California Rising Sea Levels
On March 23, 2019 in Mother Jones, Nick Bowlin reported “The Vulnerability of California’s Coast Is Terrifying.” Patrick Barnard of the US Geological Survey headed the study. Pacific storms can surge several meters on top rising sea levels of at least one or two meters by 2100. “A quarter-meter would endanger more than $30 billion in property—and more than 150,000 Californians””In that scenario, researchers expect that $150 billion in property and 600,000 residents would be impacted by flooding. And if sea level rise approaches three meters by 2100, an unlikely but possible scenario, more than 3 million people would be exposed to flood risk.”
Brett Milligan of University of California-Davis “San Francisco Bay would need to spend up to $450 billion on climate-adaptation projects—including higher seawalls, infrastructure protections, wetland and shoreline restoration, flood control and more—to defend itself against an extreme storm if sea levels rise by two meters.””Cities and officials need to realize that retreat from the coast is inevitable in some areas, and that retaining all low-lying areas and current infrastructure is unlikely” said Milligan. “There are lots of cities thinking about this study and assessing their vulnerability,” said USGS oceanographer and study co-author Juliette Finzi Hart.
“Rich homeowners may be able to rebuild, or move to higher ground, Barnard said. But others might lack the financial capacity to rebuild or relocate. Already, natural disasters have been shown to disproportionately impact economically disenfranchised communities and people of color. Milligan called it the hardest question: “How are we going to provide equitable solutions?”
