Last week’s superstorm Sandy demonstrated on a grand scale the kind of turmoil extreme weather events can bring to coastal areas.
Rising sea levels bring high tides and high waves to our shores. It is no longer possible to halt all the impacts coming with climate change. It is time to start adapting to those changes that are now inevitable.
The public media project RISE looked to the San Francisco Bay Area for answers. These are the stories of men and women living along the water: a fisherman, a farmer, a developer and others. We see the bay from various perspectives. A kayaker brings us eye level to levees at the water’s edge. An urban planner considers how filling in wetlands has increased the flood risk. An architect suggests one plan that may keep the waters in check. Their responses can provide a model for people everywhere in the face of this growing global crisis.
Sea level rise is an effect of global climate change. How does this work? As oceans absorb heat from carbon pollution, the waters expand. As glaciers melt, more water pours into the oceans. Climate disruption causes higher tides and storm surges. The result: more and more flooding for cities like San Francisco.
While we must stop adding greenhouse gases to the global atmosphere, conservation and green technologies can no longer completely halt the impact of climate change on people, wildlife, and the lands and waters we depend on. Adapting to climate change is also necessary. This story is about creative solutions to deal with sea level rise for cities at the waters’ edge.
Steve’s pickup truck bumps along a narrow dirt road running along the top of a levee. This is Tyler Island, in the San Francisco Delta, where Steve is a third generation farmer; his son is being raised as the fourth. But Steve’s land lies 20 feet below sea level and the levees protecting it from the surrounding waters are threatened by sea level rise. For Steve, retreat is not an option. He has a family legacy to preserve.
In the development rush of the 1960’s 40% of the San Francisco Bay was filled in. One result was Foster City, built completely on wetlands and sitting at sea level. But rising seas, higher waves and storm surges, brought on by climate change, threaten the levees in front of this city. T. Jack Foster Junior, who built this town, paints a rosier picture of the area’s future.
Chuey Cazares is part of a large extended Chicano family, living in the tiny hamlet of Alviso. Nestled in between salt ponds, on the southern tip of San Francisco Bay, Alviso is at risk of flooding from both the creeks above and the Bay below. Converting the salt ponds back to their original wetlands could save this town.
San Francisco Bay is the largest estuary on the Pacific coast of the Americas, and it is a place of great biological diversity. We journey underneath its surface to swim with the harbor seals; we look overhead at a million migratory birds; and we explore marshlands along its shores.
