Wildfire smoke warnings don’t come soon enough

Environmental and public health agencies often don't warn people about smoke-choked air until it's already swept in, researchers report.

Environmental and public health agencies often don’t warn people about smoke-choked air until it’s already swept in, a new study suggests.

The study in the journal BMC Public Health provides recommendations for how public institutions can more effectively communicate wildfire smoke and its risks to provide people ample time to prepare.

Looking at the Pacific Northwest in particular, researchers from the School of Journalism and Communication at the University of Oregon examined the frequency and content of federal, state, and local agencies’ health communications on X, formerly known as Twitter.

In an analysis led by Catherine Slavik, a postdoctoral researcher in the school’s Center for Science Communication Research, she found that public health messages were primarily reactive: More than half of wildfire-related tweets authored by 32 institutional accounts in 2022 were posted during peak smoke levels, when the risk of exposure was highest.

“On the one side, these institutions are doing a great job of highlighting the risks when the risks are present,” Slavik says. “But going forward, hopefully more of these conversations on smoke will be had before it’s potentially already in the air and too late to prepare.”

Slavik and her colleague Daniel Chapman, a postdoctoral researcher in the Center for Science Communication Research and collaborator with the UO’s Center for Wildfire Smoke Research and Practice, also found that most tweets discussed the hazards but not the actions to mitigate them. Only one in seven of the total 1,287 analyzed tweets instructed and encouraged preparatory actions, such as wearing respirators, staying indoors, and using at-home air purifiers.

“We want to see more emphasis on the actions people can take to help deal with wildfire smoke,” Chapman says. “It’s good to be aware, but in the absence of knowing what to do, awareness can only take you so far.”

Moreover, only 213 of the total tweets used air quality index labels to report how clean or polluted the air was. Even fewer—64 tweets—described risks with numeric information, such as the percentage likelihood of a fire spreading or the number of acres burning. Previous research, however, has indicated people prefer and are more motivated by numeric information, Chapman says.

In response, the researchers created a list of best practices for government agencies in Oregon and Washington to consider when communicating wildfires and smoke events:

  • Communicate the severity, risk, likelihood, and mitigation of a hazard.
  • Describe risks with numeric information and air quality index levels.
  • Engage with communities to foster community-building and resilience.
  • Implement proactive communications by discussing wildfire and smoke risks during off-seasons.

Local organizations, like fire departments, are often highly trusted in a community, so messages by regional communicators that incorporate the suggestions may be particularly persuasive, THE researchers say.

“Any institution that has a clear role in its community has a real opportunity to communicate risk and responses effectively,” Chapman says

Journalists also play a key role in telling an accurate and timely story of fire. Hollie Smith, an associate professor of science and environmental communication in the School of Journalism and Communication and a researcher at the Center for Wildfire Smoke Research and Practice, recently coauthored a guide for Oregon reporters covering wildfires . The project, done in partnership with Oregon State University’s Extension Fire Program, provides tips on how to safely approach fire sites and where to obtain credible information.

Smith, associate director of the Center for Science Communication Research, noteS the oftentimes negative language associated with fire in the media. Fire, however, has both ecological and cultural significance. The conversation on what fire means to people needs to be more nuanced, she says.

“It’s helpful to recognize that we will be living with fire,” she says. “So what does that look like today? What did it look like historically? What are the social and economic dimensions of wildfire? These are all important pieces of the conversation.”

The researchers are now looking at how to best present information to specific audiences, such as parents on the West Coast, to motivate proactive protective behaviors. Researchers are also looking into the barriers communication professionals might face when trying to communicate public health risks .

“There are now three seasons in Oregon: rainy, sunny, and smoky,” says Ellen Peters, director of the Center for Science Communication Research. “Smoke is such an important and relatively new risk that we face as Oregonians, and we need to understand what the state and federal agencies are doing to communicate it and how they could do better for our communities.”
