New predictions on sea level rise

Though many scientists will find the results overly optimistic, another new study confirms the undeniable reality of rising sea levels as a result of global warming. California’s Marine Life Protection Act “Initiative” failed to address any issues related to rising oceans.  (w/thanks to Heraldo)

“Northern California, Oregon and Washington can expect a less dramatic increase — about 4 inches by 2030 and 2 feet by 2100 — because seismic activity is causing land to rise north of the San Andreas Fault, offsetting increasing sea levels, and drop south of it. The fault runs out to sea at Cape Mendocino.”  from:  LINK

As the world continues to warm from climate change, most of California — including San Francisco Bay — will see a greater rise in sea level than other parts of the planet, according to a prominent national study released Friday.

The report, from the National Academy of Sciences, found that the impacts of melting ice and warming, expanding oceans will hit California harder because most of the state’s coastline is slowly sinking due to geological forces.

Ocean levels south of Humboldt County will rise up to 1 foot in the next 20 years, 2 feet by 2050, and up to 5 feet by 2100, the study showed.

San Francisco Bay already has risen about 7 inches in the past 100 years, as measured by the tidal gauge at Fort Point, under the Golden Gate Bridge.

“We shouldn’t be debating this any more,” said Gary Griggs, a coastal geologist at UC Santa Cruz who served on the committee that issued the 274-page report. “Let’s start thinking realistically about the future, and plan so we minimize our losses.”
