Theory and "wouldn't be surprised" vs Actual fog measurements The first article is based on actual measurements: "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. The second article is merely speculation: -The theory, then and now, is that the hotter the Central Valley gets, the greater the temperature and pressure gradients between the inland and coast will be - therefore forming more fog... UC Santa Barbara researcher Park Williams likewise adds that while the ocean is warming, the coastal waters are colder this year. He considers the possible effects of global warming along the Pacific coast to be the "million-dollar question," but wouldn't be surprised if foggier summers are in the offing.
