Upwelling, the Ocean’s Engine Beneath California’s Waters

Would you support us? Just a few bucks. We’d appreciate it!

I recently revisited a book I enjoyed: The Blue Machine by physicist, oceanographer, and writer Helen Czerski. It is a beautifully clear exploration of the deep mechanics of the ocean and why those processes are so essential to keeping our planet cool, biodiverse, and stable.

One of the core ideas she returns to is ocean upwelling, a process that is especially important for those of us who live in California. Upwelling is one of those hidden forces that quietly underlies everything around us, and once you read about it, you realize that so much of what we know and love here simply would not exist without it.

Few marine processes are as impactful on the abundance of sea life off the coast of California as upwelling. It may not be a term you’ve heard before, but the natural oceanic process of upwelling is one of the most important engines driving climate, biological diversity, and the ocean’s food web.

It’s time to pay attention.

In simple terms, upwelling is when cold, nutrient-rich water from the deep ocean rises to the surface, replacing warmer surface water. A churn. Along the California coast, prevailing northerly winds push surface waters offshore through the Coriolis effect, allowing deeper, colder water to rise in their place. Over the continental shelf off shore California, this upwelled water is rapidly brought into shallower depths, delivering nutrients directly into the photic zone where phytoplankton can grow. This is one reason continental shelves, including areas around offshore oil platforms (which I wrote about a few weeks ago), are biological hotspots.

California’s upwelling system is one of the most intensively studied in the world because it fuels the region’s crazy marine productivity.

In California, upwelling occurs year-round off the northern and central coast. It’s strongest in the spring and summer when northwesterly winds are at their most powerful. Upwelling is reduced in the fall and winter when winds are more variable.

Researchers from institutions like the Scripps Institution of Oceanography and Stanford University have used a variety of methods, including satellite observations and computer modeling, to study upwelling. One of the groundbreaking studies was the CalCOFI program (California Cooperative Oceanic Fisheries Investigations), which began in the late 1940s. It was a joint venture between Scripps and state and federal agencies to investigate the collapse of the sardine fishery. The study showed that the sardine collapse was not just due to overfishing but also large-scale ocean and climate variability, a finding that reshaped fisheries science. Over decades, it has expanded its scope and now provides invaluable long-term datasets that help scientists understand upwelling and its impacts on marine populations.

Deep, cold ocean water is rich in nutrients because organic matter from the surface sinks as it dies or is consumed, and is broken down at depth, releasing nutrients back into the water. When that water is brought to the surface through upwelling, it delivers a fresh supply of nutrients that fuels phytoplankton growth and supports the entire marine food web.

The food web is kind of like a ladder. Or a chain. Nutrient-rich cold waters support blooms of phytoplankton: microscopic, photosynthetic organisms (meaning they are teeming with chlorophyll) that produce oxygen and form the base of marine food webs. When these primary producers flourish, it triggers a chain reaction throughout the ecosystem: zooplankton feed on phytoplankton, small fish feed on zooplankton, and larger predators, including fish, marine mammals, seabirds, (and humans) reap the rewards! So a well functioning upwelling system is pretty important for abundant sea life.

Also, cold water holds more dissolved gases like oxygen compared to warm water (yet another reason that warming seas could be a problem in the future). Oxygen is crucial for marine animals. In cold, oxygen-rich environments, organisms can efficiently carry out metabolic processes, which leads to higher rates of feeding, growth, and reproduction, thereby further boosting biological productivity. Everyone wins!

But there’s a problem.

Studies have shown that natural changes in climate, like El Niño and La Niña events have a significant impact on wildlife and the local ocean ecosystem. During El Niño events, warmer waters and weaker upwelling reduce nutrient levels in the California Current, lowering phytoplankton productivity and causing deadly ripples through the food web. La Niña conditions generally strengthen upwelling, bringing nutrient-rich water to the surface and boosting marine productivity.

Climate change adds a potentially dangerous new layer of uncertainty: oceans are warming and growing more acidic, which can disrupt the timing, strength, and benefits of upwelling. While climate change does not necessarily mean more El Niño years, it does mean that El Niño events now play out in a warmer ocean, often amplifying their impacts and increasing stress on marine life, with serious consequences for some organisms.

We’ve been seeing some of these impacts. Take sea lions and large fish populations. In years of strong upwelling, prey is more abundant and closer to shore, allowing California sea lions to forage more efficiently and increasing populations. During weak upwelling years, prey becomes scarcer and more dispersed, forcing sea lions to travel farther for food, increasing stress and reducing reproductive success. Variations like this have been observed in recent years during El Niño periods along the California coast, showing how quickly marine ecosystems respond to shifts in ocean conditions.

Of course, upwelling isn’t just a California thing; it’s a global phenomenon that occurs in various parts of the world, from the coasts of Peru to the Canary Islands. It serves a similar churning life inducing function in these places, too. But California is sort of the poster child for scientists thanks to extensive research here and its vital role in a multi-billion dollar fishing industry that includes species like albacore tuna, swordfish, Dungeness crab, squid, and sardines.

Upwelling is one of those critical oceanic processes that helps maintain our stable and immensely productive California waters, but warming ocean temperatures and changes in wind patterns could cause big problems, disrupting the timing and intensity of upwelling, putting sea life off California’s coast at risk.

Of course, I do not mean for this piece to be yet another downer about climate change. California’s coastal ecosystem is, in many ways, healthier today than it has been in decades, thanks to policies and practices put in place once we began to understand what was truly at stake. Whenever I get offshore and experience the ocean firsthand, I feel deeply grateful for what we have now, even as I remain aware that it is something we could still damage if we’re stupid and careless…which is not out of the question. The encouraging part is that Californians have shown, again and again, a real capacity to rally when it matters. For now, then, it is worth appreciating what we have and getting out there to experience it whenever you get the chance.

The Happy Nut: California’s Rise to Pistachio Power

Pistachios grow on a tree in the Central Valley (Photo: Erik Olsen)
Would you support us? Just buck or two. We’d appreciate it!

I just got back from a filming assignment in California’s Central Valley. That drive up I-5 and Highway 99 is always a strange kind of pleasure. After climbing over the Grapevine, the landscape suddenly flattens and opens into a vast plain where farmland and dry earth stretch endlessly in every direction. A pumpjack. A dairy farm. Bakersfield. There’s a mysterious, almost bleak beauty to it. Then come the long stretches where the view shifts from dust to trees: pistachio trees. Especially through the San Joaquin Valley, miles of low, gray-green orchards extend to the horizon. At various points, I busted out a drone and took a look, and as far as I could see, it was pistachio trees. A colorful cluster of pistachios hung from a branch and I picked on and peeled off the fruity outer layer. There was that familiar nut with the curved cracked opening. The smiling nut.

California now grows more pistachios than any place on Earth, generating nearly $3 billion in economic value in the state. Nearly every nut sold in the United States, and most shipped abroad, comes from orchards in the Central Valley. The state produces about 99 percent of America’s pistachios, and the U.S. itself accounts for roughly two-thirds of the global supply. And that all happened relatively quickly.

When the U.S. Department of Agriculture began searching for crops suited to the arid West in the early 1900s, the pistachio was an obvious choice. In 1929, a USDA plant explorer named William E. Whitehouse traveled through Persia collecting seeds. Most failed to germinate, but one, gathered near the city of Kerman, produced trees that thrived in California’s dry heat. The resulting Kerman cultivar, paired with a compatible male variety named Peters, became the foundation of the modern industry. Every commercial orchard in California today descends from those early seeds.

For decades, pistachios were sold mainly to immigrants from the Middle East and Mediterranean. It wasn’t until the 1970s that California growers, backed by UC Davis researchers and improved irrigation, began planting on a large scale. By the early 1980s, they had found their perfect home in the southern San Joaquin Valley—Kern, Tulare, Kings, Fresno, and Madera Counties—a region with crazy hot summers, crisp winters…according to researchers, the kind of stress the trees need to flourish.

Then came The Wonderful Company, founded in 1979 by Los Angeles billionaires Stewart and Lynda Resnick. From a handful of orchards, they built an empire of more than 125,000 acres, anchored by a vast processing plant in Lost Hills. Their bright-green “Wonderful Pistachios” bags and silly “Get Crackin’” ads turned what was once an exotic import into a billion-dollar staple.

But the company’s success is riddled with controversy. Mark Arax wrote a scathing piece a few years ago about the Resnicks in the (now, sadly defunct) California Sunday Magazine. The Resnicks have been criticized for their immense control over California’s water and agriculture, using their political influence and vast network of wells to secure resources that many see as public goods. Arax described how the couple transformed the arid west side of the San Joaquin Valley into a private agricultural empire, while smaller farmers struggled through droughts and groundwater depletion. “Most everything that can be touched in this corner of California belongs to Wonderful,” Arax writes. (Side note: Arax’s The Dreamt Land made our recent Ten Essential Books About California’s Nature, Science, and Sense of Place.)

And yes, pistachios have been immensely profitable for the Resnicks. Arax write: “All told, 36 men operating six machines will harvest the orchard in six days. Each tree produces 38 pounds of nuts. Typically, each pound sells wholesale for $4.25. The math works out to $162 a tree. The pistachio trees in Wonderful number 6 million. That’s a billion-dollar crop.”

Alas, California’s pistachio boom carries contradictions. The crop is both water-hungry and drought-tolerant, a paradox in a state defined by water scarcity. Each pound of nuts requires around 1,400 gallons of water, less than almonds, but still a heavy draw from aquifers and canals. Pistachio trees can survive in poor, salty soils and endure dry years better than most crops, yet once established, they can’t be left unwatered without risking long-term damage. Growers call them a “forever crop.” Plant one, and you’re committed for decades.

The pistachio has reshaped the Central Valley’s landscape. Once a patchwork of row crops and grazing land, vast acres are now covered in pistachio orchards, the ones I was recently driving through.

Pretty much everyone growing anything in California – pistachios, almonds, strawberries (especially strawberries) – can thank the University of California at Davis for help in improving their crops and managing problems like climate change and pests. Davis is a HUGE agricultural school and has many programs to help California farmers.

UC Davis is one of the world’s leading research centers for nuts, especially pistachios, almonds, and walnuts. Scientists here study everything from drought-tolerant rootstocks to disease resistance and pollination, making it the quiet engine behind California’s multibillion-dollar nut industry. (Photo: Erik Olsen)

In the case of the pistachio, recent research at UC Davis has shed new light on the tree’s genetic makeup. Scientists there recently completed a detailed DNA map of the Kerman variety, unlocking the genetic controls of kernel size, flavor compounds, shell-splitting behaviour and climate resilience. The idea is to help growers by making pistachios adapt to hotter, drier conditions. UC Davis is now one of the world’s leading centers for pistachio and nut science.

Here’s something I’ll bet you didn’t know: pistachios can spontaneously combust. Pistachios are rich in unsaturated oils that can slowly oxidize, generating enough heat to ignite large piles if ventilation is poor. Shipping manuals classify them as a “spontaneous-combustion hazard”, a rare but real risk for warehouses and freighters hauling tons of California pistachios across the world. Encyclopedia Britannica notes they are often treated as “dangerous cargo” at sea.

Now, some pistachio biology: The pistachio is dioecious, meaning male and female flowers grow on separate trees. Almonds are not. Farmers plant one male for every eight to ten females, relying on wind for pollination. The trees follow an alternate-bearing cycle, heavy one season, light the next. They don’t produce a profitable crop for about seven years, but once mature, they can keep producing for half a century or more.

California grows nearly all of America’s pistachios, and most of them come from the empire built by Lynda and Stewart Resnick, the power couple behind the Wonderful Company. Their orchards stretch across hundreds of thousands of acres in the Central Valley, transforming a desert landscape into one of the most lucrative nut operations in the world.

Another strange quirk of pistachios is that they are green and, if you look closely, streaked with a faint violet hue. The green comes from chlorophyll, the same pigment that gives leaves their color, which in pistachios lingers unusually long into the nut’s maturity. Most seeds lose chlorophyll as they ripen, but pistachios retain it, especially in the outer layers of the kernel. The purple tint, meanwhile, comes from anthocyanins, antioxidant pigments also found in blueberries and grapes.

As I walked among the pistachio trees recently, I marveled at how alone I was on one of the dirt roads off Highway 99. Not a soul in sight, only the hum of irrigation pumps and the rattle of dry leaves in the breeze. I like to write about the things we all see and experience in California but rarely stop to look at closely. Pistachios are one of those things. If you’ve ever driven through the San Joaquin Valley, you’ve seen how the landscape stretches for miles in orderly rows of pistachio trees. It’s easy to forget, amid the fame of Silicon Valley and Hollywood, that so much of California’s wealth still comes from the land itself, from agriculture and other extractive industries. The pistachio boom is a story of astonishing scale, but it’s also riven with the contradictions and complexities of modern California itself, where innovation and exploitation often grow from the same soil.

Ten Essential Books About California’s Nature, Science, and Sense of Place

Support California Curated with a small donation.

You can scroll endlessly through TikTok and Instagram for quick bursts of California’s beauty, but to truly sink into a subject, and to savor the craft of a great writer, you need a book. I’m an avid reader, and over the past decade I’ve dedicated a large section of my bookshelf to books about California: its wild side, its nature, and its scientific wonders.

There are surely many other books that could be included in this top ten list, but these are the finest I’ve come across in the years since returning to live in the state.They capture the extraordinary diversity of California’s landscapes and wildlife, found nowhere else on Earth, and many also explore issues and themes that hold deep importance for the state and its people. Although I’ve read some of these titles digitally, I love having many of them in print, because there are few things more satisfying than settling into a beach, a forest campsite, or a favorite chair at home with a beautifully made book in hand.

California Against the Sea: Visions for Our Vanishing Coastline by Rosanna Xia

I first discovered Rosanna Xia’s work through her stunning exposé on the thousands of DDT barrels found dumped on the seafloor near Catalina Island. It remains one of the most shocking, and yet not technically illegal, environmental scandals in California’s history.

Her recent book, California Against the Sea: Visions for Our Vanishing Coastline, is a beautifully written and deeply reported look at how California’s coastal communities are confronting the realities of climate change and rising seas. Xia travels the length of the state, from Imperial Beach to Pacifica, weaving together science, policy, and personal stories to show how erosion, flooding, and climate change are already reshaping lives. What makes the book stand out is its relative balance; it’s not a screed, nor naïvely hopeful. It nicely captures the tension between human settlement — our love and need to be near the ocean — and the coast’s natural (and unnatural, depending on how you look at it) cycles of change.

Xia is at her best when exploring adaptation and equity. She reminds us that even if emissions stopped today, the ocean will keep rising, and that not all communities have equal means to respond. The stories of engineers, Indigenous leaders, and ordinary residents highlight how resilience and adaptation must be rooted in local realities. I was especially drawn to Xia’s account of the California Coastal Commission, a wildly controversial agency that wields immense power over the future of the shoreline. Yet it was the commission and its early champions, such as Peter Douglas, who ensured that California’s coast remained open and accessible to all, a decision I consider one of the greatest legislative achievements in modern conservation history.

Thoughtful, accessible, and rooted in the coast we all care about, California Against the Sea challenges us to ask a pressing question: how can we live wisely, and with perspective, at the edge of a changing world?

The High Sierra: A Love Story by Kim Stanley Robinson

Kim Stanley Robinson’s The High Sierra: A Love Story is an expansive, heartfelt tribute to California’s most iconic mountain range. Because of the Sierra’s vast internal basins, which are missing from many of the world’s other great mountain ranges, Robinson argues they are among the best mountains on Earth. His point is hard to refute. He makes a convincing case that the Sierra Nevada may be the greatest range in the world, formed from the planet’s largest single block of exposed granite and lifted over millions of years into its dramatic present shape.

Blending memoir, geology (my favorite part of the book), and adventure writing, Robinson chronicles his own decades of exploration in the Sierra Nevada while tracing the forces — glacial, tectonic, and emotional, that shaped both the landscape and his own life.

Considered one of our greatest living science fiction writers (I’ve read Red Mars — long, but superb — and am currently reading The Ministry for the Future — the opening chapter is gripping and terrifying), Robinson might seem an unlikely guide to the granite heights of California. Yet reading The High Sierra: A Love Story reveals how naturally his fascination with imagined worlds extends into this very real one. The drama of the range, with its light, vastness, and sculpted peaks and basins, feels like raw material for his other universes.

The Dreamt Land by Mark Arax

The Dreamt Land is a portrait of California’s Central Valley, where the control of water has defined everything from landscape to power (power in the form of hydroelectric energy and human control over who gets to shape and profit from the valley’s vast resources). Blending investigative journalism, history, and memoir, Arax explores how the state’s rivers, dams, and aqueducts turned desert into farmland and how that transformation came at immense ecological and social cost.

I’ve read several Arax books, but this one is my favorite. He’s one of the finest writers California has produced. He writes with passion and clarity, grounding his ideas in decades of firsthand experience with California’s land and water. His focus on the fertile Central Valley, where he grew up as a reporter and farmer’s son, gives the book both intimacy and authority, revealing how decisions about water shape not just the landscape but the people who depend on it. There are heroes and villains, plenty of the latter, and all of them unmistakably real. Yet Arax’s prose is so fluid and eloquent that you’ll keep reading not only for the story, but for the sheer pleasure of his writing.

Assembling California by John McPhee (1993)

If you’re at all fascinated by California’s wild geology — and it truly is wild, just ask any geologist — this classic from one of the finest nonfiction writers alive is a must-read. McPhee takes readers on a geological road-trip through California, from the uplifted peaks of the Sierra Nevada to the fault-riven terrain of the San Andreas zone. He teams up with UC Davis geologist Eldridge Moores to explain how oceanic plates, island arcs, and continental blocks collided over millions of years to “assemble” the landmass we now call California. His prose is classic McPhee: clean, vivid, perhaps sometimes overly technical, as he turns terms like “ophiolite” and “batholith” into aspects of a landscape you can picture and feel.

What makes the book especially rewarding, especially for someone interested in earth systems, mapping, and the deep time, is how McPhee seamlessly links everyday places with deep-time events. You’ll read about gold-rush mining camps and vineyard soils, but all of it is rooted in tectonics, uplift, erosion, and transformation. I’ve gotten some of my favorite stories here on California Curated from the pages of this book. It can be ponderous at times, but you’ll not regret giving it a try.

The California Lands Trilogy by Obi Kaufman

The Forests of California (2020)

The Coasts of California (2022)

The Deserts of California (2023)

Obi Kaufman’s California Lands Trilogy is one of the most visually stunning and ambitious projects in California natural history publishing. Beginning with The Forests of California, the first of three volumes that reimagine the state not through its highways or cities but through its living systems, Kaufman invites readers to see California as a vast and interconnected organism, a place defined by its natural rhythms rather than human boundaries. Each book is filled with delicate watercolor maps and diagrams by the author himself. The result is part art book and part ecological manifesto, a celebration of the interconnectedness of California’s natural world. Kaufman’s talents as an artist are breathtaking. If he ever offered his original watercolors for sale, I’d be among the first in line to buy them. Taken together, the series forms a panoramic vision of the state’s natural environments.

That said, Kaufman’s books can be dense, filled with data, maps, and cross-references that reward slow reading more than quick browsing. If I’m honest, I tend to dip in and out of them, picking them up when I’m bored or need a break from the latest political bombshell. Every page offers something to linger over, whether it’s a river system painted like a circulatory map or a meditation on the idea of rewilding. For anyone fascinated by California’s natural systems, all Kaufman’s Field Atlases are invaluable companions endlessly worth revisiting.

The Enduring Wild: A Journey Into California’s Public Lands by Josh Jackson

My first job out of college was with the Department of the Interior in Washington, D.C., by far by the nation’s largest land management agency. A big part of that work involved traveling to sites managed by Interior across the country. I came to understand just how vast America’s public lands are and how much of that expanse, measured in millions of acres, is under the care of the Bureau of Land Management (BLM).

Josh Jackson takes readers on a road trip across California’s often overlooked public wilderness, focusing on the lands managed by the BLM, an agency once jokingly referred to as the Bureau of Livestock and Mining. He shows how these so-called “leftover lands” hold stories of geology, Indigenous presence, extraction, and conservation.

His prose and photography (he has a wonderful eye for landscapes) together invite the reader to slow down, look closely at the subtleties of desert mesas, sagebrush plains, and coastal bluffs, and reckon with what it means to protect places many people have never heard of. His use of the environmental psychology concept of “place attachment” struck a chord with me. The theory suggests that people form deep emotional and psychological bonds with natural places, connections that shape identity, memory, and a sense of belonging. As a frequent visitor to the Eastern Sierra, especially around Mammoth Lakes and Mono Lake, I was particularly drawn to Jackson’s chapter on that region. His account of the lingering impacts of the Mining Act of 1872, and how its provisions still allow for questionable practices today, driven by high gold prices, was eye-opening. I came away with new insights, which is always something I value in a book.

I should mention that I got my copy of the book directly from Josh, who lives not far from me in Southern California. We spent a few hours at a cafe in Highland Park talking about the value and beauty of public lands, and as I sat there flipping through the book, I couldn’t help but acknowledge how striking it is. Part of that comes from Heyday Books’ exceptional attention to design and production. Heyday also publishes Obi Kaufman’s work and they remain one of California’s great independent publishers. But much my appreciation for the book also comes from from Jackson himself, whose photographs are simply outstanding.

What makes this book especially compelling is its blend of adventure and stewardship. Jackson doesn’t simply celebrate wildness; he also lays out the human and institutional connections that shape (and threaten) these public lands, from grazing rights to mining to climate-change impacts. Some readers may find the breadth of landscapes and stories a little ambitious for a first book, yet the richness of the journey and the accessibility of the writing make it a strong addition for anyone interested in California’s endless conflict over land use: what should be used for extraction and what should be preserved? While I don’t fully agree with Jackson on the extent to which certain lands should be preserved, I still found the book a wonderful exploration of that question.

The Backyard Bird Chronicles by Amy Tan

Amy Tan’s The Backyard Bird Chronicles is a charming and unexpectedly personal journal of bird-watching, set in the yard of Tan’s Bay Area home. Tan is an excellent writer, as one would expect from a wildly successful novelist (The Joy Luck Club, among others). But she also brings a curiosity and wonder to the simple act of looking across one’s backyard. I loved it. Who among us in California doesn’t marvel at the sheer diversity of birds we see every day? And who hasn’t wondered about the secret lives they lead? A skilled illustrator as well as a writer, she studies the birds she observes by sketching them, using art as a way to closely connect with the natural world around her.

What begins as a peaceful retreat during the Covid catastrophe becomes an immersive odyssey of observation and drawing. Tan captures the comings and goings of more than sixty bird species, sketches their lively antics, as she reflects on how these small winged neighbors helped calm her inner world when the larger world felt unsteady.

My only quibble is that I was hoping for more scientific depth; the book is more of a meditation than a field study. Still, for anyone who loves birds, sketching, or the quiet beauty of everyday nature, it feels like a gentle invitation to slow down and truly look.

“Trees in Paradise” by Jared Farmer

California is the most botanically diverse state in the U.S. (by a long shot), home to more than 6,500 native plant species, about a third of which exist nowhere else on Earth. Jared Farmer’s Trees in Paradise: A California History follows four key tree species in California: the redwood, eucalyptus, orange, and palm. Through these examples, Farmer reveals how Californians have reshaped the state’s landscape and its identity. It’s rich in scientific and historical detail. I have discovered several story ideas in the book for California Curated and learned a great deal about the four trees that we still see everywhere in the California landscape.

In telling the story of these four trees (remember, both the eucalyptus and the palm were largely brought here from other places), Farmer avoids easy sentimentality or harsh judgment, instead exploring how the creation of a “paradise” in California came with ecological costs and profoundly shaped the state’s identity. While the book concentrates on those four tree categories, its detailed research and insight make it a compelling read for anyone interested in the state’s environment, history, and the ways people shape and are shaped by land.

California Is a Nobel Powerhouse

Would you support us? Just a few bucks. We’d appreciate it!

You can keep your Oscars, Emmys, Grammys, and Tonys. Take your Pulitzers, Bookers, and Peabodys, too. Even the Pritzker and the Fields Medal don’t quite measure up. For me, nothing competes with the Nobel Prize as a symbol that someone has truly changed the world.

I’m not a scientist, but my mind lives in that space. Science, more than anything else, runs the world and reshapes it. This newsletter was born out of my fascination with how things work and the quiet mechanics behind the visible world and my love for all that California has to offer in the way of innovation and natural beauty. I love standing in front of something familiar and asking: why? how? what exactly is going on here? And nothing satisfies that intense curiosity more than science.

That said, I’ve never loved the word science. It feels cold and sometimes intimidating, as if it applies to people in lab coats and not to everyone else. I kinda wish there were a better word for that spirit of discovery that lives in all of us. Maybe it’s wonder. Maybe curiosity. I dunno. “Science” turns people off sometimes, unfortunately.

Whatever you call it, the Nobel Prize represents the highest acknowledgment of that pursuit. It is the world’s way of saying: this mattered. This changed something. And there are few places (if any) on Earth that can rival California when it comes to the number of people who have earned that honor.

This year, 2025, was no different. Three of the Nobel Prizes announced this week carried California fingerprints, adding to a tradition that stretches back more than a century.

The Nobel Prize in Physiology or Medicine came first. It went to Mary Brunkow, Shimon Sakaguchi, and Fred Ramsdell, the last of whom studied at UCLA and UC San Diego. (In epic California fashion, Ramsdell, who studied at UCLA and UC San Diego, didn’t even learn he’d become a Nobel laureate until after returning from a trip deep into the Wyoming wilderness, where he’d been out of contact with the outside world. What’s more Californian than that?) Their research on regulatory T cells explained how the immune system knows when to attack and when to stand down. Ramsdell’s discovery of a key gene that controls these cells has transformed how scientists think about autoimmune disease and organ transplantation.

Next came the Nobel Prize in Physics, awarded to John Clarke of UC Berkeley, Michel H. Devoret of UC Santa Barbara and Yale, and John M. Martinis of UC Santa Barbara (big shout out to UCSB!). Their award honored pioneering work that revealed how the strange laws of quantum mechanics can be seen in circuits large enough to hold in your hand. Beginning in Clarke’s Berkeley lab in the 1980s, the trio built superconducting loops that behaved like subatomic particles, “tunneling” and flipping between quantum energy states. Those experiments helped create the foundation for today’s quantum computers.

The Chemistry Prize followed a day later, shared by Susumu Kitagawa, Richard Robson, and Omar M. Yaghi of UC Berkeley for discoveries in metal–organic frameworks, or MOFs. These are crystalline materials so porous that a single gram can hold an entire roomful of gas (mind blown). MOFs are now used to capture carbon dioxide, filter water, and even pull drinking water from desert air. Yaghi’s Berkeley lab coined the term “reticular chemistry” to describe this new molecular architecture. His work has become one of California’s most important contributions to the climate sciences.

Those three announcements in as many days lit up California’s scientific community, has garnered many headlines and carried on a tradition that has made the state one of the world’s most reliable engines of Nobel-level discovery.

The University of California system now counts 74 Nobel Prizes among its faculty and researchers. 23 in physics and 16 in chemistry. Berkeley leads the list, with 26 laureates, followed by UC San Diego, UCLA, UC Santa Barbara, and UC San Francisco. Even smaller campuses, such as UC Riverside, have ties to winners like Barry Barish, who shared the 2017 Nobel in Physics for detecting gravitational waves.

Caltech, which I have written about extensively and is quite close to my own home, counts 47 Nobel laureates (faculty, alumni, or postdocs). Its history is the stuff of legend. In 1923, Robert Millikan won for measuring the charge of the electron. In 1954, Linus Pauling received the Chemistry Prize for explaining the nature of the chemical bond. He later won the Peace Prize for his anti-nuclear activism, making him the only person to win two unshared Nobels.

Stanford University sits not far behind, with 36 Nobel winners in its history and about 20 currently active in its community. From the development of transistors and lasers to modern work in medicine and economics, Stanford’s laureates have changed the modern world in ways that is impossible to quantify, but profound in their impact.

These numbers tell a clear story: since the mid-twentieth century, about one in every four Nobel Prizes in the sciences awarded to Americans has gone to researchers based at California institutions, an extraordinary concentration of curiosity, intellect, and ambition within a single state.

California’s Nobel dominance began early. In the 1930s, UC Berkeley’s Ernest Lawrence invented the cyclotron, a device that would transform physics and eventually medicine. Caltech, meanwhile, became a magnet for the world’s brightest physicists and chemists.

Over the decades, California’s universities turned their focus to molecular biology, biochemistry, and genetics. In the 1980s, the state’s physicists and engineers drove advances in lasers, semiconductors, and now, quantum circuits. And as biotechnology rose, San Diego and the Bay Area became ground zero for breakthroughs in medicine and life sciences. One of the great moments in genetics took place in Asilomar on the coast.

This is all about more than geography and climate (although those are a big sell, for sure). California’s research institutions kick ass because they operate as ecosystems rather than islands. Berkeley physicists collaborate with engineers at Stanford. Caltech chemists trade ideas with biotech firms in San Diego. Graduate students drift between labs, startups, and national research centers like Lawrence Livermore and JPL. The boundaries between university and industry blur, with campuses like Stanford turning breakthrough discoveries into thriving commercial ventures (look how many of our big tech brains came out of Stanford). In California, research doesn’t end in the lab, it often turns into companies, technologies, and treatments that generate both knowledge and enormous economic value. Just look at AI today.

I think the secret is cultural. Over the years, I’ve lived on the East coast for almost two decades, and abroad for several as well, and nothing compares to the California vibe. California has never been afraid of big risks. Its scientists are encouraged to chase questions that might take decades to answer (see our recent story on just this idea). There’s an openness to uncertainty here that works well in the natural sciences, but can also be found in Hollywood, Silicon Valley and, of course, space exploration. 

When next year’s round of early morning calls comes from Stockholm, it is a good bet that someone in California will pick up. Maybe a physicist in Pasadena, a chemist in Berkeley, or a physician in La Jolla. Maybe they’ll pick up the phone in bed, maybe a text from a spouse while camping, or on a morning jog. That’s when a Swedish-accented voice tells them that the world has just caught up to what they’ve been quietly building for years.

The story of corals in the modern age on this planet is one of near-total despair. I’ve done several stories on corals and have spent many hours diving reefs around the world, from the Mesoamerican Reef in Belize to the unbelievably robust and dazzling reefs in Indonesia. There are still some incredible places where corals survive, but they are becoming fewer and farther between. I don’t want to get too deep into all the statistics, but suffice it to say: scientists estimate that we have already lost about half of the world’s corals since the 1950s, and that number could rise to as much as 90 percent by 2050 if current rates of bleaching and die-offs continue.

Would you support us? Just a few bucks. We’d appreciate it!

What’s crazy is that we still don’t completely understand corals, or exactly why they are dying. We know that corals are symbionts with microscopic algae called zooxanthellae (pronounced zo-zan-THEL-ee). The corals provide cover, a place to live, and nutrients for the algae. In return, the algae provide sugars and oxygen through photosynthesis, fueling coral growth and reef-building. But when the planet warms, or when waters become too acidic, the relationship often collapses. The algae either die or flee the coral. Without that steady food source—what one scientist I interviewed for this story called “a candy store”—corals turn ghostly white in a process known as bleaching. If stressful conditions persist, they starve and die. 

But why?

“We still have no idea, physiologically, in the types of environments where bleaching predominates, whether the animal is throwing them out because it’s going to try to survive, or whether the little tiny plants say to the animal, ‘look, we can’t get along in this environment, so we got to go somewhere else’” says Dr. Jules Jaffe, an oceanographer at the Scripps Institution of Oceanography at the University of California, San Diego in La Jolla, California, and the head of the Jaffe Laboratory for Underwater Imaging. 

The Great Barrier Reef, once Earth’s largest living structure, has suffered five mass bleaching events since 1998, and vast stretches have become little more than graveyards of coral skeletons. The scale of this ecological disaster is almost unimaginable. And so scientists around the world are in a race to figure out what’s happening and how to at least try to slow down the bleaching events sweeping through nearly every major reef system.

One place where scientists are making small strides is at the Jaffe Lab, which I visited with my colleague Tod Mesirow and where researchers like Dr. Jaffe and Dr. Or Ben-Zvi have developed a new kind of underwater microscope that allows them to get close enough to corals to actually see the algae in action. 

This is no small feat. Zooxanthellae are only about 5–10 microns across, about one-tenth the width of a human hair, and invisible to the naked eye. With the new microscope and camera system, though, they can be seen in astonishing detail. The lab has captured unprecedented behavior, including corals fighting with each other for space, fusing together, and even responding to invading algae.

When I first reported on this imaging system years ago, it was still in its early stages. At the time, it was known as the BUM for Benthic Underwater Microscope. Since then, the Scripps team has added a powerful new capability: a pulsing blue light that lets them measure photosynthesis in real time. They call it pulse amplitude modulated light or PAM, and so now the system is known as the BUMP.

Here’s how it works: blue excitation light stimulates the algae’s chlorophyll, which then re-emits some of that energy as red fluorescence. By tracking how much of this red fluorescence is produced, researchers can calculate indices of photochemical efficiency, essentially how well the algae are converting light into energy for photosynthesis. This doesn’t give a direct count of sugars or photons consumed, but it does provide a reliable window into the health and productivity of the algae, and by extension, the coral itself.

What’s crucial is that all of this imaging takes place in situ—right in the ocean, on living reefs—rather than in the artificial setting of an aquarium or laboratory.

New tools are essential if we’re going to solve many of our biggest problems, and it’s at places like Scripps in California where scientists are hard at work creating instruments that help us see the world in entirely new ways. “There’s so much to learn about the ocean and its ecosystems, and my own key to understanding them is really the development of new instrumentation,” says Jaffe.

Dr. Ben-Zvi gave us a demonstration of how the system works in an aquarium holding several species of corals, including Stylophora, a common collector’s coral. She showed us the remarkable capabilities of the camera-microscope, which illuminated and brought into crisp focus the tiny coral polyps along with their algal partners. On the screen we watched them in real time, tentacles waving as they absorbed the flashes of light from the BUMP, appearing, almost, as if they were dancing happily.

What this new tool allows scientists to do is determine whether corals may be under stress from factors like warming seas, pollution, or disease. Ideally, these warning signs are detected before the corals expel their zooxanthellae and bleach. Researchers are also learning far more about the everyday behavior of corals: something rarely studied in situ, directly in the ocean. 

That in-their-native-environment aspect of the work is crucial, because corals often behave very differently in aquariums than they do on wild reefs. That’s where this microscope promises to be a powerful tool: offering insights into how corals really live, fight, and respond to stress.

Of course, what we do once we document a reef under stress is another matter. Dr. Ben-Zvi suggests there may be possibilities for remediation, though she admits it’s difficult to know exactly what those are. Perhaps reducing pollution, limiting fishing, or cutting ship traffic in vulnerable areas could help. But given that we seem unable—or unwilling—to stop the warming of the seas, these measures can feel like stopgaps rather than solutions. Still, knowledge is the foundation for any action, and this new tool is a breakthrough for coral imaging. If deployed widely, it could generate an invaluable dataset for researchers around the globe. The scientists behind it even hope to build multiple systems, perhaps commercializing them, to vastly expand the reach of this kind of monitoring.

But even Jaffe concedes it may already be too late: “Could a world exist without corals? Yeah, I think so,” he said. “It would be sad, but it’s going that way.”

All the same, the images the tool produces are breathtaking, and at the very least, they might jolt people into realizing that this is a crisis worth trying to solve. If we can’t, then future generations will be left only with these hauntingly beautiful images to remember the diverse and gorgeous animals that once flourished along the edges of the sea.

Is that valuable? Yes, but not nearly as valuable as saving the living reefs themselves. Dr. Jaffe told us,

“I’m on a mission to help people feel empathy toward the creatures of the sea. At the same time, we need to learn just how beautiful they are. For me, the combination of beauty and science has been at the heart of my life’s work.”

His words capture the spirit of this research. The underwater microscope isn’t just a scientific instrument. It’s a lens into a hidden world, one that may inspire people to care enough to act before it’s gone. Too bad the clock is ticking so fast.

A Tiny California Seaweed Could Make a Big Dent in Livestock Methane

Inside a long, brightly lit basement lab at the Scripps Institution of Oceanography at UC San Diego, a large aquarium filled with live corals sits against the wall, the vibrant shapes and colors of the coral standing out against the otherwise plain white surroundings. Nearby, in a side alcove, dozens of glass flasks bubble with aerated water, each holding tiny crimson clusters of seaweed swirling in suspension, resembling miniature lava lamps. These fragile red fragments, born in California and raised under tightly controlled conditions, are part of a global effort to harness seaweed to fight climate change.

Cattle and other ruminant livestock are among the largest contributors to methane emissions worldwide, releasing vast amounts of the gas through digestion and eructation. Burps, not farts. The distinction is not especially important, but it matters because critics of climate science often mock the idea of “cow farts” driving climate change. In reality, the methane comes primarily from cow burps, not flatulence.

But I digress.

Globally, livestock are responsible for roughly 14 percent of all human-induced greenhouse gases, with methane from cattle making up a significant portion of that total. The beef and dairy industries alone involve more than a billion head of cattle, producing meat and milk that fuel economies but also generating methane on a scale that rivals emissions from major industrial sectors. Because methane is so potent, trapping more than 80 times as much heat as carbon dioxide over a 20-year period, the livestock industry’s footprint has become a central focus for climate scientists searching for solutions. 

Enter Jennifer Smith and her colleagues at the Smith Lab at Scripps in beautiful La Jolla, California. Their team is tackling urgent environmental challenges, from understanding coral die-offs to developing strategies that reduce greenhouse gas emissions, among them, the cultivation of seaweed to curb methane from cattle.  

The seaweed species is Asparagopsis taxiformis. Native to tropical and warm temperate seas and found off the coast of California, in fact right here off the coast in San Diego, it produces natural compounds such as bromoform that interfere with the microbes in a cow’s stomach that generate methane gas, significantly reducing the production of methane and, of course, it’s exhalation by the animals we eat. It turns out the seaweed, when added to animal feed can be very effective:

“You need to feed the cows only less than 1% of their diet with this red algae and it can reduce up to 99% of their methane emissions,” said Dr. Or Ben Zvi, an Israeli postdoctoral researcher at Scripps who studies both corals and seaweeds.

Trials in Australia, California, and other regions have shown just how potent this seaweed can be. As Dr. Ben Zvi indicated, even at tiny doses, fractions of a percent of a cow’s feed, other studies have shown that it can reduce methane by 30 to 90 percent, depending on conditions and preparation. Such results suggest enormous potential, but only if enough of the seaweed can be produced consistently and sustainably.

“At the moment it is quite labor intensive,” says Ben Zvi. “We’re developing workflows to create a more streamlined and cost-effective industry.”

Which explains to bubbling flasks around me now.

The Smith lab here at Scripps studies every stage of the process, from identifying which strains of Asparagopsis thrive locally to testing how temperature, light, and carbon dioxide affect growth and bromoform content. Dr. Ben Zvi is focused on the life cycle and photosynthesis of the species, refining culture techniques that could make large-scale cultivation possible. At Scripps, environmental physiology experiments show that local strains grow best at 22 to 26 °C and respond well to elevated CO₂, information that could guide commercial farming in Southern California.

The challenges, however, are considerable. Wild harvesting cannot meet demand, and cultivating seaweed at scale requires reliable methods, stable yields, and affordable costs. Bromoform content varies widely depending on strain and growing conditions, so consistency remains an issue. Some trials have noted side effects such as reduced feed intake or excess mineral uptake, and long-term safety must be established since we’re talking about animals that we breed and raise to eat.

“It’s still a very young area, and we’re working on the legislation of it,” says Ben Zvi. “We need to make it legal to feed to a cow that eventually we either drink their milk or eat their meat. We need for it to be safe for human consumption.”

And, of course, large-scale aquaculture raises ecological questions, from nutrient demands and pollution to the fate of volatile compounds like bromoform.

To overcome these obstacles, collaborations are underway. UC San Diego and UC Davis have launched a pilot project under the UC Carbon Neutrality Initiative to test production methods and carbon benefits. In 2024, CH4 Global, a U.S.-based company with operations in New Zealand and Australia that develops seaweed feed supplements to cut livestock methane, partnered with Scripps to design cultivation systems that are efficient, inexpensive, and scalable. Within the Smith Lab, researchers are continuing to probe the biology of Asparagopsis, mapping its genetics, fine-tuning its culture, and testing ways to maximize both growth and methane-suppressing compounds.

At a time when university-based science faces immense pressures, the Smith Lab at Scripps provides a glimpse of research that is making a real impact. The coral tanks against the wall belong to another project at the lab, and we have another story coming soon about the research that readers will find very interesting, but the bubbling flasks in the alcove reveal how breakthroughs often start with small details. In this case, the discovery that a chemical in a widely available seaweed could have such a dramatic, and apparently harmless, effect on the methane that animals make in their guts. These modest but powerful steps are shaping solutions to global challenges, and California, with its wealth of scientific talent and institutions, remains at the forefront. It is one of many other stories we want to share, from inside the labs to the wide open spaces of the state’s natural landscapes.

Riding Wave Energy in Los Angeles

Turning the steady motion of the Pacific into clean electricity, Eco Wave Power’s pilot at the Port of Los Angeles tests whether wave energy can become a real piece of California’s renewable future.

Would you support us? Just a few bucks. We’d appreciate it!

Earlier this week at the Port of Los Angeles, I stood with my colleague Tod Mesirow as a blue ribbon was cut and seven steel floaters dipped into the tide at AltaSea Marine Center in San Pedro. It was a milestone moment: the first onshore wave-energy project in the United States.

Wave energy is the process of converting the up-and-down motion of ocean waves into electricity. Engineers have been experimenting with the idea for decades, with pilot projects around the world, but very little major success. While no country has yet deployed wave power at large scale, efforts like this onshore wave-energy project in the United States aim to prove it can become a reliable part of the renewable mix.

Eco Wave Power, the company behind the technology, framed the event as the beginning of a new chapter in renewable energy, one that could eventually bring the restless motion of the sea onto the grid on a meaningful scale. As my instagram feed will attest, big waves contain a lot of power (the algorithm knows I love big wave surfing). But that’s not what this project is about. Instead, it relies on the small, steady waves that are almost always present along the California coast. Each rise and fall pushes eco-friendly hydraulic fluid through a system of pistons and pipes, building pressure that drives a motor connected to a generator. The process transforms the ocean’s rhythm into electricity, which can then be fed into the nearby grid. This approach doesn’t depend on dramatic swells, but on the reliable pulse of the sea.

Inna Braverman, the CEO of Eco-Wave told me that the pilot project’s small capacity is a proof of concept for a much larger series of installations along the California coast. “The installed capacity of this conversion unit is 100 kilowatts,” Braverman says. “The amount of power actually generated depends on the height and the weight period of the waves. So, 100 kilowatt installed capacity is up to 100 households.”

The choice of location is not incidental. The Port of Los Angeles is one of the busiest harbors in the world, lined with piers, breakwaters, and aging industrial structures that provide ideal platforms for attaching wave-energy devices. Unlike offshore wind, which requires building foundations in open water, Eco Wave Power’s design capitalizes on existing waterfront infrastructure, keeping costs lower and operations more accessible. The port also happens to be surrounded by electrical infrastructure, with substations and transmission lines nearby. That means energy generated by the floaters can be quickly sent into the grid, without the long and costly buildouts often required for renewable projects in remote places. And perhaps most importantly, this demonstration is unfolding at the doorstep of greater Los Angeles, a region of nearly 19 million people where clean energy demand is immense. To test wave power here is to bring it directly into the heart of a major population center, where its success or failure will matter on a national scale.

Congresswoman Nanette Díaz Barragán called the project “history in the making” and tied it to her proposed $1 billion Marine Energy Technologies Acceleration Act, aimed at scaling up wave and tidal systems nationwide. California has already passed Senate Bill 605, directing the creation of a wave-energy roadmap, and local leaders like Port of Los Angeles officials spoke of the technology as a key tool to help the San Pedro Bay port complex reach its zero-emission goal within the next decade.

For Eco Wave Power, this was not just a ribbon cutting but the opening of a U.S. market that has long been cautious about marine renewables. Braverman announced future projects in Taiwan, India, and Portugal, while partners from Africa described feasibility studies in South Africa and Kenya. Taiwan’s pilot at Suao Port could grow to 400 megawatts, while the Port of Ngqura in South Africa is being studied as a showcase for diversifying away from coal.

The optimism is real, but the facts are more sobering. Wave energy has been tested in several places around the globe, often with promising beginnings but mixed long-term outcomes. The Mutriku plant in Spain has generated steady power for more than a decade, but at modest efficiency. Sweden’s Sotenäs project closed after just a few years of operation. The ocean is brutal on hardware: salt, storms, and marine growth wear down even the best-engineered devices. Costs remain high, and grid-scale capacity is far from proven.

Still, the potential is undeniable. The International Energy Agency estimates that global wave and tidal power could, in theory, supply a significant fraction of the world’s electricity needs. Unlike solar or wind, waves are relatively constant, offering a stable, predictable form of renewable generation. That reliability could make wave energy an important complement to other renewables, especially as grids grow more complex and storage remains expensive.

But honesty requires saying wave power will not, on its own, solve the climate crisis. It is a piece of the puzzle, not the whole picture. The bulk of clean energy in the near term will continue to come from solar and wind, with geothermal, hydropower, and nuclear filling important roles. If wave energy finds its footing, it will likely be as a regional player, most valuable in countries with long, energetic coastlines and strong political will to diversify.

Watching the floaters rise and fall yesterday, we could sense the tension between ambition and reality. This pilot is small, but it demonstrates a willingness to try something new, to take the step from research tank to open water. Braverman called it “opening the door to a new era of clean energy.” That door may open slowly, and perhaps only partway, but the act of trying matters. The ocean is vast and restless, and if we can learn to work with it, wave energy could one day be one of the many forces nudging us toward a sustainable future.
