This weeks segment highlights the affect of climate change on plant life in East Antartica.

Transcript:

There is evidence of climate change affecting moss beds in East Antarctica.

This is the Iowa Environmental Focus.

In East Antarctica, green moss beds emerge after the snow melts for 6 weeks. West Antarctica and the Antarctic Peninsula have experienced significant climate changes, but East Antarctica was yet to experience anything major.

Professor Sharon Robinson from the University of Wollongon in Australia was surprised to see abrupt changes in the moss. In 2003 the monitoring system was first set up and the moss beds were lush and bright green. When her team returned in 2008 the majority of the plants were red. The dark red color indicates the plant is stressed.

The red pigment is meant to act as sunscreen. On the team’s most recent trip to East Antarctica, there were also patches of grey moss indicating the plant is starting to die. This behavior is caused by a drying climate in the region. It is now too cold and windy for the moss beds to live primarily under water. The drier climate is a result of climate change and ozone depletion.

Reflecting on the 2018 Climate Statement

The UI Center for Global and Regional Environmental Research had a big day yesterday; we released the 2018 Iowa Climate Statement at the Cedar Rapids Public Library for the press and public. Today we can reflect on the magnitude of the statement’s message.

Titled “Designing Buildings and Communities for Iowa’s Future Climate,” the statement warns of the urgent need to adapt buildings and public infrastructure to withstand the extreme weather of tomorrow. Scientists predict that average annual heat waves will increase by 7ºF and the most extreme rainfall events will double in intensity by midcentury.

“These are really scary numbers which will have negative consequences for the elderly, the economy, for corn and soybeans, as well as beef, hogs and poultry even under sheltered confinement,” said Jerry Schnoor, co-director of CGRER. “We must start now to adapt our built environment, including buildings and flood mitigation systems, to this changing climate.”

Schnoor presented the statement yesterday with Associate Professor of Architecture Ulrike Passe, director of Iowa State University’s Center for Building Energy Research.

“Water will also enter buildings from the foundation or basement walls,” Passe said. “In particular, heavier rain events and higher water tables affect foundations, and standards going forward must reflect that.”

She provided examples of several adaptations that can be made to buildings to prepare them for increased heat and precipitation, including steeper roof slopes, increased insulation and better ventilation. She said Iowan communities should consider managing increased rainwater runoff with green, vegetation-based infrastructure like rain gardens and urban forestry as well.

These adjustments need to be made as soon as possible; Iowa’s weather is already feeling the effects of climate change.

“Warming over the Gulf of Mexico is helping feed large rain events in Iowa and the Midwest,” Schnoor said. “That’s why we’re prone to intense downpours and major flooding like Des Moines saw on June 30 and like eastern Iowa has been experiencing for the past six weeks. People’s homes and businesses are being flooded that have never been flooded before.”

Burning less fossil fuel and reducing atmospheric carbon emissions can help mitigate climate change’s impacts as well, but at this stage, adaptation is absolutely crucial. We at CGRER hope those with decision-making power take the statement to heart, and listen to the record 201 science faculty and researchers from 37 Iowa colleges and universities who endorsed it.

Clive, IA: $1.25 million buyout for flooding protection


Kasey Dresser | October 1, 2018

City officials of Clive, IA have approved a buyout for home and business owners affected by the June floods. The buyout will focus on properties affected in Walnut Creek and North Walnut Creek.

“We have dangerous flash floods on Walnut Creek and North Walnut Creek, and the frequency and intensity of that flooding is increasing,” said Clive City Manager Matt McQuillen.  “The properties we’re targeting have been flooded multiple times in the past decade.  In this case, the most effective way to protect lives and property from future loss is to remove the buildings and improve the natural floodplain function.”

City taxes will not be increased to purchase the properties. City council members will continue to discuss flood mitigation and preparedness strategies for the future.

Applications from property owners in the acquisition area must be submitted by November 5, 2018. Additional information about property criteria can be found here or at the City of Clive website.

Marshalltown, IA continues to struggle after tornado in July

Debris still in the streets

Kasey Dresser | September 12, 2018

On July 19th of this year, Marshalltown, IA was hit with a devastating tornado. 89 homes were destroyed and 525 sustained major damage. The  tornado struck a low income part of town making it very difficult for the small town to bounce back. Many people in the area had little to no insurance.

Lennox and JBS Swift & Co., the two largest employers have made sizable donations to help rebuild property. With disaster relief help, several employers have been able to continue to provide health insurance to their employees despite no longer having jobs for them. However, the process is slow and there are many people in the town still living in destroyed homes despite the tornado occurring months ago. Marshall County Family Long Term Recovery Committee is currently going door to door to evaluate which homes can still be lived in long term. Greg Smith, chairman of the Iowa Disaster Human Resource Council, stated, “It is not unusual for the poorest of the community to become poorer after a disaster.”

There is also large concern from business owners they may not have the insurance money to rebuild their company. It is a city requirement to use the original materials instead of replacing it with something cheaper, like wood. The collapse of these business will leave many people unemployed.

Even after the physical damage is cleared away Marshalltown will likely face a difficult couple years. Jim Zaleski, the city’s economic development director and tourism marketer, has helped with tornado relief in other towns. He believes,” the tornado was a catalyst, ” and will “force the community to take some hard looks at what was going to happen over the next decade.”

Heavy flooding expected in Cedar Rapids

The Cedar Rapids area is currently under river flood warning. The Cedar Rapids River is expecting to crest at 16.5 feet midday Thursday. The crest is the highest point of a flood wave. For reference, Cedar Rapids’ last flood was in 2016 and crested at 22 feet. The devastating 2008 flood crested at 31 feet.

Mayor Brad Hart held a press conference yesterday stating that preparations were in place. City workers are preparing for 18 feet to be safe. Hart stated, “I’m confident that no matter how high the river gets this week, that we’ll rise above it and protect the community as best we possibly can.”

Right now there is expected to be no damage. City Public Works Director Jen Winter’s biggest concern is “water coming back into our storm sewer system and backing up.” “Unless something fails, we anticipate that no, that there would not be damage,” she said. “In some cases, depending on the age of a building, some people do get water in their basements despite the fact that we have kind of plugged off the river from backing up.”

A visit with Dr. James Hansen about his work


Kasey Dresser | May 2, 2018

The University of Iowa was very lucky to receive a visit from scientist, researcher, and adjunct professor Dr. James Hansen. He was gracious enough to sit down with us and interview about his work, education, and relationship with Dr. James Van Allen.

Hansen was trained in astronomy and physics under Dr. Van Allen at the University of Iowa, graduating with the highest distinction in 1963; he then published his dissertation on Venus and helped launch the Pioneer Venus project in May of 1978. Hansen was the head of the NASA Goddard Institute for Space Studies in New York from 1981 to 2013. Today, he continues his work on climate change as the director of the Program on Climate Science at Columbia University’s Earth Institute, and gave a TED talk on climate change in 2012.

This video, discussing his work, will be the first of a 3 part video series. Tomorrow, Dr. Hansen will speak directly to students and the following day will focus on his relationship with Dr. Van Allen.
