Biosphere and atmosphere form a complex system in which climate influences ecosystems, which then provide various feedbacks to affect climate. As we try to assess the place of plants in this system, an ever-increasing number of paleobotanical studies are focusing on the interactions between forest ecosystems and climate through geologic time. The phenomenon of forest growth at very high latitudes (>70° latitude) during periods of greenhouse climate is especially receiving attention, as it may provide a proxy for boreal forest growth during future climate warming (e.g., Taggart and Cross, 2009; Swann et al., 2010). Detailed studies of fossil...
