Warmer Temperatures Drought Delaying Or Eliminating Fall Foliage In Some Parts Of U.S.
Peak fall colors are dependent on the weather and can be jeopardized by changes in the environment, Paul Schaberg, a research plant physiologist with the U.S. Forest Service based in Burlington, Vermont, said. Warm temperatures can keep leaves green longer, and dry summers can put stress on trees and cause their leaves to avoid fall colors altogether, according to a 2003 study in Tree Physiology that Schaberg co-wrote. “If climate change is going to mean significant drought, that means trees are going to shut down, and many trees are just going to drop their leaves,” Schaberg told the AP....
