Not enough, apparently. Not till JimRob has beachfront in Fresno.
I notice that your article on sea level rise focuses on almost anything except sea level rise.
One thing it doesn't mention, and its pretty important, is the silt depositing in the bay from the rivers feeding it. The bay is filling in at a faster rate than the sea is rising. They have ports and shipping, but they have to dredge channels into the silt to keep shipping lanes open. The bay's future is to become a marsh, not flodded.
