  • Volunteers in Altadena refuse to let lights go out

    Scott Wardlaw, president of the Altadena Christmas Tree Lane Association, pulls on a string of lights during a 2024 light installation.

    Topline:

    Altadena’s century-old Christmas Tree Lane returns Saturday for its first lighting since the Eaton Fire and a ceremony that will acknowledge the community’s loss. Organizers say the display will shine brighter thanks to the addition of thousands more bulbs.

    Background: Celebrated as the country’s largest and oldest outdoor lighting display dating back to 1920, the spectacle is created entirely by volunteers painstakingly stringing up lights with ropes and pulleys over the course of several months.

    Read on ... for details of the lighting ceremony and the history of the tradition.

    Over its 105-year history, Altadena’s Christmas Tree Lane has fallen dark only in extraordinary times — as World War II raged and during a national energy crisis in the 1970s.

    This year, as Altadena weathers its greatest test post-Eaton Fire, the thought of keeping the storied lane unlit was considered.

    But only briefly.

    “We did talk about whether it would be depressing because of what was lost,” said Scott Wardlaw, president of the Christmas Tree Lane Association. “But people were urging us to do it again and saying ‘Please put the event on and put those lights up.’”

    Starting Saturday, more than 20,000 lights will roar back on the deodar cedars towering over a nearly mile-long stretch of Santa Rosa Avenue, right on the edge of the burn scar.

    Some of the holiday lights, which still wrapped around the trees at the time of the fire, were damaged along with branches — not by embers but by the windstorm that fanned January’s fire. At the northern end of the lane, some homes were scorched.

    But miraculously, not one of the 153 deodars, some as high as 130 feet, were lost.

    “This will be a symbol of Altadena's rebirth, and us coming together again as a community,” Wardlaw said.

    A homecoming

    Celebrated as the country’s largest and oldest outdoor lighting display dating back to 1920, the spectacle is created entirely by volunteers painstakingly stringing up lights with ropes and pulleys over the course of several months.

    Every year, thousands of visitors from all over Southern California travel to Altadena from December into early January to drive under the canopy of lights.

    “It's just the simplest thing ever — just lights in a tree,” said Mikayla Arevalo, who coordinates volunteers for the association. “I feel like that's what made us so special. We're not bright. We're not flashy.”

    Volunteers with the Christmas Tree Lane Association started to string lights in September.

    This being the lane’s first lighting after the Eaton Fire, organizers expect turnout at Saturday’s kickoff event at 6 p.m. will be larger than usual.

    “We wanted to use this celebration as a moment for community members to come back to Altadena to see their neighbors and their friends, as many people are in different areas now and no longer together,” Arevalo said.

    The ceremony will include new elements, including a moment of silence for the 19 Altadenans who died in the fire.

    And Altadenans whose families have long volunteered on Christmas Tree Lane will take part in the switch-on of the lights alongside L.A. County Supervisor Kathryn Barger, who represents Altadena in the 5th District.

    Brighter than ever

    When the lights come back on Saturday, return visitors may notice the display glowing brighter than ever before. A donation of an undisclosed amount from the Walt Disney Co., which has employees from Altadena, was used to pay for thousands of extra lights.

    Each tree now carries five to six long strings of clear, red, blue, green and yellow lights, up from four or five.

    Immediately after the fire, there were questions whether it’d be safe for volunteers to string lights on the trees amid the ash and debris.

    But the tree lighting association said it got the all-clear from the county, which also gave volunteers more than 400 protective suits as they embarked on another round of installations in mid-September.

    Leaders worried that they wouldn’t get the same number of volunteers as they did in past years because much of the town had been forced out by the fire. But they saw close to 200 volunteers who showed up on weekends over several months to get the job finished before the 10 weekends it typically takes.

    A tradition that endures

    That kind of community resilience fits a tradition that has anchored Altadena for more than a century.

    Christmas Tree Lane owes its beginnings to the Woodbury family, early Altadena settlers, according to a documentary about the tradition created by the association, Altadena Historical Society and the Altadena Libraries.

    After returning from Italy, younger brother John Woodbury became enamored with the deodar cedar and ordered seeds from the U.S. Department of Agriculture to plant along the family’s access road — now Santa Rosa Avenue.

    By the early 1900s, the trees had matured into a green corridor, drawing visitors who strolled and drove beneath the shade.

    The idea to illuminate those cedars came in 1920, when the newly formed Pasadena Kiwanis Club adopted it as one of its first civic projects.

    Within a matter of years a regional sensation was gaining national attention. In 1937, a live radio broadcast of the lighting was broadcast to listeners across the country.

    The lane’s evolution continued in 1956 as volunteers formalized into the Christmas Tree Lane Association, which worked year-round maintaining the lights, caring for the trees, and raising money for repairs.

    The lane’s long history shows that interruptions have been the exception.

    During World War II, the lane went unlit as part of mandated blackouts ordered by the government to prevent enemy ships and planes from locating targets.

    In 1973, the lane fell dark again amid a national energy crisis that saw President Richard Nixon discouraging the use of ornamental outdoor lighting.

    But during another difficult juncture for the country during the height of the pandemic in 2021, the light display returned thanks to committed volunteers self-distancing as they decorated the trees.

    Now after the Eaton Fire, the display is back because some of those same volunteers refuse to let the lights go out.

    “The thing that's impressive to me, that symbolizes Christmas Tree Lane — it's the people,” Wardlaw said.

    Some 31,000 nurses and healthcare workers employed by Kaiser Permanente will begin an open-ended strike in California and Hawaii on Monday.

    Why it matters: California has the largest share of picketing Kaiser workers, with about 28,000 employees.

    Why now: The health system and the union representing Kaiser workers — United Nurses Associations of California & the Union of Health Care Professionals — have been negotiating for a new labor contract for months.

    Some 31,000 nurses, pharmacists and healthcare workers employed by Kaiser Permanente will begin an open-ended strike tomorrow in California and Hawaii, with 28,000 of those workers in California alone.

    The health system and the union representing Kaiser workers — United Nurses Associations of California & the Union of Health Care Professionals — have been negotiating for a new labor contract for months. Core bargaining issues include wages for nurses, understaffing and retirement benefits.

    "Staffing's been a big problem,  wages, working conditions ... and that's just to name a few," said Peter Sidhu, Executive Vice President of UNAC/UCHP. "We will have the largest open-ended healthcare strike in U.S. history."

    Picketing is slated to begin at 12 local Kaiser medical facilities in the following communities: Anaheim, Baldwin Park, Downey, Fontana, Irvine, Los Angeles, Ontario, Riverside, Harbor City, Panorama City, West Los Angeles and Woodland Hills.

    Kaiser said in a statement that their hospitals and medical offices will stay open during the strikes, but some pharmacies will close.

  • How the community came together to push back plans
    In the foreground of a crowded meeting room is a sign that reads "No Data Center" held up by a woman who's face is obscured by the sign.
    Hundreds packed into Monterey Park City Hall to call for a moratorium on data centers.

    Topline:

    Monterey Park residents have been turning out in force to oppose a proposed data center, pressuring city leaders to go beyond a temporary moratorium on the facilities and consider banning data centers altogether.

    Why it matters: Data centers are rapidly spreading across L.A. County, and beyond. The response of residents in Monterey Park shows how people outside of City Hall can influence whether that growth happens.

    The project: The developer, HMC StratCap, wants to build a nearly 250,000-square-foot data center in the Saturn business park.

    The backstory: The project had been moving through City Hall for about two years before many residents learned about it in recent weeks and months, sparking a grassroots campaign that has quickly built momentum.

    What's next: During the 45-day moratorium, city staff will draft an ordinance that would ban data centers outright if approved by the City Council. Meanwhile, the developer says it will plan outreach to residents.

    Billions of dollars are pouring into data centers to power streaming services, cloud storage and the biggest energy monster of all, artificial intelligence.

    Dozens of data centers already dot the region, from El Segundo to downtown L.A. But in Monterey Park, residents concerned about the environmental and health impacts of data centers are drawing a line.

    A developer has proposed building a nearly 250,000-square-foot data center in a local business park. Last Wednesday night, hundreds of people packed City Hall to say they didn’t want it — or for that matter, any such facility.

    “No data centers in Monterey Park!” the crowd chanted.

    Residents’ immediate goal was to ensure the City Council approved a 45-day moratorium on data center development, an item added to the agenda after weeks of mounting public pressure.

    What they got, in a meeting that stretched past midnight, was the council’s commitment to draft an outright ban during the 45-day period for a later vote. “That is more than I ever could have hoped for from this meeting,” resident Steven J. Kung said. “I am shocked and a little bit overjoyed.”

    Residents organize

    Hours earlier at a rally he helped lead outside City Hall, Kung had been far more cautious.

    He expressed little faith in city officials, especially after learning that the project had been moving through the city’s planning process for about two years without his knowledge.

    Kung said he only found out about the proposal from the Australian-based developer when his husband showed him a social media post by SGV Progressive Action last month — despite their living about 1,300 feet from the proposed site.

    “I was incensed that no one had told me, especially since I lived so close,” he said.

    Kung joined a grassroots group of residents and activists called No Data Center Monterey Park, which has organized teach-ins, canvassing drives and yard sign campaigns in the weeks leading up to the vote.

    Developer's promises

    The developer, HMC StratCap, has said its proposed data center on 1977 Saturn Street would generate more than $5 million a year in tax revenue and more than 200 jobs during construction. It’s also promised to build a public park.

    But residents said that’s not worth the tradeoff of the massive energy demand of data centers, pollution from diesel backup generators and noise from cooling equipment.

    The developer counters that the generators will be strictly regulated, a “closed-loop cooling technology” will use water efficiently and noise will be “similar to a typical commercial area,” according to a handout shared with residents at Wednesday’s meeting.

    The developer has also agreed to an environmental impact report.

    Kung and others say an EIR is the least the developer should do. They say they’re also troubled by the decision to locate a data center in a city of roughly 60,000 people, more than half of them immigrants.

    “They see a small city full of Asians and Latinos, and they don’t think we’ll fight back,” Kung said. “But they’re wrong.”

    “People, not machines”

    So many people showed up that the lobby was converted into overflow space.

    Among them was Alex Leon, a mathematician who attended with his wife, a phlebotomist, and their two young daughters.

    “This has kind of been our dream, living in Monterey Park,” Leon said. “I just don’t want it to turn into an industrial farm for big data.”

    Like dozens of others, Leon wasn’t there just to watch, but wanted council members to listen. When his turn came to give comment, he met the eyes of the council members.

    “Monterey Park should be built for people, not machines,” he said. “For families, not server racks. For community life, not industrial infrastructure. This is our home, and it’s worth defending.”

    “Open and honest conversations”

    A handful of speakers supported the project, including a representative for the developer. Laziza Lambert pivoted at the podium to face the crowd.

    “We just really want to be good, long-term partners with the community and hope to have open and honest conversations,” she said, as some in the audience started to jeer.

    Residents voiced concerns that once one data center is approved, the floodgates would open, noting that the developer owns another parcel on the same street.

    But much of the anger that night was aimed at city leaders. Speaker after speaker said they had been kept in the dark.

    Katherine Torres, a real estate agent and president of the Monterey Park Women’s Club, said the organization is apolitical, but she would be sure to tell the members.

    “I swear, I’m going to spread the word about the data center because they need to know,” she said as the room erupted in applause.

    She looked at the council members with whom she was on a first-name basis.

    “I have dinner with you guys,” she said. “I go to your events. Why didn’t I know?”

    A surprise shift

    By the fifth hour, nearly 80 residents had spoken. Then it was the council’s turn to give comments before their vote on the 45-day moratorium.

    Two members said they supported going beyond a temporary pause and considering a permanent ban. Jose Sanchez’s opposition to data centers was already known to those closely following the issue. But Elizabeth Yang’s was not.

    Yang told the room that her mother and stepfather live within a mile of the proposed site.

    “I’m not going to vote for something that’s going to hurt my own family,” she said.

    She added she was disappointed the developer had not done more with outreach and information.

    “Because of all of you feeding us good information, I’m siding with no data center,” Yang said.

    The remaining residents started clapping and rose to their feet.

    What’s ahead

    The council unanimously approved the 45-day moratorium during which city staff will draft an ordinance that could ban data centers outright — a proposal that will return to the council for a vote.

    Outside council chambers, Steven J. Kung praised his fellow residents for speaking out and pushing the council to think bigger.

    “I’m so proud of Monterey Park and our residents,” he said. “The more I’m here, the more I fall in love with the people.”

    He’d celebrate that night. But then it’d be back to work, making sure the ban stands and Monterey Park keeps data centers out for good.

    The developer would not be sitting back either. Lambert, the representative for the developer, said they were moving forward with plans to host a town hall with residents in the next couple of weeks.

  • Influencers expand their scope

    Topline:

    Have you checked the weather on social lately? The weather genre online spans a wide range of sources — from amateurs with no science background to accredited meteorologists.

    Why now: Experts say that while weather influencers can help fill an information gap, platforms like TikTok, Instagram, and X tend to prioritize engagement and likes over accuracy.

    But: That means extreme weather updates on social media are often sensationalized or lack context, says experts.

    When Christian Bryson needs quick weather information, like for this weekend's massive snowstorm, he doesn't wait for the 5 p.m. local newscast. Instead, he turns to Ryan Hall.

    "It's as if he's sitting in the living room with you tracking the storm," said Bryson, a 21-year-old meteorology student at the University of Tennessee at Martin.

    Hall, who goes by "Ryan Hall, Y'all" on his social media platforms, calls himself a "digital meteorologist" and "The Internet's Weather Man." His YouTube channel has over 3 million subscribers. Hall did not respond to a request to comment about his platform.
    Hall is part of an increasingly popular genre of social media weather accounts that share information leading up to extreme weather, and then livestream for their viewers, sometimes for hours at a time. Overall, Hall offers solid information and is a good communicator with a few technical omissions, experts told NPR. But the weather genre online spans a wide range of sources — from amateurs with no science background to accredited meteorologists.
    Experts say that while weather influencers can help fill an information gap, platforms like TikTok, Instagram, and X tend to prioritize engagement and likes over accuracy. That means extreme weather updates on social media are often sensationalized or lack context, says Gary Lackmann, a professor of atmospheric science at North Carolina State University.
    "They're not going to the National Weather Service web page, they're just looking at what's in their feed," Lackmann said. "Once you start clicking on viral extreme weather stuff, then the algorithm is going to just feed you more and more."

    Rise in social media use for weather updates

    Lackmann, who is also head of NC State's department of marine, earth and atmospheric sciences, said in 2024 during Hurricane Helene, a weather disaster that swamped western North Carolina, killing 108 people, he started to see more and more people getting their weather information from social media
    He says that, in the face of extreme weather events, people need credible and authoritative sources such as the NWS.
    But with social media, sometimes "you get some kid who wants to get a lot of shares and likes and be an influencer on social media," he said.
    Matthew Cappucci, a senior meteorologist for the weather app MyRadar, has personal experience with both worlds. He worked for years at the Washington Post as a meteorologist, and now posts weather forecasts on the internet.
    Cappucci said his success on Facebook, Instagram, and X shows how rapidly people are shifting from getting their weather information from traditional news outlets versus social media.
    "Within two months, I was able to reach 60 million-plus people on social media, just on Facebook," Cappucci said
    Bryson, the 21-year-old, said Hall and other credible weather influencers use language that non-meteorologists understand and they can share information at any time of the day.
    "The fact that it's available at your fingertips," Bryson said. "I could go to Ryan Hall at 4 p.m. I'm eating my dinner and get the information that I need."

    Digital meteorology can help fill information gaps 

    There are positives to having meteorologists and credible weather sources on social media, Lackmann said. He's seen local weather influencers in North Carolina help disperse information from official outlets.

    "There's a real need for that kind of localization and personalization of weather information," Lackmann said.
    Aaron Scott, an assistant professor of meteorology at the University of Tennessee at Martin, said digital meteorology, a relatively new certification program that encompasses all forms of digital media, has an important place in the new media landscape.
    "People do trust them, and they have built rapport," Scott said. "Sometimes that can make the difference if someone's going to actually go take shelter from a tornado or not."
    Scott's department at UT Martin is now offering a digital meteorology class dedicated to teaching students how to engage with an online audience.
    Cappucci also sees the positives with his own content. Social media allows for more flexibility than on-air television, he said. He pushes back on climate misinformation or weather conspiracy theorists.

    A minefield of misinformation on social media

    But all three experts interviewed by NPR see the downsides in the way social media algorithms push the most sensationalized — not always the most accurate — information to the forefront.
    "The brightest colors, the most outlandish information will always get more following than actual truthful information," Cappucci said.
    Cappucci said the ability to make increasing amounts of money on social media can also lead to inaccurate weather information.
    "As TV viewership wanes and as salaries come down, it's easier to make up that money by posting crazy stuff online," Cappucci said.
    Meteorologists use a number of different numerical models as they predict the possible outcomes of an extreme weather event. Because of this, people can "cherry-pick" one model and sensationalize a forecast, Lackmann said.
    "You cry wolf too often, and people won't take proper precautions when there really is a high probability of an extreme event," Lackmann said.

    The effort to preserve credible weather reports

    Meteorologists and other weather professionals are grappling with how to navigate the new media landscape and prioritize accurate information, the experts said.
    NWS has increased its social media presence, Lackmann said. Experts at the American Meteorological Society have discussed a social media certification that extends beyond the digital media certification currently available.

    Scott said how the field will grapple with social media, and now AI-generated media, is "a huge question mark."
    "That's the million-dollar question," Scott said. "How do we make it? Do we have some type of badging system where you're certified, you're not? Then, who decides that?"
