CALIF. SEA LEVELS RISING AT A RAPID RATE: 67% OF BEACHES COULD BE LOST BY END OF THIS CENTURY

 

By Miriam Raftery

April 26, 2017 (San Diego) -- Sea levels rising much faster than expected could submerge over two-thirds of the state’s beaches by the end of this century, also forcing damage and relocation of major infrastructure. Those are among the disturbing findings of an updated  state-commissioned report, “Rising Seas in California.”  Sea levels could rise 30 to 40 times faster than in the last century, raising the sea level 10 feet after 2050 under the most severe scenario.

EARTHTALK®: SEA LEVEL RISES NOT LETTING UP ANYTIME SOON

 

July 29, 2013 (San Diego) -- Dear EarthTalk: Hurricane Sandy brought more sea water onto shorelines than I’d ever witnessed before and many communities near where I live are now being required to raise their homes up. What is the prognosis for sea level rise in the years immediately ahead?

Since sea level measurements were first recorded, in 1870, global averages have risen almost eight inches. The annual rate of rise has been 0.13 inches over the past 20 years, which is close to twice the average from the previous 80 years. Future estimates for sea levels vary according to region but most Earth scientists agree that sea levels are expected to rise at a greater pace than during the last 50 years.
