This week’s On the Radio segment looks at the Iowa DNR’s 2013 Greenhouse Gas inventory, which shows that Iowa’s agriculture industry is now the leading contributor to greenhouse gas emissions for the state. Listen to the audio below, or continue reading for the transcript.

Agriculture is now the number one contributor to greenhouse gas emissions in Iowa.

This is the Iowa Environmental Focus.

The Iowa Department of Natural Resourcesʼ 2013 Greenhouse Gas inventory report
found that Iowaʼs agriculture industry contributes to 27 percent of the stateʼs
greenhouse gas emissions.

The figure is due in part to Iowaʼs increasing dependence on wind energy, which has
drastically decreased the need for coal use over the last decade and brought emissions
from electric power generation down to 25 percent.

Greenhouse gas emissions from agriculture include those from animal digestive
systems, plant fertilizers and agricultural runoff. The most common of these gases are
methane and nitrous oxide.

Although agricultural emissions increased last year, Iowaʼs total emissions have now
decreased for three straight years.

This week’s On the Radio segment looks at an assessment of Iowa’s wind energy industry that shows the state still leads the nation in percentage of wind energy production. Listen to the audio below, or continue reading for the transcript.

Transcript: Iowa Wind

With over 3,400 turbines, Iowa maintained its third-place ranking in wind energy generation last year.

This is the Iowa Environmental Focus.

The American Wind Energy Association recently released fact sheets for each state,
showing that Iowa sits behind only Texas and California in wind projects added as of last year. Iowa still leads the nation in energy percentage from wind, with 27 percent,
resulting in a wind capacity of over 5,000 megawatts. Thatʼs enough to power nearly 1.5
million homes.

Even with those gains, the Association estimates wind power could meet
the stateʼs electricity needs forty times over. Iowa has one of the largest turbine
manufacturers in the country and two of the largest blade manufacturers.

The report shows that thanks to wind, Iowa avoided over 9 million metric tons of CO2
emissions and saved over 3 billion gallons in water usage.

President Obama signed an executive order on Thursday calling for the federal government to reduce greenhouse gas emissions by 40 percent compared to 2008 levels over the next decade. The order also calls for renewable energy sources to make up 30 percent of total electricity consumption over the same period. The plan is expected to save taxpayers $18 million in electricity costs.

“We thought it was important for us to lead by example,” Obama said in an interview with the Associated Press. “These are ambitious goals, but we know they’re achievable goals.”

The Obama administration hopes that this decision will serve as a model for encouraging other nations to deal with the effects of climate change. Other nations are expected to set similar carbon emission and renewable energy goals as part of a global climate treaty to be finalized in December.

According to the most recent data available, the federal government contributed to less than one percent of the nation’s greenhouse gas emissions in 2013. Obama also lauded efforts made by private sector companies such as General Electric, IBM, and Northrup Grumman which have taken voluntary steps at mitigating the effects of climate change.

This announcement comes on the heels of last month’s budget proposal for fiscal year 2015 which calls for a 7 percent increase in funding for clean energy and $4 billion to encourage further reduction in power plant emissions.

Climate change denial is a turnoff to voters, poll finds

Voters are overwhelmingly less likely to vote for a candidate who calls climate change a “hoax,” according to a recent poll.

The survey, conducted by The New York Times, Stanford University and research group Resources for the Future, gathered opinions from voters related to climate change and politics. It found that an overwhelming majority of voters believe global warming will pose serious problems for the country if nothing is done to curb it, and that Americans are more likely to vote for a candidate who takes climate change seriously. In addition, 78% of respondents, including 60% of self-identified Republicans, agreed that the federal government should act to limit the amount of greenhouse gases emitted by U.S. businesses.

Of note were the responses provided by Republicans, which indicate a shift away from outright climate science denial. While 48% of Republicans were more likely to vote for a candidate who said, “I believe that global warming has been happening for the past 100 years, mainly because we have been burning fossil fuels and putting out greenhouse gasses,” the same number, 48%, were less likely to vote for a candidate who said, “The science on global warming is a hoax and is an attempt to perpetrate a fraud on the American people.” However, politicians who use the “I’m not a scientist” line, an attempt at a non-answer, also scored favorably among Republicans, with 37% saying they would be more likely to vote for a candidate who used similar language regarding climate change.

This comes after a U.S. Senate resolution on climate science passed 98-1, stating that “climate change is real and not a hoax.” Challenges persist, however, in convincing Senate members that human activity causes climate change, with members split about evenly at 50-49. This led a panel of Iowa scientists to publish an editorial in The Des Moines Register further clarifying the general consensus among climate scientists: “We know humans, by adding greenhouse gases to the atmosphere, have altered the climate.”

This week’s On the Radio segment looks at the environmental work of Dubuque, which was recently named a Climate Action Champion by the White House. Listen to the audio below, or continue reading for the transcript.

Transcript: Dubuque recognized by White House.

A city in Iowa was recently recognized by the White House for its efforts to address climate change.

This is the Iowa Environmental Focus.

Dubuque was named a Climate Action Champion by the White House for efforts the city has made to reduce greenhouse gas emissions, aiming to have emissions 50 percent below 2003 levels by 2030. The city is also being rewarded for its flood conscious infrastructure and flood mitigation efforts.

Dubuque – which sits along the Mississippi River – has been declared a presidential disaster zone six times in the past 16 years. Next fall the city will begin a 179-million-dollar flood mitigation project to protect some of Dubuque’s most developed and flood susceptible areas.

As a Climate Action Champion, Dubuque will be eligible for federal funding and other resources for applicable projects.

When it comes to climate change information, farmers trust scientists most

The best way to reach farmers and agricultural workers who are skeptical of human activity’s effect on climate change may be direct connections to climate scientists, according to one Iowa State University sociologist.

A 2012 survey conducted by ISU’s J. Gordon Arbuckle Jr. found that 66% of Midwest farmers believe climate change is occurring, yet the respondents were mixed on whether or not human activity played a role. More than half said climate change either occurs naturally or is equally affected by human and natural factors. Only about 10 percent agreed that “climate change is occurring and it is caused mostly by human activities.”

Some of that skepticism may come from a general distrust of the mainstream media; the MSM was listed as the least trusted source of environment-related information. Given farmers’ dependence on scientific advances in crop development, it’s not surprising that the most trusted source of environmental information was scientists themselves.

This has important implications for anyone discussing climate change with agricultural professionals. In an interview with ClimateWire, Arbuckle recommended using language of adaptation to unpredictable weather events over explicit mentions of greenhouse gas emissions. More than half of the respondents believe it’s necessary to be prepared for more frequent high precipitation events like heavy rainstorms, even though many remain uncertain that increased atmospheric moisture due to higher emissions is to blame.

That’s why the U.S. Department of Agriculture is taking steps to bring current research on changing weather trends and adaptive practices to farmers around the country. The USDA’s eight “climate hubs” focus on communicating strategies for reducing risk and reducing the costs related to variable weather by connecting researchers to farmers on the ground. One of these climate hubs is in Ames, Iowa.

Bakken pipeline seeks official approval

The Texas-based company seeking to build an oil pipeline spanning the state of Iowa has applied for approval from the Iowa Utilities Board, according to the Des Moines Register.

Dakota Access, LLC, a division of Texas company Energy Transfer Partners, is seeking permission to build an underground pipeline that would run from North Dakota’s Bakken oil fields to Patoka, Ill., where it would then be connected to distribution systems across the country. The application, filed Tuesday, has set the stage for an ongoing battle between oil companies and Iowa farmers and environmental experts.

Among the concerns over the project is the potential for disastrous spills, like one that leaked 50,000 gallons of crude oil into the Yellowstone River in Montana. Cities like Glendive, Mo., for which the Yellowstone is the primary water supply, have had to have fresh water hauled in on semi trailers since the accident.

In informational meetings held over the month of December, Iowa farmers spoke out against the pipeline, concerned that the project could not only cut yields but also interfere with drainage systems, as Iowans scramble to tackle the state’s growing agricultural runoff problem.

Not least among these concerns is the pipeline’s significance as a fossil fuel system at a time when Iowa is trying to transition to clean energy. The effects of climate change due to the burning of fossil fuels is expected to more heavily impact Iowa’s agriculture industry over the next few decades.

Oil companies working in the Brakken oil fields are trying to find solutions to the railroad congestion problems caused by the oil surge, leading to a backlog in exports like grains, which share the rails with oil.
