This On The Radio segment discusses how ash left from California’s recent wildfires may threaten area residents. 

Transcript: The wildfires raging throughout Northern California have finally calmed down, but the fight isn’t over.

This is the Iowa Environmental Focus.

Northern Californians have suffered greatly in the wake of the October’s wildfires that left 42 dead and around 100,000 people displaced. Over 8,000 homes and buildings were destroyed.

Residents of a neighborhood in Santa Rosa are already seeing the effects of the ash, as it has started to cover every available surface. A state of emergency for multiple counties throughout California was issued last month by Gov. Jerry Brown.

Toxic ash could contain any number of hazardous materials, including trace amounts of arsenic and lead, according to the California Department of Toxic Substances Control. Many places effected by the ash have already issued health warnings to residents.

Efforts by the state of California have been made to clean up the toxic material and debris before the rainy season commences and washes toxins into local waterways.

Climate change made California wildfires more severe

A report published on Thursday in the Massachusetts Institute of Technology (MIT) Technology Review stated that human-induced climate change is likely to blame for the nearly two dozen wildfires ripping across northern California.

The wildfires have burned nearly 190,000 acres so far and killed 31 residents. While the source of the initial flames remains unknown, MIT points out that parts of California recently experienced a five-year drought which was “very likely” caused by climate change. The long drought left more than 100 million dead trees in its wake, which added to the amount of fuel available to this week’s wildfires. Couple that with record-setting heat in California this summer, another consequence of a changing climate, and conditions were perfect for fire.

Climate change is impacting the frequency and intensity of wildfires across the country. Since the 1980’s they’ve become more likely and more severe. According to the Union of Concerned Scientists, wildfires now last five times as long, occur nearly four times as often and burn an average of six times more land area than they used to.

Park Williams, a bioclimatologist at Columbia University, recently published a study looking at the impact of human-induced climate change on the size of the area wildfires have burned the western U.S. Referring to climate change, he said, “No matter how hard we try, the fires are going to keep getting bigger, and the reason is really clear.”

Wildfires bring smoke to Iowa

A yellowish haze blanketed most of eastern Iowa this Labor Day weekend thanks to wildfires in the western U.S. and Canada.

Wildfires throughout Montana, Manitoba and Saskatchewan are credited with much of this weekend’s smoke. Just this Sunday, evacuations were ordered for Glacier National Park in Montana and 140 campers were rescued from a smoldering forest on Sunday in Oregon.

As the climate changes, wet areas become wetter and dry areas become drier, allowing for longer wildfire seasons in many parts of the western U.S. According to the Union of Concerned Scientists, compared to the 1980’s, wildfires now last nearly five times as long, occur almost four times as often and burn more than six times the land area on average.

National Weather Service meteorologist Dave Cousins said that this weekend’s haze cut visibility at Davenport Municipal Airport by two and a half miles.

A report out of Dubuque revealed that the Air Quality Index (AQI) in the area is moderate to unhealthy for individuals sensitive to poor area quality.

Wildfires become more common and intense as Earth warms up

A wildfire as large as New York City is currently ripping across eastern Montana, and experts say climate change making fires like these larger and more common.

As climate change takes hold, wet areas are becoming wetter and dry areas are becoming drier. Rising temperatures in spring and summer months mean that soils are remaining dry for longer, which makes drought more likely, thereby lengthening the wildfire season.

According to the Union of Concerned Scientists, wildfires have become more likely and more intense since the 1980’s. They last nearly five times as long, occur almost four times as often and burn more than six times the land area on average.

Moving forward, residents of fire-prone regions can expect the wildfire season to lengthen. In the southwestern U.S., scientists predict wildfire season will increase from  seven months to twelve months.

The economic impacts of wildfires are staggering. Since 2000, the U.S. Forest Service has spent more than $1 billion on fire suppression in one fiscal year on two occasions. During the first decade of the 21st century, wildfires cost an average of $665 million per year in economic damages.

In their full report on this issue, the Union of Concerned Scientists say it’s not too late for humans to slow the course of climate change. They write,

“The global temperature is increasing and the climate is changing due to the greenhouse-gas emissions we have already produced, leading to a likely rise in the incidence of wildfires. But it is not too late. What we do now has the power to influence the frequency and severity of these fires and their effects on us.”

Georgia wildfire inches closer to rural communities

The West Mims Wildfire near the Georgia-Florida state line has been burning for weeks and shows few signs of slowing down.

The wildfire was ignited on April 6th when a lightening strike touched down inside the swampy Okefenokee National Wildlife Refuge. Since then, the fire has torched more than 133,000 acres and counting. Until this weekend, the wildfire did not pose a threat to humans in the area. After the fire crossed manmade fire breaks this weekend, an evacuation notice was sent out to residents of two small rural communities in Charlton county, St. George and Moniac.

By Monday, the fire had already burned about 37 square miles in Charlton county and 210 square miles total. Susan Heisey is supervisory ranger for the Okefenokee refuge. She said, “The accumulated moisture in the vegetation is at record-breaking lows right now. These fuels, they’re getting one little piece of ash and the fire’s just picking up and moving.”

A high pressure system in the southeast United States contributed to temperatures nearing 90 degrees Fahrenheit in the area on Monday, with humidity at just 20 percent. As temperatures remain high for the next few days and dry winds continue to blow across the West Mims fire, spokespeople for fire-fighting effort expect the fire to continue burning wherever fuel is available to it.

So far, there are 624 personnel working to keep the fire under control. A detailed incident report outlines predictions of the fire’s status over the next 72 hours. The report reads, “The drying trend will continue causing more fuels to become available to burn in the swamp. Fire activity will increase in areas that have not seen much heat over past few day. Re-burn potential remains very high.”

Climate change has lengthened the wildfire season in the U.S. by 78 days since the 1970’s. Rising temperatures and more frequent, intense droughts have contributed to more intense wildfires across the country.

Colorado wildfire smoke drifting over Iowa

Smoke from the Colorado wildfires has drifted over Iowa, and while it isn’t expected to generate any health problems in the state, Iowan’s can expect redder skies at dawn and dusk until the plume passes.

“Primarily, you’ll notice it toward the evening hours. The sky will be hazier,” said National Weather Service meteorologist Kevin Skow. “The sunsets and sunrises will be redder than normal.”

Meteorologists say they haven’t observed any dust particles in the smoke that could settle on structures in Iowa, and the Iowa Department of Natural Resources still lists the state’s air quality as “good.”

Iowans help battle Colorado wildfire

As the Colorado wildfire continues, Iowans offer a helping hand.

According to their Twitter account, the Iowa Department of Natural Resources has sent two fire engines and two firefighting crews (eight firefighters in total) to help contain the Colorado wildfires.

There are another 20 Iowa firefighters ready to leave for Colorado if needed.
