Earth’s climate continued to warm during September 2017, setting some alarming records.
September 2017 was the planet’s fourth warmest September since record-keeping began in 1880. The three warmest Septembers were in 2015, 2016 and 2014. This year’s September was especially notable because no El Niño effect was present. El Niño events typically bring warmer weather because they cause the ocean to release warm air into the atmosphere.
Sweltering temperatures were experienced across the globe. The hottest temperature in the Southern Hemisphere was 109 degrees Fahrenheit on September 27th in Birdsville, Australia. In the northern hemisphere, temperatures soared to 123 degrees Fahrenheit on September 3rd in Mitribah, Kuwait.
Record high temperatures are not without consequences. September 2017 also had the second lowest Antarctic sea ice cover during that month on record. The Arctic sea fared slightly better, coming in at number seven for record low sea ice cover during September.
Homeowners in Linn County were encouraged to combine their buying power to significantly reduce the cost of installing solar panels this summer through the Solarize Cedar Rapids and Linn County initiative.
Organized by the City of Cedar Rapids, Linn County, The Nature Conservancy, Indian Creek Nature Center, Iowa 350 and the Midwest Renewable Energy Association (MREA), participants were offered a significant per Watt discount each time the volume of buyers surpassed program tiers. The base price for participants was $2.45/W. All participants received a $0.05/W discount each time the group buy reached one of four milestones: 50 kilowatts (kW), 150 kW, 250 kW, and 350 kW.
The program offered a total of 23 educational sessions, or Solar Power Hours, for interested parties to learn more about the evolving solar industry and this initiative.
Amy Drahos is a Senior Air Quality Scientist at Linn County Public Health. She said in a recent press release, “The community support for the Solarize program has been incredible. Nearly 500 people attended a Solar Power Hour or requested more information about the program, with 105 households deciding to install solar. This program was a success thanks to the enthusiastic response from Linn County citizens and the dedicated community partners who recognize the benefits of solar energy.”
In the end, 105 households signed up to install solar panel systems, and the initiative nearly double its highest goal of 350 kW, installing a total of 611 kW. The large group buy means that participants will receive a rebate of $200 per kilowatt installed, or an average of $1,164 per household.
Cedar Rapids Sustainability Coordinator, Eric Holthaus, commented on the city’s role in the program, “The City served as an educational partner in this program. Solar technology ten years ago is not the same as solar today. We enjoyed helping residents become informed on this energy option, and it looks like many were excited to take a step toward cleaner energy and lower utility bills.”
The Solarize Cedar Rapids and Linn County initiative also provides a substantial environmental payoff. It is estimated that program participants will generate a combined total of nearly 700,000 kWh of clean solar energy annually. MREA reports that 927,000 pounds of carbon dioxide and 14 million gallons of water will be offset by this initiative during the first year alone.
The MREA has implemented this program in several other parts of the Midwest including Milwaukee, Wisconsin and Urbana-Champaign and Bloomington-Normal, Illinois. However, “The Solarize Cedar Rapids and Linn County program contributed the highest kW contracted to date,” according to MREA Executive Director, Nick Hylla. He added, “There is obviously a tremendous amount of interest in solar energy in eastern Iowa.”
The program wrapped up on September 30th. All solar installations will be completed by December 31, 2017.
Approximately 150 people gathered at Drake University in Des Moines for the “Challenges to Providing Safe Drinking Water in the Midwest-A Symposium” on September 21 and 22. Sponsored by several University of Iowa centers including the Environmental Health Sciences Research Center (EHSRC), Center for Health Effects of Environmental Contamination (CHEEC), Center for Global and Regional Environmental Research (CGRER), and the UI Public Policy Center, the event featured thirteen speakers.
Four plenary discussions about topics such as the health impacts of nitrate in drinking water, how to communicate with the public about water quality, unregulated contaminants in drinking water and more.
Under current law, applicants seeking to construct livestock facilities must meet only 50 percent of the state’s master matrix of rules and regulations pertaining to the structures. The petition, filed by two environmental groups, Iowa Citizens for Community Improvement and Food & Water Watch, requested that applicants meet at least 86 percent of the matrix’s requirements.
The Iowa Department of Natural Resources sided with the Iowa Environmental Protection Commission and recommended against passing the petition, both groups said that the proposed changes would be too stringent. Proponents of the petition pointed out that just two percent of applicants are denied permission to construct livestock feeding operations in the state of Iowa.
The current animal feeding operation master matrix was developed fifteen years ago by state lawmakers.

A new report out of a non-partisan Iowa City-based research center, Iowa Policy Project, states that drainage districts have the power to improve water quality in the state.
About one-third of cropland in Iowa is tiled for drainage. Agricultural drains channel water, which often carries heavy nitrate loads, from fields into local water waterways. Iowa’s nitrate runoff is a primary contributor to the growing Dead Zone at the mouth of the Mississippi River.
Researchers Sarah Garvin, Michael Burkart and David Osterberg recommended using Iowa’s “quasi-governmental” drainage districts an agent of change. The report explains that the districts have the statutory authority to mitigate nitrate runoff by “requiring water quality monitoring and reporting, wetland conservation and restoration, and mandating the installation of bioreactor at discharge points to reduce nitrate loads.”
The report also points out that under statutory mandate, drainage should be “a public benefit and conducive to the public health, convenience and welfare.” Nitrate levels in water at or below the Environmental Protection Agency’s standard of 10 mg/L is considered safe for consumption. However, some new research suggests that nitrate levels below this can pose some health threats. In either case, the report reads,”Public health and welfare should be interpreted to mean keeping our waterways free of nitrate pollution.”
David Osterberg, lead energy and environment researcher at Iowa Policy Project, said, “It’s going to require managers of drainage districts to step up at a time when their county supervisors cannot, even if they wanted to, and at a time the state legislature has stood in the way of local authority on industrial agriculture.” He added, “In this case, with drainage districts, the authority to take some steps already exists.”
U.S. Environmental Protection Agency head administrator Scott Pruitt announced on Monday that the Trump administration would begin the process of rescinding the Obama-era Clean Power Plan.
President Obama’s 2015 Clean Power Plan was designed to reduce the power industry’s carbon dioxide pollution levels by 32 percent below 2005 levels before 2030. The plan was a part of a larger effort to meet the U.S. commitment to the Paris Climate Accord, from which President Trump decided to withdraw shortly after taking office.
Gina McCarthy served as EPA administrator during Obama’s second term in office. She said in a statement, “They’re adding more pollution into our air and threatening public health at a time when the threats of climate change are growing and the costs are growing immeasurably higher on our children and their future.”
Pruitt is said to have filed his proposal to rescind the climate policy on Tuesday, but the proposal is subject to public comment for months before it is finalized. Attorneys general in New York and Massachusetts have said they will sue the administration after the repeal goes through. California and New York state have both adopted their own climate smart polices, which include emission-cutting regulations that exceed those outlined by the Clean Power Plan.
The beginning of September brought Hurricane Harvey, a category four storm which caused unprecedented damage to the U.S.’s fourth largest city, Houston. Five additional hurricanes left paths destruction across the Caribbean and Florida later in September, with Irma and Maria both reaching category five status.
It is common for September to be the most active month for hurricanes because low pressure systems often move across the Atlantic from Africa and meet the tropical waters of the Caribbean at this time, but September 2017 was a cut above the rest. According to Phil Klotzbach of Colorado State University, September 2017 featured 18 “major hurricane days,” beating 1961’s record of 17.25 “major hurricane days.” Last month, the overall intensity and duration of storms, known as “accumulated cyclone energy,” was 175 units, significantly higher than September 2014’s record of 155 units.
