed strategies for dealing with all sorts of environmental problems.
As he sees it, innovation is not an issue. He said people have always been clever and able to develop new technologies and approaches. The bigger problem seems to be motivating political and economic elites to work towards positive change.
“Even if there’s goodwill, there’s not a single direction that a country or large group moves toward,” Hill said. “It’s often contradictory forces.”
Hear Hill’s thoughts on the political reality of environmental action.
The masses often have more incentive –they are harmed by environmental isues far more than elites – but the poor and disenfranchised typically lack adequate resources to be a “positive push forward,” he said. It is up to leaders to be proactive and implement solutions that work for everyone.
But still, successful adaptation is possible. Hill pointed to North American big game hunters as evidence. At the end of the paleolithic Ice Age they faced mass extinction of food sources like mammoths and mastodons.
Amazingly, they managed to “not just survive but thrive,” he said. He attributes thoughtful resource management and long-term planning to their success.
“We can only hope that American society can point to these kinds of behaviors,” Hill said. “Not just thinking about next quarter or the next year, but thinking about the next generations, we too can not just survive change, but flourish in the face of change.”

The Iowa Climate Statement 2018: Designing Buildings and Communities for Iowa’s Future Climate was released earlier today at the Cedar Rapids Public Library. The statement was announced by Jerry Schnoor, the co-director of the University of Iowa’s Center for Global and Regional Environmental Research, and Ulrike Passe, Associate Professor of Architecture at Iowa State University.
The eighth annual statement, “Iowa Climate Statement 2018: Designing Buildings and Communities for Iowa’s Future Climate,” released Thursday, October 11 was signed by a record 201 science faculty and researchers from 37 Iowa colleges and universities. The statement describes the urgent need to fortify our building and public infrastructure from heat and precipitation and looks to the future weather of Iowa, suggesting ways to improve Iowa’s buildings to suit those changing weather patterns.
In years past by September, Iowa no longer expects rain. However that is obviously not the case with heavy rainfall the past 10 days and more expected in the forecast. Professor Gabriele Villarini, a faculty affiliate of the Iowa Flood Center at the University of Iowa, paired with Assistant Research Scientist Wei Zhang to develop the images above for context around the rain we are currently experiencing.
The top left panel shows that from 1981 to 2010 Iowa could expect at most 2 inches of rain in August and September. The bottom left panel shows that we are currently expecting 8-10 inches.
The top right panel shows that in this time period, Iowa is experiencing the most rainfall since 1948. The bottom right panel shows that in some areas there is more than 80% rain now than the second largest rainfall.
University of Iowa professor Andrew Forbes has been conducting research that may intimidate those who aren’t fans of parasitic wasps. Forbes specializes in studying these wasps that belong to the Hymenoptera order, which also includes insects such as bees and ants.
In a preprint paper, meaning it has not yet been peer reviewed, Forbes asserts that the Hymenoptera order is more species rich than originally thought. Previously, Coleoptera— the beetle order, was thought to be the most speciose. However, Forbes’ specialization in parasitoid wasps allowed him to make the connection that there can be multiple species of parasitic wasps preying upon a single species of insect. Based on this ratio, one species of host insect to many different species of parasitic wasps, it would make sense that Hymenoptera is the most species rich order. The paper concludes that Hymenoptera has perhaps 2.5-3.2 times more species rich than Coleoptera.
