Distant wildfire smoke may raise ozone levels

Across the U.S., ozone levels were higher on smoky days than on smoke-free days

Staff Report

Wildfire smoke on its own can trigger health warnings for direct exposure, and new research from Colorado State University suggests that there may be a more widespread impact after they linked smoke with elevated levels of ozone.

In globally warming world, where the number and size of wildfires keeps growing, the findings have significant implications for public health. Continue reading

Study shows nuances in Coloradans beliefs about wildfires and climate change

Focusing on local threats, not climate change, may be the best way to spur wildfire mitigation actions

Wildfires are getting bigger in Colorado.

Staff Report

Whether or not people are convinced that human activities are changing the climate doesn’t play a big role in their decisions about trying to reduce wildfire risks around their property, Colorado-based researchers wrote in a new paper that focused on the Colorado Front Range.

The researchers tried to take a close look at social factors that might motivate people to try and lessen wildfire threats. They found that a “belief” in human-caused climate change is not as significant as previously thought. Continue reading

Warmer climate means more fires — any questions?

Study ties ancient wildfire surge in the Rockies to warmer climate phase

Staff Report

Offering yet more evidence that the West’s recent spate of megafires is linked with a warming climate, University of Wyoming researchers showed that a warm spell about 1,000 years ago also spurred more blazes. The study suggests that large fires will continue to increase as a result of a warming climate.

“What our research shows is that even modest regional warming trends, like we are currently experiencing, can cause exceptionally large areas in the Rockies to be burned by wildfires,” says John Calder, a Ph.D. candidate in UW’s Program in Ecology and the Department of Geology and Geophysics.

Forest Service maps development boom in fire-prone exurbs

Budgets aren’t keeping up with wildfire risks

Red zone development boom eats up firefighting budgets.

Staff Report

Sprawling exurban development across the U.S. has put more homes than ever at risk of catastrophic wildfires, according to a new U.S. Forest Service report that maps recent expansion of the so-called wildland-urban interface.

The incredible spurt in home building in that fire-prone zone has  direct implications for the cost of wildfire fighting. Increasing densities of people and infrastructure in the WUI makes wildfire management more complex and requires more firefighting assets to ensure an appropriate, safe and effective response, Forest Service officials said as they released new report.

Drying grasses and shrubs up fire danger in parts of Colorado

Staff Report

FRISCO — Summer may be winding down, but the wildfire season is not over yet. In the past ten days, fire managers and park rangers at Rocky Mountain National Park have responded to four illegal, escaped campfires.

All four were quickly extinguished, each burning less than 0.25 acres, but park managers say they all had the potential to spread quickly and threaten lives and property. Continue reading

U.S. wildfires surge to 10-year high

Feds spending $150 million per day and seek firefighting help from Canada, Australia and New Zealand

Staff Report

FRISCO — This year’s wildfire activity in the U.S. has surged to the highest level in 10 years, with the National Interagency Fire Center reporting that about 7.2 million acres have burned so far, and officials said they expect the wildfire season to intensify in the coming weeks.

The drought-stricken far West is hardest hit, with 16 large fires currently burning in Washington, 14 in California and 12 in Oregon. Forest Service Chief Tom Tidwell said federal agencies are currently spending about $150 million per day on fighting fires across the West. Continue reading

Climate change contributes to longer fire seasons worldwide

New study tracks regional nuances, global trends

Staff Report

FRISCO — U.S. Forest Service scientists and other researchers say there has been a significant increase in the length of wildfire seasons on nearly every continent, with the exception of Australia. Fire weather seasons around the globe have increased by nearly 20 percent and the global burnable area doubled over the past 35 years.

Most vegetation types, except boreal forests, showed significant increases in the fire weather season length, the new study found. Some areas, such as the Western and Southeastern United States, Alaska, tropical and sub-tropical South America and Eastern Africa and large parts of Eurasia show a steady lengthening of the fire season from 1979-2013.
