The Brief

Last year began with the costliest wildfires in American history, as a series of blazes tore across Los Angeles for nearly all of January.

A parade of other catastrophes followed: severe storms across the southern and northeastern United States, tornadoes in the central states, drought and heat waves through the western expanse of the country.

All told, the U.S. notched 23 billion-dollar weather and climate disasters in 2025, which claimed 276 lives and caused $115 billion in damages, according to a new analysis from the research group Climate Central. Only 2023 and 2024 recorded more of these events, and 2025 was the 15th consecutive year with an above-average number. (Since 1980, the annual average has been nine events costing $67.6 billion. In that time, the country tallied 426 total billion-dollar disasters, costing more than $3.1 trillion.) Last year was the ninth most expensive on record for billion-dollar disasters.

The clear signal here is climate change: It’s worsening wildfires, causing heavier rainfall and flooding, and supercharging hurricanes. In the 1980s, billion-dollar disasters happened on average every 82 days, according to the analysis, but over the last decade that window has tightened to just 16 days. In 2025, Americans endured one of these events every 10 days on average — an almost nonstop cavalcade of suffering.

Last May, the Trump administration announced that the National Oceanic and Atmospheric Administration would no longer update the federal government’s own billion-dollar disaster database, to the alarm of experts who call it an essential tool for determining risk and adapting to climate change.

In October, Climate Central revived that database, hence its release of these figures for 2025. “The continuation of this dataset, like other datasets, is important because it helps demonstrate the economic impact of extreme weather and climate events,” said Adam Smith, senior climate impacts scientist with the organization, who’s leading the program and was formerly the lead scientist for NOAA’s version. That, in turn, can give policymakers and the general public more information for “a more enhanced decision-making process, as we try to learn from these events and rebuild after these extremes that we know will continue into the future.”

At $61.2 billion in damages, the Los Angeles fires accounted for more than half of the losses from the 23 total events in 2025, according to the analysis. That outbreak brought a public health crisis that’s harder to calculate: Hundreds of people likely died from inhaling smoke, even if they were many miles away from the flames. Wildfire smoke already exacerbates conditions like heart disease and cardiovascular disease, but this smoke was especially toxic because the fires were chewing through houses and cars, melting plastic and metal.

For the folks who survived inhaling the smoke but nonetheless experienced complications, medical costs add yet more to that $61.2 billion that Climate Central reported. Add still more when you factor in the trauma of surviving such a disaster, and the associated mental health costs.

“Even though we have a very robust, comprehensive estimate based on the data that’s available, it’s still conservative with respect to what is truly lost, but cannot be completely measured,” Smith said.

Elsewhere across the U.S., communities struggled with unruly weather: hail events in Texas and Colorado, and severe storms all across the South and Northeast. (Of the 23 events, 21 were related to tornadoes, hail or high wind events. When considering only severe storms, 2025 was the second most costly year for billion-dollar disasters, after 2023.) Generally speaking, the warmer the atmosphere, the more moisture it can hold and then dump as rain. In addition, the Gulf of Mexico was extra hot in 2025, which added still more moisture to storms that marched across Southern states. (Scientists are still working out how climate change might be influencing tornadoes, like the six separate billion-dollar outbreaks that struck the U.S. in 2025.)

In addition to climate change making weather and wildfires more catastrophic, human factors are adding to the growing costs of billion-dollar disasters. In the West, for example, communities have been expanding into the “wildland-urban interface,” where structures butt up against forests. So there’s more to burn, while at the same time climate change is amplifying the blazes.

“You’re supercharging some of the ingredients that when they’re aligned in a certain way — with the dryness of the fuels and the near hurricane-force winds, and then, of course, some ignition source — it’s literally impossible to stop,” Smith said.

But if climate change is worsening disasters, why didn’t 2025 see more billion-dollar events than the two years before it? And why was it the ninth most expensive, not the first? That’s largely because for the first time in a decade, no hurricane made landfall in the U.S. last year, thanks to an atmospheric quirk above the Southeastern states that created a sort of force field that bounced storms back out to sea. That was fortunate — both for human lives and economic losses — because hurricanes tend to be the costliest of weather and climate extremes.

“If you talk about major hurricanes making landfall, you can easily approach or exceed $100 billion,” Smith said. “The $115 billion could have been $215 billion.”

Although the U.S. got lucky, the hurricane season was still extreme. Only five Atlantic hurricanes spun up, but four of them — or 80 percent — reached major strength, while in a typical year it’s 40 percent. In addition, 2025 was the second year to have produced three or more Category 5 storms, at least in recorded history.

That’s where climate change comes in: It’s boosting hurricanes by warming up the ocean waters the storms use for fuel. And indeed in 2025 those temperatures reached record highs: Hurricane Melissa, which ravaged the Caribbean, fed on waters made hundreds of times more likely by climate change to fuel hurricanes — which increased wind speeds by 11 mph and extreme rainfall by 16%. All that oceanic fuel helped the storm undergo “extreme rapid intensification,” its maximum sustained wind speeds jumping from 70 mph to 140 mph in 18 hours.

So just because no hurricanes made landfall in the U.S. last year doesn’t mean that the storms won’t get more powerful from here.

To prepare, Smith said that Climate Central will be improving the billion-dollar disaster database, for example reexamining historic data to dig more deeply into individual events like wildfires.

“By this time next year,” Smith said, “if we’re having a conversation, I think that it’ll be even a much more useful and helpful data resource.”

A new analysis of alerts sent during the Eaton Fire found “no failure” by emergency officials to issue timely evacuation orders to areas west of Lake Avenue in Altadena.

The timing of alerts to neighborhoods west of Lake, where all but one of 19 deaths in that fire occurred, has been under scrutiny since the January 2025 fire.

The independent report by Citygate Associates was commissioned by the L.A. County Fire Department at the start of this year and was released Monday.

Its conclusions are similar to those of after-action reports from other firms — that officials did the best they could amid unprecedented fire conditions and strained resources.

“While the report provides an honest account of our operations, we recognize that no investigation can truly capture the horror and tragedy residents endured,” said L.A. County Fire Chief Anthony Marrone in a prepared statement. “My focus is to ensure that the lessons learned from the Eaton and Palisades fires are turned into lasting changes that will better protect our residents and neighborhoods into the future.”

Altadena resident Zaire Calvin — whose sister died in the fire and whose own home burned down — said the report feels like another “slap in the face.” He said he wanted to see details on any mistakes that may have been made. But reading the report, he felt blame was once again largely placed on unprecedented fire conditions.

“A  community that's already down, a community that's fighting for their lives, a community that's fighting all of the people trying to take property from them — at some point you just want accountability,” Calvin said.

L.A. County Supervisor Kathryn Barger, who represents Altadena, said in a prepared statement that the “investigation should not be interpreted as dismissing the experiences of residents. Public trust requires both accountability and a willingness to learn from every aspect of a disaster response.”

Citygate Associates, which produced an after-action report on the 2018 Woolsey Fire, used interviews, operational records, dispatch records and internal communications to analyze decisionmaking between 9 p.m. on Jan. 7, 2025, and 6 a.m. the following day.

Some of the main findings include the following:

• With aircraft grounded by  high winds, “Incident Command was forced to fight a fire while blind to its movements.” 
• Evacuation decisions were not based on “race, age or socioeconomics.” 
• “Evacuation planners who created the evacuation zone areas well before the fire tried to use, where possible, major north/south and east/west streets. … Thus, Lake Avenue was a natural, very long street that could be utilized as an anchor for creating evacuation zones.” 
• Other fire timeline reviews cite reports of fire moving westward between 11 p.m. and just before midnight, but Citygate staffers write that strained resources were focused on the eastern front of the fire at that time, which was the direction the fire was initially spreading, and that “fire progression maps … do not show the the Eaton Fire directly impacting western neighborhoods at that time.” 
• The fire initially spread westward more slowly, and did not escalate significantly until early in the morning on Jan. 8.
• Reports of fires before 1 a.m. west of Lake Avenue were likely a result of downed power lines.
• By 2 a.m., radio reports indicated embers were being cast deeper into Altadena. 
• Discussions to expand evacuation orders west started at 2:18 a.m., with evacuation orders being sent to residents west of Lake by 3:25 a.m. 
• The main fire front crossed west of Lake Avenue by about 5:15 a.m.

Huntington Beach must pay $50,000 for each month it continues to fail to comply with the state’s mandate to zone for more housing, according to a recent court ruling. For several years now, the city has been waging a court battle against the state's order to make way for 40,000 new homes.

The judge ruled that the city should be penalized $10,000 per month going back to January 2025, and then fined $50,000 per month, starting next month, until the city gets a compliant housing element approved.

The backstory

State law requires California cities and counties to plan for enough housing to meet the expected demand over an eight-year time period, including for low-income housing. Huntington Beach, citing its independence as a charter city, has fought its most recent housing allocation all the way up to the U.S. Supreme Court, which declined to review the case last year.

Does the state require cities to actually build that many homes?

No. Cities are not required to actually build housing, but rather to make sure their zoning and land use codes accommodate the amount of housing assigned to them through what’s known as the Regional Housing Needs Assessment (RHNA).

What does the city say?

In a statement, Casey McKeon, the city’s mayor, said the city “strongly opposes these penalties and will continue fighting for the rights of our residents and for the principle of local control against ongoing efforts by the Attorney General to centralize land use authority in Sacramento.”

Is Huntington Beach an outlier?

Yes. Huntington Beach is an outlier in its aggressive fight against the state housing mandates. More than 90% of California’s 539 jurisdictions are in compliance with the state requirement to plan for the amount of housing assigned to them through the latest RHNA cycle.

What’s next?

The city recently posted draft revisions to its housing plan — for the first time since 2021. That’s significant because the city’s efforts to come into state compliance have been paused for years.

One complication with compliance: Huntington Beach residents voted to require any major changes to the city’s zoning, including its state-mandated housing plan, to be put up for a public vote. That could mean more delays in coming into state compliance, and consequently, more fines, at a time when the city is facing a budget crunch.

During a press conference following a shooting at the San Diego Islamic Center, San Diego Police Department Chief Scott Wahl confirmed three adult victims at the center and the two suspects are dead.

Police said the suspects were found dead in the vehicle nearby. They were 17 and 19 years old. The motivation behind the shooting is unknown at this time.

Wahl said in 28 years, this is the most dynamic and impressive response he's seen in policing with help coming from agencies all over the county.

Imam of the Islamic Center of San Diego Taha Hassane said the center stands in solidarity "with all of the families in our community here and all the mosques and places of worship" in San Diego.

"This is something that we never expected, and I would also like to thank all the people who contacted us from all over the country and overseas to offer their condolences."

San Diego Mayor Todd Gloria was also present at the news conference.

"We will do anything it takes to make sure you feel safe in this city," Gloria said.

In a statement, the Council on American-Islamic Relations-San Diego Executive Director Tazheen Nizam said:

“We strongly condemn this horrifying act of violence at the Islamic Center of San Diego. Our thoughts are with everyone impacted by this attack. No one should ever fear for their safety while attending prayers or studying at an elementary school. We are working to learn more about this incident and we encourage everyone to keep this community in your prayers."

The active shooter situation was reported at 11:43 a.m. at ICSD in the 7000 block of Eckstrom Avenue in Clairemont, according to SDPD.

The department is asking people to avoid the area.

A reunification location for those impacted by the incident has been established at 4125 Hathaway Street.

According to our news partner ABC 10News, authorities shut down northbound and southbound Interstate 805 at Balboa Avenue due to the law enforcement activity.

The San Diego Unified School District confirmed several campuses were placed on lock down. SDUSD spokesperson James Canning said lockdowns are gradually being lifted but schools closest to the Islamic Center will be the last to have their lockdowns lifted.

The Islamic Center is the largest mosque in San Diego County. The center holds five daily prayers.

In California’s upcoming June primary election, you’ll have the opportunity to cast your ballot for any of the candidates for governor, regardless of which party you’re registered with. The top two vote-getters advance to the general election.

Known as a “jungle primary,” this system is different from how most states handle their primary elections.

This year, Democrats raised the alarm that two Republican gubernatorial candidates may move to the general election, locking out Democrats despite outnumbering Republican registered voters almost two to one. That’s because the crowded field of Democratic candidates threatens to split the party’s vote. Until recently, multiple polls have shown the two Republicans, former Fox News host Steve Hilton and Riverside County Sheriff Chad Bianco, polling at the top of the race.

Driven in part by these concerns, critics of the top-two primary have now filed a ballot initiative that would repeal this system and return California to party-based primaries, potentially as early as 2030.

But how does this top-two arrangement work? Why does California do things this way? And what are the chances of voters choosing between two GOP candidates for governor in November?

How does California’s top-two primary system work?

In a traditional closed primary, such as in presidential races, voters can only choose among candidates from their own party: That is, say, registered Democrats could only vote for Democratic candidates.

But in a top-two primary, all candidates from all parties appear on a single ballot open to any registered voter. The two candidates with the most votes in that primary then move on to the general election, even if they’re from the same party.

Kim Alexander, president and founder of the California Voter Foundation, said this is an even bigger concern for third parties in the state.

“One of the unfortunate byproducts” of California’s jungle primary system, Alexander said, is how “it’s really shut out a lot of minor parties from the general election and they run the risk of being kicked off the ballot altogether.”

“Because if you don’t have candidates appearing on ballots at a certain pace, then you can’t remain an official party,” she said.

Does this really mean Californians might not get a Republican vs. Democrat race for governor in November?

That’s correct: Under the top-two primary system, the November contest could be an intraparty fight.

That scenario has worried many California Democrats. With seven top Democrats crowding the field, there’s a risk of fracturing their party’s vote. Meanwhile, if enough Republican voters back both Hilton and Bianco to push them both into the top two, California could be locked into an all-Republican general election for governor.

“California’s leadership on the world stage is significantly harder if a Democrat is not elected as our next Governor,” Hicks wrote in an open letter.

None of the contenders heeded his plea.

However, the likelihood of Republicans shutting Democrats out of the November election has decreased since President Donald Trump endorsed Hilton in April. A clear front-runner could unify Republican voters behind Hilton and open the door for a Democrat to claim the second spot in the runoff.

Plus, the most recent Emerson poll now shows former Health and Human Services Secretary Xavier Becerra in the lead with 19% of likely voters for the first time in the race. Hilton and Democrat Tom Steyer are tied for second with 17%.

Becerra’s surge came after former East Bay Rep. Eric Swalwell — who was regarded as a front-runner for the gubernatorial primary — exited the race last month amid sexual assault and misconduct allegations.

Why does California have this top-two system?

Historically, California required a two-thirds vote in the Legislature to pass the state budget instead of a simple majority vote.

In 2009, Democrats needed to court Republican votes to pass the state budget. Then-state Sen. Abel Maldonado, a Republican, agreed to vote yes — but only if the Legislature put a measure on the ballot to create the top-two primary system.

Voters approved that measure, Proposition 14, in 2010, amending the state constitution.

Then-Gov. Arnold Schwarzenegger backed the measure as a way to transform state politics, forcing candidates to appeal to voters across party lines and ultimately boost more moderate politicians.

“He liked to talk about living in a post-partisan political climate,” Alexander said. “He liked the idea of candidates having to appeal to more voters than just voters of their own party, and to face competition.”

The system was also designed to give more influence to California’s no party preference voters, who make up 23% of registered voters in the state, just behind Republicans at 25%.

Which political offices in California are decided using this system?

The top-two primary applies to “voter-nominated” offices: governor and other statewide positions like lieutenant governor, attorney general, secretary of state, state treasurer, state controller, insurance commissioner and state board of equalization members.

It also covers state Senate and Assembly seats and U.S. congressional offices.

The jungle primary system does not apply to presidential elections, local and nonpartisan offices such as city council, school boards, judges, district attorneys or the superintendent of public instruction.

Which other states use this system?

Washington state was the first to adopt a top-two primary for congressional and state-level elections in 2004, but not for governor.

Unlike California, Washington allows write-in candidates in the general election — a safety valve for scenarios where one party is locked out.

A handful of other states use variations of the system. Nebraska’s legislature is nonpartisan, so it uses a top-two primary for state legislative races.

Louisiana uses a majority-vote system for statewide executive offices, state legislative seats and local offices. If a candidate receives a majority of the vote in the primary, they win outright. If not, there is a second round of voting with the top two vote-getters in November.

Alaska adopted a top-four primary in 2020 for state executive, state legislative and congressional races. An effort to repeal the state’s top-four primaries was narrowly defeated by voters in 2024 but will be on the ballot again this year.

If I’m a ‘no party preference’ voter, can I even vote in the California primary?

Yes: Any registered voter, including those with no party preference, can vote for any candidate in voter-nominated races like the governor’s contest.

The top-two primary system draws no distinction based on a voter’s party registration.

Are there any efforts to get rid of California’s jungle primary?

Driven in part by concerns that Democrats could be locked out of this year’s governor’s race, a new ballot initiative seeks to repeal California’s top-two primary system.

Democratic strategist Steven Maviglio filed the initiative, called “Undo the Top Two,” with the attorney general on May 8.
He called the jungle primary a “failed experiment.”

“The prospect of having to vote for a candidate who’s not from your party in November has really woken up a lot of voters in the state about the dangers of the top-two primary,” Maviglio said. “The chance that a Democrat would have to choose between Chad Bianco or Steve Hilton is sending a chill up the spine of a lot of Democrats.”

However, even if successful, Maviglio’s initiative won’t impact the 2026 election — since he hopes to place the measure on the 2028 ballot, with any changes taking effect no earlier than the 2030 elections.
