Sharks are congregating at a California beach. AI is trying to keep swimmers safe | CNN

 — 

On summer mornings, local kids like to gather at Padaro Beach in California to learn to surf in gentle whitewater waves. A few years ago, the beach also became a popular hangout for juvenile great white sharks.

That led to the launch of SharkEye, an initiative at the University of California Santa Barbara’s Benioff Ocean Science Laboratory (BOSL), which uses drones to monitor what’s happening beneath the waves.

If a shark is spotted, SharkEye sends a text to the 80-or-so people who have signed up for alerts, including local lifeguards, surf shop owners, and the parents of children who take lessons.

In recent years, other initiatives have seen officials and lifeguards from New York to Sydney using drones to keep beachgoers safe, monitoring video streamed from a camera. That requires a pilot to stay focused on a screen, contending with choppy water and glare from the sun, to differentiate sharks from paddleboarders, seals, and undulating kelp strands. One study found that human-monitored drones only detect sharks about 60% of the time.

SharkEye – part research program, part community safety tool – is using the video it collects to analyze shark behavior. It’s also feeding its footage into a computer vision machine learning model – a type of artificial intelligence (AI) technology that enables computers to glean information from images and videos – to train it to detect great white sharks near Padaro Beach, close to the city of Santa Barbara.

“Automating shark detection … can (also) be really helpful for a lot of communities outside of ours here in California,” Neil Nathan, a project scientist with BOSL, who graduated from Stanford University with a master’s degree in environmental studies a few years ago, told CNN.

A rise in the popularity of drones, and the proliferation of social media, may make it seem like sharks are everywhere. It doesn’t help that warming ocean temperatures are pushing sharks into new habitats, and that juvenile great whites, which can grow to about eight to 10 feet long, like to hang out near the shore, making them more visible to beachgoers.

Yet shark attacks are rare. In 2023, 69 people globally were at the receiving end of unprovoked bites – which is in line with the average of 63 annual incidents between 2018 and 2022. Just 10 of them died, according to the Florida Museum of Natural History’s International Shark Attack File.

Although there hasn’t been a fatal attack recorded at Padaro Beach, some community members were concerned when sharks began loitering there.

That’s why SharkEye has been regularly running drone flights to monitor the coastline for about five years, once spotting 15 juvenile great white sharks in a single day.

Early tests indicate that the AI technology is already performing “incredibly well,” detecting most sharks a human can, and sometimes sharks that a human missed, perhaps because it was swimming too deep to spot easily, said Nathan.

This summer, the project began field testing its technology by pitting drone pilots against AI. Its pilot surveys the area and counts the number of sharks she spots. Then SharkEye’s model analyzes the video to see how many sharks it can find.

Today, the community alerts are based on human analysis. If all goes swimmingly, those reports may become AI-assisted – with manual monitoring and checks – by the end of the season, or the start of next summer, said Nathan. In the future, the process may even become totally automated, making it faster and potentially more accurate.

AI and wildlife

AI technologies are being harnessed in myriad ways to mitigate human-wildlife conflict. In India, AI-enabled cameras are alerting villagers when tigers are closing in on their livestock, and in Australia, technology is being used to manage some of its dangerous creatures.

Ripper Corp and academics pioneered what they say are the first shark identification algorithms in the world, which were put to use in drones a few years ago. The latest version of the software is being tested across the Australian state of Queensland, Mexico and the Caribbean to detect sharks and crocodiles.

However, AI is not yet used widely for shark detection. Surf Life Saving New South Wales, which protects dozens of beaches along the state’s coast, including Sydney’s iconic Bondi Beach, uses drones in 50 locations. But a spokesperson told CNN that their drones aren’t currently utilizing AI.

A group from one Australian university that worked on AI-enhanced shark-spotting tools wrote in 2022 that the technology can struggle when encountering conditions that weren’t present in the training data.

SharkEye plans to make its model free and available for researchers to amend or build on, and to create an AI-powered app that’s easy for people like lifeguards and drone hobbyists to run their footage through. That could help keep people safe, but also allow humans to better understand and protect sharks.

Nathan said it remains to be seen how much retraining will be required for SharkEye to expand to other locations. He’s hopeful that if drone pilots fly at the same speed and altitude, they won’t have too many issues elsewhere in California, where the coastline is similar.

Officials in Honolulu said this month that they’re considering launching a drone shark surveillance program, according to local media. If SharkEye’s technology were to be used in places like Hawaii, where tiger sharks are the biggest concern, and the hue of the water differs, more retraining might be necessary. But Nathan said that SharkEye is open to working with other localities to help adapt the model.

“Communities want to have that knowledge and that awareness so it’s easier to more safely share the water with these creatures,” said Nathan. “Sharks are an incredible species that we still are always learning new things about.”

As California’s schools struggle, governor hopefuls clash over who’s to blame — and who should fix it


Education is California’s largest state expense, consuming more than a third of the state budget through K-12 schools alone. Yet as voters prepare to choose a successor to outgoing Gov. Gavin Newsom, candidates across the political spectrum agree the system is falling short.

Governor Newsom announces free entry to many California state parks on MLK Day


Governor Gavin Newsom announced that he has directed California State Parks to offer free entry at more than 200 participating parks and beaches on Monday, the national holiday honoring Martin Luther King, Jr.

Newsom said that the action is a direct response to President Trump’s decision to remove MLK Day and Juneteenth for free entry at national parks and monuments starting this year.

“I’m encouraging all Californians to get outside on MLK Day, spend time in nature, reflect on Dr. King’s legacy, and reaffirm our commitment to advancing civil rights for all,” the Governor said in a message on the official state website.

“Providing access to the beaches is great for everyone. Everyone should have access, and days we don’t have to pay is a bonus,” said Robert Northop after finding a parking space at Cardiff State Beach, Sunday. He and his wife bring their two young sons frequently to enjoy the ocean.

Depending on demand, access during the year could cost from $12 a day to $25 a day during peak summer season at the Cardiff beach.

“Allowing people to come to the beach (for free) and experience the holiday celebrating MLK here in San Diego is a really nice thing,” Megan Northrop said.

These parking meters at Cardiff State Beach will not be required for entry access on Monday, January 18, 2026.

In San Diego County, there are 14 state parks and beaches that will be free on Monday. They include Carlsbad, Silver Strand, and Torrey Pines State Beaches. The State Parks include Cuyamaca Rancho, Palomar Mountain, and Border Field.

Tom Claxton and his wife, Lisa, come to the Cardiff Beach from Escondido so often they invested in an annual parking pass. He enjoys using binoculars, “all I do is scope out for boats and fishing vessels,” he said. His wife enjoys a good book and a cup of coffee while people watching. Both of them agree with the Governor’s action.

“I want everything for free,” Tom said. He joked, “I want everything but don’t want to pay for it. Isn’t that the truth for everybody?”

Amid rising costs, California and L.A. initiatives aim to tax the ultra-rich

Amid rising costs, California and L.A. initiatives aim to tax the ultra-rich


California has billionaires on the brain.

Last week union activists, hoisting giant cutouts of money bags and a cigar-smoking boss, announced a proposal to raise Los Angeles city taxes on companies with “overpaid” chief executives.

They rallied in front of a symbol of the uber rich: the futuristic, steel-covered Tesla Diner owned by Elon Musk, the world’s richest man.

Meanwhile, a “billionaire tax” proposal prompted some of the wealthiest Californians to consider fleeing the state, amid arguments that they would take their tax revenue — and the companies they run — with them, hurting the ordinary residents the proposal is designed to help.

The focus on taxing the richest of the rich comes amid a growing affordability crisis in California, home to the nation’s most expensive housing market and highest income tax.

More than 200 billionaires reside in California, more than any other state, according to a group of law and economics professors at UC Berkeley, UC Davis and the University of Missouri who helped draft the statewide billionaire tax proposal, which proponents are hoping to place on the November ballot.

And they are getting richer. The collective wealth of the state’s billionaires surged from $300 billion in 2011 to $2.2 trillion in October 2025, according to a December report by those professors. In Los Angeles, where the median sale price of $1 million puts home ownership out of reach for many residents, prominent billionaires include David Geffen, Steven Spielberg and Magic Johnson.

One conspicuous billionaire is especially unpopular in California: President Trump, who, despite campaigning on bringing down the cost of living, recently called the word “affordability” a “con job” as he redecorated the White House in gold.

“In a deep blue state like California that has voted against Donald Trump by such large numbers in the last three elections, voters are even more predisposed to be suspicious of billionaires, because he’s now the person with whom they associate the status,” said Dan Schnur, a politics professor at USC, UC Berkeley and Pepperdine.

The state and local tax-the-billionaires proposals, he said, are “about retribution,” much like last year’s Proposition 50, which temporarily redraws the state’s congressional districts to favor Democrats as a counterweight to Trump’s efforts to increase Republican seats in Texas.

To get the statewide billionaire tax proposal on the November ballot, supporters need to collect nearly 875,000 signatures by June 24.

The measure would impose a one-time tax of up to 5% on taxpayers and trusts with assets, such as businesses, art and intellectual property, valued at more than $1 billion. It would apply to billionaires who were residents of the state on Jan. 1, with the option of spreading the tax payment over five years.

Service Employees International Union-United Healthcare Workers West, its main backer, said it will raise $100 billion. Most of those funds would be used for healthcare programs, with the remaining 10% going to food assistance and education programs, the union said.

Suzanne Jimenez, the union’s chief of staff, said Friday that “catastrophic” federal funding cuts stemming from Trump’s One Big Beautiful Bill Act will force hospitals to close, eliminate healthcare jobs and cause insurance premiums to spike, leaving senior citizens and veterans with limited access to services.

The California Budget & Policy Center estimates that as many as 3.4 million Californians could lose Medi-Cal coverage and rural hospitals could close unless a new funding source is found.

Jimenez called the proposal “a modest tax” that “affects few people.”

But Gov. Gavin Newsom vowed to stop the billionaire tax, arguing that California can’t isolate itself from the other 49 states.

“We’re in a competitive environment. People have this simple luxury, particularly people of that status, they already have two or three homes outside the state,” Newsom said at the New York Times’ DealBook Summit last month. “It’s a simple issue. You’ve got to be pragmatic about it.”

The billionaire tax would temporarily increase revenues by tens of billions spread over several years, but if billionaires move away, the state could lose “hundreds of millions of dollars or more per year,” according to the nonpartisan California Legislative Analyst’s Office.

Some of California’s wealthiest say they are indeed heading for the exits.

Andy Fang, the billionaire co-founder of DoorDash, wrote on social media: “I love California. Born and raised there. But stupid wealth tax proposals like this make it irresponsible for me not to plan leaving the state.”

Peter Thiel, the billionaire co-founder of PayPal and Palantir, announced in December that his investment firm opened a new Miami office. He donated $3 million that month to a political action committee connected to the California Business Roundtable, which is fighting the measure.

State records show that Google co-founders Larry Page and Sergey Brin have been cutting ties to California and moving business interests out of state.

Rick Caruso, the billionaire real estate developer who self-funded his losing 2022 L.A. mayoral campaign to the tune of more than $100 million, said in a statement that “the proposed 5% asset tax is a very bad policy. It will deliver nothing it promises and instead hurt California with lost jobs and hundreds of millions a year in lost revenue from existing income taxes.”

Ending months of speculation, Caruso announced Friday he will not challenge Mayor Karen Bass again, nor will he run for governor in a race that includes billionaire hedge fund founder Tom Steyer.

In Los Angeles, supporters of the “Overpaid CEO Tax” announced outside the Tesla Diner that they must collect 140,000 signatures in the next 120 days to get the measure on the November ballot. The measure would raise taxes on companies whose CEOs make at least 50 times more than their median-paid employee. It would apply only to companies with 1,000 or more employees.

The Fair Games Coalition, a collection of labor groups including the Los Angeles teachers union, is sponsoring the measure, which would allocate 70% of the revenue to housing for working families, 20% to street and sidewalk repairs and 5% to after-school programs and access to fresh food.

Business groups have denounced it, saying it would drive companies out of the city.

“Luxury for a few, while those who cook, who clean, who build, who teach, who write — the people who make the city prosperous — are stretched to the breaking point,” Kurt Petersen, co-president of the airport and hotel workers union Unite Here Local 11, said at Musk’s diner, describing it as an avatar for an unjust L.A. economy.

A similar effort to increase taxes on companies with disproportionately paid CEOs is underway in San Francisco, where voters already approved a levy on such businesses in 2020.

On Friday, Doug Herman, a spokesperson for Bass’ reelection campaign, said she has “not taken a position” on the state or city wealth tax proposals. But at her campaign launch last month, Bass framed the mayoral race as “a choice between working people and the billionaire class who treat public office as their next vanity project.”

Jeremy Padawer, a toy industry executive and animated TV producer who lost his home in the Palisades fire, said the mayor’s framing of the race as a battle against billionaires feels contrived, especially given the intense criticism of her handling of the fire.

Power is as relevant as money, and Bass is “the most powerful person in the room,” said Padawer, who organized the “They Let Us Burn” rally on the one-year anniversary of the fire.

“I know a lot of billionaires,” Padawer said. “And I think that billionaires have a propensity to do a lot of good, but they also have the propensity to do a lot of bad.”
