In his environmental encyclical titled Laudato Si or “Our Common Home,” Pope Francis, called for the citizens of the world to reduce carbon emissions and become better stewards of the Earth. Now, about two years later, people of faith in Iowa are answering the call.

St. John the Apostle Catholic Church of Norwalk, Iowa has become the first church in the Diocese of Des Moines to transition to a solar energy system. The church boasts 206 energy panels, which were funded through a for-profit company. The company sells energy back to the church at a lower rates than before.

During the encyclical public address, Pope Francis said, “Never have we so hurt and mistreated our common home as we have in the last 200 years.” Last May when President Trump visited Vatican City, the Pope gave him a copy of the 192 page document on climate change.

It’s not just Catholics moving to mitigate some of the effects of global warming. The Des Moines Register reports that a Soto Zen Buddist temple in Dorchester, Iowa now gets half of its energy from solar. Mennonites in Kalona have established a solar energy system, too.

Rev. Susan Hendershot Guy is executive director of Iowa Interfaith Power & Light, a group working to mobilize people of faith to combat climate change. She said to the Des Moines Register, “It’s exciting to me because I feel like they’re sort of walking the walk. I think it is getting out to all types of denominations, congregations, faith traditions really across the conservative-liberal spectrum.” She continued, “It’s a really practical way to live out that message of how we care for the world.”

On The Radio – August water summary update released

This week’s On The Radio segment discusses how August rain relieved some parts of Iowa from drought conditions. 

Transcript: Rainfall during the last part of August helped to reverse drought conditions in many parts of Iowa, according to the latest Iowa Department of Natural Resources Water Summary Update.

This is the Iowa Environmental Focus.

The Water Summary Update is a succinct monthly report of Iowa’s water resources and those events that affect them prepared by the technical staff at Iowa DNR in partnership with local, state and federal agencies.

The latest update revealed that while August started off very dry, high rain totals increased groundwater levels and streamflow in many parts of the state. In contrast, south central Iowa is still experiencing severe to extreme drought conditions. Extreme drought conditions persisted in Clarke county and Wapello county through August.

Warming climate produces more toxic algae

There has been an increase in harmful algal blooms worldwide and in Iowa in recent years, and climate change is adding to the problem.

A recent analysis from Climate Central points out that warmer waters make conditions favorable for toxic algae to grow faster than other beneficial varieties. Toxic algae then accumulates, making the surface of bodies of water appear darker in color. This creates a positive feedback loop. The report explains, “water made darker by the presence of the blooms absorbs more sunlight, warming even more, and enhancing the conditions for more blooms.”

Heavy precipitation is another by-product of a changing climate and is becoming increasingly common in the U.S. and Iowa, specifically. Increased rainfall means that more agricultural fertilizers, which include nitrate and phosphorus, are washed off the land and into waterways. These nutrients feed algae and encourage its growth.

Ingesting harmful varieties of algae in water or on contaminated fish can cause gastrointestinal problems, respiratory symptoms, and skin irritation.

Iowa farmers face low yields, low prices

Nearly half of the state is in a drought this summer, and Iowa farmers are struggling to make ends meet.

A Des Moines Register report showed thousands of Iowa farmers are not seeing enough rain this summer, while crop prices remain low and farm income continues to trend downward. Corn and soybean prices are down 10 percent from July, and this year, farm income is expected to fall $62 billion nationwide.

“The drought isn’t widespread enough to push up prices,” Charles Brown, an Iowa State University farm management specialist said to the Register. “It’s the worst-case scenario — low prices and low yields.”

Some farmers have crop insurance to cover their losses, but often, it’s not enough. Many rely on savings to get them through after a tough year.

The drought is also drying up pastures, eliminating a dependable food source for cattle. Some farmers use hay to supplement the animals’ diets. And if a farmer’s crop has a low yield unworthy of harvesting, the farmer may choose to chop it into animal feed instead of trying to sell it.

There is still time for rainfall to improve the outlook for Iowa farmers’ crops this season, however, some are losing hope.

“People get frustrated. They throw up their hands and don’t do anything,” Brown said to the Register. “But now isn’t the time to procrastinate. [Farmers] need to get a plan together.”

Wetland project aims to reduce nutrient flow to Des Moines

Storm Lake, Iowa has completed a project to improve its water quality. Eight more projects are in the works to continue this effort.

Storm Lake, in Buena Vista County, was one of several communities involved in the Des Moines Water Works lawsuit in January. The water utility attempted to sue Buena Vista county and two other northern Iowa counties for allowing nitrate pollution in the water, which flows downstream to the Des Moines area. The Iowa Supreme Court did not side with the water utility, but the lawsuit brought attention to the issue, and Storm Lake is addressing it.

In May, the community constructed a $175,000 wetland, and last week, Iowa Gov. Kim Reynolds and Lt. Gov. Adam Gregg joined Storm Lake leaders in celebrating the step towards healthier water.

“Storm Lake has been very active over the past several years in working with storm water to improve water quality and to slow down the flow to reduce flooding in our neighborhoods, as well as reduce the nutrient loading that’s in the water,” Jon Kruse, mayor of Storm Lake, said to KWWL.

The wetland naturally removes nutrients from the water, reducing the amount of nitrogen and phosphorous flowing down the Raccoon River to Des Moines, and to the Mississippi River into the Gulf of Mexico. Nutrient removal from water can be complicated, and high levels of nutrients can cause algal blooms in water bodies, leading to low oxygen levels which are dangerous for aquatic life. Storm Lake has also had issues with flooding in the past, and this wetland should help reduce that.

On The Radio – Linn County joins national coalition committed to Paris Climate Agreement

This week’s On The Radio discusses how Linn County supervisors voted unanimously to join the We Are Still In coalition.

Jenna Ladd| August 14, 2017

Transcript: Linn County recently pledged its support for the Paris Climate Accord.

This is the Iowa Environmental Focus.

Despite President Trump’s plan to withdraw from the international climate agreement, more than 1,200 mayors, governors, college and university leaders, businesses, and investors have formed a coalition committed to combating climate change. The group is called the We Are Still In Coalition and makes up more than $6 trillion of the U.S. economy.

The Linn County Board of Supervisors voted unanimously last month to join Iowa City, Johnson County, Des Moines and Fairfield in their effort to reduce greenhouse gas emissions by 28 percent by 2025. Grinnell College, Iowa State University, Coe College and the University of Iowa are all members of the coalition.

Following the board’s vote, local officials, environmental experts and businesses including PepsiCo’s Quaker Oats of Cedar Rapids discussed plans for continued climate action.

Federal report says climate change is real and human-caused

Katelyn Weisbrod | August 10, 2017

A draft report under review at the White House says climate change is “extremely likely,” and over half of the world’s recent temperature rise has been caused by human activity.

The report, called the Climate Science Special Report, was authored by numerous federal employees and representatives from universities and private organizations. It highlights several climate-change-related phenomena, such as sea level rise, extreme weather events, glacial melting, and global temperature rise.

Members of the Trump administration have often claimed the cause of climate change is uncertain, and cannot be directly linked to human activity. However, this report claims with high confidence that most of the observed climate changes over the last half century have been caused by humans, and very little of the change is natural.

Even if humans were to stop emitting greenhouse gases immediately, the report says, the Earth would still warm at least another 0.5 degrees Fahrenheit.

“The magnitude of climate change beyond the next few decades depends primarily on the additional amount of greenhouse gases emitted globally, and on the sensitivity of Earth’s climate to those emissions,” the report says.

The Washington Post says it is still unclear what the Trump administration will do with this information. The administration may choose to disregard the report completely, like the 2000 Climate Science Special Report, which was deemed flawed under the Bush Administration, and was not cited in future reports.
