Dr. Mark Finney: Changing How We Fight (and live with) Fire
Dr. Mark Finney is a Senior Scientist and Research Forester with the U.S. Forest Service at the Missoula Fire Sciences Laboratory. With a Ph.D. in wildland fire science from UC Berkeley, Finney has spent decades exploring fire as both an ecological force and a physical process. His work has laid the foundation for many of the wildfire behavior models used today across the country.
Finney is a strong advocate for rethinking traditional fire suppression strategies. He emphasizes the need to let “good fire” play its role in the landscape, using tools like prescribed burns and targeted fuel treatments to prevent more extreme fires down the line. His research has revealed that long-held beliefs about how fires spread, such as the role of radiant heat, are often incorrect.
A New Kind of Urban Firestorm
Everything around Walker Savage was smoke. Smoke and embers and broken tree limbs and the relentless roar of the wind. Wearing a respirator and goggles from his woodworking studio, he sprayed his garden hose into the gale, hoping to wet the walls and porch of his 99-year-old adobe house enough to keep them from igniting.
But then he saw the flames come surging down the mountain above his home in east Altadena, California: “It was like an avalanche,” Savage said. “But not of snow — it was of fire.”
More than a week later, Savage is still trying to wrap his mind around the Eaton Fire, which killed at least 16 people, destroyed an estimated 7,000 structures and is still only 45 percent contained. The flames moved faster than firefighters could fight them, reaching deep into the suburb to scorch houses well outside the state-designated risk zone.
Inside the L.A. Firestorm
The 2025 LA Wildfires were among the most destructive and costly in U.S. history, driven by a combination of shifting climate patterns and growing development in fire-prone areas. As these types of fires become more common, it raises important questions about how we prepare for and respond to future risks. In this PBS video, experts explore the factors behind the firestorm and what can be done to reduce the impact of similar events going forward.
