It suddenly became fall (at least in New York City, anyway). A new chill in the air used to mean beautiful crimson, gold and burnt orange leaves.
But now, scientists say climate change is having an irreversible effect on fall foliage: leaves will change color later, thanks to rising carbon dioxide levels, and their colors may become richer.
In the September-October issue of Audubon, Les Line discusses the future of this awesome display—something to contemplate as you look out your window this autumn day.
