Like the Bay Areaâs salt ponds, cranberry farming originally involved creating an artificial environment from a natural wetland through the installation of dams and weirs. The cranberriesâa plant native to North America that naturally grows as a vineâwere then trained to grow in mats on the waterâs surface. A project on Tidmarsh Farms in Plymouth, Massachusetts included redirecting a natural stream that had been diverted into an agricultural canal back into its original channel and planting 6,000 Atlantic white cedars to âjumpstartâ the native wetland restoration. The farm is approximately 10 feet above sea level, says Alex Hackman, Restoration Specialist with the Massachusetts Department of Fish & Game, so the tides arenât yet connecting with the new wetlands. But as sea level rises, that could change. In the meantime, native fish like alewivesâa river herringâand eels are already returning to the stream. Hackman says there are approximately 14,000 of acres of cranberry farms in his state that could potentially be restored. LOV
Two Massachusetts restoration projects have recently returned close to 740 acres of commercial cranberry bogs to wetlands.

Ever since the state and federal water projects were built in the 1930s and 1940s, California has captured snowmelt in foothill reservoirs, and moved the fresh water from dam releases and river outflows to parched parts of the state via aqueducts hundreds of miles long. A convoluted system of ancient...
Though the Clean Water Act did an amazing job of reducing wastewater and stormwater pollution of the San Francisco Estuary, some contaminants remain thorny problems. Legacy pollutants like mercury washed into the watershed from upstream gold mining, PCBs from old industrial sites, and selenium from agricultural drainage in the San...
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 â or the ministers or mayors of dozens of cities and countries â 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 Yukonâs Arctic National Wildlife Refuge who pleaded with us not to enter his sacred lands with our drills and dependencies; all the women â swathed in bright patterns and head-scarfs â who kept punching their hearts. âMy uncle in Uganda would take 129 years to emit the same amount of carbon as an American would in one year,â said Oxfamâs Winnie Byanyima.
âOur janitors are shutting off the lights you leave on,â 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. âThe notion that you can either do good or do well is a myth we have to collectively bust,â said New Jersey Governor Phil Murphy whose state is investing heavily in offshore wind farms.
âClimate change isnât just about risks, itâs about opportunities,â said Blackrock sustainable investment manager Brian Deese.
But it wasnât 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 couldnât help thinking of Dr. Seuss and his truffala trees. Jane Goodall, over 80, is as fierce as my Lorax. Or my daughterâs Avatar.
Analyzing my take home feeling from the event I realized it wasnât the usual fear â killer storms, tidal waves, no food for my kids to eat on a half-baked planet â nor a newfound sense of hope â Iâve 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.
âWe must be like the river, â said a boy from Bangladesh named Risalat Khan, who had noticed our Sierra watersheds from the plane. âWe must cut through the mountain of obstacles. Letâs be the river!â
Or as Harrison Ford less poetically put it: âLetâs turn off our phones and roll up our sleeves and kick this monsterâs ass.â
4th California Climate Change Assessment Blues
by Isaac Pearlman
Since Californiaâs 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 yearâs Mendocino Complex fire achieving the dubious distinction of the largest in state history. Californiaâs 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. Californiaâs 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 stateâs 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, Californiaâs 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 isnât an urban smog-filled city but in the Imperial Valley, where toxic dust from Salton Sea disaster chokes communities â 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 regionâs seven million people and $750 billion economy (almost one-third of Californiaâs total) is predicted to be increasingly beset by more âboom and bustâ irregular wet and very dry years, punctuated by increasingly intense and damaging storms.
Unsurprisingly, according to the report the Bay Areaâs 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.
âAll Californians will likely endure more illness and be at greater risk of early death because of climate change,â bluntly states the statewide summary brochure for Californiaâs climate assessment. â[However] vulnerable populations that already experience the greatest adverse health impacts will be disproportionately affected.â
âWeâre much better at being reactive to a disaster than planning ahead,â said UC Berkeley professor and contributing author David Ackerly at a California Adaptation Forum panel in Sacramento on August 27th. âAnd it is vulnerable communities that suffer from those disasters. How much human suffering has to happen before it triggers the next round of activity?â
The assessmentâs data is publicly available online at âCal-adapt,â where Californians can explore projected impacts for their neighborhoods, towns, and regions.
The results are alarming for our stateâs 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.
