Fog decline threatens Redwoods

According to an article in Wired, the average daily hours of fog has decreased by 3 hours during the past century. Redwoods have developed the ability to get as much as 40% of their needed water from fog, as it would otherwise not be possible to get water from the roots all the way to the tops, as much as 300-400 feet higher. The study, published in the Proceedings of the National Academy of Sciences, found that on foggy days, the trees lost less water to the air and help the trees survive the drier summer months.

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.
