Just weeks after July 2019 became the hottest month in 140 years of recordkeeping, 216 science faculty and researchers from 38 Iowa colleges and universities have endorsed the ninth annual Iowa Climate Statement 2019: Dangerous Heat Events to Become More Frequent and Severe.

The statement, released on September 18, warns Iowans and Midwesterners of sobering extreme heat projections for the region. Based on the most up‐to‐date scientific sources, the statement makes clear the urgency of preparing for dangerously hot summers in the coming decades.

Betsy Stone, Associate Professor in the Department of Chemistry at the University of Iowa, reads this year’s statement in the video above. Access the full written statement here.

 

Why is action on climate change more important than ever before?

The Iowa Climate Statement 2019: Dangerous Heat Events to Become More Frequent and Severe was released yesterday at press conferences in Des Moines and Cedar Rapids.

Yesterday, at the Cedar Rapids Press Conference, Dr. Jerry Schnoor was asked what he would say to individuals that do not currently see climate change as a major issue. 

This year’s statement warns Iowans and Midwesterners of sobering extreme heat projections for the region. Based on the most up-to-date scientific sources, the statement makes clear the urgency of preparing for dangerously hot summers in coming decades.  The statement describes some of the sobering impacts of hotter heat waves and more hot days. The 9th annual Iowa Climate Statement was endorsed by a record 216 science faculty, researchers and educators from 38 Iowa colleges and universities.

On March 15th across the nation, youths gathered to raise awareness for climate change and its effect on our world. In the Ped Mall in Iowa City, over 50 students from Southeast Jr. High gathered to speak to the community about their concerns.

The students came prepared with a bullhorn and took turns sharing their opinions for two hours. They were holding hand made signs and handing out a sheet of climate change facts. While young, the passionate students created quite an audience stating, “the bigger the fuss we make, the more politicians will listen.” Congressman Dave Loesback was present and talked with the students in his office following the event.

From the climate change fact handout:

  • 408 parts per million. The concentration of carbon dioxide (C02) in our atmosphere, as of 2018, is the highest it has been in 3 million years.
  • 800 million people or 11% of the world’s population is currently vulnerable to climate change impacts such as droughts, floods, heat waves, extreme weather events, and sea-level rise.
  • Thermometer records kept over the past century and a half show Earth’s average temperature has risen more than 1 degree Fahrenheit (0.9 degrees Celsius), and about twice that in parts of the Arctic.
  • We have 11 years to reverse the effects of climate change. We must act now.

An analysis of early farming practices

A study from the University of Wisconsin- Madison theorizes how agriculture would have affected the climate without the Industrial Revolution.

According to the Early Anthropogenic Hypothesis, early farming practices produced mass amounts of carbon dioxide and methane. Without the presence of the industrial revolution ancient agriculture would have trapped enough methane in the atmosphere to create a similar state of climate change.

The Early Anthropogenic Hypothesis was originally developed by William Ruddiman, a paleoclimatologist at the University of Virginia 15 years earlier. The climate reconstructions are based on ice core data. Our current geological time frame is called Holocene and the one before is referred to as MIS19. Both time periods started with similar carbon dioxide and methane concentrations based on evidence from ice core data. MIS19 saw a steady drop in greenhouse gasses. The numbers have since spiked to our current state of emissions. The data currently stops at the start of the Industrial Revolution but people are continuing to develop the hypothesis.

Stephen Vavrus, a senior scientist on the project concludes, “science takes you where it takes you,” and “things are so far out of whack now, the last 2,000 years have been outside the natural bounds. We are so far beyond what is natural.”

The University of Iowa’s new Sustainable Water Development graduate program goes beyond science and engineering to give its “trainees” a holistic understanding of food, energy, and water.

The program is in its first year with a class of 17 students from around the country with a vast array of career goals. Coursework employs several different disciplines, like entrepreneurship and health in addition to science and engineering.

“I’m excited to think that when I’m finished here, I won’t just be an engineer — I’ll be a scientist, a budget expert, and a public health expert. I’ll definitely be better prepared for whatever the world throws at me,” Amina Grant, a student in the program, said to Iowa Now.

The National Science Foundation Research Traineeship awarded a $3 million grant to the UI to start this program in 2016. Program director David Cwiertny believes the multidisciplinary proposal and the opportunities the state provides made Iowa the best choice for the grant.

“The state really does feed the world,” Cwiertny said to Iowa Now. “Iowa is also a leader in wind energy and is dealing with important water quality issues. This makes the state the perfect place for a training program for professionals who want to address water, food, and energy issues.”
