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.

Guests:
Phil van Mantgem, research ecologist at the U.S. Geological Survey and co-leader of the research team that conducted the forest mortality study
Inez Fung, co-author of the seasonal temperature study, professor of earth and planetary science, environmental science, policy and management and co-director of the Berkeley Institute of the Environment at UC Berkeley
Craig Miller, senior editor of KQED's Climate Watch
