SAN FRANCISCO (December 13, 2012)--Environmental advocates in Northern California plan to take photographs of some of the highest tides of the year to illustrate what climate change could do decades from now.
The so-called king tides are expected to peak during the next several days and could surge more than 9 feet in some areas.
The phenomenon is caused by a unique alignment of the sun, moon and Earth.
The tides have already produced some minor flooding in low-lying areas.
The goal of the King Tides Initiative is to provide preview what rising sea levels could bring in 2070.
