After decades of restoration, recent Chinook salmon runs in Putah Creek have reached 1,800, producing young that swim toward the ocean by the tens of thousands. But, says Putah Creek streamkeeper Max Stevenson, this growing population still faces considerable obstacles. Putah Creek flows from headwaters in the North Coast Ranges to the Toe Drain of the Yolo Bypass, and was dammed near Winters in the 1950s to divert water for Solano County. Salmon began coming to the creek after settlement of a lawsuit in the year 2000 that stipulated releasing water for fish as well as optimizing spawning grounds. Salmon need loose gravel to dig spawning pits, or redds, that are up to six feet across. “They flop over and...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
The success of a restoration project is in the eye of the beholder. Take the recently revitalized salt marsh edging Drift Creek in Alsea Bay, Oregon. To ecologists, the sight of new channels winding through bare, brown mud is a thing of beauty, heralding the abundance of life to come, from sedges and rushes to fish and shorebirds. But, as researchers learned while speaking with people living nearby, not everyone shares this view. Some locals favored the unrestored side for its lush green vegetation and vistas of grazing elk. Resolving such differences in perception is key to local support, which can be required for project funding and permitting. “Restoration can look unsightly at first,” said UC Davis salt marsh ecologist...Read More
Jessica Rudnick’s first love was earth science. But after discovering that people’s beliefs and behaviors were key to solving environmental problems, she fell for social science. Now, as the California Sea Grant extension specialist for the Delta, Rudnick is working to better integrate local people into plans for the region. Understanding the needs of people who live, work, and recreate in the Delta could make the difference between fixes that are rejected or embraced. Delta planning has historically focused largely on ecological health. But, like many estuarine areas, the Delta is a lived-in landscape. “There are socially embedded challenges that play out in environmental issues,” she says. “You can’t just throw more data and research at a problem and think...Read More
In just a few years, tracking the West Coast’s atmospheric rivers by airplane has gone from what one hydrologist called “really wild-eyed stuff” to a Congressionally-funded operation. This Atmospheric River Reconnaissance program, which wrapped up its latest season in March, monitors these increasingly powerful storms as they shoot across the Pacific Ocean and delivers real-time data to National Weather Service forecasters. Knowing when, where, and how hard atmospheric rivers will hit is vital to ensuring water supplies and avoiding floods. “California can swing from 20 inches to 60 inches of rainfall per year,” says Atmospheric River Reconnaissance lead Marty Ralph, a research meteorologist at Scripps Institution of Oceanography. “We’re very different from the rest of the country — that’s why...Read More
On a mild day between rainstorms in mid-December, wildlife biologists outfitted in rubber boots and orange lifejackets load drum after drum of precious cargo onto a small boat docked in Rio Vista, a town on the Sacramento River in the Sacramento-San Joaquin Delta. There is little fanfare but the occasion is nonetheless momentous. The shiny silver drums contain thousands of Delta smelt — finger-size imperiled fish unique to the Delta — that were raised in a conservation hatchery. Today marks the inaugural release of captive smelt into the cold, murky waters of their native home. “For the first time, we’re seeing if it’s possible for hatchery-raised Delta smelt to be released into the wild, survive, and successfully reproduce,” says Katherine...Read More
Mountains are the foundation of water in the western United States, natural infrastructure that captures snowfall during the winter and releases snowmelt over the spring and summer. In California, the snowpack holds nearly as much water on average as all the reservoirs put together, effectively doubling the state’s surface storage. But, as the world warms, we may not be able to rely on this ecosystem service much longer. A new study projects that snowpack shrinkage will likely disrupt the West’s water system well before the end of the century. This finding adds urgency to water managers’ efforts to adapt to climate change. “This is not a problem for later,” says Michael Anderson, state climatologist at the California Department of Water...Read More
Nitrogen inputs to the San Francisco Bay are among the highest of estuaries worldwide, yet so far have not caused harmful impacts like extreme algal blooms, oxygen depletion, and fish kills. But resistance to this nutrient may not last. Ever since the Gold Rush, excess sediment from pulverized rock has been pouring into the Bay, clouding the water and keeping algae in check by blocking sunlight. Recently, however, that protective sediment has diminished in parts of the Bay, contributing to concerns over nutrient pollution. A new study on a natural nitrogen-removal process is key to predicting whether nitrogen will cause ill effects here, too. The Bay’s nitrogen comes primarily from sewage and, for the most part, this nutrient is not...Read More
By the time California finally began regulating groundwater use in 2014, most of the San Joaquin Valley was in critical overdraft. The Public Policy Institute of California estimates that groundwater pumping in the region has exceeded replenishment by an average of 1.8 million acre-feet per year over the last few decades. This imbalance was even worse during our last drought, when overuse shot up to 2.4 million acre-feet per year. Overpumping puts groundwater aquifers at risk of compaction, permanently reducing their water storage capacity and making surface lands sink. Now, however, San Joaquin Valley groundwater managers must find and implement a fix. The state’s Sustainable Groundwater Management Act mandates balancing the region’s pumping with replenishment by 2040. Managed aquifer recharge...Read More
While a supermajority of Americans finally believe we are warming the world, a 2020 Yale Climate Opinion survey shows that most people still aren’t very worried about it. “Climate change is abstract to them,” says UCLA climate scientist Daniel Swain. “They don’t connect it to their personal lives.” But Californians do. Reeling from a decade of record-shattering drought, heat waves, and wildfires, people in the Golden State overwhelmingly tell Public Policy Institute of California pollsters that the effects of global warming have already begun. Indeed, Swain confirms, researchers can now link climate change with some of today’s extreme events beyond a reasonable doubt. “Climate change is a slow process, it kind of sneaks up on you, but we’re at the...Read More
“There’s no way we can manage them for recovery if we don’t understand the biological processes that govern their dynamics through time and space,” says UC Santa Cruz/NOAA salmon expert Flora Cordoleani, lead author of a study reported in the December 2020 issue of San Francisco Estuary and Watershed Science. Cordoleani and colleagues identified the monitoring gaps while building a model of the spring-run Chinook life cycle. The model accounts for three self-sustaining populations of these at-risk fish, assessing survival of key life stages (eggs, fry, smolts and adults) as well as in key habitats (natal creeks, the Sacramento River, floodplains in the Sutter and Yolo bypasses, the Sacramento-San Joaquin Delta, and San Francisco Bay). “It’s a complex model, and...Read More
“They don’t represent current operations,” says Ukiah-based consultant Andrew Jahn, lead author of the analysis reported in the September 2020 issue of San Francisco Estuary and Watershed Science. Current operations at the State Water Project (SWP) and the Central Valley Project (CVP) can reverse flows in the Old and Middle rivers, diverting salmon on their way to the ocean towards the projects. Existing salmon loss estimates also fail to account for a likely Old River hotspot for predators, drawn to the influx of salmon and other fish near the two water projects. Evidence of this hotspot lies in the numerous acoustic tags from young salmon to be found in the sediment, which were presumably defecated by striped bass, as well as...Read More
In 2012 a team of salmon researchers tried a wild idea: putting pinky-sized Chinook on a rice field in the Yolo Bypass, a vast engineered floodplain designed to protect the city of Sacramento from inundation. The team found that rearing fish on farms works better than they had ever dreamed.Read More
Valley groundwater pumping is calculated as the total water demand minus surface water deliveries. However, today’s water model relies on individually reported diversions across the entire valley, and compiling all these data is a slow process; by the time the numbers are crunched, assessments of groundwater use are already outdated. “It can take years,” says Jordan Goodrich of University of Waikato in New Zealand. “It’s one of the biggest problems we face in tracking the Central Valley water budget.” Overdrafting groundwater can cause subsidence, permanently reducing the storage capacity of aquifers as well as jeopardizing above-ground infrastructure that delivers water and controls flooding. In the March 2020 issue of San Francisco Estuary and Watershed Science, Goodrich and colleagues at Scripps...Read More
When heavy rains coincided with an extreme high tide in 2005, water from the Carquinez Strait overtopped flood protections in the City of Benicia. Making matters worse, the high seas also submerged stormwater outfalls. Water backed up stormdrains, inundating historic homes and small businesses. As tides keep rising, scenarios like this will play out more often―and with greater severity―along the Solano County shoreline.Read More
In 2017, a perfect storm hit the City of San Jose in Santa Clara County. Coyote Creek, which winds through the heart of the city, overtopped its banks, flooding businesses and hundreds of homes up to depths of six feet. Thousands of people were evacuated and property damages exceeded $70 million. “If I’ve learned anything in my 25 years here, it’s that you have to give creeks room to move, which also creates more resilience to climate change,” says Valley Water's Afshin Rouhani...Read More
Corte Madera creek is an outsized problem for people in Ross and other towns built right up to its banks. “Our peaceful creek turns into a rushing torrent in winter,” says Chris Martin, who grew up in the small Marin County town. Finding a fix has been contentious since 1971, when the U.S. Army Corps of Engineers put a mile-long concrete flood control channel through Ross.Read More
Paul Detjens is driving us from his Martinez office to a restoration site near the mouth of Walnut Creek on Suisun Bay, a project he spearheads as an engineer for the Contra Costa County Flood Control District. These lower reaches of the creek — straightened, widened, and leveed by the U.S. Army Corps of Engineers — have been a sluggish, silt-filled problem for more than half a century. Detjens has worked to find a solution for the last 17 years. Now that the district has taken the unusual approach of parting ways with the Corps in favor of local control, a fix is finally in sight. Goals include protecting people from floods, restoring habitat, reconnecting the creek with its historical...Read More
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.
