California “snow deluges” expected to decline significantly by 2100

Extreme snowfall will become less common in California by 2100, a new study found.

Scientists understand how a lack of snow or “snow drought” can affect a region, especially in the midst of a warming climate. However, before now, they did not understand the impact of unusually high levels of snow. And this is becoming more important, as California has just emerged from its second winter of high snowfall.

A new study published in the Proceedings of the National Academy of Sciences used the 2023 winter as a case study to learn more. Computational hydrologist Adrienne Marshall and colleagues from the Colorado School of Mines dubbed the term “snow deluges” to describe the phenomenon recently seen in California.

To reach their findings, they analyzed the unusual snow deluge across the Sierra Nevada mountains in 2023 to assess the impact of “high snow years.”

In 2023, California saw an extremely high amount of snow accumulation, with record snowpack levels. Observations showed the accumulations were a “once-in-54-years event,” with some areas reporting “once-in-320-years accumulations,” the study reported.

By looking at climate projections, scientists found that years like these with the so-called “snow deluges” are set to decline by 58 percent by the end of this century. Years with median levels of snowfall are also estimated to decline by 73 percent, they reported.

“California’s massive snow year of 2023 was record-breaking at 42 percent of snow monitoring sites,” Marshall told Newsweek. “Climate models indicate that in warmer future climates, our biggest snow years will be smaller than our biggest snow years now. Another way of putting this is that a snow deluge like we saw in 2023 would be much more rare in a warmer climate like that we might expect later in the 21st century.”

Similar patterns will also be seen across the wider Western U.S., the study reports.

The findings “underscore the significance of uncovering the impact of climate change on the dynamics of snow deluges and snow droughts in mountainous regions,” the study reports.

“These findings align with a bigger scientific picture that shows declining average snowpack and more frequent snow droughts in California and throughout the West,” Marshall said. “Our new findings suggest that we shouldn’t count on big snow years like the one we had last year to save us in warmer climates.

“This is important because snow acts as a natural reservoir in the mountains that stores water until the late spring and summer when we need it most. Our best opportunities to avoid the worst consequences of this snow loss lie in reducing our greenhouse gas emissions and finding ways to adapt to adapt to changing snow and water availability.”

The study notes that snow deluges can be “both destructive and beneficial” meaning better understanding of the phenomenon can improve management of “snow-dependent ecosystems and economies.”

The 2023 snow deluge in California, in many ways, could be seen as good thing. Before it occurred, the state had been suffering from prolonged drought conditions. As a result, there was a severe lack of snowpack in the surrounding mountains, meaning less water was feeding the state’s reservoirs.

The large snow build-up, however, meant that come spring, it melted into rivers and reservoirs, saving the state from a water crisis. In fact, drought conditions in the state officially ended.

However, the heavy snowfall indicates that climate change is worsening, as weather patterns become more unpredictable and extreme. While the drought has ended for now, climate change could cause another prolonged dry period in the future.

“Snow is important for both ecosystems and water resources, and there’s a lot still to learn about how our biggest snow years—or the loss of them—impact these systems,” Marshall said. “The present study focuses on annual-scale snow deluges, but the largest individual snowfall events could change in different ways.

“We focused on a moderate warming scenario in California and the Western U.S., but it would also be helpful to learn more about how different climate scenarios could affect snow deluges in other parts of the world.”

PlayOn Sports fined $1.1 million by California watchdog over student data violations

PlayOn Sports fined .1 million by California watchdog over student data violations

SACRAMENTO, Calif. (FOX26) — California’s privacy watchdog has ordered PlayOn Sports to pay a $1.10 million fine and change how it handles consumer data after finding the company’s practices violated state law in ways that affected students and schools in the state.

The California Privacy Protection Agency Board issued the decision following a settlement reached by CalPrivacy’s Enforcement Division.

The decision is the first by the board to address privacy violations involving students and California schools.

Schools across the country use PlayOn Sports’ GoFan platform to sell digital tickets to high school sporting events, theater performances, and homecoming and prom dances, with attendees presenting tickets at the door on their mobile phones.

Schools also use PlayOn Sports’ platforms for other sports-related activities, including attending games, streaming them online, and looking up statistics about teams and players.

In California, about 1,400 schools contract with PlayOn Sports for these services.

GoFan is also the official ticketing platform for the California Interscholastic Federation, the governing body for high school sports.

According to the board’s decision, PlayOn Sports used tracking technologies to collect personal information and deliver targeted advertisements to ticketholders and others using its services.

The company allegedly required Californians to click “agree” to tracking technologies before they could use their tickets or view PlayOn Sports websites, without providing a sufficient opt-out option.

“Students trying to go to prom or a high school football game shouldn’t have to leave their privacy rights at the door,” said Michael Macko, CalPrivacy’s head of enforcement. “You couldn’t attend these events without showing your ticket, and you couldn’t show your ticket without being tracked for advertising. California’s privacy law does not work that way. Businesses must ensure they offer lawful ways for Californians to opt-out, particularly with captive audiences.”

The decision also describes students as a uniquely vulnerable population and warns that targeted advertising systems can subject students to profiling that can follow them for years, expose them to manipulative or harmful content, and develop sensitive inferences about their lives.

Instead of providing its own opt-out method, PlayOn Sports directed students and other users to opt out through the Network Advertising Initiative and the Digital Advertising Alliance, which the decision said violated the company’s responsibility to provide its own way for consumers to opt out. The company also allegedly failed to recognize opt-out preference signals and did not provide Californians with sufficient notice of its privacy practices.

“We are committed to making it as easy as possible for all Californians — from high school students to older adults, and everyone in between — to make the choice of whether they want to be tracked or not,” said Tom Kemp, CalPrivacy’s executive director. “Californians can opt-out with covered businesses, and they can sign up for the newly launched DROP system to request that data brokers delete their personal information.”

Beyond the $1.10 million fine, the board’s order requires PlayOn Sports to conduct risk assessments, provide disclosures that are easy to read and understand, and implement proper opt-out methods.

The order also requires the company to comply with California’s privacy law prohibiting the selling or sharing of personal information of consumers between 13 and 16 without their affirmative opt-in consent.

CA bill to keep police from moonlighting with ICE advances

SACRAMENTO, Calif. (KABC) — A bill that would prevent police officers from moonlighting with federal immigration enforcement agencies, such as U.S. Immigration and Customs Enforcement, is advancing through the California State Assembly.

AB 1537 passed the State Assembly’s committee on public safety on Tuesday.

The bill also requires that officers report any offers for secondary employment related to immigration enforcement to their place of work.

Those failing to comply could face decertification as a peace officer in California.

The bill was introduced by Assemblymember Isaac Bryan, whose district includes Mar Vista, Ladera Heights, Mid-Wilshire and parts of South Los Angeles.

Can’t win in primary election? Drop out, California Democrats say

Can’t win in primary election? Drop out, California Democrats say

California Democrats running for governor, your party has a message for you. Think carefully about your candidacy and campaign ahead of the swiftly approaching filing deadline.

California Democratic Party Chair Rusty Hicks urged candidates looking to assume the state’s highest office to “honestly assess the viability of their candidacy and campaign” as March 6, the final day to declare candidacy, nears. Hicks said that concerns about the crowded field of Democrat candidates “persist” in an open letter on Tuesday, March 3.

It comes as five leading candidates, several of which are Democrats — Katie Porter, Eric Swalwell, and Tom Steyer — are in a “virtual tie” per a recent poll, the Desert Sun reported, which is part of the USA TODAY Network.

Two Republican candidates pushing out California democrats in the gubernatorial bid may be “implausible,” but “it is not impossible,” Hicks said of the reasoning behind his latest message. Steve Hilton and Riverside County Sheriff Chad Bianco, both Republicans, lead in RealClear Polling’s average of various polls.

The party chair spotlighted the need for California Democrats’ leadership, particularly over Proposition 50, the voter-approved measure that will temporarily implement new congressional district maps, paving the way for Democrats to secure more seats in the U.S. House of Representatives.

“If in the unlikely event a Democrat failed to proceed to the general election for governor, there could be the potential for depressed Democratic turnout in California in November,” Hicks said. “The result would present a real risk to winning the congressional seats required and imperil Democrats’ chances to retake the House, cut Donald Trump’s term in half, and spare our nation from the pain many have endured since January 2025.”

During a press conference on March 2, Gov. Gavin Newsom said that when he is out in communities, people aren’t talking about the governor’s race. It’s an observation he called “interesting,” considering voting in the primary election starts in May.

“It’s been hard, I think, to focus on that race,” Newsom said, pointing to the attention on President Donald Trump, redistricting, and other matters.

What exactly is California Democratic Party asking of candidates?

In his open letter, Hicks gave directions to candidates.

First, assess your candidacy and campaign. If you don’t have a viable path to the general election, don’t file to get your name on the ballot for the primary election in June. Also, be prepared to suspend your campaign and endorse another candidate by April 15 if you decide to file but can’t show “meaningful progress towards winning the primary election.”

When is the next California election? Primary election in 2026

California voters will trim the field of candidates for governor on June 2. Only the two candidates who receive the most votes, regardless of party preference, will move on to the November election.
