The University of Iowa was very lucky to receive a visit from scientist, researcher, and adjunct professor Dr. James Hansen. He was gracious enough to sit down with us and interview about his work, education, and relationship with Dr. James Van Allen.
Hansen was trained in astronomy and physics under Dr. Van Allen at the University of Iowa, graduating with the highest distinction in 1963; he then published his dissertation on Venus and helped launch the Pioneer Venus project in May of 1978. Hansen was the head of the NASA Goddard Institute for Space Studies in New York from 1981 to 2013. Today, he continues his work on climate change as the director of the Program on Climate Science at Columbia University’s Earth Institute, and gave a TED talk on climate change in 2012.
This video, discussing his work, will be the first of a 3 part video series. Tomorrow, Dr. Hansen will speak directly to students and the following day will focus on his relationship with Dr. Van Allen.
The Getting Ahead of the Watershed Expo will be held in the Davenport River Center’s Mississippi Hall on Saturday, March 10th from 10am to 3pm.
This is a free event, presented by students of Davenport North High School and Davenport Public Works, that aims to raise awareness about the quality of our waterways and individual impact on water quality through engaging demonstrations and exhibits.
The event will feature several interactive student and vendor booths with topics ranging from environmentally positive ways to increase the curb appeal of your home to locks and dams and levees. In addition to interactive displays, a play featuring Franny the Fish, is sure to bring a smile to all ages, while delivering important information about our watershed.
There will also be a 9ft+ root system of native grass Big Blue Stem. The root system is certain to amaze and highlight the ecosystem, soil and water quality benefits of native plants in our landscape.
Attendees will also enjoy theDavenport Community School student artwork on display at the Expo, and to vote for their favorite art piece and booth, as well as enter a drawing for a beautifully decorated rain barrel.
To test their theory, PhD student, Hadayet Ullah and supervisors Professor Ivan Nagelkerken and Associate Professor Damien Fordham of the University’s Environment Institute, managed twelve 1,600 liter tanks that mimicked the predicted habitat changes in the ocean. The recreated food webs were maintained for 6 months while the researchers gathered information on survival, growth, biomass, and productivity of the animals and plants to use these measurements in a food web model.
A food web maps out the flow of energy in an ecosystem. At the bottom are algae and other food producers, then intermediate consumers like herbivores and finally predators at the tops. Shifts in the bottom of the energy transfer affects the amount of food available for predators.
“Healthy food webs are important for maintenance of species diversity and provide a source of income and food for millions of people worldwide,” said Mr Ullah. “Therefore, it is important to understand how climate change is altering marine food webs in the near future.”
At the end of the 6 months they found, “climate change increased the productivity of plants, this was mainly due to an expansion of cyanobacteria (small blue-green algae),” said Mr Ullah. “This increased primary productivity does not support food webs, however, because these cyanobacteria are largely unpalatable and they are not consumed by herbivores.” Less food for herbivores would result in a smaller population which means less food for predators.
Hydrothermal liquefaction is a process where the food is heated (kind of like a pressure cooker) to extract oil that can be used for fuel.
The anaerobic digestion process breaks down the microbes in the food waste into a mixture primarily composed of methane and carbon dioxide. This gas can be used to power heat and electricity.
Other methods of turning food waste into energy are also being developed but Roy Posmanik, a postdoctoral researcher at Cornell, is really excited about this quick new solution. “We’re talking about minutes in hydrothermal liquefaction and a few days in an anaerobic digester,” he said in a written statement. Posmanik says he could see a day where all food waste from homes, supermarkets, restaurants are immediately shipped to treatment plans. Posmanik needs to do more research before he discovers the cost but “government incentives for renewable energy credits can make a lot of difference.”
In this episode of EnvIowa, we talk with Jeff Biggers, writer in residence at the University of Iowa and Natalie Himmel, an English and International Studies Major at the University of Iowa about the Climate Narrative Project.
The Climate Narrative Project, launched in 2014, is a special media arts initiative through the UI Office of Sustainability designed to train a new generation of climate storytellers. The project reaches across many academic disciplines using theatre, film, creative writing, spoken word poetry, yoga, and dance to grapple with how stories can change the way we view climate and spur action.
Over the past three years, Climate Narrative fellows have produced a wide variety of art projects including short films, theatrical monologs, and creative writing pieces. The projects center around localized themes related to climate change. Past themes have included the role of water and the Iowa River, soil carbon sequestration and prairie restoration, local food and regenerative agriculture, and climate migration.
This semester the project will focus on exploring ways in which we can live in regenerative cities in an age of climate change.
Since its inception, the Climate Narrative Project has brought in a wide range of undergraduates and grad students from many Colleges and departments including the College of Liberal Arts and Sciences, College of Education, College of Engineering, College of Public Health, Tippie College of Business and Graduate College.
The Climate Narrative Project serves as a partner for the Yale Climate Connections nationally syndicated public radio program. In 2014, Yale featured the Climate Narrative Project: Climate As Local Narrative.
Join the Climate Narrative Project Fellows tonight for an evening of film, theatre, art and storytelling focused on issues of climate justice and climate change.
Wednesdsay, December 7 7:30 p.m. – 9 p.m. Becker Communication Studies Building Rm 101
The Climate Narrative Project is a special media arts initiative through the Office of Sustainability designed to reach across multilpe academic disciplines and provide regenerative approaches to energy, food, agriculture, water and waste management, community planning, and transportation.
Jeff Biggers is the Writer-in-Residence at the University of Iowa’s Office of Sustainability, where he oversees the Climate Narrative Project.
This semester, eight fellows worked with Biggers on semester-long investigative projects. This year’s eight fellows include:
Shelby Cain:The Conscience and the Consumer Carlo Acevedo: El clima y la justicia:Poemas Shirley Wan: Voices of Huo Nazira Coury: The Other Side: Las Voces J. Creek Hoard: Four Walks Solomon Worlds:Edu-nature-nal Kate Gylten: The Art of Oil Jeffery Recker: Not One or a Million
The Climate Narrative Project is an investigative initiative: What accounts for the gap between science and action on climate change, and what can we do more effectively to communicate informed stories and galvanize action?
The intern program matches up Iowa businesses interested in ways to reduce and eliminate waste from their operations that improve environmental performance and save money with engineering students. Since 2001, companies involved have saved more than $81.9 million from projects through the intern program.
Within the program, interns recommend and implement projects that will help Iowa businesses improve the ways in which they use resources. These projects divert waste from landfills, reduce hazardous waste, conserve energy and water, and reduce greenhouse gas emissions. The annual environmental reductions generated in 2016 include:
1.16 billion gallons of water
1,215 tons of solid and special waste
1,215 tons of hazardous waste
1.2 million kilowatt hours
4,220 MTCO2e (metric tons of carbon dioxide equivalent)
“The real value of the intern program has been to obtain a talented engineering student to compile data and provide in-depth technical analysis, with actionable recommendations,” said Todd Fails, Site Services Team Leader at Zoetis Global Supply in Charles City. “The results from our projects have helped us to make informed decisions that improve our efficiency and reduce our operating costs.”
The engineering students from Iowa’s state universities, after a week of training and orientation with program advisors, work at selected businesses to analyze their current systems, research alternative processes and technologies, and recommend cost-effective strategies that will improve the way they produce, consume, reuse, and recycle their resources.
