Heat Wave: Trees Change Colors Early From High Temperatures (VIDEO)

As summer heat waves continue to grip the nation in what is on track to become the hottest year on record, some cities are starting to witness unusual side effects. This clip from CNN shows how leaves in Little Rock, Arkansas are appearing to take on their fall colors way ahead of schedule, unable to brace the harsh temperatures.

Bryan Roseberry of Horticare Nursery tells CNN, "When you start to see your trees changing colors and falling leaves, yeah, you know it's hot."
