Fire season in California is changing dramatically. It’s starting earlier and lasting longer, and this trend affects everyone in the state.
Recent research shows that in some areas, like the Sierra Nevada, fire season now kicks off about 24 days sooner than it did in the early 1990s. In the Northern Basin and Range, it’s even more striking—31 days earlier. The Cascade Range, extending into Oregon, sees fire season starting a staggering 46 days earlier.
Amanda Fencl, a climate expert from the Union of Concerned Scientists, emphasizes the importance of this study. “We’ve felt the shift, but now we have data to back it up,” she said. This research links these changes directly to climate factors, especially an earlier snowmelt and drier conditions, which increase the risk of fires.
Interestingly, while California’s population has grown by about 27% since the ’90s, the number of human-caused fires has actually decreased. This suggests that the earlier seasons are not due to more people setting fires, but climate change is the real culprit.
Gavin D. Madakumbura, a researcher at UCLA, points out that “the main driver is the climate and meteorological conditions.” This makes fire a constant threat in certain Northern California regions. James Thorne, a landscape ecologist from UC Davis, supports this perspective, saying wildfire conditions can feel year-round now.
As of mid-July this year, over 220,000 acres have already burned—nearly 100,000 more than average for this time of year over the past five years. This figure excludes some of the largest ongoing fires, including the Gifford Fire, which has burned thousands of acres and is still not fully contained.
The economic impact of wildfires is staggering. In 2018, the Camp Fire caused about $148.5 billion in damages, making it one of the deadliest and costliest fires in California’s history. More recently, studies have estimated that the Palisades and Eaton fires alone may have resulted in up to $164 billion in losses.
These patterns show how climate change is reshaping the landscape and safety of California. Awareness and understanding of this shift are essential for both residents and policymakers.
