A small but mighty wetlands project on the San Rafael waterfront is moving forward thanks to a $1 million planning and design grant from the San Francisco Bay Restoration Authority.
Restoration of the heavily eroded 20-acre Tiscornia Marsh at the mouth of the San Rafael Canal will use dredged sediment to create new habitat for the endangered Ridgeway’s rail and salt marsh harvest mouse, migratory shorebirds, and other marsh species. Meanwhile, improvement of an adjacent levee will enhance public access along a levee-top section of the Bay Trail and, perhaps most critically, provide flood protection for the nearby Canal District, a dense, low-income community that’s home to many Latino immigrants...Read More
A new study by United States Geological Survey researchers examines how future coastal storms and waves will affect California’s shoreline via erosion and flooding in conjunction with sea-level rise. And it puts numbers on the cost and people affected by California’s future storms and waves: about $150 billion in property and 600,000 people by 2100. “Bay Area communities account for two-thirds of the projected impacts across the state over the next century,” explains lead author Patrick Barnard. “Many communities, such...Read More
By Michael Hunter Adamson Malea G., a fourth grader in Mr. Moore’s class at Bayview’s Malcolm X Academy Elementary School, shows me her Tower of Power. It’s a wooden, trapezoidal structure roughly two feet high and decorated with stickers naming personal qualities she’s proud of. I ask her which of these she might turn to when dealing with climate change. “Leadership,” Malea answers after a brief pause. “If there was a flood, someone would need to take charge.” Working in...Read More
In the early days, when the wetland protection and restoration landscape was less complex, the JV “could be everywhere and do everything.” Now it needs to be more strategic. “I’m a listener, a synthesizer, and I’m pretty good at herding diverse interests toward shared goals,” says Scoggin, who is taking over the 20-year-old wildlife habitat venture after 16 years in second seat. “The JV is built on deep and lasting relationships,” she says, both awe and pride in her voice....Read More
Joining the Bay Conservation and Development Commission as Program Manager for the Adapting to Rising Tides ( ART) program last November, Brechwald oversees multiple projects assessing coastal areas that are vulnerable to sea level rise. “We’re working at every scale, from the federal level down to community members who will be affected by climate adaptation,” she explains. Brechwald and her team cover the gamut of a community’s assets — from transportation systems to areas set aside for more development or...Read More
“The existential challenge is doing marsh restoration fast enough to get it into place and established before sea level rise really starts to kick in,” says Halsing, the new Executive Project Director for the massive, 15,000-acre South Bay Salt Pond Restoration Project. The thoughtful and reflective restoration manager is seizing the reins from previous director John Bourgeois to lead the 50-year, $1 billion effort that is the largest wetland restoration project on the West Coast. “I had to take a...Read More
“I’ve done the entire spectrum, from the federal to the state to the NGO perspective,” says the incoming CEO of Point Blue, the Petaluma-based nonprofit focused on environmental conservation and research. “This gives me a really good overview on how to best support our work as an organization.” Most recently Oliva was an acting director of the Development Resources and Disaster Assistance Division at the USDA’s Foreign Agricultural Service. His work there focused on climate-smart agriculture projects, such as working...Read More
By Alastair Bland Last year, researches working with SF State’s Estuary and Ocean Science Center installed an array of instruments to track underwater parameters. John Largier, a UC Davis professor of oceanography, says he expects clear trends and patterns indicative of warming and acidifying waters to become apparent in the data in about a decade. With nations making painfully slow progress in reducing their emissions of greenhouse gases, Largier thinks local efforts to boost the resiliency of the Bay ecosystem...Read More
By Lisa Owens Viani In 2016, restoration managers with The Nature Conservancy discovered that western sycamores planted along the Sacramento River had hybridized with the non-native London plane tree. The native sycamore is “kind of a messy tree,” says project manager Ryan Luster. “The branches break off and create cavities that wildlife love to use.” Concerns about the tree’s status first arose in the 1990s when the California Department of Fish and Wildlife found only 17 sycamore stands larger than...Read More
Researchers with the University of California analyzed climate and water-temperature data from 19 lakes scattered throughout the Sierra Nevada, including Emerald Lake in Sequoia-Kings Canyon National Park, where UC runs a long-term study site. They found that summer air temperatures at Emerald Lake are warming 1.5 degrees Fahrenheit per decade — a rate lead author Steven Sadro says is as high as nearly anywhere on the planet. Yet to the researchers’ surprise, says Sadro, an assistant professor of Environmental Science...Read More
Looking east from the levee-top trail, a silvery swath of bay is dotted with low islands -- some tufted with plants, others mere muddy humps that barely break the surface. This is low tide at the nearly 1,000-acre Sears Point wetland restoration project on the western side of San Pablo Bay. The islands, 500 in all, are actually man-made mounds, scattered across the mudflat as an integral part of the restoration design. Each is roughly 60 feet across and was...Read More
A boatload of estuary experts from around the country gathered on an early October day to tour the prettiest part of San Francisco Bay. They paid rather less attention to Alcatraz and the Golden Gate than to each other. In town for the National Estuary Program’s annual Tech Transfer Conference, they had come to compare notes and strategies from the 28 varied bays, bights, bayous, and river mouths that benefit from one of the nation’s most durable, and efficient, environmental...Read More
What makes a bond green? When the debt is issued specifically to bankroll projects with tangible environmental benefits. So when the San Francisco Public Utilities Commission faced a hefty price tag for major infrastructure overhauls, they chose to go green. “The goal is to get to $1 trillion in annual green bond issuances by 2020,” says Mike Brown, the SFPUC environmental manager who oversees the $1.4 billion in green bonds that the commission has issued since 2015. To Brown, the...Read More
Harbor Seals “have this dual existence,” says Sarah Allen, National Park Service ecologist. “They’re tied to the land physiologically and tied to the bay waters for food and travel.” From rocky islets to tidal marshes, the Bay shoreline offers respite to these native marine mammals. Rocky islets like the Castro Rocks, located near the Richmond-San Rafael Bridge, are particularly important refuges -- but more than half the islets that exist throughout the Bay are likely to be erased by sea-level...Read More
For three years, Kyle Hemes of UC Berkeley and colleagues kept tabs on the heat flux and air flow above three restored Delta wetlands on Twitchell and Sherman islands, and an alfalfa field on Twitchell Island. Surface temperatures at wetlands with open water were up to 5.1 degrees Celsius cooler than the crop field during the daytime. As expected, the dark open water absorbed more solar radiation, and released the energy slowly at night. But wetland vegetation played a role...Read More
The plan addresses ocean acidification—like climate change, a consequence of rising atmospheric CO2 levels—in the context of other threats such as polluted runoff, warming temperatures, and rising seas. It promotes local solutions that are likely to provide multiple benefits—from improving water quality to promoting healthy seagrass, marsh, and kelp forest habitats. The plan, one of the first released by a member of the International Alliance to Combat Ocean Acidification, identifies six key strategies, and outlines five-year goals and actions for...Read More
“When you have two hundred of the best climate adaptation professionals in the room together, that’s an opportunity…” said Phoenix Armenta from the Resilient Communities Initiative. Armenta and Lucas Zucker from the Central Coast Alliance United for a Sustainable Economy were members of a special equity-tribal advisory committee convened before the conference to help with program development, diversify attendance, and elevate the conversation on equitable climate adaptation. “There’s always tension about whether to weave [equity] into every single session or give it its...Read More

Salmon once flourished in California despite huge swings in climate – from mega-droughts to massive floods – that were far more extreme than those today. But then people re-engineered the state’s waterways to meet their own needs. “Complexity is what salmon thrive on, and we’ve been making their habitat simpler and simpler,” says biologist Bruce Herbold. “We haven’t been playing to their strengths.” Habitat diversity is key to restoring salmon, and the prospects for restoring Central Valley wetlands to benefit...Read More
“We are seeing events we have never seen before,” said California Natural Resources Secretary John Laird to the over 750 attendees of the California Adaptation Forum on August 28th. Inside the cavernous ballroom of the Sheraton Grand in downtown Sacramento, Laird ticked off to the audience the evidence that climate change is present in California: wildfires burning faster and hotter, rainfall five hundred percent above normal, and longer lasting Central Valley heatwaves. “[Climate change] is happening, we’re experiencing it, and...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. Suess 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.
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.
