The human mind can’t handle this being just a fire.
Almost no city in the country is destroyed more often than Los Angeles. America’s second-biggest city has been flattened, shaken, invaded, subsumed by lava, and calved off into the sea dozens of times on screen over the years; as the filmmaker and critic Thom Andersen has said, “Hollywood destroys Los Angeles because it’s there.”
But, understandably, when this destruction leaps from Netflix to a newscast, it’s an entirely different horror to behold. The L.A. County fires have now collectively burned an area more than twice the size of Manhattan; more than 10,000 businesses and homes that were standing last weekend are now ash. Officially, 10 people have died, but emergency managers have warned the public to brace for more. “It looks like an atomic bomb dropped in these areas. I don’t expect good news, and we’re not looking forward to those numbers,” Los Angeles County Sheriff Robert Luna said in a late Thursday press conference.
The mind gropes for an explanation for this horror — and lands in bizarre places. Much has been made in the past few days of the rampant proliferation of conspiracy theories and rumors about the fires, ranging from the believable to the totally absurd. Alex Jones has claimed the fires are part of a “globalist plot to wage economic warfare and deindustrialize the U.S.” (a theory incoming government official Elon Musk endorsed as “true”). Libs of TikTok and others have said that the Los Angeles Fire Department’s hiring practices emphasizing diversity have left it strapped for personnel to fight the wildfires (Musk endorsed this one, too). President-elect Donald Trump has blamed California Gov. Gavin Newsom for the well-publicized occurrence of dry fire hydrants, citing a “water declaration resolution” that supposedly limited firefighters’ access to water, even though such a thing doesn’t exist. Still others have taken to TikTok to spread claims that the fires were intentionally started to burn rapper and producer Sean “Diddy” Combs’ property and hide criminal evidence that could be used to support sex trafficking and racketeering charges against him (another lie). Mel Gibson even used the disaster as an opportunity to share his thoughts about climate change on The Joe Rogan Podcast (spoiler alert: he doesn’t think it’s real), even as his house in Malibu burned to the ground.
“We need some kind of explanation psychologically, especially if you’re not accustomed to that kind of thing happening,” Margaret Orr Hoeflich, a misinformation scholar, told me of how conspiracy theories spring up during disasters. She added that much of the rhetoric she’s seen — like that some cabal set the fires intentionally — has been used to “explain” other similar disasters, including the wildfire in Lahaina in 2023. (“The Diddy one is really unique,” she allowed.)
It’s convenient to call this the coping mechanism of loons, bad actors, the far right, or people who want to promote a political agenda disingenuously, but left-leaning thinkers aren’t exempt. Posts blaming ChatGPT make important points about AI technologies’ energy and water use, but the fires aren’t “because” of ChatGPT.
I’ve also seen the fires blamed on “forest management,” although the landscape around L.A. isn’t trees; it’s shrubland. “This kind of environment isn’t typically exposed to low intensity, deep, frequent fires creeping through the understory, like many dry forests of the Sierra Nevadas or even Eastern Oregon and Washington,” where the U.S. Forest Service’s history of fire has created the conditions for the high-intensity megafires of today, Max Moritz, a cooperative extension wildfire specialist at U.C. Santa Barbara’s Bren School of Environmental Science and Management, told me earlier this week. The shrublands around L.A., rather, “naturally have long-interval, high-intensity, stand-replacing fires” — that is, fires that level almost all vegetation in an area before new growth begins.
The fires in L.A. are extreme not so much because the landscape hasn’t been managed properly (not to mention that prescribed burns in the steep hillsides and suburbs are challenging and huge liabilities), but rather because we’ve built neighborhoods into a wildland that has burned before and will burn again. But unless your algorithm is tuned to the frequency of climate and weather models, you won’t necessarily find this more complicated narrative on social media.
We should also be precise in how we talk about climate change in relation to the fires. It’s true the fires have an excess of dry vegetative fuels after a wet winter and spring, which germinated lots of new green shoots, followed by a hot, dry summer and delayed start to the rainy season, which burned them to a crisp — classic “see-sawing” between extremes that you can expect to see as the planet warms. But droughts don’t always have a strong climate change signal, and wildfires can be tricky to attribute to global warming definitively. Were the Los Angeles fires exacerbated by our decades of burning fossil fuels? It is pretty safe to say so! But right-wing narratives aren’t the only ones that benefit from an exaggerated posture of certainty.
To state what is hopefully obvious: Being overly confident in attributing a disaster to climate change is not equivalent to denying the reality of climate change, the latter being very much more wrong and destructive than the former. But it’s also true overall that humans, as a species, don’t like ambiguity. Though the careful work of uncovering causes and attributing them can take years, it’s natural to look for simple answers that confirm our worldviews or give us people to blame — especially in the face of a disaster that is so unbelievably awful and doesn’t have a clear end. If there’s a role for the creative mind during all of this, it’s not in jumping to logical extremes; it’s in looking forward, ambitiously and aggressively, to how we can rebuild and live better.
“There’s a lot of finger-pointing going around, and I would just try to emphasize that this is a really complex problem,” Faith Kearns, a water and wildfire researcher at Arizona State University, told me this week. “We have lots of different responsible parties. To me, what has happened requires more of a rethink than a blame game.”

Plus 3 more outstanding questions about this ongoing emergency.
As Los Angeles continued to battle multiple big blazes ripping through some of the most beloved (and expensive) areas of the city on Friday, a question lingered in the background: What caused the fires in the first place?
Though fires are less common in California during this time of the year, they aren’t unheard of. In early December 2017, power lines sparked the Thomas Fire near Ventura, California, which burned through to mid-January. At the time it was the largest fire in the state since at least the 1930s. Now it’s the ninth-largest. Although that fire was in a more rural area, it ignited for some of the same reasons we’re seeing fires this week.
Read on for everything we know so far about how the fires started.
Six major fires started during the Santa Ana wind event this week:
Officials have not made any statements about the cause of any of the fires yet.
On Thursday morning, Edward Nordskog, a retired fire investigator from the Los Angeles Sheriff’s Department, told me it was unlikely they had even begun looking into the root of the biggest and most destructive of the fires in the Pacific Palisades. “They don't start an investigation until it's safe to go into the area where the fire started, and it just hasn't been safe until probably today,” he said.
It can take years to determine the cause of a fire. Investigators did not pinpoint the cause of the Thomas Fire until March 2019, more than two years after it started.
But Nordskog doesn’t think it will take very long this time. It’s easier to narrow down the possibilities for an urban fire because there are typically both witnesses and surveillance footage, he told me. He said the most common causes of wildfires in Los Angeles are power lines and those started by unhoused people. They can also be caused by sparks from vehicles or equipment.
At about 35,000 acres burned total, these fires are unlikely to make the charts for the largest in California history. But because they are burning in urban, densely populated, and expensive areas, they could be some of the most devastating. With an estimated 9,000 structures damaged as of Friday morning, the Eaton and Palisades fires are likely to make the list for most destructive wildfire events in the state.
And they will certainly be at the top for costliest. The Palisades Fire has already been declared a likely contender for the most expensive wildfire in U.S. history. It has destroyed more than 5,000 structures in some of the most expensive zip codes in the country. Between that and the Eaton Fire, Accuweather estimates the damages could reach $57 billion.
While we don’t know the root causes of the ignitions, several factors came together to create perfect fire conditions in Southern California this week.
First, there’s the Santa Ana winds, an annual phenomenon in Southern California, when very dry, high-pressure air gets trapped in the Great Basin and begins escaping westward through mountain passes to lower-pressure areas along the coast. Most of the time, the wind in Los Angeles blows eastward from the ocean, but during a Santa Ana event, it changes direction, picking up speed as it rushes toward the sea.
Jon Keeley, a research scientist with the US Geological Survey and an adjunct professor at the University of California, Los Angeles told me that Santa Ana winds typically blow at maybe 30 to 40 miles per hour, while the winds this week hit upwards of 60 to 70 miles per hour. “More severe than is normal, but not unique,” he said. “We had similar severe winds in 2017 with the Thomas Fire.”
Second, Southern California is currently in the midst of extreme drought. Winter is typically a rainier season, but Los Angeles has seen less than half an inch of rain since July. That means that all the shrubland vegetation in the area is bone-dry. Again, Keeley said, this was not usual, but not unique. Some years are drier than others.
These fires were also not a question of fuel management, Keeley told me. “The fuels are not really the issue in these big fires. It's the extreme winds,” he said. “You can do prescription burning in chaparral and have essentially no impact on Santa Ana wind-driven fires.” As far as he can tell, based on information from CalFire, the Eaton Fire started on an urban street.
While it’s likely that climate change played a role in amplifying the drought, it’s hard to say how big a factor it was. Patrick Brown, a climate scientist at the Breakthrough Institute and adjunct professor at Johns Hopkins University, published a long post on X outlining the factors contributing to the fires, including a chart of historic rainfall during the winter in Los Angeles that shows oscillations between wet and dry years over the past eight decades.
But climate change is expected to make dry years drier and wet years wetter, creating a “hydroclimate whiplash,” as Daniel Swain, a pre-eminent expert on climate change and weather in California puts it. In a thread on Bluesky, Swain wrote that “in 2024, Southern California experienced an exceptional episode of wet-to-dry hydroclimate whiplash.” Last year’s rainy winter fostered abundant plant growth, and the proceeding dryness primed the vegetation for fire.

At least 10 people are known to have died in the Los Angeles fires, and some 10,000 structures are believed to have been destroyed. Five blazes continue to burn. The Palisades fire, the largest in the city’s history at 20,000 acres, remains just 6% contained. The Eaton fire has consumed 13,700 acres and is 0% contained. While lower wind speeds have helped firefighters make some progress over the last 24 hours, the Santa Ana gusts were expected to peak at 75 mph last night. “We are absolutely not out of this extreme weather event,” Los Angeles fire chief Kristin M. Crowley said in a news conference.

President Biden sent more than 30 government helicopters and planes to fight the flames, and said federal funding would cover the costs of the fire response for 180 days. (An early estimate from AccuWeather puts the cost of the disaster at more than $50 billion.) Biden also connected the emergency to climate change. “All has changed in the weather,” he said. “Climate change is real. We’ve got to adjust to it, and we can, it’s within our power to do it. But we’ve got to acknowledge it.”
Some of the world’s leading weather research organizations are releasing data today showing that 2024 was the hottest year on record. The World Meteorological Organization, the European Copernicus Climate Change Service, the UK Met Office, Berkeley Earth, NOAA, NASA, and others “have made a concerted effort to coordinate the release of their data, highlighting the exceptional conditions experienced during 2024,” Copernicus said. The service is one of the first to roll out its findings, showing that the global average temperature last year was 59.18 degrees Fahrenheit, or 15.10 degrees Celsius. This is 1.60 degrees Celsius higher than the pre-industrial average, making last year the first full calendar year during which the 1.5C warming threshold has been breached.

Oceans also were exceptionally warm, with sea surface temperatures reaching new record highs. Atmospheric concentrations of greenhouse gas emissions also increased. “These high global temperatures, coupled with record global atmospheric water vapour levels in 2024, meant unprecedented heatwaves and heavy rainfall events, causing misery for millions of people,” said Samantha Burgess, strategic climate lead with the European Centre for Medium-Range Weather Forecasts.
BlackRock yesterday announced its departure from the UN Net Zero Asset Managers Initiative. The decision is “a remarkable U-turn for a company that was once a poster child of the environmental, social, and governance investing movement,” saidThe Wall Street Journal. Asset managers participating in the initiative pledge to support the goal of net-zero greenhouse gas emissions by 2050. BlackRock’s departure is significant because it’s the largest asset manager in the world, but so far it “has not prompted others to follow,” Reutersreported. More than 325 signatories managing more than $57 trillion are still signed on to NZAMI. BlackRock is currently being sued by 11 Republican-led states over ESG investing practices.
“Climate change poses one of the greatest risks to our global economy and the long-term investments BlackRock’s clients rely on,” said Ben Cushing, campaign director for the Sierra Club’s Fossil-Free Finance campaign. “Membership in voluntary alliances sets an important baseline, but to truly fulfill its fiduciary duty to long-term investors, BlackRock must support real-world decarbonization through stronger shareholder voting and by directing capital toward industries that mitigate systemic climate risks. If BlackRock won’t do that, its clients should find a different asset manager that will.”
Coming later today (probably): President Biden will release short-term guidance on clean fuel tax credits, two sources toldReuters. But the final rules will be left to the incoming Trump administration, meaning “biofuel companies and their legislative backers will have to wait to see if Trump will back the plan on the highly anticipated guidelines on new clean fuel production tax credits aimed at the airline and biofuel industries.” The tax credits were supposed to come into effect on January 1 to help spur on production of sustainable aviation fuels.
China is reportedly planning to build a massive solar power station in space to harness the sun’s energy and beam it back to Earth. A Chinese scientist told the South China Morning Post that super-heavy rockets will be launched to build the station, which will be “another Three Gorges Dam project above the Earth.” Space-based solar power is a “tantalizing” way to generate clean energy from the sun around the clock, and many countries are investing in R&D on the idea. The European Space Agency estimates sunlight is 10 times more intense at the top of the atmosphere than on Earth’s surface, but “in order to generate optimal, economically-viable levels of solar power, the required structures need to be very large, both on Earth and in space.” NASA noted that researchers would need to figure out how to build these large structures in orbit, then make sure they can operate autonomously. Plus, manufacturing costs would be extremely high. “Moving all that mass into orbit would require many sustained missions to carry infrastructure into space,” NASA said. China’s electricity demand rose by 6.4% in 2023, and the country is leading in clean energy investments. According to the International Energy Agency, China commissioned as much solar power in 2023 as the entire world did in 2022.
“While it would take an act of God far stronger than a fire to keep people from building homes on the slopes of the Santa Monica Mountains or off the Pacific Coast, the city that rebuilds may be smaller, more heavily fortified, and more expensive than the one that existed at the end of last year. And that’s just before the next big fire.” –Heatmap’s Matthew Zeitlin on the economic devastation of the LA fires
Recovering from the Los Angeles wildfires will be expensive. Really expensive. Insurance analysts and banks have already produced a wide range of estimates of both what insurance companies will pay out and overall economic loss. AccuWeatherhas put out an eye-catching preliminary figure of $52 billion to $57 billion for economic losses, with the service’s chief meteorologist saying that the fires have the potential to “become the worst wildfire in modern California history based on the number of structures burned and economic loss.” On Thursday, J.P. Morgan doubled its previous estimate for insured losses to $20 billion, with an economic loss figure of $50 billion — about the gross domestic product of the country of Jordan.
The startlingly high loss figures from a fire that has only lasted a few days and is (relatively) limited in scope show just how distinctly devastating an urban fire can be. Enormous wildfires thatcover millions of acres like the 2023 Canadian wildfires can spew ash and particulate matter all over the globe and burn for months, darkening skies and clogging airways in other countries. And smaller — and far deadlier fires — than those still do not produce the same financial roll.
It’s in coastal Southern California where you find large population centers areas known by all to be at extreme risk of fire. And so a fire there can destroy a whole neighborhood in a few hours and put the state’s insurance system into jeopardy.
One reason why the projected economic impacts of the fires are so high is that the structures that have burned and the land those structures sit on are very valuable. Pacific Palisades, Malibu, and Santa Monica contain some of the most sought-after real estate on planet earth, with typical home prices over $2 million. Pacific Palisades itself has median home values of around $3 million, according to JPMorgan Chase.
The AccuWeather estimates put the economic damage for the Los Angeles fires at several times previous large, urban fires — the Maui wildfire in 2023 was estimated to cause around $14 billion of economic loss, for example — while the figure would be about a third or a quarter of a large hurricane, which tend to strike areas with millions of people in them across several states.
“The fires have not been contained thus far and continue to spread, implying that estimates of potential economic and insured losses are likely to increase,” the JPMorgan analysts wrote Thursday.
That level of losses would make the fires costlier in economic terms than the 2018 Butte County Camp Fire, whose insured losses of $10 billion made it California’s costliest at the time. That fire was far larger than the Los Angeles fires, spreading over 150,000 acres compared to just over 17,000 acres for the Palisades Fire and over 10,000 acres for the Eaton Fire. It also led to more than 80 deaths in the town of Paradise.
So far, around 2,000 homes have been destroyed,according to the Los Angeles Times,a fraction of the more than 19,000 structures affected by the Camp Fire. The difference in estimated losses comes from the fact that homes in Pacific Palisades weigh in at more than six times those in rural Butte, according to JPMorgan.
While insured losses get the lion’s share of attention when it comes to the cost impacts of a natural disaster, the potential damages go far beyond the balance sheet of insurers.
For one, it’s likely that many affected homeowners did not even carry insurance, either because their insurers failed to renew their existing policies or the homeowners simply chose to go without due to the high cost of what insurance they could find. “A larger than usual portion of the losses caused by the wildfires will be uninsured,” according to Morningstar DBRS, which estimated total insured losses at more than $8 billion. Many homeowners carry insurance from California’s backup FAIR Plan, which may itself come under financial pressure, potentially leading to assessments from the state’s policyholders to bolster its ability to pay claims.
AccuWeather arrived at its economic impact figure by looking not just at losses from property damage but also wages that go unearned due to economic activity slowing down or halting in affected areas, infrastructure that needs to be repaired, supply chain issues, and transportation snarls. Even when homes and businesses aren’t destroyed, people may be unable to work due to evacuations; businesses may close due to the dispersal of their customers or inability of their suppliers to make deliveries. Smoke inhalation can lead to short-, medium-, and long-term health impacts that take a dent out of overall economic activity.
The high level of insured losses, meanwhile, could mean that insurers’ will see less surplus and could have to pay more for reinsurance, Nancy Watkins, an actuary and wildfire expert at Milliman, told me in an email. This may mean that they would have to shed yet more policies “in order to avoid deterioration in their financial strength ratings,” just as California has been trying to lure insurers back with reforms to its dysfunctional insurance market.
The economic costs of the fire will likely be felt for years if not decades. While it would take an act of God far stronger than a fire to keep people from building homes on the slopes of the Santa Monica Mountains or off the Pacific Coast, the city that rebuilds may be smaller, more heavily fortified, and more expensive than the one that existed at the end of last year. And that’s just before the next big fire.
