Study Predicts Rising of Sea Levels Off of West Coast
A new report is giving planners their best look yet at how melting ice sheets and warming oceans associated with climate change will raise sea levels on the West Coast.
The report issued Friday by the National Research Council is generally consistent with earlier global projections, but trains a finer lens on California, Oregon and Washington.
It says most of California can expect sea levels to rise about six inches by 2030, ramping up to three feet by 2100. Northern California, Oregon and Washington can expect less - about four inches by 2030 and two feet by 2100.
The difference is that seismic activity is causing land north of the San Andreas Fault to rise, offsetting increases in sea level.
The report was commissioned by states and federal agencies.
