Warming-induced shifts in vegetation phenology have substantially affected the terrestrial energy balance as well as carbon and water cycles, which in turn exert biophysical and biogeochemical feedback to the climate system. Spring phenology of temperate and boreal tree species has advanced significantly with warming in recent decades, but most previous studies focused on a single phenophase, such as flowering or leaf unfolding.
