Southern California’s Fog Falls Victim to Concrete

Summertime fog that helps keep coastal southern California cool and damp appears to be melting away, and scientists who have documented nearly 70 years of its decline think they can explain why: concrete.

The urban heat island effect, the phenomenon of cities warming faster than surrounding countryside, is a main culprit for a two-thirds reduction in the number of foggy mornings in Los Angeles since 1948 — a trend that’s expected to intensify as greenhouse gas pollution pushes temperatures upward.
