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.
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 2017 Water Year came to an end recently according to a report from the Iowa Department of Natural Resources (DNR).
The “water year” runs from September 30th through October 1st. Overall, the 2017 water year has been drier and a bit warmer than usual. The statewide precipitation average was about 32 inches, which is roughly 3.28 inches less than usual. Precipitation was around average during the winter months, but fell below normal during the summertime.
Temperatures in the state averaged 50.7 degrees Fahrenheit, which made 2017 the fourth warmest year on the Iowa DNR’s 144 year record. While temperatures were mostly typical during the growing season, they were higher than usual for most of the winter months. This year brought the second warmest November and the third warmest February on record.
Human-induced climate change costs more than the U.S. economy can afford according to a recent report from the Universal Ecological Fund.
“The Economic Case for Climate Action in the United States,” published recently by the non-profit research organization, found that severe weather intensified by climate change and the health impacts associated with burning fossil fuels have cost the U.S. economy $240 billion per year in the last decade.
Economic losses due to extreme weather have doubled in the last ten years. To illustrate this point, the authors point out that Hurricanes Harvey, Irma and Maria caused an estimated $300 billion in damages, which is double the $145 billion in losses caused by all hurricanes in the last decade.
The press release points out that the number of extreme weather events costing $1 billion or more in damages has increased by 400 percent since the 1980s. Iowa, for example, has endured three floods costing more than $1 billion in the last decade, up three fold since the 1990s.
If climate change is not curtailed, researchers predict annual costs associated with severe weather and the health impacts of greenhouse gases will reach $360 billion.
Sir Robert Watson, coauthor of the report and former Chair of the Intergovernmental Panel on Climate Change said during a press conference, “Simply, the more fossil fuels we burn, the faster the climate continues to change and cost. Thus, transitioning to a low-carbon economy is essential for economic growth and is cheaper than the gigantic costs of inaction.”
