The Brief

The most important stories for you to know today
  • Cool materials may help us adapt to a hotter norm

    Kids play on a basketball court at a park in Pacoima that's been coated with "cool paint" that lowers surface temperatures and may help cool the community as a whole.

    Topline:

    "Cool" coatings on streets and roofs can dramatically reduce surface temperatures and potentially help cool neighborhoods. A pilot project in Pacoima aims to determine by how much.

    Why it matters: While planting trees, shade and green space as well as improving housing are long-term solutions, cool pavement can be installed quickly and easily and have an immediate effect. As extreme heat rapidly worsens, L.A. and many cities are investing in it. But the technology is new and it's unclear how much it can help.

    Caveats: The type of cool coating matters. Research out of UCLA found the asphalt-based reflective coatings the city of L.A. has used can actually make it hotter immediately above the surface … where people are. The coating in this area of Pacoima is acrylic-based, and preliminary research shows it doesn’t have that impact.

    As temperatures climbed on a recent afternoon in Pacoima, a local park bustled. Kids splashed in the rec center pool and shot hoops on a basketball court. Adults relaxed in the shade of trees. A vendor sold ice cream.

    Are Cooling Materials A Solution To Fight Urban Heat?

    Nine-year-old triplets Enam, Efemor and Eyako come to the park pretty much every day in the summer with their mom.

    Efemor tried to catch a breeze on a playground swing.

    "We saw it was 102, and to me that's pretty hot and doesn't make me want to do much," Efemor said.

    Already in their short lives, Enam said they’ve noticed a change in the weather. 

    "I feel like it gets pretty hotter, like kind of every year," she said. The last eight years have been the hottest on record globally, according to the World Meteorological Organization.

    Cool pavement in one of L.A.'s hottest neighborhoods

    Pacoima is one of the hottest neighborhoods in L.A. And the climate crisis is pushing average temperatures higher, and driving longer and hotter heat waves. All our buildings and pavement only make it worse.

    Last year, grassroots group Pacoima Beautiful partnered with roofing company GAF to test how “cool pavement” might help. They painted 10 square blocks of streets, the park’s parking lot and basketball court, as well as an elementary schoolyard.

    Cool pavement is among some types of materials that reflect solar radiation, instead of absorbing it. These coatings can also be used on rooftops and other surfaces exposed to the sun’s heat.

    Eliot Wall, GAF’s cool pavement project director, pointed a thermometer at the ground.

    "Here it's 132 degrees on this coated surface," he said.

    We walk to an uncoated portion of the road. It’s 10 degrees hotter on regular old asphalt.

    Why heat doesn't just go away

    But cooler surface temperatures don’t automatically mean cooler communities, said V. Kelly Turner, a UCLA heat researcher.

    "You can't make heat go away," Turner said. "You can only transfer that energy."

    Her research found that cool pavement applied in L.A. may dramatically reduce surface temperatures, but can actually increase the air temperature just above the surface, where people are.

    If the goal is cooler surface temperatures on a sidewalk so children or pets don't burn their feet as easily, a reflective coating might make sense. But if the goal is to reduce the heat load on people, planting trees or providing shade — from either trees or structures — could be more effective, Turner said.

    "Shade cools surfaces as well and it also has a much larger effect on cooling the body," said Turner.

    Cool pavement is no silver bullet, but it’s relatively quick and cheap to apply and can have an immediate effect (GAF paid for the project in Pacoima). Wall said GAF's proprietary blend of acrylic-based rather than asphalt-based cool paint doesn’t have that same heating impact above the surface.

    It's also been tested by the L.A. Bureau of Engineering for grip in wet weather and performs just as well as normal asphalt. And GAF designed it to be more durable than traditional asphalt coatings, according to the company.

    GAF uses a modified electric golf cart to take all kinds of temperature readings, from surface to air to what's called mean radiant temperature, which is an ideal measurement for how humans will physically experience heat — and the main measurement used in Turner's study identifying heat load.

    But preliminary research by GAF — that has yet to be confirmed by outside researchers — found the coatings helped cool the air temperatures for the 10-block area by three degrees during the record-long and hot heat wave in early September 2022.

    "What we're seeing is the overall neighborhood effect that the air itself is cooler and that's even actually shifting with the wind downstream," said Wall.

    GAF research found that during some of the hottest days, the area with cool paint was 3 degrees cooler than other areas, and wind even helped spread that cool air around.

    What's next in Pacoima

    Melanie Paola Torres, a community organizer with grassroots group Pacoima Beautiful, which leads the community engagement piece of the project, said community members are feeling a difference — and want more.

    "We’ve seen things that do work, so we just keep hoping to add and stack onto that and really create a climate-resilient community," she said.

    Back at the playground, the triplets and I carry out our own science experiment. (I did get their mother’s permission.)

    The rubber underneath the swings and play structure measures at 172 degrees. Then we run over to the basketball court, bright with Dodger blue “cool paint.” Its surface is 40 degrees cooler.

    Eyako sums up our findings.

    "It used to be really hot like fire, and now it's like cooler and it's much more better for people to play basketball here," he said.

    Still, cool coatings, though promising, require further research.

  • Forecasters say this year's will be "very strong"

    Topline:

    Federal forecasters say this year the planet could see the strongest El Niño event on record. It's already being called "Super El Niño" and even "Godzilla El Niño." El Niño is a natural climate pattern that has far-reaching impacts across the planet, potentially affecting hundreds of millions of people.

    Why now: NOAA forecasters say this year's El Niño will fall into the "very strong" category. It's measured by the temperature of the ocean in a particular region off South America. The warmer the water, the stronger the El Niño. When that water is more than 2 degrees Celsius warmer than average, it qualifies as a "very strong" El Niño.

    The backstory: El Niño occurs every two to seven years. It develops when a vast amount of water in the eastern Pacific Ocean warms up around the equator. That water releases massive heat, redistributing warmth from the ocean to the atmosphere. That shifts weather patterns around the world.

    What's next: El Niño also shifts rainfall patterns globally, raising the chances for destructive flooding in some parts of the world. Other regions get drier, exacerbating droughts. Both impacts can be catastrophic to agriculture around the world. The United Nations World Food Programme estimates that El Niño could push at least 49 million more people into acute food insecurity by the end of 2027.

    Federal forecasters say this year the planet could see the strongest El Niño event on record. It's already being called "Super El Niño" and even "Godzilla El Niño." El Niño is a natural climate pattern that has far-reaching impacts across the planet, potentially affecting hundreds of millions of people.

    Where those impacts happen can vary drastically from one El Niño to the next. Here are the basics of what this historic event could bring.

    What is El Niño?

    El Niño occurs every two to seven years. It develops when a vast amount of water in the eastern Pacific Ocean warms up around the equator. That water releases massive heat, redistributing warmth from the ocean to the atmosphere. That shifts weather patterns around the world.

    The flip side of El Niño is a La Niña, which is marked by relatively cool water in the tropical Pacific around the equator. These events are responsible for some of the biggest weather variability the planet experiences.

    Loading...

    El Niño is like dropping a rock in a pond, says Daniel Vimont, professor of atmospheric and oceanic sciences at the University of Wisconsin-Madison. "Even though you're not where the rock hit, you still may feel the effects of those waves," he says. "El Niño is the same thing, except it's an enormous rock in our entire Earth's system, and we feel the response."

    How strong is it?

    Sure, "Godzilla El Niño" is catchy, but technically, NOAA forecasters say this year's El Niño will fall into the "very strong" category. It's measured by the temperature of the ocean in a particular region off South America. The warmer the water, the stronger the El Niño. When that water is more than 2 degrees Celsius warmer than average, it qualifies as a "very strong" El Niño.

    The last strong events were in 2015-16, 1997-8 and 1982-83. El Niños typically peak in November and December, but already, this El Niño is the strongest ever measured for this time of year. NOAA forecasters expect it to last through early 2027.

    What will the impacts be globally?

    All that added heat in the atmosphere raises temperatures globally. El Niño years tend to be the hottest on record. Forecasters say this year may get close to taking the top spot, but it's very likely that temperature records could fall in 2027. The planet is already warmer due to climate change, because emissions from burning fossil fuels are trapping more heat in the atmosphere.

    El Niño also shifts rainfall patterns globally, raising the chances for destructive flooding in some parts of the world. Other regions get drier, exacerbating droughts. Both impacts can be catastrophic to agriculture around the world. The United Nations World Food Programme estimates that El Niño could push at least 49 million more people into acute food insecurity by the end of 2027.

    What will the impacts be in the U.S.?

    In El Niño years, the southern U.S. tends to see more intense rainfall because the jet stream shifts to the south. That raises the risk of floods along rivers and in cities. Still, in the Southwest, more rain could alleviate drought and recharge underground aquifers.

    "El Niño tends to juice up those storms so that you get more really strong rain events," says Martin Hoerling, meteorologist and adjunct lecturer at the University of Colorado Boulder. "So if you were running a deficit in your water supply, a big El Niño, especially like the one we're having, can really get you into recovery mode that otherwise might have taken you years."

    The northern half of the country gets warmer and drier, something that could exacerbate the current drought in the Intermountain West. Some states experience mixed effects during El Niños, like California. The state saw historic flooding in the 1997-98 El Niño, but was drier than average during the 2015-16 one. Climate experts say the current El Niño is so strong, it's more likely California will experience extreme rain.

    El Niños can also lead to fewer hurricanes in the Atlantic Ocean, since it's more difficult for the storms to form. In the Pacific Ocean, hurricanes can get more frequent, fueled by warmer ocean water. Already this year, hurricanes have intensified rapidly in the Pacific, and Hawaii has had close calls with several hurricanes that brought destructive rain and wind.

    Can we blame it all on El Niño?

    Certain weather changes are common during El Niños, but there are no guarantees that extreme weather events this winter will match those predictions for every region.

    "El Niño is like loading the dice," Vimont says. "While we're loading the dice for a certain type of response from El Niño, we still know that in any given year, there are still natural fluctuations that may mask that or cause the response to be slightly different than what we might expect."

    In addition to that natural variability, weather events are also being affected by climate change. The most intense storms are already producing more rainfall in most of the U.S., since a warmer atmosphere can hold more water vapor. Heat waves and droughts are also getting more intense due to rising temperatures. Climate experts say El Niño and climate change impacts will both play out this winter, but while El Niño will fade, the effects of climate change will continue.

  • Inside Hollywood Burbank Airport’s spiffy terminal
    A wide view of the new Hollywood Burbank Airport sign that's connected to a large rounded overhang across the facility.
    Hollywood Burbank Airport's new sign.

    Topline:

    Hollywood Burbank Airport’s new terminal is ready for prime time and slated to open to the public next week. Here’s what you can expect.

    What is it like? The new billion-dollar terminal has LAX’s modern feel, but presumably without the headaches. It’s replacing the old terminal that opened in 1930.

    Why was it needed? The airport needed improvements to meet FAA safety standards and state building requirements. The expanded space also allows for all gates to fit the large, modern planes.

    Read on…. to see what the new terminal looks like inside.

    Fans of Hollywood Burbank Airport have a new way to rag on LAX-ers.

    Burbank’s ambitious new terminal building has been completed on time and on budget. The long-awaited structure, known as the Elevate BUR project, is ready for prime time.

    It’s slated to open to the public on Oct. 13, with a new entrance at Winona Avenue and Hollywood Way. On Monday, LAist got a look inside.

    Why now?

    The $1.3 billion terminal is a decade in the making. The project comes from Burbank’s Measure B, which voters passed in 2016.

    Burbank Mayor Tamala Takahashi said the new building will replace the terminal that opened in 1930, which will eventually be demolished.

    “ The old building is not to code, so it can’t be reused. It’s too close to the airstrip. That’s why we had to do this in the first place,” she said.

    The new facility is more than 50% larger. Plus, it has a slate of improvements needed to meet FAA safety standards and state building requirements. That includes new seismic and accessibility features and more runaway space.

    Takahashi said the new terminal will open up  capacity because all of the gates will be able to accommodate modern planes.

    “What that means is that we’re going to have the same number of flights, the same number of planes, the same number of gates, but more people going through the airport every day,” she said.

    There’s one thing travelers can count on to stay the same: You’ll still be able to board your plane on the tarmac.

    The Hollywood touch

    Tyron Hampton, president of the Burbank-Glendale-Pasadena Airport Authority, which owns the airport, said it’s time everyone knows about L.A.’s best insider tip for flying.

    “ This is no longer a secret,” he said. “We want people to come here. We want people to see this experience.”

    Hampton said the new building has space for more amenities, which feature local retailers like Jones Coffee and Octavia’s Bookshelf.

    Art is also woven into the design. Brent Kelley, who worked on the architecture at Corgan, said one of their themes was classic Hollywood.

    For example, small dots on the ceiling are meant to evoke Marilyn Monroe’s glimmering dress during her iconic “Happy Birthday, Mr. President” moment.

    A “silver screen” canopy extends across the building outside, alongside an installation that honors the time the buildings were covered in camouflage during World War II.

    Republican gubernatorial candidate Steve Hilton speaks at a press conference outside the California attorney general’s office in Sacramento on Aug. 5, 2025.

    Topline:

    Steve Hilton, the Republican candidate for California governor, will speak with a panel of Los Angeles journalists Tuesday afternoon, making his case for why a deeply Democratic electorate should trust him to tackle the state’s biggest challenges.

    The details: The Los Angeles Times and LAist are co-hosting the candidate forum, which will be livestreamed at 4 p.m. and re-broadcast on LAist 89.3 FM at 7 p.m.

    The issues: LAist housing correspondent David Wagner and L.A. Times journalists Mark Z. Barabak and Seema Mehta will moderate the approximately hour-long event. They will ask Hilton about his plans for addressing topics such as housing affordability, homelessness, climate change and the state’s relationship with the federal government (President Donald Trump has endorsed Hilton). The event will also include questions submitted by readers and listeners.

    Where’s Becerra? Democratic front-runner Xavier Becerra was invited to participate in the forum, but his team has not responded. The invitation still stands.

  • Emerging tech a worry for students

    Topline:

    Cal State has rolled out AI initiatives across campuses, including faculty grants and credentialing programs, to better prepare students for the future workforce.

    Why it matters: Last year, CSU became the nation’s first public university system to pay for students’ access to ChatGPT Edu. It has awarded over $3 million in grants for faculty to experiment with how to use AI in classrooms. Several campuses now train students in how to responsibly use the technology. Those measures are all pieces of CSU’s strategy to prepare students for a future labor market reshaped by AI.

    The backstory: The investment in AI has come under criticism from some CSU faculty, and some students remain skeptical of the value of knowing how to use AI even as most are concerned the developing technology will threaten their chances of landing a job and keeping it. The success of CSU’s AI strategy will depend on the extent to which AI affects the workforce that today’s college students will soon enter.

    California State University is betting that artificial intelligence will transform the workplace — and that its 470,000 students need to learn how to use it before they graduate.

    Last year, CSU became the nation’s first public university system to pay for students’ access to ChatGPT Edu. It has awarded over $3 million in grants for faculty to experiment with how to use AI in classrooms. Several campuses now train students in how to responsibly use the technology.

    Those measures are all pieces of CSU’s strategy to prepare students for a future labor market reshaped by AI. But the investment in AI has come under criticism from some CSU faculty, and some students remain skeptical of the value of knowing how to use AI even as most are concerned the developing technology will threaten their chances of landing a job and keeping it.

    The success of CSU’s AI strategy will depend on the extent to which AI affects the workforce that today’s college students will soon enter.

    Hiring is frozen in many sectors right now as employers wait to see the true extent artificial intelligence will change the labor market, said Eric Bettinger, a leading education economist with Stanford Graduate School of Education. But it’s not clear if the slowdown in the labor market can be attributed to AI.

    As with previous emerging technologies, AI is forcing employers to decide whether they should replace workers with the technology, or hire more employees who can leverage AI to be more productive, Bettinger said.

    New graduates are facing a difficult labor market, considering the unemployment rate for this population has steadily risen since 2022, according to the Federal Reserve Bank of New York.

    “The reality is that the world outside of school isn’t slowing down, and we need to prepare our students for that reality,” James Frazee, San Diego State University’s vice president for information technology, told EdSource.

    Students worry AI is taking their future jobs

    Ismaeel Malik, a San Jose State University justice studies student, said he worries about AI taking over jobs in his desired field.

    “Entry-level jobs are work that people don’t want to do,” Malik, who will graduate next spring, told EdSource. Malik said he doesn’t think AI proficiency will make it easier to win a position out of college.

    Other San Jose State students who spoke with EdSource say they think some majors will be more affected than others. San Jose State prenursing student Jade Goodewin said the “hands-on” part of her preferred future career seems fairly AI-proof. But second-year student Vien Tang, who is studying advertising, said that AI could replace some of the work of entry-level jobs in the advertising industry.

    “It’s definitely a possibility, because I think a lot of companies try to cut costs,” Tang said. “There’s a likelihood of that happening.”

    Given SJSU’s proximity to Silicon Valley and many companies whose technologies are reshaping the workforce, the university hopes to be a leader in AI adoption, said Sandra Hirsh, special assistant to the university’s provost for AI initiatives.

    “We need to be preparing students with whatever the latest opportunities are, but also prepare students for the fact that change and evolution are going to continue to happen,” she said.

    Hirsh said companies want graduates to have a basic understanding of AI and how to use it in their work. Despite the nebulous changes happening in the job market, companies that hire SJSU graduates have told university leaders that students also need skills in leadership, inventiveness and ethics.

    The CSU system is paying $13 million a year to provide ChatGPT Edu to all 470,000 CSU students.

    Artur Gafurov, president of the California State Student Association and a fourth-year student at San Jose State, said many students appreciate access to AI tools like ChatGPT Edu, but don’t necessarily know how to use them responsibly and effectively.

    “I know a lot of students who are taking it upon themselves to learn a bit more about the tool and restrict themselves with how they use it,” Gafurov said.

    Some question the value of AI initiatives 

    Other private and public universities have signed agreements with companies such as OpenAI to give students access to large language models, including ChatGPT Edu. Large public university systems, such as State University of New York, have also developed systemwide AI policies, and some colleges, such as Northwestern University, have launched AI majors.

    But not everyone at CSU has embraced the growing use of AI on campuses. Some professors pushed back on the OpenAI deal after CSU signed it in early 2025. Martha Lincoln, an anthropology professor at San Francisco State University, said CSU administrators did not clearly explain how AI would be used on campuses and in classrooms by students.

    “What will students be doing with AI that’s so valuable? If it’s so valuable to them professionally, educationally, where is that value and what does it look like?” Lincoln said.

    Martha Kenney, a professor in the SFSU Department of Women and Gender Studies, said CSU’s claims that AI is helping prepare students for the changing labor market are dubious because the university has not clearly identified skills young people should develop for their future careers.

    “It’s possible it has no use for our students in this way,” Kenney said.

    According to an OpenAI spokesperson, ChatGPT Edu provides students with access to the company’s latest large language model, and includes plug-ins that students and faculty can use to personalize their accounts for teaching and learning.

    University officials say providing access to tools like ChatGPT is essential to prevent a digital divide for CSU students who may not be able to afford subscriptions to these technologies.

    “We believe we’re doing the right thing to serve our mission to prepare our students for the future workforce,” said Ed Clark, CSU’s chief information officer.

    The future workforce

    Erika McEntarfer, the former commissioner of the Bureau of Labor Statistics and a policy fellow at the Stanford Institute for Economic Policy Research, said some experts in recent years have forecast that AI would wipe out white-collar workers’ jobs. There’s little evidence that has happened, she said.

    It’s difficult for universities to predict which skills will be in demand in the future, she said, but colleges should prepare their students for disruptions to their careers. She noted that roughly 60% of today’s jobs didn’t exist in 1940.

    Universities need to prepare students for a tough labor market, and not just because of AI, McEntarfer said. The recent rise in the unemployment rate among new graduates started before ChatGPT was introduced in 2022, she said.

    McEntarfer’s advice to recent or soon-to-be graduates is to develop skills that make you a good “human” worker, such as small talk, showing up to work on time and meeting the needs of company leaders.

    “With AI you need to make sure you’re using it as a personal trainer, not a human forklift,” McEntarfer advised future college graduates. “Hopefully that’s what colleges are doing.”
