California Sun Podcast

William Riggs is a professor of engineering and management at the University of San Francisco and an expert on transportation innovation. He says San Francisco — now ground zero for America's autonomous vehicle future, with more than 1,000 Waymos on its streets — is exposing a strange contradiction: Society tolerates the deadly carnage caused by human drivers while holding self-driving cars to an impossible standard, even as the data increasingly suggests the technology will save lives.    

Kate Washington spent years giving everything to everyone else — caregiving, motherhood, a failing marriage — until she was empty. Her answer was cold water: 50 dunks in California rivers, creeks, and swimming holes before her 50th birthday. The author of "Midstream: A Life Remade in 50 Swims," she shares her story about joy and water as an act of reclamation.

Dillon Osleger has spent a decade rebuilding what America has been quietly erasing — the trails, wagon roads, and Indigenous paths that once knitted California and the West together. As a geologist, trail builder, and public lands advocate, he brings both scientific precision and moral urgency to the cause. His new book, "Trail Work," makes the case that losing these paths means losing ourselves.

Julia Turner and Julia Wick have spent their careers covering Los Angeles — and like anyone who's lived here long enough, they couldn't always figure it out either. So they did what journalists do. They started digging. L.A. Material is their newly launched independent digital newsroom, and their obsession is simple: making sense of a city that resists it.

Peter Richardson, author of the new book "Brand New Beat: The Wild Rise of Rolling Stone Magazine," discusses the pioneering music magazine's San Francisco decade — between 1967 and 1977 — when the Bay Area's counterculture reshaped music and the journalism that covered it. From Haight-Ashbury to the Fillmore, Hunter S. Thompson to Annie Leibovitz, the magazine documented a social revolution while simultaneously creating it.

Ann Carlson discusses her new book "Smog and Sunshine: The Surprising Story of How Los Angeles Cleaned Up Its Air." Smog was once as much a symbol of L.A. as palm trees — a bane to public health and a national punchline on Johnny Carson's "Tonight Show." An expert in environmental law, Carlson chronicles the decades-long battle that transformed the air from toxic to breathable, and what today's rollbacks threaten to undo.

Severin Borenstein, a professor at UC Berkeley's Haas School of Business and an expert on the economics of energy, explains how the Iran war is disrupting global oil markets and why California faces especially sharp price impacts. Beyond the crude oil disruptions affecting everyone, the state's refinery shutdowns, import constraints, and gasoline surcharge create unique vulnerabilities as supply chains scramble to adjust.

Miriam Pawel, author of the definitive Cesar Chavez biography, "The Crusades of Cesar Chavez," reflects on the recent shattering of the Cesar Chavez myth — and the harder questions beneath it: what was known, what was ignored, and why movements so often need saints. In this wide-ranging conversation, Pawel explores Chavez's charisma, control, contradictions, and the challenge of holding both his historic achievements and the harm he may have caused in the same frame.

Caroline Tracey explores the world's threatened salt lakes with a focus on California — Mono Lake, Owens Lake, and the Salton Sea — where irrigation diversions have transformed stunning desert ecosystems into sources of toxic dust. She discusses landmark environmental cases that established California's public trust doctrine and how these seemingly dead landscapes remain vital habitats worth preserving. Her decade of research across four continents is chronicled in her new book "Salt Lakes: An Unnatural History."

Joe Flint, a media reporter for the Wall Street Journal, joins us as Hollywood heads into Oscar weekend — a moment when the world celebrates the glamour of the movies even as the business faces deep uncertainty. Flint looks at the industry's economic upheaval: mergers, mounting debt, streaming disruption, and the growing question of whether the Hollywood model that built California's cultural and economic identity can survive the digital age.

Chef Geoff Davis opened Burdell in Oakland to cook the soul food his grandmothers made — a distinct American cuisine rooted in migration and adaptation rather than Southern tradition. In 2024, Food & Wine named it the "Restaurant of the Year." But it was a 20% service fee at the bottom of Burdell's receipts that recently started a national conversation about labor, class, and whether we've ever really reckoned with the history of tipping.

Valerie Ziegler, a high school teacher in San Francisco, and Joel Breakstone, executive director of Stanford's Digital Inquiry Group, talk about digital literacy in the classroom. Many self-described "screenagers," they say, can no longer tell real from fake. Together, Ziegler and Breakstone are at the forefront of a movement to prepare young people for a world of influencers, algorithmic manipulation, and artificial intelligence, an effort recently profiled in the New York Times.

When California legalized recreational cannabis, Silicon Valley envisioned a new Gold Rush. Tushar Atre — a tech entrepreneur, surfer, and disruptor — thought he could bridge two worlds: venture capital and the black market. On Oct. 1, 2019, he was shot execution-style on his own property, hands bound. Investigative journalist Scott Eden, author of the new book "A Killing in Cannabis," spent four years unraveling what happens when ambition meets an industry that never forgot its outlaw roots. 

Danny Goldberg, author of the new book "Liberals with Attitude: The Rodney King Beating and the Fight for the Soul of Los Angeles," was there in 1991 when an unlikely Los Angeles coalition fought to hold the city's police department accountable for the beating of Rodney King. Thirty-four years later, after George Floyd and the recent events in Minneapolis, Goldberg wonders whether the sort of cross-ideological cooperation that happened in the 1990s is still possible today.

David McCuan, a professor of political science at Sonoma State University, discusses the findings of a recent Los Angeles Times exposé that showed how California's beloved county fairs, which generate $400 million annually, have become hotbeds of corruption where bookkeepers steal, officials rig bids, and governor-appointed boards feast on lobster and cabernet. With governance structures frozen since the 1880s and no state audits for years, one-third of these fairs are now plagued by fraud — even as they've become critical staging grounds for disaster response worth tens of millions in real estate.

The Los Angeles-based artist Laurie Lipton shares why she's drawn obsessively since age four, how she invented her "insane" cross-hatching technique studying Dutch Masters in Europe, and how waitressing paid the rent so she could draw. After 36 years abroad, she says she returned to Los Angeles to find America rolled back to 1955. She discusses why drawing is her drug, how stepping aside lets the work flow, and why political art struggles to find gallery walls.

Esther Mobley, a wine critic for the San Francisco Chronicle, talks about California's wine industry crisis — nearly 5,000 wineries competing for declining demand, 38,000 vineyard acres removed in 2025, mounting closures. She discusses why younger generations aren't drinking wine, what happens to tourism-dependent communities when vineyards close, and whether California wine's romance can survive its greatest challenge yet.

Last week, MTV officially shut down, ending an era that revolutionized music, video, and shaped California's youth culture. Tom Freston co-founded the television channel 44 years ago, building a creative empire on principles that seem impossible today: hiring people with no experience, protecting creatives from corporate pressure, valuing disorientation over data, and treating loyalty as strategy. His memoir "Unplugged" chronicles how adventure became business,  and what we lost when Silicon Valley replaced joy with efficiency.

Scot Danforth, author of the new biography "An Independent Man," talks about the life of Ed Roberts, who founded the Independent Living Movement. In the revolutionary 1960s, Roberts and his fellow Berkeley activists pioneered the disability rights fight. He later led change in Sacramento as California's Director of Rehabilitation, advocating for state legislation years before the federal Americans with Disabilities Act. But, as current threats show, hard-won gains like these can be taken away.

Photographer Matthew Scott captures Los Angeles through his lens, revealing stories hidden in plain sight. His projects include "Concrete River," an ongoing exploration of the 51 miles of channelized waterway where nature stubbornly persists, along with intimate studies of L.A.'s palm trees and Normandie Avenue. His work asks what our built environment becomes beyond its intended purpose, and what it reveals about who we are. Find his work at MathewScott.com.

Gustavo Arellano reports from California's ground zero of President Trump's deportation crackdown. The Los Angeles Times columnist explains why many Latino voters who supported Trump now feel betrayed, how Southern California's "suburban apathy" toward immigration raids contrasts with Chicago's whistle-led resistance, and how the dynamics of 1994's the anti-immigrant Proposition 187 — which radicalized a generation of California Latinos — have echoed in current debates over immigration.

Roddy Bottum, a founder of the alternative metal band Faith No More, chronicles 1980s and '90s San Francisco — a dark, overlooked era between the Summer of Love and the tech boom. His memoir, "The Royal We" recalls a vanished city of bicycle messengers and punk rock in the shadow of the AIDS crisis. It's a poetic testament to community, loss, and the creative rebellion that defined pre-tech San Francisco.

Ashlee Vance reports from San Francisco's underground robot fight clubs, where humanoid machines controlled by virtual reality pilots battle in steel cages before roaring crowds. China dominates the hardware, America provides the spectacle, and artificial intelligence makes the robots increasingly lethal. The technology is advancing at breakneck speed — raising questions about entertainment, military applications, and what happens when these machines become truly intelligent.

Todd S. Purdum, veteran journalist and author of the new book "Desi Arnaz: The Man Who Invented Television," explains how a Cuban refugee revolutionized Hollywood from his adopted home in Los Angeles. Though underappreciated as a showbiz entrepreneur, Arnaz pioneered the three-camera sitcom format, shifted television production from New York to Los Angeles, and created the business model that would sustain the industry and TV production for seven decades.

John Freeman, author of "California Rewritten: A Journey Through the Golden State's New Literature," talks about how California has become America's new literary center, challenging New York's dominance. He discusses the pandemic book club that sparked his journey, the state's evolving mythology, and how diverse voices are redefining what it means to imagine America's future.

Filmmaker Ari Gold turns the camera on his own family in "Brother Verses Brother," an ambitious one-shot musical that follows him and his identical twin brother searching for meaning through the streets of San Francisco's North Beach, alongside their 99-year-old novelist father, Herb. Gold explains how this experimental work, executive produced by Francis Ford Coppola and generating serious buzz on the festival circuit, blurs the line between documentary and fiction, asking uncomfortable questions about art, family, and what we're willing to expose in pursuit of truth.

Dina Gilio-Whitaker, author of the new book "Who Gets to Be Indian?" explores how California became ground zero for Native American identity fraud — from Hollywood's early film lots to today's casino capitalism and tribal disenrollment crisis. The state's confluence of entertainment industry, counterculture movements, federal relocation programs, and gaming wealth created perfect conditions for "Indianness" to become commodified, challenging authentic tribal sovereignty and belonging across the nation.

Mike Magee is the president of Minerva University, which has earned the No. 1 ranking in the World University Rankings for Innovation for four consecutive years. Founded in San Francisco in 2012, Minerva reimagined higher education — eliminating campuses, lectures, and tenure while sending students to live and study across seven global cities. Magee discusses how Minerva, with only a 4% acceptance rate and students from more than 100 countries, is preparing the next generation of leaders for an interconnected world.

Tim Higgins discusses his new book "iWar," examining how one of California's corporate crown jewels, Apple, faces an unprecedented rebellion. Tech leaders such as Spotify's Daniel Ek and Epic's Tim Sweeney are waging a legal war over what they have portrayed as a shakedown operation — the 30% App Store cut that generates massive profits for Apple while stifling competition. As this battle imperils Apple's hold on the mobile world, the rise of artificial intelligence is threatening to potentially displace the smartphone era altogether.

Jeff Chang, in his new biography "Water Mirror Echo," explores how the short of life of Bruce Lee helped make Asian America. Born in San Francisco's Chinatown, Lee was denied the lead role in Warner Bros.'s 1970s TV series "Kung Fu," which was given instead to David Carradine in yellowface. Lee's collision with Hollywood rejection became a catalyst for his rise at a time of emergent Asian American political consciousness. Chang discusses how Lee became a global symbol of Asian American dignity, and how his legend has only grown in the decades since his death.

Satsuki Ina was born behind barbed wire at Tule Lake, where she became one of roughly 120,000 Japanese Americans incarcerated during World War II. Her parents, both U.S. citizens, lost their freedom and faith in America, leaving a legacy of silence and trauma. Today, as immigrant families are again separated and detained, Ina's memoir "The Poet and the Silk Girl" chronicles her family's journey through California's network of assembly centers and permanent camps. It's a reminder, she says, that what happened then is not just history — it's a warning about how easily such chapters of fear and racism repeat themselves.

Peter Jones turned his camera on his former classmates from the Harvard School for Boys, a former military academy for boys in Los Angeles, for his new documentary "Fortunate Sons," chronicling the lives of the 1974 graduating class through their 50th reunion. What started as pandemic Zoom calls became surprisingly honest conversations about addiction, suicide, and the pressure of living up to successful fathers. Jones discovered that wealth can't shield against every hardship, and that the men now in their 60s were finally ready to drop the macho act and talk about what really happened.

Eve Quesnel, author of  the new book "Snow Fleas and Chickadees: Everyday Observations in the Sierra," joins us from her home in Truckee. For more than two decades, she's been paying close attention to the Sierra Nevada, finding evidence that "nature will show up" everywhere — even in urban cracks and sidewalks. Quesnel discusses making a conscious effort to step outside our digital distractions, the importance of knowing your neighborhood ecosystem, and how simple daily walks can transform our understanding of the natural world around us.

Jim Newton joins us to discuss his new book "Here Beside the Rising Tide," exploring how Jerry Garcia and the Grateful Dead emerged from 1960s California to become unlikely architects of America's counterculture. Newton reveals Garcia as a reluctant icon who feared leadership yet created a multigenerational community that thrives decades after his death. We explore the Dead's anti-commercial ethos, their role as cultural catalysts rather than political activists, and how their California values of freedom and authenticity continue to influence everything from music to tech culture.

Sam Yebri, a young Yale-educated labor attorney and board president of the civic organization Thrive LA, offers a stark assessment of Los Angeles's decline. Yerbi arrived as a refugee from Iran to L.A., where he has embodied the American dream in a city that has served as a beacon for immigrants and dreamers. But he paints a not-so hopeful picture of crime, homelessness, and corruption overwhelming the city. Yebri believes change is possible but requires new leadership and greater civic engagement.

Matt Ritter, a botany professor at Cal Poly San Luis Obispo, and Michael Kauffmann, a research plant ecologist, have written a new definitive guide to California's 95 native tree species, "California Trees." The authors discuss their field work across the state, from the rare conifers of the Klamath Mountains to the Joshua trees of the Southern California desert. They reveal how citizen science and new mapping techniques are documenting biodiversity hotspots, and how climate change and wildfires are rapidly reshaping California's forests.

Gene Seroka, executive director of the Port of Los Angeles, oversees a gateway that handles 20% of America's incoming cargo and powers one in nine jobs in Southern California. In this conversation, he reveals how the 7,500-acre complex serves as an economic bellwether, highlighting trends months before consumers feel them. From automation debates to tariff-induced cargo swings, Seroka explains how what happens at the port ripples through California's economy and shapes global trade.

Christopher Beam, in a recent New York Times investigation, reveals how a group of brilliant minds from Google, NASA, and the rationalist movement in Berkeley became part of a murderous cult-like group known as the "Zizians." He story recounts six deaths, from a blood-soaked Vallejo property to a fatal Vermont shootout. Unlike Charles Manson's dropouts, these tech elites weaponized artificial intelligence fears and rational thinking into deadly extremism, which was enabled by California's tolerance for radical ideas.

Beverly Hills Mayor Sharona Nazarian fled Iran with her family during the revolution to escape religious persecution, learning English as her third language before building a career in clinical psychology. Now the first Iranian American woman to lead the city, she governs a diverse community where roughly 20% of the population trace its roots to Iran. As war unfolds in the Middle East, she's tells us how she's become the de facto voice of a diaspora caught between American dreams and a longing for peace in their homeland.

Josh Jackson, author of the new book "The Enduring Wild," found a hidden refuge in the mountains and prairies of California's 15 million acres of Bureau of Land Management lands. In times of crisis and uncertainty, we often turn to nature for solace and perspective. These overlooked "commons," dismissed as leftover lands too harsh for homesteaders and too ordinary for national parks, offer free camping, wildlife corridors, and democratic access to wilderness. They now face threats from proposed selloffs and budget cuts.

Gustavo Arellano, the longtime Los Angeles Times columnist and chronicler of the Latino community, brings his deeply personal perspective to the immigration crackdown unfolding in Los Angeles. He shares observations from the epicenter of protests that have drawn President Trump's National Guard deployment. Born to a Mexican father who snuck across the border as a teenager, Arellano's voice carries both the weight of historical context and the urgency of someone who sees his community under siege.

Michael Hiltzik, the author of "Golden State: The Making of California," examines five centuries from the Spanish conquistadors to Silicon Valley, challenging the enduring mythology that has shaped both California and America. Rather than offer another celebration of the California dream, Hiltzik reveals how the state has served as America's testing ground — where national ideals about opportunity, innovation, and reinvention were both realized and betrayed. The state's true history, he argues, provides essential insights into America's character and future.

Eleni Gastis, the journalism department chair at Oakland's Laney College, was shocked to discover that half her students weren't human. California's community colleges are under siege by sophisticated "ghost students" — bots designed to steal financial aid money. What started as a $3 million-a-year problem exploded to $13 million over the last 12 months, with fraudsters exploiting system vulnerabilities. Gastis is now leading the fight for transparency while teaching the next generation of journalists to navigate truth in an age of digital deception.

Matthew Specktor, in his new memoir "The Golden Hour," offers a unique perspective on Hollywood's transformation — as both the son of legendary talent agent Fred Specktor and a thoughtful cultural observer. He explores how the movie industry shifted from a close-knit "family business," where art and commerce balanced, to today's corporate-dominated landscape. Specktor reflects on how this mirrors broader American cultural changes, the diminishing role of movies in our collective imagination, and what's lost when filmmaking becomes primarily about algorithms and franchises rather than human stories.

Adam Nagourney, a veteran New York Times reporter based in Los Angeles, wrote recently about whether the California Dream had become a mirage. Even as the state has grown into the world's fourth-largest economy, the promise of reinvention that defined the Golden State feels increasingly elusive. As young people flee, wildfires destroy neighborhoods, and a hostile White House turns its back, Nagourney believes California is still resilient and capable of that dream. 

Joe Kloc spent nine years immersed with Richardson Bay's "anchor-outs," a community living on abandoned vessels just offshore from multimillion-dollar Sausalito homes. In his book "Lost at Sea," Kloc chronicles their struggles against the authorities and residents who ultimately dismantled the century-old floating community. Kloc captures the anchor-outs' resilience amid displacement, exploring what happens when society pushes its most vulnerable members to the margins.

Laurie Kirby, the founder of FestForums, brings insider expertise on what makes music festivals succeed. She explores California's vibrant festival scene from Coachella and Stagecoach to BottleRock and Outside Lands, examining how these events reflect the state's economic trends and cultural influence. She discusses how California's festivals function as economic indicators of changing consumer habits and whether the state's market has reached saturation.

Ben Fritz, who covers the entertainment industry for The Wall Street Journal, explores Hollywood's perfect storm of existential threats — empty theaters, streaming wars, production flight, artificial intelligence. If that wasn't enough, as Fritz has reported: audiences today seem to be rejecting both franchise tentpoles and original films. He discusses whether Hollywood can reinvent itself as it has done in the past and adapt to technological change while maintaining its global cultural influence and economic importance to California.

Erica Hellerstein's reporting for El Tímpano follows the story of Pedro Romero Perez, a survivor of the 2023 Half Moon Bay mass shooting that left seven people dead, including his brother Jose. The tragedy exposed deplorable conditions in San Mateo County's agricultural industry: farm workers earning less than minimum wage while living in shipping containers without running water. Perez, who survived five gunshot wounds, emerged as an unexpected voice for change through a lawsuit against his former employer.
