Climate change is heating, salinizing, and expanding the San Francisco Estuary, a review of nearly 200 scientific studies concludes.

Sea level rise, changing snow and rainfall patterns, and warmer waters are some of the changes already observed in the Estuary and expected to continue through the rest of the century as greenhouse gas concentrations rise. Changes to water are at the heart of the documented and further expected impacts; there’s less of it entering the system overall, but more arriving in torrential bursts, and more saltwater creeping inland from the Bay. The scope of the research is expansive even for a review article, in part because climate changes aren’t happening in isolation from other threats and habitat impacts. Writing in San Francisco Estuary and Watershed Science, the authors attempt to summarize not only all known research about climate change...

Although the Covid-19 pandemic and attendant economic cataclysm have tripped up some ambitious plans for funding climate resilience in California, other measures to integrate adaptation and planning are still on track.

In July, the Metropolitan Transportation Commission and the Association of Bay Area Governments released the draft of Plan Bay Area 2050, a 30-year plan to guide growth in the nine-county region. “The biggest new integration in the plan is a set of investments to protect our Bay and ocean shorelines from rising sea levels,” says MTC’s Dave Vautin. The plan calls for just under $20 billion in investments ranging from seawalls and traditional levees to horizontal levees and wetland restoration to protect communities and infrastructure. “The draft showcases how that system of infrastructure improvements could protect 98% of all homes at risk over the next 30-years, as well as all major highways, railways and the vast majority of offices and...
