An analysis of the health care records of 1.2 million Southern California residents found that higher long-term smoke exposure was associated with a significant increase in the odds that a person would be diagnosed with dementia. Exposure to non-wildfire PM2.5 also increased a person’s risk of dementia, but to a much lesser degree.
An international team led by researchers at the University of Washington built a framework to help land managers assess the air quality implications of land management scenarios with different levels of prescribed burning.
Taken together, the two papers’ findings suggest that wildfire smoke poses a risk to people of all ages, not just young children and older adults.
Researchers with the University of Washington and the U.S. Forest Service have developed a new tool, REBURN, that can simulate large forest landscapes and wildfire dynamics over decades or centuries under different wildfire management strategies. The model can simulate the consequences of extinguishing all wildfires regardless of size, which was done for much of the 20th century and has contributed to a rise in large and severe wildfires, or of allowing certain fires to return to uninhabited areas to help create a more “patchwork” forest structure that can help lessen fire severity. REBURN can also simulate conditions where more benign forest landscape dynamics have fully recovered in an area.
With wildfire smoke forecast for next week in Seattle and the Occupational Safety and Health Administration in Oregon posting rules for keeping workers safe during increasingly smoky conditions and heat in that state, we caught up with a University of Washington expert on worker safety for advice. Check out Professor Baker’s advice on worker safety in this video. Journalists can download the video here. Marissa Baker, an industrial hygiene program director and assistant professor in the UW Department of…
Firefighters have reported that Western wildfires are starting earlier in the morning and dying down later at night, hampering their ability to recover and regroup before the next day’s flareup. A study by University of Washington and U.S. Forest Service scientists shows why: The drying power of nighttime air over much of the Western U.S. has increased dramatically in the past 40 years.
Seeing the urgent need for change, a team of scientists from leading research universities, conservation organizations and government laboratories across the West has produced a synthesis of the scientific literature that clearly lays out the established science and strength of evidence on climate change, wildfire and forest management for seasonally dry forests. The goal is to give land managers and others across the West access to a unified resource that summarizes the best-available science so they can make decisions about how to manage their landscapes.
A model of the eastern California forests of the Sierra Nevada looks at the longer-term future of wildfires under future climate change scenarios. Results show an initial roughly decade-long burst of wildfire activity, followed by recurring fires of decreasing area — a pattern that could apply to other hot, dry forests in the West.
The biggest study yet of West Coast wildfire plumes shows how a smoke plume’s chemistry changes over time. Results suggest current models may not accurately predict the air quality downwind of a wildfire.
With most of the Northwest blanketed by wildfire smoke, public officials and health experts suggest staying inside as much as possible to reduce exposure to the significant health risks of wildfire smoke. However, inequity in our communities means not every home provides great protection and many workers in disadvantaged populations can’t afford to stay home, says Anjum Hajat, assistant professor of epidemiology in the UW School of Public Health. Hajat’s expertise covers the impact air pollution — including from wildfires…
With wildfire smoke blanketing most of the western U.S. this week, public health experts suggest staying inside as much as possible to protect yourself from smoky air. If you don’t have air conditioning or an air purifier in your home, it’s possible to make your own inexpensive purifier. Here’s how.
Agencies that are well practiced in putting out wildfires are now learning a new skill: how to set the spark and fan the flames. That’s the case for the state Department of Natural Resources, which is starting to use prescribed burning as part of its strategy for fighting wildfires.
The University of Washington has a long history of leading research into the impacts of wildfires from an ecological and health perspective. We worked with two experts to answer some of the most frequently asked questions about wildfires in the Pacific Northwest, including the ways that the pandemic is increasing our community’s vulnerability to extreme wildfire events in the region.
A University of Washington study, published this winter in Fire Ecology, takes a big-picture look at what climate change could mean for wildfires in the Northwest, considering Washington, Oregon, Idaho and western Montana.
In the first major study following the devastating Carlton Complex fire in north central Washington, researchers from the University of Washington and U.S. Forest Service found that previous tree thinning and prescribed burns helped forests survive the fire.
Researchers from the University of Washington and Michigan Technological University have created the first comprehensive database of all the wildfire fuels that have been measured across North America. Ultimately, it can help scientists make more informed decisions about fire and smoke situations.
More than 99 percent of wildfires in the last 40 years have been east of the Cascade Crest. But evidence that suggests Western Washington also has a history of large wildfires, each burning hundreds of thousands of acres. We might not be familiar with them, because most happened centuries ago.
Massive wildfires, which may be getting more intense due to climate change and a long history of fire-suppression policies, have strikingly unequal effects on minority communities, a new study shows.
Forest biologist and University of Washington professor David Peterson explains which natural materials burn hotter and faster during a wildfire, what homeowners can do to protect their properties and how climate change is impacting the fire season.
A new study finds that morel mushrooms cluster in groups across burned areas in the forest after a wildfire. It’s one of the only scientific studies to actually quantify morels’ abundance after a fire.
In a commentary published Sept. 17 in Science, a team of scientists, including University of Washington researchers Jerry Franklin and James Agee, describe unique opportunities and provide suggestions to reform forest fire management to reduce the impacts of inevitable wildfires in future years.
A new comprehensive report co-authored by the UW’s Climate Impacts Group looks at what climate change will mean for Washington, Oregon and Idaho.
