The Iowa City Climate Fest begins today and will celebrate the different ways that our community is coming together to address climate change throughout the week.
There will be no in-person activities this year due to the COVID-19 pandemic, but the organizers have planned daily personal challenges and virtual community events to keep the celebration going. Details can be accessed through their website. Today’s activities center around celebrating better transportation options, and there will be a knew theme each day.
Local businesses, organizations, and individuals can also get involved by printing off coloring sheets to decorate and hang in windows or submit videos, pictures or posts telling their personal climate action story. Anyone who is interested in taking alternative actions for reducing emissions in Iowa City is also encouraged to check out their Climate Action Toolkit.
April 22, 2020, is not just another Earth Day. It is the 50th anniversary of the first Earth Day – the one that changed my life forever. Naive and over my head as student body president at Iowa State-1970, my world was on fire with righteous indignation against a compulsory draft for an unjust War in Vietnam. At times I actually thought that it would tear the country apart.
The first Earth Day strangely diverted my immediate attention, and the diversion would last a lifetime. Brainchild of Senator Gaylord Nelson and organized by Denis Hayes as a national Teach-In, Earth Da
y spawned immense bipartisan gatherings of 20 million people in the streets for one unifying goal – a healthy Planet Earth. Earth Day ignited in me a realization that my chemical engineering education from ISU could morph into something green and more fascinating, that is, trying to understand water quality, biodiversity, and the biogeochemistry of Earth’s processes. Discerning remedies for the massive disruptions that 7.7 billion people and an $80 trillion GWP can inflict on the earth has proven even more challenging.
This year we celebrate Earth Day with digital gatherings due to coronavirus. It’s not the same, but perhaps the pandemic can teach us some valuable lessons. Some people were slow to accept the dismal science of a spreading pandemic – they lacked trust in health professionals’ recommendations for social distancing, staying home, and closing businesses, sporting events, churches and social gatherings. But the flattening curves of Wuhan, South Korea, Singapore, and even Italy, Spain, and New York bear testament to the wisdom of their call.
Our national plan for the pandemic Covid-19 was non-existent, like the Emperor’s new clothes, plain for all to see. Pandemics are “global disease outbreaks” and they require national plans and concerted global action. As recently as 2003-2004, WHO mitigated much more rapidly a similar virus, SARS, by careful messaging and international cooperation of 11 labs in 9 different countries. U.S. and Chinese scientists together developed a vaccine within a year. Far too little cooperation exists today, both at home and abroad. Politics and hyper partisanship are disastrous in a time of global need. We can do better.
Analogies between climate change and our pandemic response are obvious. We have no national plan for either. As a young egg-head professor at the University of Iowa, I published my first modeling paper on climate change and its consequences in 1994, many years after others had done so. It projected (surprisingly accurately) the concentration of carbon dioxide in the atmosphere today with business-as-usual. That’s exactly what happened – business as usual. If you had told me that the U.S. would still not have comprehensive climate change and energy legislation in 2020, I would have told you, “you’re crazy”.
But it’s in the history books. We have failed to listen to the science and failed to reduce our gargantuan greenhouse gas emissions — the planet cannot take it anymore. Now it really is a Climate Emergency. What’s more, we are threatening to extinct 1 million species in the next generation as well – the Biodiversity Crisis.
Coronavirus humbles us all. How can one not be moved by the sight of doctors, nurses, custodians, and admissions clerks risking their lives for the rest of us? How can one not weep to see the miles of cars lined-up at food banks because families have nowhere else to turn? Playing out in the richest country in the world gives great pause.
Yes, we need science-based decision making on coronavirus and on climate change, but we need compassion and understanding as well. Noted columnist Sarah Van Gelder writes, “Changing hearts and opening minds begins when we listen”. Imagine the world we want, where everyone is safe and healthy, where the air is clean and the water is pure. Then, let us celebrate the 50th Anniversary of that spontaneous, bipartisan, original Earth Day by speaking from the heart and listening to each other.
Jerry Schnoor is professor of civil and environmental engineering and co-director of the Center for Global and Regional Research at the University of Iowa.
Researchers from the University of Iowa spoke at a press conference last week about rising temperatures in the state. The models used in the 2019 Iowa Climate Statement indicate that the number of days over 90 degrees in Iowa will rise from 23 to 67 by 2050.
Jerry Schnoor, co-director of the University of Iowa’s Center for Global and Regional Environmental Research, spoke at the Cedar Rapids Public Library on Wednesday, September 18th about the changes needed to decrease greenhouse gas emissions.
Those changes include solar farms and installing solar panels on homes, building wind turbines, improving energy efficiency and battery storage, along with carbon sequestration, regenerative agriculture practices, and reforestation. “All of these things take time. It takes time to change our infrastructure,” Schnoor said, but added that action is necessary in the next 16 months.
Peter Thorne, of the UI Environmental Health Sciences Research Center, also spoke at the press conference, warning of the health risks posed by extreme heat. Heat is responsible for more than 600 deaths in the U.S. every year, making it the leading cause of weather-related deaths, according to the Center for Disease Control.
Schnoor and Thorne also suggested infrastructure improvements to help prevent these deaths. This could include a program to cool homes during hotter months the way the Low-income Home Energy Assistance Program helps with heating costs during the winter.
Sometimes Jerry Schnoor looks like a typical engineer, running models and making projections using computers and mathematics. Other times he looks more like a forester, working with soil and seeds to clean up chemical contamination through a process called phytoremediation.
The co-director of the UI Center for Global and Regional Environmental Research has spent over 40 years in civil and environmental engineering, studying some of humanity’s greatest challenges. His work primarily focuses on climate change and environmental contamination, with an emphasis on water quality.
“I guess it’s all a part of sustainability, written large,” Schnoor said. “We want there to be an adequate supply of water for people and biota and industry and agriculture forever. Ad infinitum. That’s what sustainability is about.”
Schnoor discusses his work with phytoremediation.
Iowa’s water is so bad, he said, he wouldn’t want to swim in our lakes or eat fish caught in our streams. Most of the pollution comes from the state’s predominant agricultural landscape.
Soil constantly washes off of farm fields and into waterways. It brings with it nitrogen and phosphorous, which occur naturally in the soil and are often boosted with fertilizers. High concentrations of these nutrients cause harmful algal blooms, which create issues on a local and global scale.
Such blooms can release toxins that make water unsuitable for drinking and recreation. They also trigger a chain of ecological reactions which eventually starve the water of oxygen, making it inhospitable for aquatic life. Runoff into the Mississippi River from farm states like Iowa has created one such “dead zone” in the Gulf of Mexico spanning over 6,000 square miles.
“We’re not there yet, but I have to think that we’re poised to make real improvements,” Schnoor said of these issues.
He looks forward to better soil management on farms—adoption of practices like cover crops and reduced tillage to minimize erosion—but climate change will likely put more pressure on such solutions.
Schnoor discusses his work involving climate change.
Experts project that Iowa will see an increase in severe storms in coming decades. More storm water will create more issues with flooding, as well as more soil erosion and nutrient-laden agricultural runoff.
Schnoor’s students run computer models that forecast water quality and crop conditions in climate change scenarios. If humanity fails to dramatically rein in carbon emissions in coming years, these impacts could be drastic.
“I hope that’s not true,” he said. “I hope we’re going to have comprehensive energy and greenhouse gas legislation in the future in this county, and that all countries abide by the promises that they made in the Paris Climate Agreement.”
Schnoor discusses responsible citizenship in the age of climate change.
Schnoor stressed especially that scientists like him can’t save the world on their own. He’s an engineer, but not a technology optimist.
He believes real progress requires changed hearts and minds among the masses and their elected representatives. People must recognize the urgency of the situation at hand.
“Technology holds some promise, but we won’t solve these problems without a change in the way we think,” he said. “The unilateralist approach won’t work because, after all, we are one planet.”

We aim to introduce readers to some of our members working across a wide breadth of disciplines, to share what the planet’s future looks like from their perspective and the implications of environmental research in their fields. ***
Schnoor was featured in the July 5th edition of ES&T in a commentary authored by Joel Gerard Burken, a former student of Schnoor’s who now serves on the faculty in the Department of Civil, Architectural and Environmental Engineering at the Missouri University of Science and Technology.
Burken – who holds his bachelor’s, master’s and PhD from the University of Iowa – recounted studying under Schnoor in the 1990s. Burken discussed Schnoor’s sincerity and passion when working with students and colleagues as well as his genuine concern for public health and the environment as opposed to just conducting research, gathering data, and publishing papers.
“Sincerity and culture are corner posts to Jerry that are just as important as remarkable acumen and abilities. Though his sincere quality of person, Jerry sets a solid foundation that he stand upon in scientific work and in using this foundation as a position for strong speech on important topics,” Burken wrote. “…Impacts we can have go beyond data generation and being involved in policy issues, and speaking out for what we believe to be important. Jerry certainly spoke out on topics of importance.”
Schnoor’s areas of research include global air issues, groundwater pollutant transport, and remediation.
ES&T is a biweekly, peer-reviewed scientific journal that covers research in environmental science, technology, and policy. For Burken’s full article and for links to various editorials Schnoor has published in ES&T, click here.
This week’s On The Radio segment looks at a recent article by a University of Iowa professor about methods for removing the use of chlorine in the drinking water disinfection process.
Transcript: UIowa’s Schnoor looks at ways to remove chlorine in water treatment
As the water contamination crisis continues in Flint, Michigan, a University of Iowa researcher is looking for ways to prevent a similar crisis in Iowa.
This is the Iowa Environmental Focus.
In a February perspective in the journal Science, UI Professor of Civil & Environmental Engineering Jerry Schnoor and researchers in the U.S. and western Europe offered their insights into the best ways to reduce tap water contaminants from public infrastructure. Among their preliminary findings is that residual disinfectants like chlorine may not be necessary if standards are in place.
Schnoor: “Chlorine, chlorine-oxide, and chloramines are strong oxidants used to maintain a disinfectant residual in water distribution pipes for safe drinking water. Changing from one form of chlorine to another at the water treatment plant can cause leaching of lead from old pipes, sauder, or faucets. That’s what happened some years ago to Washington D.C. when children were exposed to lead in their drinking water. In Europe, certain countries like the Netherlands have shown that a chlorine residual is not necessary, provided enough steps are taken to ensure advanced treatment of the water, replacement of the pipes periodically, and a clean distribution system.”
CGRER co-director Schnoor found that municipalities can deliver drinking water without disinfectants like chlorine as long as the water sources are protected and the water systems are adequately maintained. Replacing pipes at appropriate times has also decreased the need for residual disinfectants.
As the COP 21 climate conference enters its second week, three representatives from the University of Iowa’s Center for Global and regional Environmental Research (CGRER) are on the ground in Paris to cover the event. CGRER co-director Jerry Schnoor and graduate assistants Nick Fetty and KC McGinnis got together Monday afternoon for a question and answer session with Des Moines mayor Frank Cownie.
*Some quotes have been edited for length and clarity*
SCHNOOR: Today at COP 21, there was a meeting of the BlueGreen Alliance. Michael Brune – executive director of the Sierra Club – said cities are able to make dramatic progress compared to those at the national level, what’s he talking about and is that true?
COWNIE: What he’s talking about is the ability of cities to make decisions immediately. We don’t need to have an act of congress or an appropriation that might come 12 to 16 months down the road. If there are things that need to be done we can do them today. The federal government, short of a national emergency, is very slow to respond and react. We’re working in preparedness and mitigation techniques. We recognize from past experiences some of the vulnerabilities we have even in Iowa to extreme weather events such as flooding and extreme downpours which result in water issues: flooding, water quality issues, erosion. It talks about the future of the state of Iowa. It talks about the future of the city of Des Moines. So we’re able to jump in there and start working with it and we can immediately start working with some of our local players. So as mayor of the city of Des Moines, I can enlist some of my local businesses, schools, other governmental agencies, counties. We can partner together also talking to people in their own residences, their own homes, on what they can do to make some progress lowering their utility bills but more importantly, at least in the discussion here about carbon, by lessening their utility bills they can save 30, 40, 50 percent on their bill, it’s 30, 40, 50 percent less carbon they’re putting through their furnace.
SCHNOOR: For the city of Des Moines, what specific things can you cite in the area of sustainability and lowering your carbon footprint?
COWNIE: Well first of all, we’re one of the cities that signed on the Compact of Mayors agreement. There’s 120 cities that responded to the plea by the president of the United States to get local government to respond. What does that mean? It means that we’ve signed up and we’ve committed. Additionally, we’re going to do an inventory of our greenhouse gas emissions. The city of Des Moines has already done that. And then what you do is make a plan to mitigate and target for reductions. In Des Moines we’ve added hybrids and electric vehicles in our fleets. We’ve redone, re-purposed, re-energized buildings with new furnaces, new heating plans, new cooling plans, new windows, new doors, new insulation. Some of which we’ve really taken to the extreme level. Our old library, as you know you and I did a meeting there, that building is over 100 years old. It’s on the national historic registry. Now the World Food Prize is there. It’s a LEED platinum building and a historic structure. We’re doing all kinds of things with the public sector doing what we can do. Leading by example. And also using our powers at the city level to encourage our businesses to do the right thing. So when Wellmark made their new building, we offered some tax increment dollars to get them to rethink how they were going to build their new building and they came to an agreement with us and built the world’s largest – at the time of their opening – single-owner, single-occupant LEED platinum building in the world. Those are the kinds of things we like to see because it speaks to not only energy but it speaks to the health of buildings. It speaks to the food they serve. How people get to and from work using public transportation. So many aspects of it touch on carbon use.
SCHNOOR: Is an action agenda for a city like Des Moines somewhat easier to implement than say for a whole country?
COWNIE: That’s right. At the local level, one of the inspiring things we can do is I know mayors from around the country, I know them around Iowa. We share good ideas. I try to call it legitimate larceny. If somebody has a really good idea on how we can make improvements and achieve further reductions, I’ll steal their good idea and I hope they’ll steal mine.
SCHNOOR: There’s some wariness here at COP 21 that we’re going to fall short. There’s an emissions gap between what’s needed to control the environment to less than two degree warming, we seem to be short. And they’re talking about a more ambitious agenda. Could some of that ambition come from the Compact of Mayors and people like yourself?
COWNIE: Yes. I think that some of the talk I’ve heard is that if they have the cities and the cities commit, and the cities actually do the work and meet their goals, that could account for about 25 percent of that gap that you’re talking about achieving that two degree goal. But I think that one of the things that we all worry about is that there’s so much carbon in the atmosphere that there’s sort of a pent up increase that’s going to happen over the next 50 to 100 years, that we can’t do anything about today so we’ve got to lower the emissions. Figure out how to capture carbon. How to do so many different things and aggressively raise our ambitions to achieve many higher levels. I think local government is one of the places it can really move forward and we can spread that 25 percent hopefully to 50. We know that 70 percent of the energy that’s used happens in cities and the expansion and GDP and future is mostly going to be in cities so let’s rethink how the city ought to operate and let’s hope Des Moines is on the right track so we can get to a net zero city at some point or another.
