San Francisco Chronicle - Get ready for foggier summers (6 July 2009)

The Bay Area just had its foggiest May in 50 years. And thanks to global warming, it's about to get even foggier.

That's the conclusion of several state researchers, whose soon-to-be-published study predicts that even with average temperatures on the rise, the mercury won't be soaring everywhere.

"There'll be winners and losers," says Robert Bornstein, a meteorology professor at San Jose State University. "Global warming is warming the interior part of California, but it leads to a reverse reaction of more fog along the coast."

The study, which will appear in the journal Climate, is the latest to argue that colder summers are indeed in store for parts of the Bay Area.

Telegraph - Fog over San Francisco thins by a third due to climate change (15 Feb 2010)

The sight of Golden Gate Bridge towering above the fog will become increasing rare as climate change warms San Francisco bay, scientists have found.

The coastal fog along the Californian coast has declined by a third over the past 100 years – the equivalent of three hours cover a day, new research shows.

And it is not just bad for scenery, the reduction in the cooling effect of the fog could damage the health of the huge Redwood Forests nearby.

"Since 1901, the average number of hours of fog along the coast in summer has dropped from 56 per cent to 42 per cent, which is a loss of about three hours per day," said the study leader Dr James Johnstone at the University of California.

He said that it was unclear whether this is part of a natural cycle of the result of human activity, but the fog is receding because of a reduction in the difference between the temperature of the sea and the land.

"A cool coast and warm interior is one of the defining characteristics of California's coastal climate, but the temperature difference between the coast and interior has declined substantially in the last century, in step with the decline in summer fog," he added.

His findings, published in the journal Proceedings of the National Academy of Sciences, came from weather records kept at airports along the coast.

Professor Todd Dawson, co-author, said the decline could be disastrous for the nearby ecosystems.

"Fog prevents water loss from Redwoods in summer, and is really important for both the tree and the forest," he said. "If the fog is gone, we might not have the Redwood forests we do now."
