Adam Henderson spreads out an atlas with colorful pages on the closed trunk of his white sedan. It’s an early morning in February and the sun is just high enough to start burning off a blanket of fog that’s settled among the nearby willows and cottonwoods. Behind us, across a gravel parking lot, is a gate that’s an access point for the Sacramento River National Wildlife Refuge, controlled and maintained by the U.S. Fish and Wildlife Service. On the other side of the gate, a couple hundred yards of flat field ends in a 20-foot drop that acts like a well-defined shoulder for the river—and it’s the reason why we are standing here. Thanks to January’s heavy rains, the river...Read More
When a team of fish biologists was tasked with restoring spring-run Chinook salmon in the San Joaquin River in 2006, none of them quite knew where to begin. The riverbed had been parched for so long that someone even built a house in it. The salmon that once thronged up-river by the hundreds of thousands had vanished, and there was no precedent for jumpstarting a population from scratch.Read More
When the storm hit, it was lucky that my parents had a habit of leaving one car on each side of the Carmel River as they commuted from Big Sur into Monterey each day. The 1995 El Niño rainfall had pushed the Carmel River into hundreds of homes, and destroyed the Highway 1 bridge that connected Big Sur with the rest of the world. Most Big Sur residents were trapped during the week it took the Federal Emergency Management Agency (FEMA) to repair the freeway bridge. But in the era before Zoom, my mother couldn’t just stay home from nursing school. So my parents trekked past the mud of submerged artichoke fields on the river’s south bank and onto the...Read More
In the mountains and foothills of California, an enduring drought has depleted the state’s major reserves of water. There is virtually no snowpack, and most of the state’s large reservoirs are less than 40 percent full. But in the central Sierra Nevada, a trio of artificial lakes remain flush with cold mountain water. The largest of them, Hetch Hetchy Reservoir, from which millions of Bay Area residents receive water, is more than 80 percent full. This remarkable plentitude is the outcome of careful planning by the agency that manages the Yosemite National Park reservoir plus conservation by Bay Area residents, who use less water per capita than most other people in the state—between 35 and 65 gallons per person per...Read More
As a source of flowing water, upper Coyote Creek is unreliable at best. Though storms swell its banks in winter, Mediterranean-climate summers shrink this South Bay stream to a series of isolated pools by August. “By October right before the rains come, we’re down to these really small pools that have all the fish in them,” says retired U.S. Environmental Protection Agency ecologist Rob Leidy. Leidy and UC Berkeley fish ecologist Stephanie Carlson began monitoring the annual dry-down of upper Coyote Creek in 2014, with the help of Hana Moidu and other graduate students. The creek itself originates in Henry W. Coe State Park and flows to the Bay through Coyote and Anderson lakes south of San Jose. The scientists...Read More
A 90-year-old Australian lungfish at San Francisco’s Academy of Sciences has received a lot of press lately, but there is a wild fish species living in the San Francisco Bay that has the potential to live that long or longer — or so we think. While one white sturgeon caught in the Columbia River Basin was estimated to be 104 years old, the life expectancy of white sturgeon, Acipenser transmontanus, which includes the Central Valley population endemic to the San Francisco Bay, is hard to pin down. “There are old ones out there, but it’s really hard to give a number because we just don’t have it,” says John Kelly, statewide sturgeon coordinator for the California Department of Fish and...Read More
For more than two decades, steelhead — listed as federally threatened in 1997 — have been monitored throughout the state. However, until recently that monitoring has been a haphazard affair. Each local jurisdiction has established a different system, using different methods with different degrees of intensity, according to a 2018 study examining monitoring within the Central Valley and its environs. In some areas, primarily the Sacramento River watershed, which drains the vast northern part of the valley, data has been collected more comprehensively. In other areas, such as the San Joaquin River system to the south, more gaps remain. And in general, monitoring tended to focus solely on migrating numbers and not more detailed life history demographics. “We need to...Read More
Such practices also hasten the destruction of an important and dwindling habitat. Melissa Rohde of the State University of New York College of Environmental Science and Forestry (SUNY-ESF) and colleagues analyzed five years of high-resolution satellite and water resource data showing vegetation greenness along California rivers. Trees growing alongside the 30 percent of state rivers with natural flows decreased in greenness from the wet spring through the dry summer months, the scientists report in the Proceedings of the National Academy of Sciences, demonstrating they rely on groundwater to make it through the dry season. By contrast, woodlands along the 70% of streams receiving water from dams, wastewater treatment plants, and other human sources kept up the same vigorous levels of...Read More
Much like when tech money reshapes an historical neighborhood, a beaver’s move downtown can cause the locals to worry. In Napa, the animals’ sprawling waterfront complexes create worrying pools along the riverbank, while the native cottonwoods are whittled down and threaten landowners’ roofs. It seems destined that two species known for their environmental engineering would struggle to live in unison. However, municipalities like Napa and Martinez in Contra Costa County have learned to live with their beavers, and the upcoming California Beaver Summit aims to set the record straight. “Our approach is hands-off,” says Jeremy Sarrow, a resource specialist with Napa County Flood Control and Water Conservation District, describing the county’s tack toward managing beaver dams built along inhabited waterfronts....Read More
Historically, most fish passages have been designed to help native salmon return to their upstream habitat and spawning grounds, with little consideration for other migrating species such as sturgeon and lampreys. “There is an assumption that if you just build a fish passage structure, fish will go thorough it, but that is not always the case,” says Department of Water Resources fisheries biologist Zoltan Matica, who conducted the review. “The challenge is to understand that this isn’t only a physical barrier, it can be also a mental barrier.” For example, some species that engage in schooling behavior, such as shad, may refuse to even enter a structure if it limits them to passing one at a time. According to the...Read More
In most respects, Marin County is a privileged place. But its miles of Bay and ocean shoreline and many low-lying towns, positioned to afford easy coastal access and world-class scenery, represent a major liability in the era of sea-level rise. “Marin is the canary in the coal mine in some ways, because almost everything is in that narrow strip along the Bay,” says Roger Leventhal, a senior engineer with Marin County Public Works.Read More
In 2002, more than 70,000 adult salmon died on the Klamath River when U.S. Bureau of Reclamation diversions caused water temperatures to spike. In February, the Klamath River Renewal Corporation, including the Yurok and Karuk Tribes, filed to take over management of four hydroelectric dams in the upper watershed. “There’s never been a project that has considered removing four dams at the same time on the same river...Read More
Statewide, 13,000 miles of levees disconnect our rivers from their floodplains, which once served as nurseries for young salmon migrating to the ocean. California Natural Resources Secretary Wade Crowfoot wants to help restore this connection: “It’s a win-win-win―it’s a way we can reconnect water with land, create habitat, and provide flood protection.”Read More
It was the culmination of a long struggle for the Jackson-based Foothill Conservancy and other river advocates. Four years ago, a Mokelumne bill was approved by the state Senate but killed by a parliamentary maneuver that blocked a vote in the Assembly. Despite significant support in Calaveras and Amador counties, the bill was opposed by local water agencies concerned about the potential impact on their water rights. In 2015 Assemblyman Frank Bigelow (R-O’Neals) successfully proposed a state study of the Mokelumne’s suitability for wild and scenic designation. The resulting California Natural Resources Agency report, released in April, recommended protected status with special provisions ensuring water agencies’ existing rights and ability to apply for new rights. “All of the affected water...Read More
A levee replacement project near the small town of Hamilton City is breaking ground as the first project that the US Army Corps of Engineers has approved based in part on potential benefits to an ecosystem. “We’ve been told this will be a national model once it’s completed,” says Lee Ann Grigsby of Hamilton City. The levee, whose original construction failed to meet modern standards, had needed to be fixed for a long time: recent estimates gave it only a 66% of withstanding a 10-year flood scenario. In 2002, new Army Corps guidelines permitted ecosystem benefits to be taken into the accounting of costs and benefits. Today, one section of the levee has been completed and restoration of the newly...Read More
In 2002, when stretches of the Napa River running through Rutherford area vineyards breached levees and flooded yet again, Michael Honig did something remarkable: rather than call the authorities to complain, his neighbors and he banded together to restore their riverbanks. “It had became a kind of competition,” Honig says.Read More
The 2017 update to the Central Valley Flood Protection Plan, to be released later this summer, radically revises the flood control strategies that have prevailed for more than a century. The plan recognizes the connections between the flood system, the water system and the ecosystem, and relies less on levees and more on floodplain restoration to upgrade the state’s aging and inadequate flood control infrastructure.Read More
Remember that chart showing how a bill becomes a law in your high school civics textbook—all those boxes and arrows? Odds are it didn’t include the Suspense File of the Assembly Appropriations Committee, a legislative limbo where bills can expire without ever coming to a vote. That was the fate of Senate Bill 1199, a measure introduced by State Senator Loni Hancock (DBerkeley) in April to add portions of the Mokelumne River to the California Wild and Scenic Rivers System. Supported by Friends of the River, the Foothill Conservancy, and the Calaveras County Board of Supervisors, SB 1199 cleared the Senate in May. In the Assembly, Appropriations Chair Mike Gatto referred the bill to the Suspense File because of its alleged fiscal...Read More
Hothouse Earth

Nothing could be stranger than sitting in the dark with thousands of suits and heels, watching a parade of promises to decarbonize from companies and countries large and small, reeling from the beauties of big screen rainforests and indigenous necklaces, and getting all choked up.
It was day two of the September 2018 Global Climate Action Summit in San Francisco when I felt it.
At first I wondered if I was simply starstruck. Most of us labor away trying to fix one small corner of the planet or another without seeing the likes of Harrison Ford, Al Gore, Michael Bloomberg, Van Jones, Jerry Brown – or the ministers or mayors of dozens of cities and countries – in person, on stage and at times angry enough to spit. And between these luminaries a steady stream of CEOs, corporate sustainability officers, and pension fund managers promising percentages of renewables and profits in their portfolios dedicated to the climate cause by 2020-2050.
I tried to give every speaker my full attention: the young man of Vuntut Gwichin heritage from the edge of the Yukon’s Arctic National Wildlife Refuge who pleaded with us not to enter his sacred lands with our drills and dependencies; all the women – swathed in bright patterns and head-scarfs – who kept punching their hearts. “My uncle in Uganda would take 129 years to emit the same amount of carbon as an American would in one year,” said Oxfam’s Winnie Byanyima.
“Our janitors are shutting off the lights you leave on,” said Aida Cardenas, speaking about the frontline workers she trains, mostly immigrants, who are excited to be part of climate change solutions in their new country.
The men on the stage, strutting about in feathers and pinstripes, spoke of hopes and dreams, money and power. “The notion that you can either do good or do well is a myth we have to collectively bust,” said New Jersey Governor Phil Murphy whose state is investing heavily in offshore wind farms.
“Climate change isn’t just about risks, it’s about opportunities,” said Blackrock sustainable investment manager Brian Deese.
But it wasn’t all these fine speeches that started the butterflies. Halfway through the second day of testimonials, it was a slight white-haired woman wrapped in an azure pashmina that pricked my tears. One minute she was on the silver screen with Alec Baldwin and the next she taking a seat on stage. She talked about trees. How trees can solve 30% of our carbon reduction problem. How we have to stop whacking them back in the Amazon and start planting them everywhere else. I couldn’t help thinking of Dr. Seuss and his truffala trees. Jane Goodall, over 80, is as fierce as my Lorax. Or my daughter’s Avatar.
Analyzing my take home feeling from the event I realized it wasn’t the usual fear – killer storms, tidal waves, no food for my kids to eat on a half-baked planet – nor a newfound sense of hope – I’ve always thought nature will get along just fine without us. What I felt was relief. People were actually doing something. Doing a lot. And there was so much more we could do.
As we all pumped fists in the dark, as the presentations went on and on and on because so many people and businesses and countries wanted to STEP UP, I realized how swayed I had let myself be by the doomsday news mill.
“We must be like the river, “ said a boy from Bangladesh named Risalat Khan, who had noticed our Sierra watersheds from the plane. “We must cut through the mountain of obstacles. Let’s be the river!”
Or as Harrison Ford less poetically put it: “Let’s turn off our phones and roll up our sleeves and kick this monster’s ass.”
4th California Climate Change Assessment Blues
by Isaac Pearlman
Since California’s last state-led climate change assessment in 2012, the Golden State has experienced a litany of natural disasters. This includes four years of severe drought from 2012 to 2016, an almost non-existent Sierra Nevada snowpack in 2014-2015 costing $2.1 billion in economic losses, widespread Bay Area flooding from winter 2017 storms, and extremely large and damaging wildfires culminating with this year’s Mendocino Complex fire achieving the dubious distinction of the largest in state history. California’s most recent climate assessment, released August 27th, predicts that for the state and the Bay Area, we can expect even more in the future.
The California state government first began assessing climate impacts formally in 2006, due to an executive order by Governor Schwarzenegger. California’s latest iteration and its fourth overall, includes a dizzying array of 44 technical reports; three topical studies on climate justice, tribal and indigenous communities, and the coast and ocean; as well as nine region-specific analyses.
The results are alarming for our state’s future: an estimated four to five feet of sea level rise and loss of one to two-thirds of Southern California beaches by 2100, a 50 percent increase in wildfires over 25,000 acres, stronger and longer heat waves, and infrastructure like airports, wastewater treatment plants, rail and roadways increasingly likely to suffer flooding.
For the first time, California’s latest assessment dives into climate consequences on a regional level. Academics representing nine California regions spearheaded research and summarized the best available science on the variable heat, rain, flooding and extreme event consequences for their areas. For example, the highest local rate of sea level rise in the state is at the rapidly subsiding Humboldt Bay. In San Diego county, the most biodiverse in all of California, preserving its many fragile and endangered species is an urgent priority. Francesca Hopkins from UC Riverside found that the highest rate of childhood asthma in the state isn’t an urban smog-filled city but in the Imperial Valley, where toxic dust from Salton Sea disaster chokes communities – and will only become worse as higher temperatures and less water due to climate change dry and brittle the area.
According to the Bay Area Regional Report, since 1950 the Bay Area has already increased in temperature by 1.7 degrees Fahrenheit and local sea level is eight inches higher than it was one hundred years ago. Future climate will render the Bay Area less suitable for our evergreen redwood and fir forests, and more favorable for tolerant chaparral shrub land. The region’s seven million people and $750 billion economy (almost one-third of California’s total) is predicted to be increasingly beset by more “boom and bust” irregular wet and very dry years, punctuated by increasingly intense and damaging storms.
Unsurprisingly, according to the report the Bay Area’s intensifying housing and equity problems have a multiplier affect with climate change. As Bay Area housing spreads further north, south, and inland the result is higher transportation and energy needs for those with the fewest resources available to afford them; and acute disparity in climate vulnerability across Bay Area communities and populations.
“All Californians will likely endure more illness and be at greater risk of early death because of climate change,” bluntly states the statewide summary brochure for California’s climate assessment. “[However] vulnerable populations that already experience the greatest adverse health impacts will be disproportionately affected.”
“We’re much better at being reactive to a disaster than planning ahead,” said UC Berkeley professor and contributing author David Ackerly at a California Adaptation Forum panel in Sacramento on August 27th. “And it is vulnerable communities that suffer from those disasters. How much human suffering has to happen before it triggers the next round of activity?”
The assessment’s data is publicly available online at “Cal-adapt,” where Californians can explore projected impacts for their neighborhoods, towns, and regions.
