Seven foot rise in California sea levels projected

 SF Weekly -Sea levels on the California coast could rise as much as seven feet by 2100 and put tens of thousands of vulnerable San Franciscans at risk of daily flooding, according to a new report from the California State Legislative Analyst’s office.

...California sea levels are projected to rise half a foot by 2030 and up to seven feet in the next 80 years, although the report notes that weather events such as storm surges, exceptionally high “king tides,” and El Niño events could make the actual sea level rise greater. Rising sea levels will cause coastal flooding, erosion of coastal cliffs and beaches, and rising groundwater levels.

Between $8 billion and $10 billion worth of existing property in California will likely be underwater by 2050, the report states, and an additional $6 billion to $10 billion will be at risk at high tide. A six-foot sea level rise, combined with recurring annual storms, would put over 480,000 California residents and $119 billion in property value. Five feet of sea level rise would put 55 percent of coastal habitats in California at high risk of flooding and damage. Rising sea levels could also contaminate drinking water with saltwater or toxic materials.
