An analysis of newly available climate data shows that summer fog along the California coast has declined significantly in the past century, though it is unclear whether this is a natural variation or a result of human activity. The new report links summer high pressure cells above the northwest California coast to frequent fog. When the cells are weak, fog escapes inland and coastal temperatures rise. This could affect redwoods, which need high humidity.
