Electricity prices in California are on the rise and they are forecast to go much, much higher in the future.  Climate change is wreaking havoc across the world even as we are pumping more greenhouse gases into the atmosphere than ever before.  And electric utilities want more and more control over the energy they buy or produce and sell to you.  Finally, the Trump Administration is doing its best to undermine the renewable energy that could address both issues.

What if there were a cost-effective way to address all three issues and giving communities more control over the...

Summer is over and the rainy season looms ahead.  We are being promised a wild, wet and wooly winter, with a “Super” El Niño. Temperatures in the tropical Pacific are going up leaving marine mammals to starve and die. There have been few hurricanes in the Atlantic this year while, with two months left in the Pacific hurricane season, we are getting toward the end of the alphabet.  Can atmospheric rivers, flooding and historic tides be far behind.

Hear a rerun of an interview about California weather and climate with Dr. Daniel Swain, a scientist with the Uni...

We’ve all heard about the terrible Himalayan flash flood that traveled nearly 100 km down the Lende Kholā and Trishuli̇̄ Kholā rivers on the Nepal-Chinese border, devastating towns and villages along the way, killing at least 1,250 people and leaving more than 5,000 missing in the two countries.  The causes remain under investigation, but climate change appears to have played a major role in the disaster.  Join host Ronnie Lipschutz for a conversation with Jonathan Mingle, an independent journalist and author whose reporting and writing is focused on the science and politics of climate change, energy, health, and technology.  In 2015, he published...

Local food systems are of great importance to the Monterey Bay Region and, indeed, to California, and there is a growing number of small farms across the state supplying these systems.  Join Ronnie Lipschutz for a conversation with Josefina Lara Chavez, Executive Director of RegenerationLA, the Latine Alliance in Agroecology and the Food System, which has just launched Rancho Coyote Viejo in south San Benito County. The Rancho is a 25-acre pilot land access farm for beginning farmers practicing regenerative and organic agriculture, along with a demonstration farm to support RegenerationLA’s educational and technical assistance activities.  The farm is a...

There are lots of dystopian futures floating around in the air and on the air.  Imagining the future is never really about the future; it’s more like commentary about the present. “Conjunctural futures” extrapolate from the present: they are not-so-distant, generational futures that could or might be. What might those conjunctural futures look like? Can we imagine a positive one?  And what must we do to get there?  Join host Ronnie Lipschutz for a conversation with Kim Stanley Robinson, author, visionary and “conjunctural futurist,” for a conversation about his work, his philosophy and his speculations on the conjunctural future. Robin...

Nuclear weapons have been with us for 80 years.  There are fewer today than was the case at the height of the Cold War, but there are more countries with nukes than ever before.  Some heads of state have been, of late, threatening to use them.  If you’ve seen Kathryn Bigelow’s recent film, “House of Dynamite,” you’ll know that human psychology is the linchpin on which the entire system of nuclear deterrence rests: would the President (or Premier or whatever) exchange their capitals for others?  Trade Washington, DC for Moscow or Beijing?

There is reason to be concerne...

 The Trump Administration has declared war on California and is hell-bent on eliminating any and all of the state’s environmental protections. As part of its “drill baby, drill” strategy, it is moving to open the California Coast to oil drilling and to increase exploration and extraction on BLM lands across the state.  And not wanting to stay out of the action, the Supreme Court recently ruled that the makers of the herbicide Roundup do not have to warn users of cancer risks associated with its use. But wait, there’s more! The bad news just keeps on coming! Join host...

The Santa Cruz Mountains cover more than 1,000 square miles of the Central California Coast, running from just south of San Francisco all the way down to the Salinas Valley.  The region has been actively stewarded for thousands of years by indigenous people and is a place of significant cultural, biological, and environmental diversity which supports many native plant and animal species found nowhere else on Earth.  Join host Ronnie Lipschutz for a conversation about the mountains and the network with Dylan Skybrook, Manager of the Santa Cruz Mountains Stewardship Network, a collaboration of twenty-six organizations engaged in land stewardship in...

Over the past four centuries, the transformation of the Greater San Francisco Bay Region has been extraordinary.  What was once a near paradise for a few hundred thousand indigenous First Peoples is now home to nearly 8 million whose accumulated activities since the arrival of Europeans have created an industrialized landscape interspersed with large areas of open space where nature is in recovery. How did this happen? Join host Ronnie Lipschutz for a conversation with David D. Schmidt, who spent two decades writing San Francisco Bay Area—An Environmental History, published by Back Country Press in 2025, and which is this yea...

Who knew that ponds make music?  To the eye and ears, they seem silent and tranquil—except at night when, maybe, choruses of frogs serenade listeners.  But ponds are much noisier than that: you have to be very quiet and have the right equipment to really hear what’s going on.  And there is a lot going on: both the critters and the plants speak out.  Indeed, nature is full of sounds, many of them musical and, quite possible, the forerunners of human music.

Join host Ronnie Lipschutz for a conversation with Dr. David Rothenberg, scholar, author, musician...

The attack on Iran by the United States and Israel demonstrated, among other things, the necessity of a rapid transition to renewable fuels, like solar and wind.  The technologies for capturing and converting them into usable form are heavily dependent on critical minerals, such as lithium, cobalt and others. Indeed, critical minerals are driving a new wave of resource nationalism and extraction around the globe, many of them being eyed by President Trump as potential regions of intervention and conquest.  What does the gold rush for these minerals portend for world politics and economics? Are we on the brink of...

Perfluoroalkyl and polyfluoroalkyl substances—commonly known as PFASs and "forever chemicals"—have become ubiquitous in the environment and are being found almost everywhere in soil, water, plants and bodies.    The Trump Administration has lowered drinking water standards for PFASs presence but that does not mean the stuff has gotten safer. You might know PFASs in the form of Teflon which, for many years, are applied to non-stick cookware so those eggs slide off the pan.  But if you overheat that pan, the Teflon might also slide off.  PFASs slide off of many other things, as well. The environmental and health i...

We’ve heard a lot about the problem of microplastics pollution. Just how bad is it?  What are its causes?  What are microplastics doing to us and the world?  Is anything being done to stem the accelerating production and consumption of plastics that end up in our water, our air, in animals, and in human bodies? Join host Ronnie Lipschutz for a conversation about microplastics with Dr. Myra Finkelstein, Adjunct Professor in the Microbiology and Environmental Toxicology Department at UC Santa Cruz and Dr. Steven Mentor a Santa Cruz climate activist and long-time environmentalist. Finklestein has been examining the health...

Indigenous peoples around the world are under threat, especially from massive development projects engineered by governments and corporations, which promise to destroy the lands, forests and waters on which those peoples depend.    In an article that appeared in a recent issue of The New York Review of Books, “We Think They'll Kill Someone” journalist Anjan Sundaram reported on one such project in the Southern Mexico Oaxacan town of San Blas Atempa, where a new factory will wipe out a communally owned forest.

Join host Ronnie Lipschutz for a conversation with Sundaram. He is an Indian author, war reporte...

The State of California has created a program called “Transformative Climate Communities,” focused on making low-income, urban areas more resilient, efficient and responsive to housing, energy and climate challenges. What does this mean on the ground? Join host Ronnie Lipschutz for a conversation with Nancy Faulstitch, Executive Director and Eloy Ortiz, Special Projects Manager at Regeneración Pajaro Valley which, along with Monterey County, received a TCC planning grant in 2021. They have been leaders in this effort and will talk about the planning process and what happens next. Regeneración is a Pajaro Valley non-profit that builds bridges between reside...

The world’s cities are big and getting bigger.  By 2050, 80% of the world’s people will live in cities. Can cities be made sustainable?  Who is thinking about this? Join host Ronnie Lipschutz for a conversation with Peter Calthorpe, architect and urban designer with HDR, a global company specializing in architecture, engineering, environmental and construction services. Over the past 45 years, Calthorpe has been a primary advocate for sustainable communities, the New Urbanism and transit-oriented development. His most recent publications are "Ending Global Sprawl: Urban Standards for Sustainable and Resilient Development" for the World Bank and “Grand Boulevards and the AB2011 R...

Over the past several decades, there has been a concerted effort by biologists, economists and others to put a value on nature’s services: what would it cost, for example, to provide clean water the way nature does?  Oxygen, photosynthesis, soil?  Early estimates were around $30 trillion per year; arguably, today they are much higher, over $100 trillion.  But getting from hypothetical calculations to actual incorporation into real work policy and development projects is no easy task.  Join host Ronnie Lipschutz for a conversation with Daniel Chiu Suarez, Assistant Professor of Environmental Studies at Middlebury College in Vermont. He has just publis...

The removal of four dams from the Klamath River in Northern California is rapidly becoming one of the great recent success stories in conservation and restoration.  The riverbank habitat is returning to its former condition and salmon have been spotted swimming upriver past the sites where the dams once blocked their passage.  Along with this comes the restoration of the indigenous peoples’ way of life, heavily dependent on those fish.  Join Host Ronnie for an update on the Klamath in a conversation with Amy Bowers Cordalis, who has just published The Water Remembers—My Indigenous Family’s Fight to Save a Ri...

Many listeners are probably familiar with the tags found in hotel bathrooms that read: “Save Our Planet,” followed by instructions about reusing and replacing towels, and concluding “Thank you for helping us converse the Earth’s vital resources.”  Reusing towels might help conserve the hotel’s financial resources but does that make any difference for the Planet?  Such “lifestyle environmentalism” is widespread, providing a sense of doing something in a world in which collective action is so difficult.  In two weeks, join host Ronnie Lipschutz for a conversation with Dr. Michael Maniates, for a conversation about his new book, The Living-Green My...

Lake Tahoe is one of California’s natural jewels but it is under siege and increasingly awash in plastic wastes, as visitors carelessly dispose of bottles and packages and discarded items degrade into small pieces washed into the lake.  What happens to that stuff? As we have been learning, microplastics are everywhere, in the environment and in our bodies.  What are their impacts on people, animals and nature?  Join host Ronnie Lipschutz for a conversation with Madison “Madio” Wallner, a UCSC PhD student in Environmental Science, who is studying microplastics and tire particles in Tahoe’s bottom sediments.

The Kenneth S. Norris Center at UC Santa Cruz is one of the little-known jewels of the campus as well as the Monterey Bay Region. Ken Norris was an American marine mammal biologist, conservationist, naturalist, and co-founder of SeaWorld, as well as a professor of natural history at UCSC.  He was the creator of the UC Natural Reserve System, too.  The Norris Center holds a vast collection of insects, plants and seeds from the Santa Cruz Mountains and supports classes, internships and research by UCSC students, faculty and staff.  Join me in two weeks for a conversation about the Nor...

If you venture out into parks, farms and gardens with various flowering species, you are almost sure to see European honeybees flying about.  When we think of bees, those are the ones that usually come to mind.  But there are more than 1,600 native bee species in California alone, and many of those are threatened with extinction.  Krystle Hickman is a National Geographic Explorer, conservation photographer, and native bee expert who uses her photography to raise awareness about the decline of native bee species and their complex ecosystems.  Her new book, The ABCs of California Native Bees, a compendium of text...

Millions of Americans see themselves as "conflicted omnivores," worrying about the ethical and environmental implications of their choice to eat animals. Yet their attempts to justify their choices only obscure the truth of the matter. Join host Ronnie Lipschutz for a conversation with Dr. John Sabonmatsu, Professor of Philosophy at Worcester Polytechnic Institute in Massachusetts.  His recently published book, The Omnivore’s Deception, provides a deeply observed philosophical meditation on the nature of our relationship with animals.  Sabonmatsu argues that killing and eating animals is unethical, regardless of whether they are "free range" or factory farmed. The problem with rais...

Even before the publication of Paul Ehrlich’s The Population Bomb in 1968, we heard warnings that humanity would be doomed to a future of famine, hunger and starvation unless industrial agriculture were unleashed to grow food as efficiently as possible in every nook and cranny of the world’s arable lands to feed the “ten billion.” Those warnings continue today. But is it correct? In “The Enduring Fantasy of ‘Feeding the World’,” a recent article in the journal Spectre, four members of the Agroecology Research-Action Collective challenge those who make this claim.  Join host Ronnie Lipschutz for a conversation about feeding the...

Tom Lehrer, the musical satirist par excellence of the 1950s and 1960s, died this past July at age 97.  Many listeners and their progeny grew up listening to and singing his compelling compositions: easy to remember, easy to sing and easy to finish.  Who could forget “The Vatican Rag” or “The Elements?”

What some might not know is that, from 1972 to 2001, in flight from East Coast winters, Tom also taught math and theater at UC Santa Cruz, as a lecturer in American Studies.  Along the way, he made many friends and inspired countless students.

In October 2020, Governor Newsom issued Executive Order N-82-20 which establishes a state goal of conserving 30% of California’s lands and coastal waters by 2030 – known as 30x30. The 30x30 goal is intended to help accelerate conservation of our lands and coastal waters through voluntary, collaborative action with partners across the state. Five years later, how well has 30X30 met its goals? Join host Ronnie Lipschutz for a conversation about 30X30 with Meghan Hertel, Deputy Secretary for Biodiversity and Habitat at the California Natural Resources Agency, who recently drafted and published the 2025 annual progress report on 30x30, in coordination with the Go...
