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.
Flood warnings for Eastern Iowa were released in late February. The Dewitt area is especially susceptible, as the local river, the Wapsipinicon, is expected to rise .3 feet higher than its typical flood level. Though the area is used to flooding, the warnings are still something to heed.
Floods are often caused by a combination of heavy spring rains and melting snow, causing rivers throughout the Midwest to overfill and spill onto their banks, often irreparably damaging property in the process. The Midwest is especially vulnerable to flooding because of the generally temperate climate–snowy winters and stormy springs bring high levels of river water.
While Iowa has not seen a truly disastrous flood since 2008, the Flood Center emphasizes the importance of predictions and preparation. Recent projects around Iowa, such as the raising of Dubuque Street in Iowa City or the flood control system in Cedar Rapids, are just a few of the precautions being taken to guard against future floods. The 2008 flood damaged crops and forced citizens to evacuate their homes, affecting everything from business to college facilities.
The Iowa Flood Center hopes that, by educating people about the dangers of flooding, future flood damaged can be reduced overall.
This week’s segment summaries the report from the 2017 Iowa DNR’s Water Summary.
The Iowa DNR’s Water Summary Update reported less rainfall than normal for 2017.
This is the Iowa Environmental Focus.
In 2017, Iowa received 33 inches of rainfall which is 2 inches less than the 30 year average. The beginning of the year was drought free but by August the Drought Mitigation Center recorded most of the state showing some form of drought. Most of the dryness was concentrated in South and South East Iowa.
In areas like Marion, Washington, Lee and Wayne counties, annual precipitation deficits of 10 inches or more were common. The annual precipitation levels of 2017 were the lowest since Iowa’s record 2012 drought.
In terms of streamflow, the year started off with high levels after a rainy fall season in 2016. Throughout the rest of the year streamflow levels remained normal and are currently normal for the majority of the state.
Since Trump has officially pulled support from the Paris Climate Change Accord, mayors within the U.S. are pledging for their cities to help meet the goals. 50 plus mayors signed the Chicago Climate Charter to meet Paris Climate Agreement’s pollution reduction goals during the North American Climate Summit. Des Moines, Dubuque, Fairfield, Iowa City, Cedar Rapids and several other Iowan mayors have now stepped up to do the same.
