Three important things, plus one very unimportant thing
Hello from Dubai, where the United Nations’ annual climate conference — that is, COP28 — officially began today.
This was an enormous day for climate and environmental news around the world. Not only did COP28 begin with a surprising (and important) accomplishment, but the Environmental Protection Agency proposed cracking down on lead pipes, one of the biggest remaining sources of water pollution in the United States. Tesla is also set to release — and announce a price for — its gargantuan Cybertruck today, one of the most contentious electric vehicles launches in history.
So let’s get down to it.
1. COP28 officially began. This afternoon, the 28th Conference of the Parties to the United Nations Framework Convention on Climate Change — or COP28 — officially began. It will run here at Expo City at the southern end of Dubai until December 12.
It was not, technically, the only climate conference that started in Dubai today: Technically, three conferences kicked off. That is because since the world adopted the Framework Convention on Climate Change in 1992 — which is the big, arching UN treaty to do something about climate change— countries have stacked other agreements on top of it. So today was also the beginning of CMP18 (the 18th Meeting of the Parties to the Kyoto Protocol) and CMA5 (the fifth Meeting of the Parties to the Paris Agreement).
2. The conference launched the loss and damage fund. This was a welcome surprise. For years, countries have debated over “loss and damage” — essentially, what richer countries that are responsible for most global warming so far owe to poorer countries that are dealing with its consequences. Last year at the COP in Sharm el-Sheikh, Egypt, countries agreed to establish a loss and damage fund for the first time. They’ve been hammering out the details over the past year — at the insistence of the U.S. and Europe, the fund will be hosted first by the World Bank — and today the fund was officially launched, or in UN parlance, operationalized.
Germany, Japan, the United States, the United Kingdom, and the United Arab Emirates all gave money to the fund. The U.S. donated the second smallest amount, after Japan.
3. The World Meteorological Organization confirmed that 2023 will be the hottest year in human history. Since temperatures in July, August, and September destroyed all-time records, this sad milestone has been more or less expected. But today the World Meteorological Organization, a UN-associated weather body, confirmed that 2023 will be the hottest year ever measured.
Tomorrow, a subsection of COP — the World Climate Action Summit (!) — will begin. This is the part of COP where various world leaders come and speak to the negotiators.
This year sports a perhaps underwhelming set of world leaders. Neither President Joe Biden nor President Xi Jinping will be attending. The highest profile elected leaders will probably be President Luiz Inácio Lula da Silva of Brazil and Prime Minister Rishi Sunak of the United Kingdom. King Charles III is also coming.
Following this event, but also overlapping with it, will be a period with lots of big announcements. Investors will announce new projects and investments. Companies will announce new voluntary climate-action coalitions. Countries and cities will announce new coalitions of voluntary action. It will be fairly hard to tell which of these actually matter in the moment, but some of them probably will.
Then there will probably be a news lull for a few days. Finally, at the end of the conference, negotiators will hash out the details of this year’s joint statement.
Even though COP officially starts today, it was largely uneventful here in Dubai. No world leaders spoke; the only big news was the loss and damage fund. Many news articles heralded that COP has begun in Dubai!, without saying what, exactly, that means or how people are spending their time.
Let me decipher it for you. While COP is an international media spectacle, it’s also an enormous in-person conference — and it is subject to some irreducible geometric challenges. This year, those challenges exist on a new scale: With more than 80,000 people attending the Dubai proceedings, this is by far the largest COP ever. (For comparison, about 50,000 people attended the Paris COP in 2015, when the Paris Agreement was adopted.)
Here is what I mean: Today, everyone had to pick up their conference badges and lanyards. That is what happened at COP today. A small suburb’s worth of people — including me—waited in a line to go through security and show a chipper UN employee our registration papers and get our photo taken. The line was about 1.2 kilometers long (literally— I corroborated that with my Apple Health data) but it was run efficiently and cheerfully.
According to a forensic reconstruction of my activities, compiled chiefly from an Uber receipt and the timestamp on some iPhone photos, I arrived at the conference center at 12:25pm and had a name badge almost exactly two hours later. I began keeping a journal when I realized that I was unlikely to get to the front of the line any time soon.
12:25 p.m. I arrive at Expo 2020, the nearest dropoff to the conference center. A man with a UN badge tells me to join a line without providing any details. I decide to follow the late Soviet rule that if you see a long line, you should just get in it.
12:35 p.m. A quasi-status system immediately makes itself clear. Some people have green lanyards, which entitle them to enter the Green Zone, the “trade show” part of the COP, which is governed by the U.A.E. Others have blue lanyards, which let them the Blue Zone, the official UN part of the conference.
1:14 p.m. We are handed aluminum Aquafina cans, a thoughtful gesture. Many of the people near me in line seem to be in their 50s and 60s, and the subtropical sun is hot and unrelenting. They must be starting to lose it out here.
1:18 p.m. Studying the can, I notice it is labeled “Still Drinking Water.” I find the “still” to be ontologically reassuring. It is good to know that this is still drinking water. Thank goodness I am not losing it like all these middle-aged people around me.
1:35 p.m. A 30-something man in line is wearing a t-shirt with the words “Dinosaur Facts” on it. Highlight of my COP so far.
1:46 p.m. I dimly realize that Sydney, Australia, (where it is 8:46pm) is closer to Dubai time than New York is.
1:51p.m. It strikes me that COP and Disney World are plagued by the same problem: very long lines. But if this were Disney World, we would have encountered several entertaining animatronics by now.
2:19 p.m. I finally reach through security and waiting in the final room: to receive my pass. As soon as I get through, I realize I have been silently standing in line next to a very famous environmental justice academic for an hour. With that opportunity already squandered, my COP begins.

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.
Suburban streets, exploding pipes, and those Santa Ana winds, for starters.
A fire needs three things to burn: heat, fuel, and oxygen. The first is important: At some point this week, for a reason we have yet to discover and may never will, a piece of flammable material in Los Angeles County got hot enough to ignite. The last is essential: The resulting fires, which have now burned nearly 29,000 acres, are fanned by exceptionally powerful and dry Santa Ana winds.
But in the critical days ahead, it is that central ingredient that will preoccupy fire managers, emergency responders, and the public, who are watching their homes — wood-framed containers full of memories, primary documents, material wealth, sentimental heirlooms — transformed into raw fuel. “Grass is one fuel model; timber is another fuel model; brushes are another — there are dozens of fuel models,” Bobbie Scopa, a veteran firefighter and author of the memoir Both Sides of the Fire Line, told me. “But when a fire goes from the wildland into the urban interface, you’re now burning houses.”
This jump from chaparral shrubland into neighborhoods has frustrated firefighters’ efforts to gain an upper hand over the L.A. County fires. In the remote wilderness, firefighters can cut fire lines with axes, pulaskis, and shovels to contain the blaze. (A fire’s “containment” describes how much firefighters have encircled; 25% containment means a quarter of the fire perimeter is prevented from moving forward by manmade or natural fire breaks.)
Once a fire moves into an urban community and starts spreading house to house, however, as has already happened in Santa Monica, Pasadena, and other suburbs of Los Angeles, those strategies go out the window. A fire break starves a fire by introducing a gap in its fuel; it can be a cleared strip of vegetation, a river, or even a freeway. But you can’t just hack a fire break through a neighborhood. “Now you’re having to use big fire engines and spray lots of water,” Scopa said, compared to the wildlands where “we do a lot of firefighting without water.”
Water has already proven to be a significant issue in Los Angeles, where many hydrants near Palisades, the biggest of the five fires, had already gone dry by 3:00 a.m. Wednesday. “We’re fighting a wildfire with urban water systems, and that is really challenging,” Los Angeles Department of Water and Power CEO Janisse Quiñones explained in a news conference later that same day.
LADWP said it had filled its 114 water storage tanks before the fires started, but the city’s water supply was never intended to stop a 17,000-acre fire. The hydrants are “meant to put out a two-house fire, a one-house fire, or something like that,” Faith Kearns, a water and wildfire researcher at Arizona State University, told me. Additionally, homeowners sometimes leave their sprinklers on in the hopes that it will help protect their house, or try to fight fires with their own hoses. At a certain point, the system — just like the city personnel — becomes overwhelmed by the sheer magnitude of the unfolding disaster.
Making matters worse is the wind, which restricted some of the aerial support firefighters typically employ. As gusts slowed on Thursday, retardant and water drops were able to resume, helping firefighters in their efforts. (The Eaton Fire, while still technically 0% contained because there are no established fire lines, has “significantly stopped” growing, The New York Times reports). Still, firefighters don’t typically “paint” neighborhoods; the drops, which don’t put out fires entirely so much as suppress them enough that firefighters can fight them at close range, are a liability. Kearns, however, told me that “the winds were so high, they weren’t able to do the water drops that they normally do and that are an enormous part of all fire operations,” and that “certainly compounded the problems of the fire hydrants running dry.”
Firefighters’ priority isn’t saving structures, though. “Firefighters save lives first before they have to deal with fire,” Alexander Maranghides, a fire protection engineer at the National Institute of Standards and Technology and the author of an ongoing case study of the 2018 Camp fire in Paradise, California, told me. That can be an enormous and time-consuming task in a dense area like suburban Los Angeles, and counterintuitively lead to more areas burning down. Speaking specifically from his conclusions about the Camp fire, which was similarly a wildland-urban interface, or WUI fire, Maranghides added, “It is very, very challenging because as things deteriorate — you’re talking about downed power lines, smoke obstructing visibility, and you end up with burn-overs,” when a fire moves so quickly that it overtakes people or fire crews. “And now you have to go and rescue those civilians who are caught in those burn-overs.” Sometimes, that requires firefighters to do triage — and let blocks burn to save lives.
Perhaps most ominously, the problems don’t end once the fire is out. When a house burns down, it is often the case that its water pipes burst. (This also adds to the water shortage woes during the event.) But when firefighters are simultaneously pumping water out of other parts of the system, air can be sucked down into those open water pipes. And not just any air. “We’re not talking about forest smoke, which is bad; we’re talking about WUI smoke, which is bad plus,” Maranghides said, again referring to his research in Paradise. “It’s not just wood burning; it’s wood, plastics, heavy metals, computers, cars, batteries, everything. You don’t want to be breathing it, and you don’t want it going into your water system.”
Water infrastructure can be damaged in other ways, as well. Because fires are burning “so much hotter now,” Kearns told me, contamination can occur due to melting PVC piping, which releases benzene, a carcinogen. Watersheds and reservoirs are also in danger of extended contamination, particularly once rains finally do come and wash soot, silt, debris, and potentially toxic flame retardant into nearby streams.
But that’s a problem for the future. In the meantime, Los Angeles — and lots of it — continues to burn.
“I don’t care how many resources you have; when the fires are burning like they do when we have Santa Anas, there’s so little you can do,” Scopa said. “All you can do is try to protect the people and get the people out, and try to keep your firefighters safe.”
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 Thursday, 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.
Five 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 27,000 acres burned, 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 2,000 structures damaged so far, 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 1,000 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 very wet and very dry years over the past eight decades. But climate change is expected to make dry years drier in Los Angeles. “The LA area is about 3°C warmer than it would be in preindustrial conditions, which (all else being equal) works to dry fuels and makes fires more intense,” Brown wrote.
