The Brief

Proposed rules to protect California workers from extreme heat would extend to schoolchildren, requiring school districts to find ways to keep classrooms cool.

If the standards are approved this month, employers in the nation’s most populous state will have to provide relief to indoor workers in sweltering warehouses, steamy kitchens, and other dangerously hot job sites. The rules will extend to schools, where teachers, custodians, cafeteria workers, and other employees may work without air conditioning — like their students.

“Our working conditions are students’ learning conditions,” said Jeffery Freitas, president of the California Federation of Teachers, which represents more than 120,000 teachers and other educational employees. “We’re seeing an unprecedented change in the environment, and we know for a fact that when it’s too hot, kids can’t learn.”

A state worker safety board is scheduled to vote on the rules June 20, and they would likely take effect this summer. The move, which marks Democratic Gov. Gavin Newsom’s latest effort to respond to the growing impacts of climate change and extreme heat, would put California ahead of the federal government and much of the nation in setting heat standards.

The standards would require indoor workplaces to be cooled below 87 degrees Fahrenheit when employees are present and below 82 degrees in places where workers wear protective clothing or are exposed to radiant heat, such as furnaces. Schools and other worksites that don’t have air conditioning could use fans, misters, and other methods to bring the room temperature down.

The rules allow workarounds for businesses, including the roughly 1,000 school districts in the state, if they can’t cool their workplaces sufficiently. In those cases, employers must provide workers with water, breaks, areas where they can cool down, cooling vests, or other means to keep employees from overheating.

“Heat is a deadly hazard no matter what kind of work you do,” said Laura Stock, a member of the Occupational Safety and Health Standards Board. “If you have an indoor space that is both populated by workers and the public, or in this case by children, you would have the same risks to their health as to workers.”

Heat waves have historically struck outside of the school year, but climate change is making them longer, more frequent, and more intense. Last year was the hottest on record and schools across the U.S. closed sporadically during spring and summer, unable to keep students cool.

Scientists say this year could be even hotter. School officials in Vicksburg, Mississippi, last month ended the school year early when air conditioners had issues. And California’s first heat wave of the season is hitting while some schools are still in session, with temperatures reaching 105 in the Central Valley.

Several states, including Arizona and New Mexico, require schools to have working air conditioners, but they aren’t required to run them. Mississippi requires schools to be air-conditioned but doesn’t say to what temperature. Hawaii schools must have classrooms at a “temperature acceptable for student learning,” without specifying the temperature. And Oregon schools must try to cool classrooms, such as with fans, and provide teachers and other employees ways to cool down, including water and rest breaks, when the heat index indoors reaches 80 degrees.

When the sun bakes the library at Bridges Academy at Melrose, a public school in East Oakland with little shade and tree cover, Christine Schooley closes the curtains and turns off the computers to cool her room. She stopped using a fan after a girl’s long hair got caught in it.

“My library is the hottest place on campus because I have 120 kids through here a day,” Schooley said. “It stays warm in here. So yeah, it makes me grouchy and irritable as well.”

A 2021 analysis by the Center for Climate Integrity suggests nearly 14,000 public schools across the U.S. that did not need air conditioning in 1970 now do, because they annually experience 32 days of temperatures more than 80 degrees — upgrades that would cost more than $40 billion. Researchers found that same comparison produces a cost of $2.4 billion to install air conditioning in 678 California schools.

It’s not clear how many California schools might need to install air conditioners or other cooling equipment to comply with the new standards because the state doesn’t track which ones already have them, said V. Kelly Turner, associate director of the Luskin Center for Innovation at the University of California-Los Angeles.

And a school district in the northern reaches of the state would not face the same challenges as a district in the desert cities of Needles or Palm Springs, said Naj Alikhan, a spokesperson for the Association of California School Administrators, which has not taken a position on the proposed rules.

An economic analysis commissioned for the board provided cost estimates for a host of industries — such as warehousing, manufacturing, and construction — but lacked an estimate for school districts, which make up one of the largest public infrastructure systems in the state and already face a steep backlog of needed upgrades. The state Department of Education hasn’t taken a position on the proposal and a spokesperson, Scott Roark, declined to comment on the potential cost to schools.

Projections of a multibillion-dollar cost to state prisons were the reason the Newsom administration refused to sign off on the indoor heat rules this year. Since then, tens of thousands of prison and jail employees — and prisoners — have been exempted.

It’s also unclear whether the regulation will apply to school buses, many of which don’t have air conditioning. The Department of Industrial Relations, which oversees the worker safety board, has not responded to queries from school officials or California Healthline.

Libia Garcia worries about her 15-year-old son, who spends at least an hour each school day traveling on a hot, stuffy school bus from their home in the rural Central Valley community of Huron to his high school and back. “Once my kid arrives home, he is exhausted; he is dehydrated,” Garcia said in Spanish. “He has no energy to do homework or anything else.”

The California Federation of Teachers is pushing state lawmakers to pass a climate-resilient schools bill that would require the state to develop a master plan to upgrade school heating and air conditioning systems. Newsom last year vetoed similar legislation, citing the cost.

Campaigns to cool schools in other states have yielded mixed results. Legislation in Colorado and New Hampshire failed this year while bills in New Jersey and New York were pending as of June 6. Last month, a teachers union in New York brought a portable sauna to the state Capitol to demonstrate how hot it can get inside classrooms, only a quarter of which have air conditioning, said Melinda Person, president of New York State United Teachers.

“We have these temperature limits for animal shelters. How is it that we don’t have it for classrooms?” said Democratic New York Assembly member Chris Eachus, whose bill would require schools to take relief measures when classrooms and buildings reach 82 degrees. “We do have to protect the health and safety of the kids.”

Extreme heat is the No. 1 weather-related killer in the U.S. — deadlier than hurricanes, floods, and tornadoes. Heat stress can cause heatstroke, cardiac arrest, and kidney failure. The Centers for Disease Control and Prevention reported 1,600 heat-related deaths occurred in 2021, which is likely an undercount because health care providers are not required to report them. It’s not clear how many of these deaths are related to work, either indoors or outdoors.

California has had heat standards on the books for outdoor workers since 2005, and rules for indoor workplaces have been in development since 2016 — delayed, in part, because of the covid pandemic.

At the federal level, the Biden administration has been slow to release a long-awaited regulation to protect indoor and outdoor workers from heat exposure. Although an official said a draft is expected this year, its outlook could hinge on the November presidential election. If former President Donald Trump wins, it is unlikely that rules targeting businesses will move forward.

The Biden White House held a summit on school sustainability and climate change in April, at which top officials encouraged districts to apply an infusion of new federal dollars to upgrade their aging infrastructure. The administration also unveiled an 18-page guide for school districts to tap federal funds.

“How we invest in our school buildings and our school grounds, it makes a difference for our students’ lives,” Roberto Rodriguez, an assistant secretary at the U.S. Department of Education, said at the summit. “They are on the front line in terms of feeling those impacts.”

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.
