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.
This weeks segment talks about why Iowa and other mid-latitude states are experiencing hotter summers.
Summers in mid-latitudes, including Iowa, are warming faster than other seasons, a recent study found.
This is the Iowa Environmental Focus.
Between forty and sixty degrees latitude in the Northern Hemisphere, an area from the southern Iowa border to mid Canada warmed more rapidly in the summer than in the winter over a thirty-eight-year-period,
The study published in the journal Scienceattributed this finding to the fact that a substantial amount of Earth’s land mass is concentrated in this zone, and land tends to heat up more quickly than the ocean. This can have serious implications on agriculture, because much of this land is used to grow crops in the summer, particularly in Iowa.
This study was conducted using a fingerprint method, meaning the researchers could distinguish natural climatic warming from increased temperatures due to human activity.
On July 19th of this year, Marshalltown, IA was hit with a devastating tornado. 89 homes were destroyed and 525 sustained major damage. The tornado struck a low income part of town making it very difficult for the small town to bounce back. Many people in the area had little to no insurance.
Lennox and JBS Swift & Co., the two largest employers have made sizable donations to help rebuild property. With disaster relief help, several employers have been able to continue to provide health insurance to their employees despite no longer having jobs for them. However, the process is slow and there are many people in the town still living in destroyed homes despite the tornado occurring months ago. Marshall County Family Long Term Recovery Committee is currently going door to door to evaluate which homes can still be lived in long term. Greg Smith, chairman of the Iowa Disaster Human Resource Council, stated, “It is not unusual for the poorest of the community to become poorer after a disaster.”
There is also large concern from business owners they may not have the insurance money to rebuild their company. It is a city requirement to use the original materials instead of replacing it with something cheaper, like wood. The collapse of these business will leave many people unemployed.
Even after the physical damage is cleared away Marshalltown will likely face a difficult couple years. Jim Zaleski, the city’s economic development director and tourism marketer, has helped with tornado relief in other towns. He believes,” the tornado was a catalyst, ” and will “force the community to take some hard looks at what was going to happen over the next decade.”
This weeks segment talks about how Iowa is the country leader in soil conservation mapping.
Iowa is now one of the country’s leaders in soil conservation mapping.
This is the Iowa Environmental Focus.
Iowa officials have recently completed a map of the conservation efforts in the state. This map identifies the six different methods of soil conservation used in Iowa—including terraces, ponds, grassed waterways, sediment control basins, and more. The map shows where practices are deployed and how they are funded.
The map also acts as a visual for determining how different areas of Iowa are being funded for their conservation efforts, and whether that funding is public or private.
Iowa is the first state to conduct such a thorough analysis of its conservation practices statewide. The project took three years and was a joint effort between Iowa State University and the Iowa Department of Natural Resources. Researchers used something called LiDAR—laser imaging software—and years of aerial photographs to compile the conservation map.
Iowa State University is currently performing additional research to build a newer map, one that also shows the reduction of sediment and phosphorous buildup in Iowa’s waterways.

Mayor Brad Hart held a press conference yesterday stating that preparations were in place. City workers are preparing for 18 feet to be safe. Hart stated, “I’m confident that no matter how high the river gets this week, that we’ll rise above it and protect the community as best we possibly can.”
Right now there is expected to be no damage. City Public Works Director Jen Winter’s biggest concern is “water coming back into our storm sewer system and backing up.” “Unless something fails, we anticipate that no, that there would not be damage,” she said. “In some cases, depending on the age of a building, some people do get water in their basements despite the fact that we have kind of plugged off the river from backing up.”
Flavonoid is a group of phytonutrients found in fruits and vegetables that has recently been used as a natural preservative in food. The naturally occurring chemical is responsible for defending the plant against pathogens, pests, or other environmental stressors. It is also the reason onions, tea, strawberries, kale, grapes and other foods have such vivid colors.
During testing in a room temperature environment, food with flavonoids were able to stay fresh for 2 days without refrigeration while current artificial preservatives succumb to bacteria after 6 hours.
This research could not be announced at a better time as just last month the American Academy of Pediatrics had 67,000 pediatricians in the U.S. step forward about their concerns of nitrates and nitrites being used to preserve meat products. Research has show that nitrates and nitrites can interfere with thyroid hormone production, the metabolic process and cause gastrointestinal and nervous system cancers. Flavonoids are packed with vitamins and do not cause harm to the digestive system.
A former adviser to the World Health Organization and consultant Medical Oncologist, Dr. Gabriel Oon Chong Jin said in an interview, “Flavonoids are important natural food supplements with vitamins, but also used as food additives, without causing harm to the human system. This is unlike currently available artificial preservatives used in most processed foods such as aspartame and nitrates, which may cause cancer among other adverse health effects.”
The research team is being led by Professor William Chen, the Director of NTU’s Food Science & Technology program. The recent findings were published in last month’s Food Chemistry journal.
This weeks segment looks at how Google was able to reuse more than 100% of the energy they consumed in 2017.
Google has become one of the biggest corporate buyers of renewable energy.
This is the Iowa Environmental Focus.
The massive company planned to get 100% of their energy from renewable sources in 2017. At the end of the year, they exceeded that goal.
Google currently holds contracts to buy 3 gigawatts of renewable energy from a wind farm specifically built to power the corporation’s offices and satellite locations globally. The purchase is the largest investment in renewable energy by a corporation to date, making Google a top customer of green energy.
For 2017, the company ended up investing in and generating more green energy than it consumed, a cycle that keeps a steady supply of energy on hand. Google’s Senior Vice President Urs Holzle explained that they were working on over 25 green energy projects around the globe.
Other large companies are following in Google’s footsteps by investing in renewable sources.
