While wildfires have been an occasional phenomenoa, all around the world, California wildfires have become much more prominent and economically destructive, in recent decades.[1][2]
Frequency[edit | edit source]
Of the twenty largest wildfires in California, since accurate records have been kept, only the Matilija Fire of 1932 took place during the 20th Century.[3]
Nine of California's twenty largest fires occurred since 2017.[4][3]
Causes[edit | edit source]
Ecologists have pointed out that the frequency of wildfires goes up with the frequency of periods of drought.[1] Wildfires have become more frequent, and more economically destructive in many regions of the world.[5]
Much of the settled portion of California lies between the coast and the first string of mountains, and are regularly swept by hot, dry Katabatic wind -- downslope winds -- known as the Santa Ana winds. Fires driven by hot dry Santa Ana winds have proven impossible to put out.[4][6] According to Ecology historian Mike Davis: “No one will ever be honest about this, but firefighters have never stopped a wildfire powered by Santa Ana winds. All you can hope for is that the wind will change.”

California in the year 2020 experienced a record breaking number of large fires. Here, we place this and other recent years in a historical context by examining records of large fire events in the state back to 1860. Since drought is commonly associated with large fire events, we investigated the relationship of large fire events to droughts over this 160 years period.

Human-induced climatic change may, over a relatively short time period (< 100 years), give rise to climates outside anything experienced in California since the establishment of an industrial civilization currently sustaining a state population that has increased approximately 41,000% since 1850.

Years deep into what the fire historian Stephen Pyne calls the 'Pyrocene,' there are any number of ways to quantify the new fire regime. Of the nine largest fires in modern California history, every single one has been since 2017, as have three of the five deadliest. According to some analysis, 2.6 million homes in the state are at moderate or high risk of wildfire, and across the region, the U.S. Forest Service recently projected perhaps a doubling of area burned by midcentury.

The social, economic, and ecological impacts of wildfire are an increasing concern in many areas of the world. In North America, the U.S. state of California stands out in terms of recent – 2017 and 2018 – high-loss fire events.

'No one will ever be honest about this, but firefighters have never stopped a wildfire powered by Santa Ana winds,' the environmental historian Mike Davis told me earlier this spring, as we toured hills ravaged by past fires and — redeveloped and reinhabited in their wake — haunted now by future ones. 'All you can hope for is that the wind will change.'
