SAN FRANCISCO — Environmental advocates in Northern California plan to take photographs of some of the highest tides of the year to draw attention to what climate change could do decades from now.

The so-called king tides are expected to peak during the next several days, with surges over 9 feet in some areas. The phenomenon is caused by a unique alignment of the sun, moon and earth.

The tides already produced some minor flooding in low-lying areas.

The goal of the King Tides Initiative is to preview what rising sea levels could bring in 2070.
