http://www.wired.com/wiredscience/2010/02/fog-decrease-threatens-coastal-redwoods/"Over the last century, new research suggests the average daily fog has decreased more than three hours, causing the coast redwoods to lose more water in the dry summer season, leaving them more susceptible to drought.
“Redwoods are an iconic species and we all love them, but I think it’s important to note that lots and lots of species depend on fog,” said climate scientist Phil Duffy of Climate Central in Palo Alto, California, who was not involved in the study. “So if you really do increase or decrease the fog, then that will have effects on whole entire ecosystems in these coastal hills.”"

"The team can’t say for sure whether human-caused climate change is a culprit in the disappearing fog, but “it seems likely that it may be the case,” Dawson said. To link the drier coastal air to global climate change, the group would have to do an “analysis of fog everywhere around the world, and how it’s changed everywhere around the world, to say OK, there’s this general global pattern.”
Some emerging evidence does suggest the vanishing fog may be more than a California phenomenon. Early studies show some of the formerly foggy coasts off of Chile and South Africa have become less so in recent years, Dawson said."
Chalk that up in the "Oops" category, eh?
