We discuss two climate change-related studies released this week. First, if your favorite flower is blooming earlier than usual, a new UC Berkeley study may help explain why. Seasons are now arriving two days earlier. Meanwhile, trees in old-growth forests in the Western U.S. are dying at double the usual rate, and researchers say climate change may be to blame.
