Controversial SF Bay Development Plan Dead in the Water — For Now

Saltworks, in Redwood City, would have built thousands of homes in salt ponds on the Bay

Salt ponds in Redwood City where the new Saltworks development is proposed.

The low-lying land along the Bay in Redwood City has been the center of a climate controversy: should the salt ponds that have been producing salt for Cargill for decades be turned into housing, or back into wetlands? Supporters of the development point out that Silicon Valley needs more housing. Supporters of the wetlands respond, birds need a place to land, too — plus, the wetlands will provide a much-needed buffer as the sea level rises.

Now, the fight is on hold: DMB Associates, the developer that is working with Cargill on a plan to turn nearly 1,500 acres of salt ponds into Saltworks, has officially withdrawn its application from the City Council of Redwood City. That’s after an ad hoc subcommittee of the council recommended that the application be denied at this coming Monday’s meeting.

NOAA’s Margaret Davidson: Watching the Coasts, Preparing for Change

Tonight: The latest in our series of TV interviews with climate change thought leaders

As head of NOAA’s Coastal Services Center, Margaret Davidson has her eye firmly on the future of the country’s coasts, and the threats imposed from rising seas and more extreme weather. Davidson is based in South Carolina, but is a close watcher of California, where coast and climate may be on a collision course.

Climate Watch Senior Editor Craig Miller spoke with Davidson about sea level rise and the California coast. Their conversation will air this evening on This Week in Northern California, on KQED Public Television 9.

Here’s a clip that’s not included the TV broadcast.

Storms and Rising Seas Present New Threats to Unstable SoCal Peninsula

The geologic features of the Palos Verdes Peninsula make it a hotspot for landslides

Bureau of Engineering / City of Los Angeles

November's sea cliff failure took out 600+ feet of roadway and sidewalks.

The latest Palos Verdes Peninsula slide may calve, and the main slide mass is likely to keep “moving oceanward.” That’s according to a preliminary draft of a geotechnical study commissioned by the City of Los Angeles in early winter, but that’s the extent of the news for now. The same report says based on the studies completed to date, the risk of landslide movement behind last November’s slide — landward into a nature preserve and beyond a new chain link fence — is low.

That’s just the latest from an area southwest of downtown L.A. that has been generating geological news for decades. According to a landslides map by the California Geological Survey, the PV Peninsula boasts 175 slides, 49 of them active.

Politics, Climate Change and Human Rights in the Maldives

The Island President tells the story of the former president’s fight for climate action

President Nasheed at the Copenhagen Climate Summit 2009.

The new documentary, The Island President, depicts former-president Mohamed Nasheed’s efforts to draw the world’s attention to the plight of his country. The islands that make up the Maldives lie barely above sea level. With a few feet of sea level rise, they will be inundated.

John Shenk, the San Francisco-based director of the film, was a guest on KQED’s Forum last week. He talked about how Nasheed, the country’s first democratically-elected president (he resigned in February), and a former human rights campaigner, became a climate change activist.

“He took office and immediately plunged into the climate debate,” Shenk said. “He’s framing the climate debate as a human rights issue. He very much sees the climate fight, the struggle against climate change, as an extension of his fight for democracy.”

In a quote from the film, Nasheed explains: “When we came to power we thought we won the fight. After twenty years, we thought, ‘Look, OK, we’ll have a happy life.’ But we had our first few cabinet meetings, and most of the pending issues were climate change issues. Weather patterns are changing, and that’s having a very big impact on fisheries. We have lost a lot of the shoreline. Our islands are going to be flooded.”

Coastal Erosion in SF Prompts Planning and Debate

City planners are looking at ways to reconfigure the city’s western edge

One of the challenges for the Ocean Beach Master Plan is how to slow the erosion of Ocean Beach's sandy cliffs.

San Francisco’s Ocean Beach is eroding; that’s not up for debate. But planners are still figuring out the best way to handle the erosion that’s already happening, and how to prepare for sea level rise. And that’s going to take a lot of planning: Ocean Beach itself is part of the Golden Gate National Recreation Area, managed by the National Park Service, but there are also the nearby residential neighborhoods to consider; plus the Great Highway, a wastewater treatment plant, the parking lot at the beach, endangered species, surfers, dog walkers and the occasional hopeful sun bather.

The Ocean Beach Bulletin, a local news site and one of KQED’s News Associates, has been covering the development of the new plan for San Francisco’s coastline, called the Ocean Beach Master Plan, which will attempt to address erosion and rising sea levels, while balancing the myriad social and environmental needs.

Over the weekend, the New York Times weighed in, too:

Are You in Harm’s Way? Rising Seas Increase Flood Risk in California

San Francisco Bay, the Delta and Southern California are most susceptible in the state

Climate Central

Sea level rise compounded with storm surges and high tides could raise the water level by four feet.

Tens of thousands of Californians will be placed at risk in the years to come as sea levels continue rising along the California coast. The official planning parameter for the San Francisco Bay Area acknowledges a potential 16-inch rise by 2050. But with help from high tides and storm surges, it’s not likely to stop there. A new tool from Climate Central maps out which cities, neighborhoods, and even streets, will be most affected.

The state’s Cal-Adapt site offers a similar tool but the East Coast-based science education group, Climate Central has added a new layer: population. According to Climate Central, which is a content partner with Climate Watch, there’s a one-in-six chance that under the right conditions — sea level rise, plus storm surge, plus high tides — the sea could rise four feet by 2030 in the Bay Area. That effects not just the coast, but also cities around the Bay and farther inland, in the Sacramento-San Joaquin Delta. The cities with the most people at risk are San Mateo, with 35,000 people living in areas that would be flooded under that scenario, and Stockton, with more than 72,000.

In Southern California, the threat is farther off, but by 2060, there’s a one-in-six chance of sea levels topping a four-foot increase with help from a storm surge. If that happens, more than 44,000 people in Huntington Beach would be in harm’s way, and 11,000 in LA.

New List Highlights California’s Birds Most Threatened by Climate Change

Shorebirds, especially, are imperiled by rising seas and habitat loss

Molly Samuel

Birds like the Black Oystercatcher that live along the shoreline are threatened by rising sea levels.

More than one hundred species of California’s birds are vulnerable to the effects of climate change. Scientists at the California Department of Fish and Game and PRBO Conservation Science examined nearly 400 species and subspecies for a study, released today. Of those, 128 are at risk.

San Francisco Bay is home to the majority of the most vulnerable birds. “That’s primarily because of sea level rise and also because there are already so many imperiled species that use that habitat in the bay,” says Tom Gardali, an ecologist is PRBO Conservation Science.

Climate Adaptation and Unintended Consequences

Radio documentary explores the social and economic impacts of adapting to climate change

Rising seas will irrevocably change life near the San Francisco Bay. That’s the premise of RISE: Climate Change and Coastal Communities, a three-part documentary by independent producer Claire Schoen. The final part, “Chuey’s Story,” airs this evening at 8 pm on KQED 88.5 FM.

Chuey Cazares works as a fisherman out of the South Bay town of Alviso. Adapting to climate change may save his town, but it's having unintended consequences for his livelihood.

There’s an old adage that goes something like this: “The human capacity to create technology exceeds our capacity to understand its impact.”

Lots of people have referred to this idea, Einstein perhaps most famously when he said, “The unleashed power of the atom has changed everything save our modes of thinking and we thus drift toward unparalleled catastrophe.” Splitting the atom certainly brought us the promise of unlimited energy to run industry and military might to protect the world from Hitler. It also brought us a nuclear North Korea and Fukushima.

Help Document Bay Area High Tides

King tides return to the Bay Area, augmented by a long-awaited winter storm.

Jack Gregg

High tide at Pier 14 in San Francisco during the winter of 2011.

No one knows exactly how much sea level rise the San Francisco Bay Area can expect from climate change, but king tides — extremely high seasonal tides — may give insight into what could be normal in the future.

Starting today and continuing through Sunday, king tides are expected in the morning hours around the Bay Area. Recent rainstorms and the accompanying runoff will likely make these tides even bigger. The California King Tides Initiative is again asking for citizens to document the visual effects of king tides and add them to a Flickr photo pool to help give a perspective on how sea level rise might change local landscapes.

Sea levels have risen about eight inches in the last century and the San Francisco Bay Conservation & Development Commission (BCDC) has warned that the area should be ready for 16 inches of sea level rise by mid-century.

Climate Change and Coastal Communities: Facing the Rising Tide

As the water rises, a documentary maker ponders why people aren’t more concerned

Rising seas will irrevocably change life near the San Francisco Bay. That’s the premise of RISE: Climate Change and Coastal Communities, a three-part documentary by producer Claire Schoen. The second part, “Facing the Rising Tide,” airs this evening at 8 pm on KQED Public Radio.

Opinion by Claire Schoen

Steve Mello's family has been farming this land in the Delta for generations. Climate change may prevent his son from carrying on the family legacy.

I recently dug out an old letter which I had written to my Dad back in 1982. “Have you heard about this thing called Global Warming?” I asked.

Back in the 80’s, I was already aware of what is now referred to as “climate change.” So why is it that so few Americans understand this threat today?

In fact, America is in retreat on the subject. According to Pew Research, the number of Americans who believe the planet is warming dropped by 20 percent from 2006 (79%) to 2010 (59%). “Believe.” As if this scientific phenomenon were a belief system, a question of faith.
