For the next month the California coast will be hit by high tides called “king tides.” This annual occurrence is the result of the gravitational pull between the sun and the moon. I took this shot of Carmel Beach right before sunset yesterday. Note how the tides have carved a ravine out of the beach-. The tides will be at their highest tomorrow when the moon is full. People are asked to take photos to get an idea of how the coast will look as the result of climate change.
