Climate change set the table for Los Angeles wildfires

Taken together, the results all indicate climate change plays a major role and the researchers are confident in the findings that warming increases the chances of such fires.

Many other regions at risk

The researchers were also able to show that the fires’ impacts disproportionately affected elderly people and people with disabilities, such as those with limited mobility, as well as population groups that received late warnings. Some of those effects, they noted, will exacerbate historical economic disparities in ways that could persist long into the future.

“The neighborhood of Altadena with a large Black population was in the path of the fires, which destroyed the major source of generational wealth for many residents who had previously faced discriminatory redlining practices,” the scientists wrote in the report.

The fires exposed critical weaknesses in water infrastructure, which is “designed for routine fires rather than the extreme demands of large-scale fires, and shows the need for investments in resilient water systems and other stronger climate adaptation and emergency preparedness measures to address more frequent future wildfires.”

“This was a perfect storm of climate-enabled and weather-driven fires impacting the built environment,” said co-author John Abatzoglou, a professor of climatology at the University of California, Merced.

There are similar fire-prone communities in other regions, he added, including Boulder County, Colorado, where the 2021 Marshall fire destroyed more than 1,000 homes. Similar disasters have played out recently around the world, including the 2023 Lahaina fire on Maui’s northwest coast, and July 2024 fires in Viña del Mar, Chile.

Williams said the recent fires around Los Angeles don’t even come close to ranking in the top 10 for size.

There are many neighborhoods in Southern California nestled into the heavily vegetated mountainsides from Santa Barbara County through Ventura County, LA County, Orange County and San Diego County that could feasibly be next, he said.

“I’d say that a large number of neighborhoods are at similar risk to the small number of neighborhoods that we saw exposed to the fires this year,” Williams said.
