The naming of boats and ships is a serious matter. Each larger vessel’s name starts with a code that tells what it carries, what propels it, or what purpose it serves. If it were your hobby to keep tabs on traffic on San Francisco Bay, you’d see a lot of big UCCs (container ships) and TCHs and TCRs (tankers). You’d see ferries emblazoned with MV, standing for “motor vessel.” Before COVID-19, you would have spotted the occasional SS, standing for...Read More
Scientists studying environmental pollutants tend to divide them into two distinct groups. One includes “legacy” contaminants that drew attention during the early stages of the environmental movement, like mercury, PCBs, and some pesticides. The other is a much larger class of “emerging” contaminants whose production or monitoring began more recently and about whom less is known; think pharmaceuticals, plastic additives, and flame retardants. Effluent from wastewater treatment plants is often seen as the primary source of emerging contaminants in San...Read More
By Jacoba Charles As many as 30 particles of microplastic smaller than five millimeters in diameter are discharged with every liter of stormwater, according to a report published by the San Francisco Estuary Institute and 5Gyres last October. “A big proportion of what we saw were black rubbery fragments,” says SFEI’s Diana Lin, a lead author of the report. Apart from these likely biproducts of tire wear and tear, hair-like threads of fiber were the other main type of microplastics...Read More
By Cariad Hayes Thronson In March the San Francisco Estuary Partnership released its Wetlands Regional Monitoring Program Plan, which lays out the science framework for a long-term program to monitor tidal wetlands around the Bay. “The focus of the plan is how we’re going to answer five guiding questions about the status and trends of our tidal wetlands,” says the Partnership’s Heidi Nutters. The framework is only the first phase of what will ultimately be a four-year planning process. Nutters...Read More
By Ariel Rubissow Okamoto “BPA is globally detected in human urine,” says scientist Ila Shimabuku of the San Francisco Estuary Institute. BPA, one of a chemical group called bisphenols, is a clear, stable, durable ingredient in plastic bottles, can liners, cash register receipts and many other things we use and touch every day. In 2017, the RMP collected and analyzed 16 bisphenols (including bisphenol A, or BPA) in 22 water samples from around San Francisco Bay. Concentrations of BPA found...Read More
By Alastair Bland The slow, downstream chemical migration of legacy contaminants like mercury and PCBs into the Bay is something that Lester McKee and his colleagues at the San Francisco Estuary Institute hope to cut short. Using funding from the Regional Monitoring Program, they’ve been sampling creeks that enter the central and southern San Francisco Bay for years, identifying the most contaminated waterways. “We want to short-circuit the conveyor belt that delivers the pollutants we’re concerned about into the food...Read More
An interdisciplinary scientist trained in marine ecology, with experience in policy, management, and public outreach, Foley assumed leadership late last year of the Regional Monitoring Program for Water Quality in San Francisco Bay (RMP). Along with overseeing the RMP’s rigorous efforts to study and manage Bay pollutants, Foley who comes to the RMP from New Zealand’s Auckland Council, where she used long-term environmental monitoring data to inform both regional and national management and policy strategies, says she’ll draw on her...Read More
“If you went to the doctor and told them you were taking 69 different pharmaceuticals,” says Emma Rosi of the Cary Institute of Ecosystem Studies, “they would be very concerned with your well-being.” When a study she co-authored detected that number of pharmaceutical compounds in caddisfly larvae along an Australian creek downstream of a treatment plant, it was further evidence that excreted drugs are escaping wastewater facilities and entering food webs. The Bay is no exception. A survey conducted by...Read More
As the “Fish-SMART” signs on local piers warn, the tissues of fish reeled in from San Francisco Bay waters can contain mercury or PCBs, but a new RMP report reminds us of a third contaminant of concern to human health: dioxins. The report, due out in October 2018 and prepared by staff of the San Francisco Estuary Institute and the SF Bay Regional Water Quality Control Board, confirms that while levels of this toxic contaminant in sediments nearshore have declined...Read More
“Small sensors are the foundation of big science,” says Phil Trowbridge, director of the Bay’s Regional Monitoring Program which has just released a new synthesis report on sediment science. The report, combining the results of eight bodies of work, yielded some surprises concerning how much sediment moves from the Sierra and Bay watersheds to the Golden Gate. “The system is calming down after two huge disruptions,” says David Schoellhammer of the U.S. Geological Survey, referring to hydraulic gold mining and...Read More
Bay margins are often mucky, fertile, out-of-the-way places. In the last decade, however, the edges of the San Francisco Bay have caught the attention of San Francisco Estuary Institute scientists as unexpected sources of pollution--and, potentially, of solutions. “The idea that you could make a big difference by just cleaning up the margins is attractive because it scales down the problem quite a bit,” says Phil Trowbridge of the Regional Monitoring Program. Historically, scientists considered the Bay akin to a...Read More
According to data from the Regional Monitoring Program, common coatings and repellants used in textiles for clothing and furniture are sticking around in San Francisco Bay water, sediment, and wildlife. “The reason for the lack of declines is not clear,” says researcher Meg Sedlak of the San Francisco Estuary Institute. Some early environmental offenders in this line of fluorinated chemicals (PFASs) have been banned, including one used in the cookware coated with Teflon. “In 2006 and 2009, the levels of...Read More
“White sturgeon are a popular species, so we want to keep a close eye on contaminants in their tissues.” Recent RMP studies have unearthed a few new interesting things about sturgeon - first that selenium keeps turning up in specimens from certain areas, and second that testing may not have to be deadly. Growing up to 20 feet long and living up to 100 years, today’s living fish have become valuable for the stories that they tell.Read More
What some might call a regulatory burden on industry, commerce, and American greatness, others might call the road to success. Jay Davis, a serious guy, doesn’t crack a smile when he describes the Bay Area’s Regional Monitoring Program as “a beacon of environmental protection.” It may sound a little over the top, for a PhD who ran the program for more than a decade, but all you have to do is fact check. Ask some of the oil refineries, power...Read More
It was past midnight when Lester McKee pulled the plug. He’d been watching the weather for days on screen, looking for the perfect storm of conditions he needed to send his team out to sample the Guadalupe River in Santa Clara County. He knew there’d been enough rain already to saturate the soil and surpass annual averages. Zooming in on real-time sensors aimed at Santa Clara Valley Water District reservoirs, he could see they were full enough to spill downstream....Read More
Toxic flame retardants quickly declined in Bay-caught fish, once banned, but legacy mercury persists, according to the most recent year of sampling. As the region’s collaborative monitoring program for Bay contaminants — the RMP — arrives at its 25th birthday, its long-term commitment to consistent data collection for the purposes of targeted environmental management is showing its mettle. The RMP has been catching and testing a wide array of species of popular sport fish, ranging from giant sturgeon to tiny...Read More
It’s hard to go to the big box pet store and not stumble over the flea control displays. Most pet owners have dabbed or squirted Frontline or Advantage between their cat’s shoulder bones or onto the back of their dog’s neck, but who would guess this same chemical would make its way off our pet’s fur, down the drain, through wastewater treatment, and into the Bay? Apparently all the petting and shedding and subsequent washing of hands, doggies, and floors...Read More
San Francisco Bay is becoming less opaque as the sediments power-washed into the Estuary by miners so long ago gradually disperse. This lets sunlight penetrate deeper into the water, creating more favorable conditions for the kind of problematic algal blooms that can shut down crab fisheries and keep people and their pooches out of the water. Scientists have collaborated on some new computer models, however, that may help them predict where and when nutrients, like nitrogen and phosphate from discharges...Read More
Birds’ eggs don’t lie. Just as thinning eggshells once revealed how DDT was affecting peregrines and pelicans, the eggs themselves are now telling scientists how long-lived some contaminants are in the Estuary and where they are the most problematic. A report just published by the Regional Monitoring Program for Water Quality in San Francisco Bay (RMP) summarizes contaminant concentrations in eggs collected between 2002 and 2012 from two fish-eating species high in the Estuary food chain, double-crested cormorants and Foster’s...Read More
If and when El Niño decides to dump a big storm on the Bay Area — even at 2:00 am on a Saturday night — SFEI’s Lester McKee and Alicia Gilbreath and their team are ready to pull on their parkas and dash out to take water samples. Last September, stakeholders in the Regional Monitoring Program decided they would be remiss if they did not try to measure some high priority pollutants during an El Niño year. “With plenty of...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.
