Fires and droughts in the western states are getting worse — and they’re combining with industrial sources to threaten air quality and people’s health.
estimated that, by 2025, the oil and gas sector alone will be responsible for 970 ozone-related premature deaths and 1,000 PM-related deaths nationwide — as well as thousands of hospital visits and more than one million cases of exacerbated asthma and acute respiratory symptoms.
But this is getting harder as the climate changes. “Our windows of opportunity to do prescribed fire safely have shrunk considerably,” says Colleen Reid, an environmental health researcher at the University of Colorado at Boulder.Sometimes those windows slam shut abruptly. In April, a prescribed burn in New Mexico grew uncontrollably into a megafire that burnt more than 137,000 hectares.
Concerns over prescribed burns have grown so strong that a sheriff in eastern Oregon arrested a US Forest Service employee this year for starting a fuel-thinning fire that reportedly damaged some private property. Even with these tensions, states are trying to make progress.
Another issue is how states count carbon emissions, says Miller. Wildfire emissions will complicate California’s efforts to achieve its goal of carbon neutrality by 2045. The California Air Resources Board estimates that the 2020 wildfire season generated 112 million tonnes of carbon dioxide emissions.
