  • Prophets of the Finite: Remembering Paul Ehrlich, Ronny Davis, and Wendell Berry

    From L to R: Ann Ehrlich, Amory Lovins, Dr. Paul Ehrlich, and David Kupfer, having lunch in Palo Alto in 2022

    By David Kupfer

    The summer of 2026 has witnessed the quiet, heavy closing of an era. With the recent passings of population biologist Paul R. Ehrlich, radical theater pioneer R.G. “Ronny” Davis, and most recently, the visionary agrarian writer Wendell Berry on August 31, we have lost a singular trinity of American defiance. Operating in vastly different arenas—the university laboratory, the public park, and the rural hillside—these three men were bound by a shared, ferocious commitment to shaking humanity out of its industrial complacency. To have known them as friends and mentors over the decades was to witness the rare alchemy of brilliant intellect wedded to an uncompromising moral compass. Now, as the dust settles on their long lives, their final, intimate moments reveal the heavy burden borne by those who dare to speak truth to a civilization bent on its own consumption.

  • In CA04, which Eric Jones do you get?

    Wrong Seat, Wrong Moment – Part V

    By Judy Tipple

    Yesterday in Marysville, Eric Jones stood in front of 250 farmers at the Yuba-Sutter Farm Bureau forum and said this:

    “Let me make a simple statement: no more data centers in California.”

    He called for a national moratorium. He said members of Congress who don’t understand the technology shouldn’t be in the room for these decisions (Patch, Sept. 2, 2026).

    Strong stuff. The kind of line that gets applause in a room full of people watching data centers drink their water and eat their farmland, and farmland all over the country.

    Here’s the problem. It’s not what his campaign has been telling voters for months.

    Go to ericjones.us right now. His official AI platform page said something very different, until 2 days ago:

  • Give Yourself a $200 Pay Raise

    By Bertie Brouhard

    It may be more. Might be less. But it’s monthly and this is a raise of after income tax dollars. Most living dwellers, bill payers, are eligible. Those incredibly wealthy, not even slightly cost conscious, a few living off the grid or your neighbor perhaps who has recently invested a large sum in solar panels, lithium battery banks and highly efficient mechanical systems might not be. My  target audience for this article is the rest of you.

    We live in a meteorological wonderland; this huge valley with its high desert, dry heat climate. Thankful every summer evening for our refreshing delta breeze. And our frost, snow free winters. As I type this about 9 AM it’s bright and still on this late August morning. Outside air temp is 68F and it’s 66F in my living room. Last night’s low was 58F and today’s high is 93F. My predicted indoor high is 78F. Only my laptop, my fridge and the trickle charges (TV and smart speakers) are consuming any electrical energy.

    Your pay raise is generated by the cost saving measures you implement to drastically lower your P, G & E monthly devotional, offering, bequest, and irksome payment.

  • Why an Unubstructed Delta Breeze Is Critical for California

    And how the proposed California Forever project threatens livability in Davis and other parts of the Central Valley

    By Dr. Glen Holstein

    Covering 18,000 square miles, California’s Central Valley is the largest nearly flat valley on earth.  It is almost entirely surrounded by mountains and consequently prone to very high temperatures since winds blowing downhill from mountains compress and heat air.  That is why Death Valley, completely surrounded by mountains, has average July temperatures higher than those of any month anywhere else on earth.  Its mean July temperature is 100.9 degrees F while the mean July temperature of Aswan deep in the Sahara Desert but not surrounded by mountains is 91.8 degrees F.  Death Valley even set the all-time scientifically accepted high temperature record of 134 degrees F in 1913.

    But the Central Valley is not entirely surrounded by mountains.  They open up at the Golden Gate to permit a cooling air flow from the Pacific Ocean called the Delta Breeze to significantly lower summer temperatures in the center of the Central Valley but much less so in its northern part called the Sacramento Valley and its southern part called the San Joaquin Valley. 

    The Delta Breeze’s origin is the cold California Current flowing southward from Alaska.  Disturbance where it encounters obstructions like Point Reyes and the Monterey Peninsula causes upwelling from depths that cool coastal water even more.

  • Our Revolution seems to have quietly rescinded its endorsement of Eric Jones

    They should state their un-endorsement explicitly and explain their reasons for it

    By Roberta Millstein

    As I documented in a past article, Eric Jones is not a progressive.  Now it seems that Our Revolution, which Wikipedia calls “an American progressive political action organization founded as a continuation of Senator Bernie Sanders’s 2016 presidential campaign,” has finally figured out the same thing.  Having previously endorsed Eric Jones in his run to unseat Mike Thompson in CA-04, Our Revolution seems to have quietly withdrawn that endorsement.

    I want to be clear: this is not a critique of Our Revolution. I consider myself to be a progressive and I generally support their mission. I contributed to Bernie Sanders’s presidential campaigns, voted for him twice, displayed the swag. But organizations can make mistakes.  So it is no surprise to me that they would withdraw their endorsement once that they had the complete picture of who Jones is.

  • Eileen’s Update

    No on Measure V Campaign Gratitude

    The No on Measure V campaign would like to express our sincere gratitude to the many Davis voters who voted to reject the Village Farms proposal for the many reasons we explained in our articles, literature, and online at our NoOnMeasureV.org website.

    It is unfortunate that this project divided the community, but ultimately, the majority of voters understood that the project was unacceptable due to its many impacts, including toxics, flooding potential, massive traffic, enormous infrastructure costs, habitat destruction along Channel A, as well as endangerment of the vernal pools and the endangered species of Vernal Pool Tadpole Shrimp, and especially due to the unaffordable market-rate housing and the seriously inadequate affordable housing plan. The housing proposed would have been unaffordable to parents of young kids and would not have yielded hundreds of kids, and the and the long timeline of at least 15+ years did not coincide with the School District timeline, so it would not have helped the schools.

    This issue is now behind us, and hopefully we can come together as a community and work on solutions instead of school closures. This process needs to start now, and the School Board needs to move forward and approve the formation of a parent-based subcommittee, as recommended by California Best Practices, to work on solutions with the School District to avoid school closures without delay.

  • It’s Right There In Your Backyard

    By Bertie Brouhard

    Yes. Your backyard; figuratively and maybe literally. Some reading this may not have a backyard. Most with a family unit I suspect do. But like mine it’s California and rather small and fenced in. It might have a pool; likely not. But certainly it has possibilities for some summer fun; perhaps badminton, ping pong,  croquet, your hacky sack, horse shoe or cornhole area or an archery (yikes) range. In my youth I tried it all including a makeshift baseball batting cage that did not even slightly improve my hitting.

    As for your family I envision two parent figures and two youngsters and while I encourage everyone to read on, this column has these four in mind.

    One of my granddaughters once asked me “Were you ever four?” She was curious. I must have looked ancient to her. I smiled and told her it’s a wonderful age. About that time 1950 C.E. or so mine and other parents of my buds let us sleep outside in someone’s backyard on warm, humid, star studded Nebraska summer nights. I don’t recall tents but remember the many mosquitoes, the sound of UP freight trains and back porch lights and our flashlights. Feigning sleep around ten I suppose we were off on our bikes roaming the many streets, parks, construction sites and gardens in our small town. We knew where the best melons, apples, rhubarb and strawberries could be picked and where others; especially girls our age, might join us for our jaunts. It all went well until our neighbor, the ever vigilant spinster, Mrs. Pierceson, ratted us out. She caused a month’s pause in our adventures, having told my dad, “I saw your son and a couple of his “ruffian” friends downtown last night. (Just what is a “ruffian?”)

  • Award-Winning Climate Action and Adaptation Plan (CAAP) Presented July 7th

    By Scott Steward

    Kristen Wraithwall is the Manager of the Sustainability Division. The Sustainability Division operates within the Health and Safety Department of our Yolo County. Kristen will present the Update on Climate Action and Adaptation Plan (CAAP) Implementation Progress at this Tuesday’s (July 7th) Yolo County Board of Supervisors Meeting at 9:00 AM.

     Zoom meeting: By PC: https://yolocounty.zoom.us/j/84359964086

    Kristen, her staff, the Climate Action Commission, and the County have made consistently strong progress in climate action despite very difficult budget circumstances. This Sustainability work continues to provide our county with grant-funded programs that Yolo County cities and other California counties look to as models for what can be accomplished in their own jurisdictions. Yolo County’s Climate Action and Adaptation Plan received the Sacramento Valley Section APA Award of Excellence in Resilience and Sustainability (May 2025) and the Beacon Award from the Institute for Local Government (November 2025). 

    Vehicle use remains the #1 source of greenhouse gas emissions in Yolo County, so it is no surprise that 2026-2027 CAAP priorities emphasize transportation, including the implementation of countywide Zero-Emission Vehicle (ZEV) programs. Transportation is followed by building energy efficiency in coordination with Valley Clean Energy, Natural & Working Lands water conservation and carbon soil enhancement, recycling, and public cooling infrastructure.

  • Living Water, Living Knowledge: Youth Explore Indigenous Stewardship in the Yolo Basin

    (From press release) For thousands of years, Patwin-Wintun peoples cared for the wetlands and waterways of the Yolo Basin using stewardship practices that enhanced biodiversity and sustained one of California’s richest delta ecosystems. This summer, Native, BIPOC, and ally youth are invited to experience these teachings firsthand through the Traditional Ecological Knowledge (TEK) Youth Program.

    Led by Wintun/Maidu educator, naturalist, Fire Boss, and cultural practitioner Diana Almendariz, participants will explore how Indigenous communities lived in relationship with the land, plants, animals, and living water. Through hands-on activities, youth will learn about tule gathering, cultural burning, wetland ecology, wildlife, traditional foods, and Indigenous approaches to environmental stewardship.
