Josie Taylor | October 13, 2021

Since 2011, researchers and educators at nearly every college and university in Iowa have produced annual statements to communicate in plain language the state of climate science and the impacts of climate change on Iowans. Today, the Climate Statement for 2021 was released. This year’s focus is on Iowa’s Electric Infrastructure.

Last year’s August derecho, the most destructive thunderstorm in US history, knocked out power to more than 500,000 Iowa households for as much as two weeks. “The loss of power left people in the dark without air conditioning, refrigeration, access to food, phone chargers and life sustaining medical equipment,” said Dave Courard-Hauri, Chair of Environmental Science and Sustainability Program, Drake University. “This was a potentially deadly combination for many vulnerable and low income Iowans.”

“Iowa’s power outages from the 2020 derecho resulted from extreme damage to transmission and distribution systems,” said Jim McCalley, Anson Marston Distinguished Professor, Department of Electrical and Computer Engineering, Iowa State University.

Climate disasters are not over. To prepare for future Iowa extreme weather events, it is recommended that industry, policy makers and stakeholders identify ways to strengthen Iowa’s electric infrastructure, protect vulnerable people, and consider enhanced risks from climate change while managing costs. Climate change is here. We need a resilient electric infrastructure as we curtail carbon emissions for a more sustainable future.

In 2019, Iowa climate activists were concerned about the frequency and severity of dangerous heat events. Through the Iowa Climate Statement two years ago, signatories informed Iowans they would be seeing more extreme weather disasters in coming years.

The statement focused on the Earth’s surface continuing to warm at an unprecedented rate, as recent years continually breaking records for the hottest years on record. Hundreds of Iowans signed the climate statement, agreeing that Midwesterners ware seeing dramatic changes in weather with changing rainfall, higher humidity, and warmer nights. Many homes in lower-income areas across the U.S. were not equipped with air conditioning units, leading to more incidents of heat stroke and potential fatalities.

The 2019 Iowa Climate Statement suggested adaptions to these increasingly severe and frequent heat events would require more preparedness, increased energy usage to cool houses and buildings, changing livestock facilities, and halting outdoor work in extreme heat conditions.

Two years later, heat remains the leading cause of weather-related deaths. Another concern from 2019 that remains is the risk to animals with increasing temperatures. Hogs, cattle, and poultry are essential to Iowa’s agricultural industry and the animals continually are at risk of dying from extreme heat events alongside human beings.

Iowa has seen record-breaking heat waves in the past few months. Heat advisories were administered across the country, including in the Midwest where Iowa, Missouri, and Illinois saw several days where temperatures ranged in the 100s. Concerns regarding dangerous heat waves continue in Iowa as they become more frequent and severe, as predicted by the Iowa Climate Statement in 2019.

Iowa Climate Statement 2021 will be released on Wed. Oct. 13.
The eleventh annual Iowa Climate Statement 2021: Strengthening Iowa’s Electric Infrastructure will be released on Wednesday, October 13, 10:15 am at a Zoom press conference and live on CGRER’s Facebook page. The lead authors of the statement will present the statement and take questions. 

Revisiting Iowa Climate Statements: A Rising Challenge to Iowa Agriculture

Eleanor Hildebrandt | October 8, 2021

One of the biggest climate issues facing Iowans eight years ago was the rising green house gas emissions according to the 2013 Iowa Climate Statement.

While this is still a major concern, dozens of people signed on to the 2013 Iowa Climate Statement. The statement discussed how green house gas emissions and climate change were disrupting Iowa agriculture. Following two years of massive droughts, Iowa saw the one of the wettest summers in the state in 2013. The constant extreme weather in Iowa threw the agriculture sector for a loop. Climate change also causes an increase in soil erosion alongside intense rain events and droughts in Iowa. This leads to degraded agricultural production across the state.

In 2021, Iowa saw a severe drought across the state throughout the summer months. Extreme weather events continue to cause stress to plants and crops across the board. Both climate change and green house gas emissions still concern Iowans and climate activists across the globe.

Iowa Climate Statement 2021 will be released on Wed. Oct. 13.
The eleventh annual Iowa Climate Statement 2021: Strengthening Iowa’s Electric Infrastructure will be released on Wednesday, October 13, 10:15 am at a Zoom press conference and live on CGRER’s Facebook page. The lead authors of the statement will present the statement and take questions.

This past September was the 15th wettest September on record for Iowa, according to the Iowa Department of Natural Resources. This has been able to remove drought locations that happened over the dry summer months.

Iowa’s average rainfall amounted to 6.17 inches — 2.79 inches above normal for September. The temperature average to 68.2 degrees, making it the ninth warmest September on record. While it has been able to offset drought damage, the DNR stated in a press release that saturated soils make the state vulnerable to flooding if rainfall continues.

The National Oceanic and Atmospheric Administration found that June 2018 to May 2019 were the wettest 12 months on record for Iowa since 1895. Iowa received extreme flooding in the spring from the Missouri River. Early snow melt from not only Iowa, but also South Dakota and Minnesota, contributed to the rising water levels in the river.

Iowa also received heavy rainfall, which some reports attributed to a changing climate and warm ocean temperatures. In the June to May time frame, Iowa received 50.73 inches of rain.

Effects of the changing climate in Iowa were seen into the summer months. The Iowa Climate Statement was released Sept. 18, which outlined trends in temperatures and how Iowa can expect more 90 degree days in a year. The report also serves as a warning to Iowans and Midwesterners to expect extreme heat, and provides guidelines on how one can properly prepare.

 

Researchers speak at statehouse about rising temperatures

Tyler Chalfant | September 24th

Professors from Iowa universities spoke at the statehouse last Wednesday, Radio Iowa reported. The 216 climate educators who issued the ninth annual Iowa Climate Statement represent 38 colleges and universities in the state. 

This year’s statement warned of the increased intensity and frequency of heat waves that Iowa will experience in the coming decades. The group projects that the number of days exceeding 90 degrees will more than double within the next two decades, and nearly triple by mid-century.

The scientists spoke about how these increased temperatures will put Iowans at greater risk of heat related illnesses, including heat exhaustion, heat cramps, heat stroke, or death. Scientists have predicted that rural areas will likely be hit the hardest by rising temperatures, and that the Midwest will see the greatest number of premature deaths caused by heat. 

Peter Levi, an Environmental Science professor at Drake University, said that those facing the most danger “include our friends and neighbors who work outside on a regular basis, older adults above age 65, infants and children, those individuals with chronic conditions, low-income households and our athletes.” 

Levi also said that extreme heat will harm the state’s livestock industry, as confined livestock are at increased risk of death, and won’t reach a marketable weight as quickly when stressed by high temperatures. 


“It’s not hopeless,” added Bill Gutowski, an Atmospheric Sciences professor at Iowa State University, indicating that there is still time to reduce greenhouse gas emissions. “I want people to realize it’s not hopeless and there are adaptations that we can do as well.”

Today top Iowa climate scientists released the Iowa Climate Statement 2019: Dangerous Heat Event Will Become More Frequent and Severe, warning Iowans and Midwesterners of the serious heat-related dangers the climate crisis is creating in our region.

Read the full statement here. Watch the press conference here.

The report has been backed by 216 faculty and researchers from 38 Iowa colleges and universities. Based on the most up‐to‐date scientific sources, the statement makes clear the urgency of preparing for dangerously hot summers in coming decades.

Highlights from the statement 

  • By midcentury, temperatures in Iowa will exceed 90 degrees Fahrenheit 67 days per year, compared to a 23‐day average in recent decades.
  • By midcentury, the average daily high temperature for each year’s hottest five‐day period will be 98 degrees, compared to 92 degrees in recent decades.
  •  Once per decade, five‐day average high temperature will be 105 degrees.
  • Extreme heat is the leading weather‐related cause of death in the U.S.. Low‐income neighborhoods, the elderly, outdoor workers (especially construction and farm labor) and domestic animals are especially vulnerable.
  •  Confined livestock are at increased risk for death and widespread productivity loses. Producers will need to adjust their operations to deal with extreme heat events.
  • Adaptations to increasing heat waves will require expanded disaster preparedness, increased energy use and curtailment of outdoor work and recreation during times of extreme heat.

The UI Center for Global and Regional Environmental Research has released annual climate statements since 2011. These statements, vetted by Iowa’s top experts, place pivotal climate change research into an Iowa‐specific context, encouraging preparedness and resilience in the face of a climate crisis.

We already know climate change is having major impacts on rainfall. The 2018 Iowa Climate Statement said the strongest rainfall events of the year may double in intensity by 2025.  Climate change will alter the hydrologic cycle in other ways as well, majorly changing society’s relationship with water.

The Fourth National Climate Assessment, controversially released Black Friday, details the forecasted changes to water supplies in the U.S.. It compiles the findings of over 300 experts and has been reviewed by 13 federal agencies, in an effort to inform top decision-makers and common citizens.

More intense rainfall will be met with more intense drought and reduced snowpack, which is bad news for communities that rely on glacial melt for their water supply. These changes are exacerbating water availability issues caused primarily by overuse of groundwater aquifers in much of the U.S..

As higher temperatures create even higher demand for water for drinking and irrigation, this problem will only get worse and worse, which will have major implications for both the food supply and the industrial sector.

The altered hydrologic cycle will impact the quality of our limited quantity of water as well. Rising water temperatures will impact the health of ecosystems, and changes  runoff patterns of pollutants into water will impact human health and pose challenges for water treatment facilities. Sea level rise could also threaten coastal drinking water supplies with the potential intrusion of saltwater flooding.

The report says the biggest water issues for the Midwest are adapting stormwater management systems and managing harmful algae blooms. Iowa is already familiar with floods produced by intense rainfall.  Algae blooms, fueled by nutrient-runoff from farm fields, will be further increased by rising temperatures.

Other water-related challenges detailed in the assessment include the deterioration of water infrastructure and managing water more strategically in the future.

 

Extreme rain causes record-setting delay for Iowa soybean harvest


Iowa Widespread Extreme Rainfall_August 26_October_10_2018
This map from Iowa Environmental Mesonet shows the extent of rainfall in Iowa this fall. These conditions have contributed to a delayed soybean harvest. 

Julia Poska | October 19, 2018

Last week, Iowa saw up to four inches of rain rain, below-average temperatures, and 10 confirmed tornadoes. The unfavorable weather has made this year’s the slowest Iowa soybean harvest on record.

As of Oct. 14, Iowa farmers had only harvested 14 percent of soybean acres in the state. , according to last week’s Iowa Crop Progress & Condition Report, put out by the National Agriculture Statistics Service. The report said that between the cold, rain and even snow, only 0.8 days during the week were suitable for fieldwork.

At this time last year, about 30 percent of Iowa soybeans were off the field. In 2016, that number was closer to 50 percent.  The 2018 Iowa Climate Statement, released last week, warns that extreme rainfall events will only get worse in Iowa as time goes on. Future years may see even later delays for harvests.

Despite the slow harvest, the bean plants themselves are a bit ahead of schedule. The report said 97 percent of the soybean crop was dropping leaves as of the 14th, five days ahead of average. Wallace’s Farmer reported that in some fields, moisture has prompted beans to start sprouting out of their pods.

Ideally, the beans only contain 13 percent moisture at harvest, but these wet conditions could cause the beans to absorb and store more water from the air, according to South Dakota’s Capital Journal. This could spell bad news for farmers, as many buyers only take dry soybeans. Farmers will have to wait longer to harvest or store their beans long-term.

Dryer conditions this week should have provided some opportunity for farmers to catch up. Meanwhile, states in the eastern Corn Belt are reporting faster-than-average harvest, according to Wallace’s Farmer.

 

 

On The Radio – 2016 Iowa Climate Statement

Jake Slobe | October 10, 2016

This week’s on the radio discusses the sixth annual Iowa Climate Statement. The full statement can be found here.

Transcript: The sixth annual Iowa Climate Statement was released on October fifth.

This is the Iowa Environmental Focus.

The document, titled Iowa Climate Statement 2016: The Multiple Benefits of Climate-Smart Agriculture, was signed by 180 science researchers and faculty from thirty-eight Iowa colleges and universities. This year’s statement centers around Secretary of Agriculture Tom Vilsack’s U.S. Department of Agriculture Initiative “Building Blocks for Climate-Smart Agriculture.” Vilsack’s initiative aims to expand nation-wide voluntary, incentive-based programs for farmers to combat human-induced climate change.

The climate statement champions proven conservation techniques such as planting perennial plants on marginal cropland and reduced-till or no till farming that would decrease nation-wide net emissions and increase carbon storage in soil. Statement authors note that the document is part of a larger effort, strengthened by the December 2015 Paris Climate Agreement, to offset human-caused climate change.
