  • 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.
  • 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."
