Lovers of Fog

I'm not a huge fan of fog - it's cold and wet and it makes driving dangerous.

But it's also a key component of the ecosystem that makes Redwood trees possible. Redwoods, the tallest and one of the most massive tree species on Earth, grow only in the Pacific northwest of the United States, primarily in northern California.

The weather on the coast here ranges between 40 and 60 degrees Farenheit all year round.
Redwoods mostly grow a mile or two...from the coast, but never more than 50 miles...from it. In this temperate but humid coastal zone, the trees receive moisture from both heavy winter rains and persistent summer fog. The presence and consistency of the summer fog is actually more important to overall health of the trees than heavy precipitation.

So, fog: not so good for driving, necessary for happy Redwoods. The problem?

Per Wired, a recent study shows that "Over the past 58 years, the coastal fog has decreased by about 1.3 hours a day...[and] by about 3.5 hours a day over the last century from 13.5 hours to about 10 hours."

The study did not identify a specific cause for the drop in fog levels but indicated that climate change might be responsible.

But that's just crazy talk. My bet is on huge, ravenous, fog eating sea monsters from off the coast.
