The derecho and drought last year destroyed $802 million in corn, soybeans and pastures with farmers absorbing nearly one-third of the losses, according to a new report.

The American Farm Bureau Federation is lobbying congress for additional disaster aid for US growers due to insurance being unable to total cover the cost of damages. Federal crop insurance covered $560 million in losses leaving $243 million in damages farmers were responsible to pay for out of pocket. 

Across the country, damages caused by natural disasters totaled $6.5 billion last year. Federal crop insurance is only able to cover around $2.9 billion in losses with $3.6 left to farmers. Farm Bureau crop damage estimates do not include other ag losses such as loss of livestock or additional equipment costs farmers experienced. Regardless, it was the fourth-most expensive year of natural disasters since 1980, according to the National Oceanic and Atmospheric Administration

The derecho’s powerful winds reached 140 mph on August 10 as it traveled 770 miles across eight states. While most of the damages to homes, businesses and farmers centered in Iowa and Illinois, total damage reached $11.5 billion. 

U.S. Representatives Cindy Axne, D-Iowa, and Randy Feenstra, R-Iowa, voted in favor of an $8.5 billion disaster bill to provide coverage for the derecho and other high wind events which the House agriculture committee approved Tuesday according to the Des Moines Register. The bill would provide assistance to farmers and ranchers seeking natural disaster assistance for last year and 2021. 

Iowa climate scientists predicted extreme summer heat, extreme rainfall expected

In 1991, scientists accurately predicted climate change would lead to a warmer and wetter Midwest in the spring and summer. Now, 5-day heat wave temperatures in Iowa are anticipated to increase around 7° F in an average year and 13° F once per decade, in comparison to the late 20th century. 

The impact of these findings go beyond weather patterns, degraded public infrastructure is one major ways everyday life will be altered by the new climate. In 2018, a group of climate scientists and researchers from across the state focused the Iowa Climate Statement on infrastructure to emphasize their concerns. In the statement, they explain how daily total rainfall is expected to double in intensity by 2025. 

Flooding along Iowa’s eastern and western borders in 2019 alone resulted in $1.6 billion in damages, according to the Des Moines Register. “…This type of flooding in this region is expected to become even more likely in the future if we do not take immediate actions to cut greenhouse gas emissions,” said University of Iowa Researcher Wei Zhang

Scientists recommend buildings be designed to withstand heavier rain by integrating rain screens, large gutters and downspouts. For the hot summer greater insulation, improved ventilation, planting of shade trees and more are needed.

Since 2011, the Center for Global and Regional Environmental Research has co-produced an annual Iowa Climate Statement to explain the impact of climate change on Iowa. Released in early October early, nearly every Iowa college and university has agreed to the statement. 

Climate Crises Occur Around the World

Climate crises around the world are occurring. Last week Zhengzhou, China experienced catastrophic floods that accumulated the amount of rain normally expected in a year, in just 72 hours. Already 63 people have been found dead, and irreversible damage has been made on buildings, roads and houses. These floods are being called by some- once-in-a-thousand-year floods. 

China is not the only place experiencing flooding. Europe is also seeing deathly flooding in Germany, Belgium and the Netherlands. In Germany, at least 158 people are missing, and in Belgium 18 people are missing. These floods have killed at least 205 people in Europe. 

On the other end of crises, fires are rapidly destroying areas in Oregon and Canada. Oregon’s fire, which is being referred to as the Bootleg fire, is so far the third largest fire in United States history. 67 homes have been destroyed, and 2,500 people were advised to evacuate their area. 

In Canada, even more people were evacuated and entire villages have been burned. Two weeks ago, British Columbia declared a state of emergency. The wildfire smoke become so thick that many places in Canada issued air quality warnings. Those in areas not burning were still greatly affected. 

Iowa Experiences Intense Weather Patterns

Iowa crops are experiencing an intense weather pattern this summer. Despite rain over the past week, some parts of Iowa are still in need of more moisture in order to benefit crops. Some storms were so severe it ended up causing damage to crops. Iowa Secretary of Agriculture Mike Naig said that the moisture is very needed, however there were flash floods in southeastern Iowa. 

This past week the average precipitation state-wide was 2.13 inches, when the weekly average is 1.09 inches. Prior to this week, over 90 percent of Iowa was experiencing abnormal dryness, and 44 percent of Iowa was experiencing severe drought. This is a drastic change. 

Northwest Iowa has reported to have inadequate soil moisture in over two-thirds of topsoil. In the opposite part of Iowa, the southeast, 60 percent of topsoil is adequate to surplus. 

Despite the intense changes, crop conditions have been stabilized, and 60 percent of Iowa corn is in good to excellent condition. Soybeans are also blooming earlier than past years. 

Gov. Kim Reynolds has given approval for state resources to be used in order to recover from the effects of this severe weather. This can apply to qualifying individual residents who are damaged by the weather.

Biden Doubles FEMA Funding to Support Proactive Programs

Elizabeth Miglin | May 26, 2021

On Monday, the Biden administration announced plans to provide $1 billion in additional funding for FEMA in order to prepare communities for the increasingly destructive hurricane season. 

The additional funding will double the current financial size of the Federal Emergency Management Agency program which gives states and local governments money to reduce vulnerability before a disaster occurs. The majority of the funds will go to FEMA’s Pre-Disaster Building Resilient Infrastructure and Communities (BRIC) program which seeks to shift federal funding from reactive spending to proactive investment in community resilience. Additionally, a small portion of the funding will directly support disadvantaged communities. 

After years of record storms and wildfires as well as recent assignments to administer coronavirus vaccinations, many FEMA staff members are worn out. Furthermore, the increased funding is expected to cause an even larger administrative burden for FEMA. Regardless, scientists anticipate this hurricane season to be “above-normal” with as many as 10 hurricanes expected, including three to five hurricanes reaching Category 3 or higher. Climate change has caused hurricanes to become more powerful and destructive, making FEMA’s capabilities of increased focus in Washington.

In Iowa, FEMA provided more than $33 million in aid to help communities recover from the derecho which struck in August 2020. Weather patterns such as derechos’ are expected to increase over the next few years in the Midwest, resulting in decreased agricultural productivity and increased flooding and drought

New University of Iowa Research Connects Iowa Flooding to Climate Change

Climate scientists at the Iowa Institute of Hydraulic Research (IIHR) found rising greenhouse gas concentrations caused by human activity have increased the frequency of flooding in Iowa and the midwest. 

Led by IIHR researchers Wei Zhang and Gabriele Villarini (IIHR director), the study focused on the weather type known as the “Midwest Water Hose” (MWH). The MWH carries moisture from the Gulf of Mexico to the midwest where the moist air meets cold dry air from the north. More than 70 percent of total precipitation in Iowa during the first five months of 2019 is accredited to this weather system.

Results from the CMIP6 climate model used in the study showed natural climate variations were unable to explain why the MWH has been occurring more frequently over the past 40 years. However, when Zhang and Villarini accounted for rising greenhouse gas concentrations the model reproduced the increase in the occurrence of the MWH. 

Flooding along Iowa’s eastern and western borders in 2019 resulted in $1.6 billion in damages, according to the Des Moines Register. “…This type of flooding in this region is expected to become even more likely in the future if we do not take immediate actions to cut greenhouse gas emissions” said Zhang

The damage caused by floods often impacts communities for years to come. “We still are seeing the very real impacts of the 2008 flood in effect over ten years later, because of the level of damage to university and city infrastructure,” Iowa City Assistant City Manager Ashley Monroe said to the Daily Iowan

The study was published on March 1st in the scientific journal Philosophical Transactions of the Royal Society, Mathematical, Physical, and Engineering Sciences

Drought Conditions Likely To Continue Into Crop Season

Thomas Robinson | March 9th, 2021

Experts are concerned that the drought conditions currently affecting Iowa are likely to continue into the coming crop season.

According to the U.S. Drought Monitor approximately 11% of Iowa is experiencing drought conditions and most of the affected counties are in northwestern Iowa where dry conditions have persisted for most of the year.  There is hope that spring snowmelt could address some of the moisture deficit, particularly if the snow melts slowly which would allow the soil to absorb the water.  Experts believe that reliable spring rainfall could help make up for dry conditions, however, Iowa is predicted to have less spring precipitation than normal because of persistent La Niña conditions in the Pacific Ocean.

Northwestern Iowa has recently experienced tough conditions as two years of dry soils have followed the heavy flooding in the area back in 2019.  Drought conditions can induce stress in crops which may lead to damage and reduced yields for both soybeans and corn.  After a year of uncertain crop markets, another year of drought is likely bring added difficulty for Iowan farmers.

New Research Improves Early Warning of Destructive Megastorms

Nicole Welle | August 20, 2020

New scientific research will make it easier to predict the path of devastating megastorms and enable communities to better prepare for flooding.

Mesoscale convective systems (MCSs) are megastorms that affect communities all over the world. They can be bigger than the size of England and travel over 600 miles over a period of anywhere from a few hours to two days. They often cause major damage to infrastructure and livestock, and severe flooding triggered by these storms can threaten human lives. In the Sahel region of Africa, MCSs have tripled in frequency since the 1980s due to global warming, according to an article published by the UK Centre for Ecology and Hydrology (UKCEH).

Until now, it was difficult to predict the path of MCSs. However, a new study conducted by the UKCEH found that land surface conditions affect the direction and intensity of megastorms after they form.

“It is well known that heat provides thunderstorms with great energy, but it was commonly thought that once they are moving, they were not affected by the state of the ground over which they travelled. However, we found that drier soils increased the intensity of an MCS mid-storm, affecting the amount of rainfall they release and also where they travel. Conversely, we found storms were often weakened over moister soils,” said lead author Dr. Cornelia Klein of UKCEH.

This new information has allowed scientists to develop online tools to forecast the path and strength of approaching storms – a breakthrough that will increase warning times for affected communities. It may also enable better decision making by town planners and farmers at the center of MCS hotspots and increase the resiliency of their economies.

US Reaches Ten Billion-Dollar Disaster Mark Earlier Than Any Year Prior

Thomas Robinson | July 28th, 2020

As of July 8th, the US has already experienced ten weather and climate disasters where the losses exceed one billion dollars.

Billion-dollar disasters are weather or climate events that result in losses reaching, or exceeding, one billion dollars in damage costs.  In a concerning trend, the past five consecutive years have all had ten or more billion-dollar events averaging almost fourteen severe events per year.  There have been ten billion-dollar disasters so far in 2020 occurring earlier than any other year prior.   

Climate projections suggest that severe storms will increase in both frequency and intensity supporting the need for increased disaster relief funding to address the prevalence of expensive disaster clean-up.  Surprisingly, the storms responsible for almost half of the billion-dollar disasters since 1980 have been severe thunderstorms rather than hurricanes or floods.

Iowa has recently been involved in the billion-dollar disaster figure with the 2019 Missouri river floods which caused around $1.6 billion in damages.  As weather patterns become more severe, the likelihood storms reach the billion-dollar mark will increase making events like the 2019 floods more common events for Iowans.

New Flood Risk Assessment Suggests Higher Risks Than Previously Thought

Thomas Robinson | June 30, 2020

A new report from the First Street Foundation shows that flooding risk across the country is likely under represented.

New calculations reported in “The First National Flood Risk Assessment” suggest that almost twice the number of properties have a heightened flood risk compared to the FEMA Special Flood Hazard Area (SFHA) 1 in 100 layer.  The SFHA identifies properties with a heightened flood risk and influences decisions made for flood insurance and housing mortgages. FEMA identifies around 8.7 million properties to be at risk from a 100 year flood while the new risk assessment estimates 14.6 million properties to be at risk. 

To estimate the 14.6 million properties, the new report included small creeks that were ignored on federal maps, rainfall and sea-level rise.  The risk assessment includes areas where flood mapping is either incomplete or out of date which contributes to the increase in the number of at risk properties. 

For Iowa, the report suggested an additional 141,300 properties were at risk in the state compared with the SFHA measure.  The report identified Council Bluffs as the city with the most properties at risk (11,000 properties), followed closely by Des Moines (9,000 properties).
