California a botanical and climate change hot spot
From coastal redwoods and Joshua trees to golden poppies and sagebrush, California is a global botanical hotspot. It’s also a place confronted with extreme heat, wildfires and crumbling coastlines.
The state’s natural beauty and history of pioneering conservation efforts make it a test bed for protecting biodiversity in the face of current and future climate change, argues a study led by the University of California, Davis.
Published July 29 in Proceedings of the National Academy of Sciences, the study, “Climate Change and California’s Terrestrial Biodiversity,” is part of a special PNAS issue on California sustainability.
The study concludes that California’s 30 x 30 Initiative to preserve 30% of its lands and coastal waters by 2030, along with efforts to harmonize biodiversity conservation and renewable energy, is a promising step. It also highlights the need for California to shift away from its decades-long fire suppression policies and adopt fire strategies reflective of new fire regimes.
“California has had a history for over 100 years of being a leader in protecting the environment—from setting aside parks for people to climate adaptation,” said lead author Susan Harrison, a professor in the UC Davis Department of Environmental Science and Policy. “The threats are extreme and unprecedented, but California has always been a state where creative new solutions have emerged.”
California’s climate has become warmer, drier and more variable since the mid-1900s, the study noted. It examined major threats climate change poses to the state’s biodiversity and sustainability. These include the impacts of shifting plant biodiversity, land-use change, wildfire and renewable energy, and the policy responses to those challenges.
Hot spots on the move
The authors modeled the distribution of about 6,400 native plant species, identifying 15 regional plant biodiversity hot spots—from small areas, such as the Channel Islands, to vast parts of the Sierra Nevada and coastal ranges.
The models indicate these hot spots could lose an average of 19% of their native plant species by 2080 under current climate projections. California’s complex mosaic of microclimates means the state’s species could respond in a wide variety of ways to climate change. Some hot spots are expected to move toward the coast or upslope, while others remain or disappear.
Those stakes help outline the need for renewable energy projects to align with expected biodiversity shifts and needs. For example, Molok Luyuk, or Condor Ridge (formerly Walker Ridge), was slated for wind development projects along its blustery ridge despite its rich biodiversity, before earning protection as part of Berryessa Snow Mountain National Monument.
“This paper is pointing out that we need to be proactive,” said co-author James H. Thorne, a research scientist with the UC Davis Environmental Science and Policy department. “We can’t be reactive like, ‘Oh, this wildfire is out of control. Oh, this species is disappearing. Oh, we misplaced where this green energy site should go.’ We have tools that can be used, some of which we discuss in this paper.”
A new mindset
Wildfire is a nearly year-round reminder of the state’s hotter, drier climate.
The authors write that fire management policies in California are less progressive than its policies for climate and conservation. The paper encourages the state to move away from its longstanding policy of fire suppression and adapt its strategies to use fire as an ecosystem management tool.
State and federal agencies have set ambitious targets to increase the use of fire in land management but have been stymied by bans on prescribed fire motivated by safety and air quality concerns.
Harrison calls wildfire and climate change “game-changers” for how we think about conservation.
“Traditionally, ‘conservation’ had a restrictive meaning—we try to keep things the same. If anything goes missing, we try to put it back,” Harrison said. “But now, we require a different mindset. We need to be willing to modify traditional views of conservation. We need continual innovation.”

California governor’s race tightens as primary day approaches
OAKLAND, Calif. – With Tuesday’s primary election approaching, the race for California governor is coming into focus — and one candidate’s rise has surprised nearly everyone watching.
That’s according to Joe Garofoli, senior political writer and columnist with the San Francisco Chronicle, who broke down the latest polling and key races to watch with KTVU.
Who’s in the lead?
By the numbers:
The latest Berkeley IGS poll of 5,000 likely voters from May 19-24, shows former Attorney General Xavier Becerra leading the field at 25%, with Republican Steve Hilton at 21% and billionaire activist Tom Steyer at 19%.
Just two months ago, Becerra was polling at 5% and Democratic Party leaders were quietly urging lower-performing candidates to reconsider their campaigns. Former Los Angeles Mayor Antonio Villaraigosa, who is now polling at 1%, was among those who suggested Becerra consider dropping out.
“This would be the greatest comeback since Lazarus,” Garofoli said.
He attributed Becerra’s turnaround primarily to the exit of Congressman Eric Swalwell from the race, saying Swalwell’s voters and Becerra share many of the same moderate positions.
Becerra, Garofoli said, has leaned into a steady, reassuring image on the campaign trail.
“He’s sort of portraying himself as Tío Becerra — Uncle Becerra, the kindly uncle,” Garofoli said. “This is not a guy who’s going to go to Sacramento and turn over the tables.”
The other side:
Steyer, meanwhile, has climbed from 15% earlier this month to 19% in the latest poll, powered by $213 million of his own money and a string of endorsements from major progressive organizations in California.
His support for single-payer health care and his pledge to not take corporate PAC money have resonated with the left, even as some progressives have historically been skeptical of billionaire candidates.
“Steyer’s a different type of billionaire than the tech billionaires who they traditionally oppose,” Garofoli said, noting that Steyer’s platform focuses on protecting and creating working-class jobs rather than advancing technologies that could eliminate them.
Ballots are slow coming in
Dig deeper:
Despite the competitive field, Democrats have been slow to return their mail-in ballots, with return rates sitting around 12%.
Garofoli said the hesitation reflects a broader dissatisfaction with the candidate pool.
“I can’t tell you how many people told me, ‘I don’t know who to vote for, none of these people appeal to me,’” he said. “Nobody in this field really has that outsized big personality, or at least has demonstrated it at this point.”
Local perspective:
In San Francisco, former House Speaker Nancy Pelosi added a new variable to the congressional race to fill her seat, endorsing Supervisor Connie Chan over front-runner State Senator Scott Wiener. Garofoli said the endorsement was expected, though its timing surprised him.
Pelosi’s recent endorsement record in San Francisco has been uneven — she backed Dean Preston, who lost, and Joel Engardio, who was recalled — but Garofoli said this one may carry more weight.
“It is for her seat. She has tapped Chan on the shoulder and said, this is the person I want,” he said.
Chan is currently in a tight race with Saikat Chakrabarti, a former tech engineer and one-time aide to Rep. Alexandria Ocasio-Cortez, according to Chronicle polling.
The Pelosi endorsement, Garofoli said, could be enough to push Chan into the top two alongside Wiener.

Steve Hilton on His Surprisingly Strong Bid for California Governor
It’s been quite the unexpected slog through a field of candidates so numerous that all of their names don’t even fit on a single page of the ballot. Democrats in California have held the governor’s mansion, state House, and state Senate for almost two decades and unrest about that trifecta out West is real. The traditional political alliances are frayed, at best, with socialists backing a billionaire and Trump supporting an immigrant. A sex scandal tanked the hopes of a leading candidate, Rep. Eric Swalwell, and Trump’s endorsement of Hilton all but sidelined tough-on-crime Riverside Sheriff Chad Bianco. It’s why Hilton, who moved to California in 2012, is in the mix in a race that is set to test assumptions about party loyalty, candidate partisanship, and money’s power. And it carries massive consequences about who will be the de facto CEO of the fourth-largest economy on the planet, between Germany and Japan, and a major player on the national political stage. This is not some backwater local election.

California just handed oil companies billions in free pollution permits
By Alejandro Lazo, CalMatters
This story was originally published by CalMatters. Sign up for their newsletters.
California air regulators on Friday approved a contentious overhaul of the state’s carbon market, creating a program that could steer billions of dollars in free pollution permits to oil refineries and other major polluters over the objections of environmental groups, key lawmakers and three of the board’s own members.
Ten members of the California Air Resources Board voted to adopt the changes to its cap-and-invest program after two days of lengthy hearings, including a full day dedicated to hundreds of public comments.
The overhaul followed intensive lobbying by the oil industry as well as pressure from Gov. Gavin Newsom’s administration to help keep refineries operating in the state amid rising gas prices.
The approval sets up a potential budget fight in Sacramento. The Legislative Analyst’s Office projects that quarterly auction revenue for state climate programs will drop from roughly $4 billion a year to about $2 billion under the new overhaul.
Such a shortfall would effectively zero out programs lawmakers spent last year fighting to fund: affordable housing, public transit, drinking water in low-income communities and pollution monitoring in California’s most polluted neighborhoods.
The governor’s office praised the measure as a compromise that balanced economic uncertainty with the state’s climate goals. Refinery closures and the Iran-Israel war have driven average California gas prices above $6 a gallon.
Newsom, in a statement, used the moment to draw a contrast with President Donald Trump.
“While Trump sows ongoing chaos and uncertainty, California is staying focused by protecting our economy, safeguarding public health, and doubling down on the clean energy future all Californians deserve,” he said.
Environmentalists warned the changes to the program amount to a giveaway to the fossil fuel industry that weakens California’s only program setting a firm cap on greenhouse gas emissions.
Katelyn Roedner Sutter, California senior director for the Environmental Defense Fund, called the decision “deeply misguided” for prioritizing polluters over communities.
“Newsom’s air regulators are handing billions to oil executives at the expense of our climate, health, and affordability for working families in a rushed process that has shortchanged meaningful public participation,” said Bahram Fazeli, policy director at Communities for a Better Environment.
How the program works — and what changes
California’s 13-year-old carbon market forces major polluters to buy permits while the state lowers the overall cap each year. Friday’s vote will reduce those permits – and creates a new subsidy program carved out of the market.
The program, which may still see changes, could make available a new pool of free pollution permits available to industry valued at as much as $4 billion. Companies that pledge to invest in clean energy and efficiency may qualify for the permits in exchange for investments in clean energy.
The pool will be capped at 118.3 million permits — the same number the air board has said must come off the market for California to hit its 2030 climate target. Environmentalists say the proposal risks wiping out those reductions.
Half are reserved for the fossil fuel sector. A recent Berkeley analysis, by the chair of an independent committee that oversees the carbon market, found refineries could end up with more free permits than they need to cover their emissions.
The air board has defended the design. Officials say the credits will go only to companies undertaking decarbonization projects, will be limited and temporary and can be clawed back if companies misuse them. The plan, they say, is meant to keep California refineries operating at a time of mounting closures and global market pressure. According to air regulators, the amended program will spur clean-energy investment as Trump cuts federal support.
