Fog decline threatens US redwoods

Scientists in California say a drop in coastal fog could threaten the state’s famed giant redwood trees.

Their study, published in the Proceedings of the National Academy of Sciences, says such fog has decreased markedly over the past 100 years.

The weather records analysed come from the US National Climate Data Centre.

“Fog prevents water loss from redwoods in summer and is really important for the tree and the forest,” said research co-author Professor Todd Dawson.
