This week’s On The Radio segment takes a closer look at Cedar Rapid’s first-ever sustainability coordinator and University of Iowa graduate, Eric Holthaus. 

Transcript: New Cedar Rapids sustainability coordinator provides multifaceted momentum

Cedar Rapids has hired its first-ever sustainability coordinator.

This is the Iowa Environmental Focus.

Eric Holthaus, a University of Iowa graduate, was hired on to provide focus and strategy to existing city-wide sustainability initiatives and to spearhead new efforts. Since beginning his work with the city in November, he helped implement a 90 kilowatt solar panel array on the roof of the Northwest Cedar Rapids Transit Garage and establish a policy that prohibits city vehicles from idling for longer than one minute.

Upon his hire, Holthaus created a 21-point sustainability assessment of the city. In addition to other findings, he notes that Cedar Rapids has clean drinking water, but difficulty with “food deserts,” or areas of town where populations have restricted access to food.

At the end of June, Holthaus and his team released a document titled, “State of Affairs: Cedar Rapids’ Pursuit of Sustainability.” The document lays a foundational definition for sustainability and why it matters to people in Cedar Rapids.

To Holthaus, sustainability reaches beyond environmental issues,

HOLTHAUS: “And so sustainability to me is be able to have a high quality of life, and it also means to me to connect the social and economic aspects. A lot of people don’t meet their daily needs, you know, if there’s an opportunity for us to eat better, to have cleaner water, to have more access to those resources, how can prioritize people that have the least and build stronger communities when we do that intentionally?”

Cedar Rapids is only the third city in the Hawkeye state to create a sustainability coordinator position, following Iowa City and Dubuque.

The Bakken oil pipeline received a final go-ahead from the U.S. Army Corps of Engineers on Tuesday for construction in Iowa. Dakota Access, a subsidiary of Texas company, Energy Transfer Partners, had already received full permission from all other states along the pipeline’s path including Illinois, North Dakota, and South Dakota. The company received notice yesterday from Corps of Engineers in Rock Island, Illinois that all construction in Iowa complies with federal environmental laws and is authorized.

The Army Corps of Engineers verification letter permits the construction of parts of the pipeline that cross bodies of water, including major rivers. While the Iowa Utilities Board previously granted development in parts of the state, this is the final regulatory hurdle for the Bakken pipeline. Iowa Citizens for Community Improvement, a community organization that opposes the pipeline, is concerned about its crossing of 64 Iowa waterways.

Dick Lamb, a landowner in Boone county along the pipeline’s route, echoes their concern, “It isn’t a question of if, but when it will leak, and when it does it will irreparably destroy valuable Iowa farmland and the waterways we depend on.” An going lawsuit filed by 10 affected landowners challenges Dakota Access’ use of eminent domain to gain access to private Iowa land.

Many labor unions in Iowa look forward to the development of the Bakken pipeline. President of the Iowa State Building and Construction Trades Council, Bill Gehard, said, “Thousands of American workers from labor unions throughout the Midwest are already benefiting from this project, and these final permits will secure their jobs for the entirety of construction.”

The water crossing permits mandate follow-up inspections for compliance to regulation and monitored wetland mitigation. The finished pipeline will run from the Bakken oil fields in North Dakota to Patoka, Illinois, crossing 18 Iowa counties along the way. It will move 570,000 barrels of oil daily into Midwest, East coast, and Gulf Coast markets.

An Iowa City business owner has begun growing hydroponic vegetables on his downtown rooftop.

Mark Ginsberg, owner of a jewelry design studio and store called M.C. Ginsberg, has around 35 square-feet of hydroponic plants growing atop his business. Hydroponic gardens are systems in which plants can grow without soil, receiving the bulk of their nutrients from natural fertilizers in water like worm or fish waste. This nutrient rich water flows under plants and through root systems to sustain plant growth. Chad Treloar, Ginsberg’s construction lead for the project, built the garden with inexpensive, easy to acquire materials like PVC pipe, wood, and food-grade tubs.

In an interview with the Gazette, Ginsberg said that it would be possible to turn all urban Iowa City rooftops into food growing operations like his. He will harvest cucumbers, peas, and tomatoes first; he plans to give his bounty away to local restaurants and bars. In the coming years, MC Ginsberg’s garden will aim to sell its produce, depending on vegetable quality and yield dependability. Local restaurants seem eager to support the project, Oasis Falafel has already asked for all of the MC Ginsberg cilantro harvest.

In the long-term, Ginsberg is working to make hydroponic garden designs available to other downtown business owners. He aims to create a system that would allow owners to input rooftop dimensions and receive a cheap plan for hydroponic garden construction in return. He expects he could make these plans available for as little as 99 cents.

Green-roofs like these offer advantages to growers like runoff delay and stormwater management, improved air quality, and healthy foods with a small carbon footprint.

Iowa City Downtown District Executive Director Nancy Bird said the district is looking to back more projects like Ginsberg’s as a part of their larger sustainability focus for the downtown area.

Iowa City Science Boosters Club at the Linn County Fair

The Iowa City Science Boosters Club taught children about climate change through a hands-on experiment at the Linn County Fair on Thursday June 23.

Hundreds of children stopped by the ICSBC booth in the Lynn Dunn Memorial Building at the Linn County Fairgrounds to learn about the effects that ocean acidification can have on marine life. Participants blew bubbles into cups of water and then measured the water’s pH level. They found the carbon from their breath lowered the pH level similar to how with climate change excess carbon in the atmosphere contributes to more acidity in oceans. The higher acidity level in oceans can damage the shells of mussels, clams, and other shellfish which can make them more susceptible to predators and create a whole slew of ecological issues.

“We’re here for youth day and this is related to our outreach work with schools. The National Center for Science Education is really interested in changing community attitudes towards science education and supporting science teachers,” said Emily Schoerning, Director of Research at the National Center for Science Education. “So if we can give these families a positive, upbeat, hands-on experience with climate change that will make them less concerned with talking about climate change and less concerned about their kids learning about climate change in schools.”

Schoerning also said that the ICSBC has raised more than $10,000 in its first year which provided Iowa classrooms with durable science equipment.

This week’s On The Radio segment looks at a recent study that examines how climate change affects extreme weather events such as floods and droughts.


Transcript: Attributing extreme weather to climate change

Scientists are becoming increasingly confident attributing extreme weather events to human-caused climate change.

This is the Iowa Environmental Focus.

A March study led by The National Academy of Sciences concludes that scientists are more able to determine how climate change affects the intensity and likelihood of some extreme weather events like floods and droughts. Extreme event attribution, a relatively new science according to the study, has made rapid advancements in the last ten years.

After extreme weather events like the record-breaking precipitation Iowans experienced in the winter of 2015, scientists are often asked if these events can be attributed to climate change. While few if any phenomena can be explained by climate change alone, scientists are now better able to determine how much of an effect climate change may have.

Educators in Iowa differ in their opinions of how to teach climate change, according to a pair of surveys conducted in a collaboration by Iowa Watch and the Cedar Falls High School newspaper Tiger Hi-Line.

The two separate surveys show the views of both teachers and students for how to approach climate change education. While the survey results from the sample of 133 Iowa teachers were not large enough to show a clear trend, the findings were consistent with a study by the National Center for Science Education published in the journal Science earlier this year. Nearly half (48 percent) of the teachers polled in the Iowa survey said that climate change should be taught as theory and that multiple theories exist without consensus on which ones are right or wrong.

The student survey polled 245 pupils from six Iowa high schools and one middle school. While students and teachers were generally in agreement for their personal opinions on climate change (81 percent of teachers and 60 percent of students responded that “Global temperatures are getting warmer and having an impact on weather patterns”) and humans’ role in climate change (62 of teachers and 42 percent of students responded that “Human activity contributes to climate change as well as natural changes in the environment”), the two groups differed in where they get their information about climate change. A majority of students (60 percent) cited news reports as the main source they use for forming their views on climate change compared to the majority of teachers (95 percent) who cited scientific reports as their main source of climate information.

Since 2013, the annual Iowa Climate Science Educators Forum has served as a workshop for science educators to learn about the latest scientific research in regard to climate change as well as effective methods for teaching climate-related courses to students.

This week’s On The Radio segment looks at a Des Moines sorority that is part of an initiative to teach high school students about the ways that climate change affects different countries.  

Transcript: Des Moines sorority engages students on climate change

An Iowa sorority is working on a new effort to teach Des Moines-area students about climate change.

This is the Iowa Environmental Focus.

Des Moines was selected as one of ten cities nationwide to be part of an EPA-funded project to bring a climate change curriculum to high needs students. Members of the Iota Zeta Omega chapter of the Alpha Kappa Alpha Sorority have worked with students at North High School in Des Moines and aim to engage 1,000 students city-wide. Participants in the program role-play as ambassadors from various nations to understand how climate change affects countries differently.

The Chapter’s Vice President and Program Chair Lagi Roberts said the program serves as an important learning opportunity for students involved.

Roberts: “I believe exposing students from communities disconnected from international concerns like climate change, is not only important, but necessary. This experimental learning opportunity enables students from high needs communities to engage in international climate change concerns and dialogs that they may have never been exposed to. Students are introduced to life changing skills like, decisive decision making, critical thinking, public speaking and cross cultural understanding, all skills in which these young leaders need in order to succeed.  The climate change mini-simulation classroom curriculum is allowing these students the opportunity to do just that by successfully shaping college and career ready young people.”

Alpha Kappa Alpha is the nation’s first and oldest sorority for African American college trained women. The Des Moines Graduate chapter consists of women who have graduated from colleges and universities nation-wide including alumnae of the University of Iowa, Iowa State University and Drake University.
