Study shows coastal fog is thinning.

Global warming is taking a toll on California's coastal fog, British newspaper The Telegraph reports.
Over the past century, the state's shoreline fog has become about one-third thinner, equal to about three hours of cover per day, according to a study led by James Johnstone of the University of California, published in Proceedings of the National Academy of Sciences.
As the planet heats up, the temperature difference between the land and the ocean's surface - which creates the Peninsula's "June gloom" and the mystical foggy vistas of Big Sur - is decreasing, the scientists report.
The result may be brighter summers, but scientists also warn of impacts on fog-dependent plant life, including coastal redwoods.
